Bitcoin Forum

Hi, I'd like to work on a larger bitcoin based game and this small game is my technology test and ping to the people to see if you are interested in something like this.

everything is working as expected, all bugs are fixed.

http://minefield.bitcoinlab.org

http://bitcoinlab.org/sample.png

This was supposed to be a simple coin flip, but I abstracted it a little, allowing users to choose their chances (yup, still nothing new)

winnings are ranging from *1.08 to *23.75

- there is a free play option if you select to bet 0 btc

- referral rewarding has been implemented - for every user you refer to this site, you'll forever receive 10% of that users losses, check out the referrals tab

- the site requires your payments to be confirmed (5 confirmations) before allowing to cash out the winnings

- you dance around the minefield and cash out whenever you'd like.

- in order to prove that the service isn't cheating, I display a sha256 hash of textual representation of the field together with a random string to protect myself from bruteforcing.

- the site doesn't force users to register, but stores their "password" in an url. I will implement optional traditional password logins in the future.

- from technology side, the site is using nodejs and websockets for communication. (you can look at the same user/game from two browsers/computers :D )

I used minecraft textures and sounds :-X I'll need to remove this soon I suppose
I've tested this on firefox chrome and opera, will test it on other browsers as the time passes.

feedback and suggestions are super-welcome.

Sites down for me lol cant try it.

Hm, can you give me more info? down in what way? unreacheable? I've just tested it from few machines and it should work  :-\

no dns info on the host i even tried to look it up with dns services and none of them can resolve the site to a ip.

Ping request could not find host minefield.bitcoinlabs.org. Please check the name and try again.

ah, I'm an idiot. misspelled the domain. fixed :D, thanks

haha yea that helps alot now i can get to the site.

heh, ok, you'll be able to, tomorrow. :)

really like the game even tho i just lost 0.44 lol i didnt know it had sound cause i never have pc sound on lol.

strange, no, I don't take any fees. thanks a lot for the feedback!
I'll repay this and investigate.

implemented now :) button is in the upper right corner.

NA it waset a problem i found out it was the 0.005 fee thats why it droped to lower.

hey, I'm currently having some problems, give me a few minutes to resolve those. there was one player playing :)

done.

I can not deposit. I click "generate" but no payment address ever shows up.

just reloading the page should fix your problem.

longer explanation: I restarted the server for a few times due to updates. if your browser had the page open during that time, it loses the connection in the background so all requests fail silently. I'll make this more oblivious and add autorefresh in the future.

if reloading doesn't help you, you are probably using a browser that my site doesn't support, in that case, if you are up for it, give me its version and I'll check it out :)

I see the sha256 hash, but after my game was over, it didn't show me the actual game string to give the hash any meaning.

aha, the hash becomes clickable after the game is over. I didn't want the text to take too much space, but its not so oblivious yeah.

lol, mojang is going to sue you for using their graphics

:D I'm saying this to myself also. blaaaah I'll change them.

.. they probably wouldn't sue me, but I don't want to piss people off, especially the ones I like :)

Cool, fun game :)

I played on 5 mines for a while after doing this little spreadsheet. (Still lost though :D)

Mines.........	Chance of winning...	Reward...	Reward over time...	House rake over time
3 mines	22/25	1.08	95.04%	4.96%
4 mines	21/25	1.13	94.92%	5.08%
5 mines	20/25	1.19	95.2%	4.8%

23 mines	2/25	11.88	95.04%	4.96%
24 mines	1/25	23.75	92.00%	8%

Just found it works in chrome but not in FF 7.01a (64 Bit Windows Nightly build).

Just deposited and now:
Service Temporarily Unavailable

The server is temporarily unable to service your request due to maintenance downtime or capacity problems. Please try again later.

;( I am certain you will have fixed it soon.

yup, something strange broke, I've restarted it, seems like a glitch in a external lib I'm using, I'll investigate if this repeats. and thanks for the browser info.

yeah, the house is taking 5% :) those differences are due to rounding, I'll disclose the algo if anyone cares.

Yeah its back.. thanks for fixing it so quickly... Money has not showed up in game yet.

Sent 1 BTC to 1ERKxS***. Will wait until tomorrow to see if it shows up.

If those differences are due to rounding, and the cut is always exactly 5% then that means those advertised rewards you display are rounded?

aha, no, that rounding affects the real cut I'm making, what I display is what I use to calculate the winnings.
actually, that multiplication number you see after a game is started is a number received from a server when it creates a new 'field'

(even though there is no need for that, I'm doing the same calculations client side when changing the slider. (so its already 'disclosed' :) exactly the same peace of code is running on the server))

Which is exactly what I used to calculate my table, hence your cut calculation.

Anyway, in other news, I played the '24 mines' game and clicked the same square each time and it took me 53 times to win :) Just my luck.

But the real news was that after I got the right square, and there are only 24 squares left, each with a mine, it should have ended the game, but instead it still lets you pick another square even though 100% of the remaining ones contain a mine.

I'm assuming that's the same for other games too (eg. Play on '15 mines' and pick the 10 free squares, the game should automatically end there, not let you blow your entire winnings by clicking on another square - certain death).

you are right, yes, by saying  "the house is taking 5%" I didn't mean to say you are wrong but to say "yup, the house is taking ~5%, your table is correct" :)


right, I missed this. thanks, I'll implement it.

Something else :)

I just deposited 0.5 btc and I've ONLY been clicking the 0.01 button, but my balance went down somewhat like this:

0.49
0.48
0.469
0.459
0.448
0.438

Like it's also charging an extra 0.001 occasionally for no reason.

Edit: Does each game get recorded in a database? I've played so many games now for 0.01 btc, that all the extra little 0.001 charges have added up to more than 2 bitcents so far.
Balance going down slightly faster than it should be.

yes, javascript can get weird with small floats occasionally, I feared this might show sometimes, I'll need to investigate this a bit. this is serious and I'll make this a priority.

and the games are recorded yeah, I'll repay it to your account

Yeah definitely accuracy issues... my balance is on 0.007 now after only ever playing the bitcent button... it seems to be charging more like 0.0105 for each game.

I've credited your acc with 0.5 btc, its more then needed, but I'm grateful for your good feedback. gonna go to sleep now :)

Thanks very much! But I just logged in and did SHIFT-refresh and it's still on 0.007 balance.

there ya go. forgot to update something :)

Thank you holorga for fixing my account. Man I am a dynamite magnet ;(

hah I'm sorry  :)

I deposited a test value, clicked on play and thats what I see now:

Service Temporarily Unavailable

The server is temporarily unable to service your request due to maintenance downtime or capacity problems. Please try again later.

Apache/2.2.19 (Debian) Server at minefield.bitcoinlab.org Port 80

aha, the server was down for a few minutes, the site is working now.

it was down due to update,
I updated the code to fix a rounding problem mentioned by Alex Beckenham.

server now stores and works with values in 8 decimal places (bitcoin implementation maximum) but it displays money in 4 decimal places so that it doesn't bother users with useless numbers. if somebody cares, I'll add an option to show full precision numbers.

I'm scared of double payments, so now the site requires 5 confirmations before it registers the payment.

I'm working on a better way to handle this, users will be able to play with their unconfirmed bitcoins, but the site will pay it out once they get confirmed. also, you'll be able to set the server to withdraw the money automatically when it gets enough confirmations.

This seems fun. Just deposited 0.05 to try it out. Waiting for 5 confirmations.

EDIT: Lost it all lol

The site seems to be down.  ???

fixed.

and I'm working on this.

I like the idea that you can adjust the amount you win back!

I just deposited 0.05 and it's got 12 confirmations but it hasn't shown up in my balance. :/

Same, I deposited 1btc, it has 10 confirmations now and it does not show up on the site.

I've pm-ed you about this

people, this is one last bug to fix until I can call this app a beta, unfortunately it has a nasty consequence of not registering a payment, it has happened once before. don't hesitate to msg me about this.

I'm onto it and it should be fixed in a few minutes.

found it, I've credited your account, sorry about this.

I won with 24 mines but I only bet like 0.01 lol I was running out to!

When can we withdraw?

if the payment is registered, you can withdraw it.

if you are "user-4e1de994eb71cc8023000078", you are trying to withdraw "[ 333]" instead of just "333", so it results in an error :)

No that's not me, but I might of done that. Oh well spent them all already.

Deposited 0.08, made 0.17 but kept on playing and lost it all. Damn my luck!

for the last few hours, there was a problem with bitcoind dying, so users were unable to generate new deposit addresses. This is fixed now.

Seems as though I lost my BTC. I sent the money last night, kept my browser open, played a bit, left the page, came back and now I've got a different user ID with 0 BTC balance.

Not sure if the user ID's are based on IP or what (my router was reset due to wireless connections not being able to see the network) but is there anyway I can get my coins back? I think users should be able to create accounts or at least register their ID with a password for logins.

hey, user id is based on a argument in a web request called "secret", you can see it in the location bar,
but also, its preserved by the cookie in your browser to prevent easy losing of your login.
if you edit your secret though, and make a request with an invalid one, your cookie is reset and you get a new user. I suppose that this has happened.. I think I'll remove that 'feature' to avoid this in the future.

you can just check out your browsing history and return to a page using a correct link, but if you still have any problems, just give me anything by which I can locate your user, like rough balance, rough ip, the address you payed to, and I'll send you your login link.

The address I paid to was 1Ce1Fichx4R4dHF3Fknbc1C929JgBcsKk5

The reason my info wasn't saved is because I browse with firefox in private mode only so there is no history recorded.

aha, so this was the problem, private mode doesn't remember cookies, and you didn't remember a link that identifies you, so the site didn't have anything to recognize you from, so it created a new user for you. I recommend bookmarking your page so you don't loose it:)

I've pmed you your login.

I've bookmarked the link. Deposited more BTC this time :).

just a stupid bump :)

Hi, the site is having some problems, it will be up in a few minutes.

the site is up.

I've implemented a new payment system!
you can play right away, with unconfirmed transactions, and cash your winnings out when your payments get confirmed.

I'll implement an option to pay out automatically once the confirmations are received.

..I'm slowly building the system up, I want to have everything polished before working on new games.

suggestions are super-welcome :)

somebody won 23 BTC!

they didn't loose much, it was a real gamble :) and yeah, I'd also be way too scared :D

You mentioned creating new games, any ideas on what they are going to be like?
Another gambling game, or a "pay to play" game?

yes, I have some specific ideas.
I suppose they'll be closer to what you'd call gambling :)

"pay to play" games are, in my opinion, something completely different.
with "pay to play" games, a focus is on the games people enjoy, and with bitcoin gambling games, people play those because of the bitcoins :)

if I wanted to help people use bitcoins with real games, I wouldn't write one, but I'd write a payment proxy for steam or something like that.

I am interested in the work on "real games" and do work on something but I don't see it as something related to this. and it is far from being done. It will include a bitcoin payment possibility if I'll ever accept payments.


and about my future bitcoin "gambling work"

my infrastructure is sound now, I'm happy with it. I can easily support multiplayer for example. there are few more little things to fix, and then I'll make new things.
I have an idea for a lottery, it should be interesting, this, I'll do quickly, I'd just like a lottery like the one I have in mind to exist.

and then I'll work on my first "real" thing. I won't go into details yet.
it will be different from the others and it won't be a gambling game but it will heavily revolve around bitcoins.

I'll be able to work on this in about 6 days, as I'm traveling atm. and you can expect that simple lottery beta in ~10 days.

you seem to have some preferences or something in mind, I'd be happy to hear about it.

No preference at all.

the server died yesterday, restarted it, will investigate.

- edit -

fixed

deleted post :)

multiple payments to the same receiving address are now supported, lack of this feature annoyed few people :)

Referral rewarding has been implemented!

for every user you refer to the site, you'll forever receive 5% of that users losses.
check out the referrals tab.

Now I know why I don't gamble, I was up (Let's see how far I can take this!)

And then I wasn't.

yeah. gambling is so very nasty :D and statistically, you shouldn't do it at all.
I also lost some btc myself, on a similar game, and then I wrote this one :)

I've been observing the strategies people have, and they mostly don't ever stop. their balance fluctuates until they hit the floor.

Yeah, the house always wins eventually. The best strategies won't do any good if you don't have enough BTC to ride out the rough patches, and reaching for an even higher payout prevents many people from cashing out when they are riding high.

What killed me was the wait, almost instant money in...."Well I have to wait a bit to pull the winnings out so why don't I just play some more...~Some time later~ that did not go as planned."

Thats what happen to me. But at the end, i was down half of my deposit and just bet it and won. So HA@!

I've enlarged referal reward from 5% to 10% and gave additional 5% to all existing users for their past referals.

cash out! :)

I have withdrawn to a MtGox account and it says the withdrawal is confirmed(it said so instantly), and blockexplorer shows an empty transaction...

I'm hoping it's just cause MtGox can take a while. Please help me, owner!

don't panic :)
the site doesn't wait for confirmations on its own payments, it just calls them confirmed by default. and the blockexplorer needs a few minutes to notice them, they are showing up now, everything is fine.

Yes. It is solved.

I was not aware it took a while.

Thanks!

+1

Waiting for confirmations is devilish idea how it should work ;D

I'm strong, I can keep from playing, I can keep from playing, I can keep from playing... ;D

Only won like 0.0022 on my 0.05... BTW, going for automated pay outs if one loses account?

Keep an eye out this weekend for the world first bitcoin game for android smartphones. holorga was nice enough to provide an interface for his game for me to work with. I am hoping to have the initial(and most likely final) release available for tomorrow.

It's time to load up your bitcoins for bitcoin gaming on-the-run!

I  love the Bitcoin Minefield! I was scared to take a risk, so I only bet small amounts and cashed out when I could. Still turned up a profit.
I'm really excited about the Android game!
Anyways,
http://imageshack.us/photo/my-images/143/screenshot20110902at112.png

I've decided to put some images together as an idea of what to expect for bitcoin minefield for android. Everything is implemented and fully functional as far as gameplay and logins go. I've weeded out as many bugs as I could find on my end as to not have to release anymore than 1 single candidate.

I am still waiting on a few minor changes to the server-side code, so while I'm waiting, I will take suggestions from people if there are any.

My own personal login keys are used in these two main screens, but to give you an idea of what it looks like I have only blurred half of the string.

Startup of the game activity:

Here is the mine count selection screen (press menu button on your phone to access it), as you can see, the same min/max limits are present:

Here's a little bit of gameplay. 3 blocks in a row, lucky me:

A little more gameplay where I'm not so lucky:

And finally, the epic moment that was screencapped out of utter and complete luck in one attempt(take a look at the mine count at the bottom right:
http://img6.imageshack.us/img6/1295/game5.png

There you are. feedback is much appreciated, especially considering I only plan on one release.

EDIT: I should also mention that as you can see, there are none of the proof values displayed in the android version. I felt that it may clutter the screen up too much and I wanted to keep this game away from the bulky side of things. If there is any concern, you can just as easily see proof by logging into your minefield account via your favorite web browser simultaneously. Any action taken place via android will automatically sync with the web-browser. ie: click a tile in the android version, your web browser will also automatically reveal that tile.

Hey there SmokeAndMirrors,

your game looks nice! But there is one thing, many game developers forget: color blindness!

I myself suffer from a minor color blindness and even though I can make out the difference between the bomb ond non-bomb fields, it isn't that clear on the first look.

So since there are many people out there with the same problem you should consider changing your fields color or insert a little bomb image or whatever.

Here (http://www.destructoid.com/ramblings-of-a-colorblind-gamer-72229.phtml) is a little article about color blindness and computer games, that show that even big game corporations make the mistake and need to be aware of this problem!
So don't loose potential customers, just because of this ;)

That's a really good point. I hadn't even thought of that, though I've only done so much game dev.

I had actually been planning on adding a little bitcoin image to the correct blocks, and some negative image to negative blocks. I'll be sure to add these before the release.

For me green and orange next to each other are bit hard to differ and some people must have it worse.

One extra suggestion, differ the chosen onces too? So player can see which ones he has "won".

So, what happens to those odd hundredts of cents in the end?

Casus: I played a bit, lost some and had a really weird amount left; something like "0.0062". Added some new funds to make it a round number (and being able to play a bit more).
Then lost interest. With 0.0025 left in balance.

That amount is not enough to transfer without fees (according to the official client anyway) and probably not even worth the effort.

Will you keep that amount there, for when I come back to deposit some more? And what if I come back in two months? Is there a moment after which you close the account and take the balance as your own?

I made a bet, and in the middle of playing - the game refreshed on me and i lost my bet (without clicking on anything).

whoa, I've missed last ~10 messages, for some reason I stopped receiving emails on topic posts.
I see that Smokeandmirrors posted some images of the android game. great.


we've resolved this over pm's, it seems that his browser (chrome) had some trouble with occasional auto refreshing of the page. let me know if any of you encounter a similar problem.




good question: nothing, I let you cash this out if you wish and I'll loose money on transaction fees. I hope nobody will abuse this as there is nothing to gain from it.
and that amount will be kept there for you forever in your account.

someone just won 16 btc, congrats :)

That's it, I'm addicted. I swear, I'm just going to buy 10 BTC and put it all on this one game. It's not even about the BTC, because to me more BTC means more playing until I lose. It's just fun. You never know when you'll hit a mine, and it's a lot more "realistic" than the normal minefield.

Maybe some of the profits could be donated to a charity that provides assistance to victims of minefields.

Like BurntSnow?

hey, yeah, I increased the rake in order to support upping the referral earnings from 5 to 10%, as I got bunch of requests for that, I was forced to do that in order to prevent a person with two accounts from exploiting the game.

burntsnow? googling didn't help me :)

- edit

oh, haha.

a good strategy to cheat might be to start a minefield charity and then play this game.

someone went in with 1 btc on max mines and won 22 with first bet ;D
it was so clean I initially thought it was a hack, but everything checks out.

Possibly the "International Campaign to Ban Landmines (ICBL)"
http://www.icbl.org

I just sent them a message to ask if they accept donations in bitcoin.

even though the relation is cute because the game is called bitcoin minefield, If I'll send the profits to charity I would like to choose the cause myself.

which I didn't say I will. and you are obliviously pushing me, which I find is not very nice.
I'd much more appreciate something along the lines "hey, you can give the profits to charity, here is how"
then contacting random organisations almost in my behalf without my feedback.

that said, I'll hardcode sending of percentage of the profits to the mines related charity if we can find a way to do it because I like the idea :) I'd much more prefer the demining organisation though, then the lobbying one, if I'm not making a mistake with my quick glance at the site.

in case you are not just trolling, for the next time, maybe try a gentler approach because my reaction towards you is still negative, but its not negative towards the idea so thanks for that :)

also, be aware that the profits from the game are not high.

I'm looking at the bitcoin100 topic. looks good!
I'll send 5 btc and give you the blockexplorer link, and will automatically send 20% of the profits to minefields related charity if we figure that out.

now ill waste even more time and btc for the cause :)

if you start a minefield charity of your own the game will be unbalanced towards you. maybe a strategy to ponder?

Sorry about that and the decision does rest with you and you are entirely welcome (and encouraged) to run the game for profit but you might get even more interest and thus more profit if a percentage goes to a well chosen and worth-while charity.

I've tried the game, nice little game :-)
But since I'm not yet seriously mining and don't want to buy bitcoins for real money (yet) I only spend 0.04 BTC and now I have 0.005 BTC left in my account.
Since you said you would loose money on the very low transactions, is there a way the cancel my account and donate this 0.005 BTC to you?
Maybe I'll play the game another time in the far future, but I really doubt I would still have my secret url to access my account.

feel free to send it to yourself, I don't mind. by abusing I was thinking of sending a lot of small transactions for no reason. and if you want to leave it, just ignore it. the btcs are in the system and they are residing in the same pot :)

great game!

why down?

fixed it.

Great game you have here. Seems pretty balanced in my opinion.

Good work!

thanks, when I got into bitcoin I didn't know what to do with my coins :) and the games I've seen I didn't like so I tried to do it better then what was around at that time. I will get into it again soon I hope and make something new.

and its balanced by a simple equation. games like this are not hard to 'balance'

i sent some bitcoin to my account on the website (only .01 to give it a try) and its been comfirmed by the bitcoin network but it doesnt say i have it in my balance.

damn, sorry,
I had two other reports like this in the last few days. please provide me with your info via pm or contact@bitcoinlab.org and I'll fix it.

I don't really understand the payout scheme. If I bet 1 BTC and click one field (playing with 10 mines), can I really cash out 1.54 BTC? It says "10 mines, win amount x1.54" at the bottom. What is that "amount"?

Yes.
If the field has 10 mines and 15 free fields you have a chance of 15/25 to win x1.54 so on average you get 15/25 x 1.54 = 0,924 BTC for 1 BTC.

Firefox can't establish a connection to the server at minefield.bitcoinlab.org.

It's down again.

You changed from SHA256 to MD5.

Your Trust string looks like this:

md5("[[1,0,0,0,1],[0,1,0,1,1],[1,0,1,1,0],[0,1,0,0,0],[0,0,1,0,0]] 6194c0e2ffb667fa41385e16d9fb010b")

Due to weaknesses in MD5, it is entirely possible to fudge the array (on the left) and quickly compliment the arbitrary string (on the right) to generate a colliding MD5.

If you are going to continue using MD5, I recommend replacing the long arbitrary string with a sequence of 3 common dictionary words that maintains a strong entropy but makes colliding MD5 values nay impossible.

My wallet literally sent you its contents by itself and games started rapidly playing until my wallet on the site emptied. Anny chance of looking into what happened there? It looks like my wallet was stolen and sent to you, but I don't see what possible benefit that could have for whomever did it. That was kind of my paycheck for this month that I just got today. I have to wait another month to get groceries unless this gets solved.

are you serious?

I smell bullshit...

wow you are right, I wasn't aware that attacks on md5 progressed so much. the last time I was hearing about it is by those guys that created a rouge certificate authority. they had a cluster of 200 playstations and two days.

thanks.

Completely serious. I sent .01 as a test to see if it was working and the whole thing emptied. Is there a way to find out what happened or even who did it? I can make up the lost Bitcoins in an odd job or something, so I don't care if I ever see those again. I just want the thief punished.

Ok, I've called mr Poirot. If anyone, he'll find your thief.

I lol'ed.

Not sure if that was sarcastic or not.

Anyway, I've decided to just give up on ever finding them. Shame it had to start like this, but at least it wasn't that much. I got a small job from another site and if it works out I'll have enough to replace my paycheck. Things seemed to work out, which is good.

I don't blame any of you for not trusting me. You had no reason to and, in the online world, that's how it works. I hope this game is successful. I played it a few times since then on the free section. It looks good. I'll try again when I raise enough spare Bitcoins.

Help me to withdraw funds
I have not confirmed a payment from 13 11.3.2012, 6:54:20
may by you can kill it ?

not sure what you are talking about, I've sent you a pm

check and delete plz transactions to  1GWQyaeZgcANhPmexNtx3s6uhUqKnQnZw8
it have 0 confirm

oh, I see the problem, fixed. sorry about that.

Finally got to play. Lost, but I still had fun and it's pretty cool how you can adjust the odds.

I am trying to use this, but cant click anything :(

No buttons work & how do I set the bet? I am using chrome via a mobile phone tether.

this is a problem on your side, it might be a strange browser plugin that is doing this (try firefox?)
or, more probably, the problem is your tethering, it might be that your mobile provider is blocking websockets.

I can't drag & drop wordpress widgets either - same issue? It normally works in IE, but I hate IE & firefox is open to adware :(

So...what ended up happening with that whole 'Android app' thing? I was kind of looking forward to it.

I don't think that's happening unfortunately.
the guy working on it almost finished it and gave up :)

That's a shame. I wish I could take over for him, but I know nothing about programming! Haha :P.

just recently I was too 'hey, that android thing, whatsup with that?' so I messaged him :)

Are you still running the site at all? I made a deposit and it just switched to a 403 error.

403? are you using the proxy or something? you should never get 403s from my service. yeah, its running and should be fine, lemme know if you are still having trouble.

For me the site is working.

I would recommend just using a different hashing function.  Since the left side is of known structure, just differences between 1s and 0s, one could easily start a game with 24 mines, giving only 25 possible forms for the left side.  Then, it's just a three word dictionary attack... if you pull from too small of a pool of words then coming up with a rainbow table becomes relatively easy.  Someone could setup a bot to run you dry, irreversibly in a matter of minutes after the rainbow table was created.  Go with a different hash function.

The first line of the quote states that you went from SHA 256 to MD5.  Why?

I think you forget the 128 bits of the last part "6194c0e2ffb667fa41385e16d9fb010b"

Site is still up, I won 8 btc there recently :)

In the post that I quoted, it points out that due to weakness in MD5 you can find a valid string for that and still come up with a valid MD5 for an arbitrary left portion.  Their solution was to use dictionary words, but I was pointing out that a rainbow table renders that approach susceptible to cheating.  The random 128 bits is secure but doesn't prove that the site isn't cheating (I trust that it isn't, but it still doesn't prove it); the dictionary approach does not guarantee that the user won't cheat.  The easiest solution is to just use a stronger hashing algorithm.  Then any arbitrary string is sufficient to demonstrate that the site isn't cheating, since SHA 256 has (as far as I know) never produced a hash collision.

Site has error 503.
I played on it before, but on free-play mode.
Can't wait to play for real.

ooops sorry, gimme a few mins

ok, fixed

Thanks for fixing it.
That was so fast! And this is a cool game.

thanks, and good luck! :)

Suggestions:
Stats feature (total won, total lost, etc.)
Backup your URL to a flash drive directly from the site.
Let the user select a field size.
---
I hope this helped.

yup, those are all good suggestions, thank you.
I will probably start working on a few new services in a few months. I think I won't work on new features for this one much.

let me just acknowledge this. you people are totally right.
I will take time in the near future to switch back to SHA256, I won't risk it with dictionary words and such, as just using a proper hashing function is easy.

I did use SHA256 before. but after a system upgrade the library I was using broke, and I quickly just switched to MD5 to get it to work and left it at that.

the site will be back on SHA256 within the week.


btw,

site is currently down, bitcoind went crazy, I'm repolling the block chain.

The site is 503 again.
I got my BTC ready to bet.
Thank you for your service to the bitcoin community.

I know, it will stay offline for a few hours, bitcoind went crazy and is downloading a whole blockchain now.
I'm sorry you've hit 503 twice, the uptime is usually pretty good.


btw, you've had some good suggestions for the site, let me know if there is a service you'd like to see in the future, I will be working on new things soon and am slightly out of the loop with services that are available atm. I will do a websocket multiplayer game for sure.

OK.

By the way, do you use your own server or do you use a VPS?

its a cheap VPS, its too weak for bitcoind which is extremely resource intensive lately.
when I start working on new stuff I'll revise the infrastructure. which will include renting a dedicated machine and isolating services

It came online for a few minutes. Now 503 again.
It's OK with me as long as the site works when I play for real.

I know, working on it.

ok, site is back up, it took more then 24 hours to resync with the blockchain, bitcoind went crazy due to too many addresses being generated, needed to recreate the wallet.

What is the bitcoinadress? Both adresses top left and bottom dont work for me.

Click on the Balance button (top) for deposits and withdrawals.

Thanks. It works.


So now ... If I come from
'bitvisitor' I don't want to play in a frame. So
i need a link to go to 'http://minefield.bitcoinlab.org'
I have found the link only here in this forum.

I see ...
It's not a fair play.
This is a delusion a fake, i mean not fair. You take 100% of the stake. But you pay only 0, 02 to 0, xx profit. And you dont say it.
Example:
I play 3 mines at stake is 0.01 btc.
I win 5 times 1.02 per cent. Ok  you mean: 2% x 0,01.  For me 5 x 0.0002 btc= 0.001
First the profits are 0.001 btc. So i had to win 50 times to win 100%.

Now I lose. And you take 0.01 btc = 100%!
Where do you write this naughty game rules?

I have need 0,03 btc to understand your trick, because i don't believe this.

yes, it's not a 'fair' play in the sense that the amount you'll receive is slightly lower (~10% in this case) then chances of you winning. but this is a fact for all gambling.

if you played with 24 mines, you would have to win only 0.045 times to double your bitcoin.
if you play lottery, you have to win only 0.0000001 (whatever) times to double your money,

that doesn't make lottery or 24 mines scenario any more fair. you have to take your chances of winning into account.

I'll take some time to explain it to you a bit later. maybe.

If you want to, we could work together and I could make you some new tiles..

yup, pmed

switched to sha256 as requested, partially applied the new designs

This is my favourite gambling website, so cool! :D

thank you:)


btw, I've lowered the minimum bet.. people seem to be interested in that. I'll pby lose bitcoin in the long run on transaction fees but, nvm.

I certainly am thanks :)

The missus and I always like to grind away for hours on minimum bets, lots of fun.

I love Minefield game

When will my tiles be up  ;D

503 again！
A very easy and straight forward bitcoin gambling game! just what i need!
easy, casual, and lots of fun!

when will the site be back again?

I don't like gambling games.
I thought it would be more like minefield on windows.
Where you can puzzle out where the mines are.
I'd love to see skill-based games with the money inside the gameplay.
Like command&conquer with bitcoins. 
each unit you buy/kill is real money and it's player vs player money.  The "house" doesn't earn much but it will be more successful then yet another gambling game.

I agree with you on that one, I'd like to see skill based games too, I'll have time to work on something like this really soon.. not sure about success, but I'd like to see such a thing.



site is up btw, sorry, I was not around and something exploded and automated checks failed to restart the service.. its running now.

good fun!

Will

hey, server is down again, its obviously too weak for bitcoind..
I've ordered a new, powerful dedicated server, I'll set it up tomorrow.

You could use http://blockchain.info/json_rpc_api

hm, how do you think I communicate with bitcoind now?
yeah, this api is the standard way to talk to the standard client.

What do you mean? You comunicate with bitcoind with JSON RPC on your server, right?
If you comunicate with JSON RPC on your server, then you could use Blockchain.info JSON RPC API to manage transactions (Send, Receive, etc) without having to run by yourself bitcoind...

oh, sorry, thought that you linked standard JSON RPC bitcoind api to me..  oh, I see, that's interesting.. not sure if I'm ready to trust third party website with my wallet, taking the history of bitcoin websites into consideration, but this is really good to know, thanks. the service looks really well made.

blockchain is being synced on the new server, the service will be up in a few hours.

No fun at all while the server is down :(

ok, its up again, should be much faster and stable now, switched to a significantly stronger machine.

When will my game tiles be up (I want to see them in action!)

oh, sorry, will pm you, I was busy these days

I love this thing. It's fun and really heavy on my wallet.

Made it to 2 BTC with 0.5 deposit then lost it all.  :-[

I cannot withdrawal. First time this happens.
"Error: Insufficient funds"

Balance: 0.2669 BTC

Sent user id by PM.

hey, you'll be able to cash out your account now, I had a super lucky high roller that cashed out everything from the servers wallet:)

how much did they win?

100+ btc at one point, they cashed out around 50 and played 24 mines until they lost the rest.

the service is down atm.
I need to access my mtgox to transfer more bitcoin to the server, however, I've lost my yubikey together with my home keys yesterday :) I've started the process of getting access to my mtgox account again.

ppl sorry, still here, still waiting for mtgox. last reply from them was 3 days ago, I delivered what they asked for within 30 minutes of their reply.

We should make a "buried treasure" that only shows up 1/10000000000000000th of a time but automatically clears all the blocks for you  ;)

the site is up again!

I don't think that changes things. I want to leave it simple. this would be an equivalent of enlarging the minefield + playing on max mines.

this game is great. i love it! its fun and also made very simple with state of the art technology.
keep up the great work. btw: use some own textures or buy something. if you take 3 usd you get many very good graphics on graphicriver.net

some kind of weirdness with the server, I'm guessing due to bitcoind being moved to another machine, I've turned the service off until I figure this out. won't be able to deal with this in the next 24 hours though.

any plans for ltc minefeild

That could be really cool! ;D

Hi, I cant even play this game properly as I have to keep refreshing for the game to be responsive! Any issues?

hm, refreshing? strange.. the site is working properly for me.. maybe try changing the browser? ff and chrome work for sure.

Well, I just tried IE9 and Opera works better than that! I will continue testing.....

OK, IE9 and Opera don't work though Chrome is running smoothly :) Little annoying but it will do!

ie is not supported, I should add a warning message for IE, and I'll figure out opera.. I should be able to get opera to work.

Sometimes I think that TNT is following my mouse cursor :)

Also, why not have a permanent deposit address associated with a user id?

yeah, good question, when I was making the site I was new to bitcoin and supposed that people care about anonimity a lot so I implemented this thing with rotating addresses, you can actually use a single address for all the transactios.. I should make this clear.

not really, not sure how big ltc is, should look into it at some point. I'll consider it for the next game I make.

It's very easy to adapt the Bitcoin Minefield to Litecoin Minefield, instead of bitcoind you use litecoind, and the JSON RPC is the same  ;)

https://en.bitcoin.it/wiki/Litecoin

yup I supposed so, I'd need to create some logic/gui for it. maybe just running ltc.minefield.bitcoinlab.org would be easier.

My experience with minefield is that no matter how much you win, you are going to loose it all eventually if you keep playing!

yup, you could have calculated that from the odds too.. this is true for all gambling.

Bleh. I thought I found an exploit when playing with 0 bet. I had a win/lose ratio of 10/3. Then I made a deposit and lost everything (wtf?) ;D and when I had lost all hope I thought what the heck I'll just put the rest to btcdice and made a bet directly from minefield. God I feel like a retard..  ::)

lol, if you feel like sharing, what kind of exploit? I'm curious.. and I hope you won at btcdice! lol but I don't think you did

I set it to 24 mines (only 1 out of 25 wins) and clicked a random box to see which was the winner box. Then I clicked on the same box to play again (not the bet button) and kept on clicking the box that would have won the last time. For some reason the minefield seemed to choose the same box for win in the next 8-18 turns. Not always, but often enough that I figured it would be profitable because when you win it's 22.5x the bet.

When I made a deposit I noticed that I could no longer do this. I had to choose the bet ever round instead of just clicking the TNT i blew. This seemed to change the odds for the same box to win again (again I'm not sure about it). But I tried to play this strategy anyway, and I had luck for some time. I won about 7 times losing only 3 rounds and was up from 1BTC to 1,159BTC (0.001 bet). Then I started taking more risk and also losing more. It was totally frustrating when I swapped to the 0.01 bet and it took over 40 rounds for the same box to win. Sometimes when my box lost over 25 rounds in a row i switched it to some other box just to see earlier choise win. daaaam :P

And I sent my last cents from minefield withdraw to dice so even if I did win the dice I wouldn't have gotten a cent out of it :D

oh, a minefield generation algo doesn't have any information about the previous minefield when generating a new one, it was a coincidence :D

I think I'm having problems with referrals being counted.

I'm pretty sure that its working fine.
if you click on a referal url multiple times, it won't count as another user being refered, clear the cookies on a browser you are clicking with inbetween clicks

Hey... are you ever going to use those tiles i made you










 ;)

Post here the tiles, I want to see them! ;)

P.S: I still like the MineTiles...

https://dl.dropbox.com/u/36814103/grapesandwich.png

https://dl.dropbox.com/u/36814103/btcminefeildholder.png
they go in this frame

hey, pmed

hey,
yeah, you are having some kind of problem,  the site can't connect websockets to the server, your network is probably not allowing connections on all the ports to remote services..

you should have buttons to chose the bet above the minefield.

I am officially addicted

For some reason no matter what withdraw address I put it just saying invalid address. Please help me its kinda annoying I just want to pull the little bit I put in back out.

Are you sure there is no enter or space character added at the end?

It finally worked but the transaction still hasnt shown up in my wallet and its been about an hour since then. Meh

are both of you the same person? you sound similar :)

you are the first ones reporting this, please send me any info I can use to locate your users and resolve this. like transaction id or your username.

Am having a hard time even locating my account on it however the transactions would of come from the following wallet or wallets. And I do recall cashing out on one but never got the payment or it was lost in transit or I spent up on all of them. Its been awhile and cant find any my user details but here the btc addresses used.

1PE7igeVTTtZfTmUTmG2hHz5RSBGNrtfFr
14yr6utPZr62uvxDnZ3bPnLw3rPhsLEFic

I do not log from which addresses the transactions came, as the data is commonly not trivial, afaik not exposed by bitcoind, and I don't have any use for it.
I could look over recent transactions by hand if you were to give me this info right away, but this was 5 months ago.

in order to locate your user I need more information, like, transactionid, your username, addresses you sent bitcoin to, your exact balance, anything more.

The only one i can find as the other now says no transactions on it..

26.12.2012, 1:56:54   1JRCt9CkF2fGAuZQK7ydfU75dD5yNfJvTy   +   0.03   confirmed

this is an incoming transaction, not an outgoing one. and it was received properly, you played the game and you lost everything. there were no outgoing transactions.

and about the other one, its very improbable for the transaction to dissapear from a transacrion list if it was displayed at any point.
this data never gets deleted, and it gets sent to a client once its in the database. so I'm guessing that you have a wrong account.

I can't help you if you can't show a problem to me. and I'm repeating, I'd have a chance of somehow finding your user if you didn't wait for 5 months.

Forget it then. Cant find any other details as i do not have them so its lost in an dormant account somewhere. Wasnt much anyway so nothing gain little loss to the house but guess that's the way it goes sometimes. Thx anyway :)

noticed some weirdness, the service is offline while I investigate

ok, everything is fine

someone is trying to hack the service, which is nothing new, but I've seen some weirdness so I'm making sure that everything is fine, the service will go online shortly.. in any case, users shouldn't be worried, most of the balance is in the offline wallet and your bitcoin is safe.

I'm just being paranoid :)

I think it's pretty ridiculous that I can play for 0 bitcoins and 10 mines and am able to click about 6-7 squares until finally hitting a mine. Yet, when I play for actual bitcoins with 3 mines, I typically hit a mine within the first one or two clicks. I'm having a really hard time believing it's 100% random. I've tested this with at least 10 games of 0 play and 10 games of bitcoin play.

its actually pretty simple to verify. just click the hash at the bottom of the screen when your game is over. you'll get something like this


thn just veryify the hash using ANY SHA256 calculator, like this one:
http://www.xorbin.com/tools/sha256-hash-calculator (http://www.xorbin.com/tools/sha256-hash-calculator)

I LOVE provably fair games. lets me sleep well at night  ;)

EDIT: I should have mentioned that the HASH you are verifying is given to you BEFORE you start playing the game (right after you select your wager).

thanks nyusternie..

yup, the game is provably fair, which also lets me sleep well as I don't have to lead vey long conversations about cheating.
rickylford, I have a feeling that my luck is the same, and I'd have the same worries :)

let me explain it in detail for people that don't know what hashes are, and I'll use this for faq later..

hashing generates that long random looking string (called hash) from any data. its like a signature for the data, any change in the original data would completely change the hash. its commonly used for data validation, for example application installers tend to check the hash of the thing they'll install, verifying that the data isn't somehow corrupted. communication protocols do this, and applications with any-cheat or piracy protections..

a hash (sha256 is the type of hash I use here) looks like this: 29acdf9aaed991265c97e5b9e2a5d699b66194bced0f87aa3cfeb14200532072
also, hashing is a one way function – you cannot get the original data back from a hash. (which is obvious, you can't store a lot of data in a little of data. if you could, you could hash everything on your disk and just keep this one hash instead of all the data)

you can play around with hashing to get the feeling for it on one of the online hash calculators http://www.xorbin.com/tools/sha256-hash-calculator

so, how does the game prove that it isn't cheating?
you are given a hash before you start playing, after the end of a game, if you click on that hash, the server displays the original string that got hashed, which is a text based field representation and a small random string, which proves that the server has generated a fixed field before you started playing, and its not deciding on positions of mines after each click.

the string looks something like this:

[[0,0,1,0,0],[1,1,0,0,1],[1,0,0,1,0],[1,0,0,0,1],[0,0,0,1,1]] jsmrHbNZR0SWT7BH

(you can now use any hash calculator to verify that a hash of this string is really the one that the server displays)

this small random string at the end (jsmrHbNZR0SWT7BH) needs to be as there are around 30 million possible minefield combinations, and a player could generate hashes for all possible combinations and find out the current mine configuration by matching the hash a game displayed.

hey, server was out of founds during the last hour, sorry about this, founds are on their way and you'll be able to withdraw soon.

ok, founds are in

Just a friendly tip: It's funds :)

You may want to order the transaction history query.
It's showing the Jan transactions in the bottom and Feb transactions in the top ;)

BTW, can you create a page like Bitcoin-Kamikaze (http://bitcoin-kamikaze.com/?father=101696) has, where you show referrals stats?

Something like this:
https://i.imgur.com/L7vBlQk.png

thanks for the feedback, I'm planning a rewrite soon (will move payment processing to blockchain.info to offer instant payouts) and I'll include more details about referals..

haha thanks

I keep getting "invalid address" when I'm trying to withdraw. I tried with several addresses. I'm 100% sure these are working addresses. What's the matter there?

strange, can you give me your username and an address you are trying to use?

hold on, it might be because I lack 4 confirmations on my deposit? just noticed that note

edit: thank you for your quick reaction though, gives me a lot more confidence in your service :)

don't worry your btc is safe :)

it still shouldn't tell you that the address is invalid, I've updated a code a bit, try it now. (reload page)

and I've changed the confirmation requirement to 2, so you'll be able to cash out sooner.

I sent 0.025 BTC to an address that was generated for me (you can see here:  1EY6boTD4jCY9CNdfP4i8BMioF1m4NYJ7b)  but it never went through, it wasn't every added to my account...

What should I do?

you are right, I'm not sure what happened, sorry about that.
the transaction wasn't registered by the system.. I've credited your account manually and I'll investigate.

Thank you.

Hello,

I would like to report a possible security hole in the current scheme of things.

The idea to use only 'url with secret' for logging in is neat but not entirely safe because the web server uses plain http with no encryption.

Let's say you open the site for the first time and it gives you secret like http://minefield.bitcoinlab.org/?secret=fngrOdO23tDOTuPW
Then you deposit some btc.
If someone is sniffing the traffic it is fairly easy to extract the GET /?secret=fngrOdO23tDOTuPW string from the HTTP request. Then he needs simply to open the site with that secret and he can withdraw the btc to address of his choice.

I can mention two solutions.

1/ get a https certificate and the run the website over ssl/tls. This will resolve the sniffing problem since all traffic would be encrypted.

2/ Make withdraw only possible to addresses from which deposits were received. But on second thought this is not very secure either. A hacker could break into your account, deposit minimal amount of btc and after the deposit is confirmed (and the sending address accepted as viable for withdraw) the hacker request the whole amount to his address.

Best~

hey, yeah I'm aware of this, I do know what https is and what it is for :)
I don't think that this is very important, but I do plan to switch to https soon.

and on why I don't think its important:
the number of local networks being sniffed by attackers interested in bitcoin is super small, people that know what https and sniffing is, will make sure that they have a secure connection if they care to, and people that don't, will probably get owned anyway. so I'm maybe saving one person in a few millions, and this website didn't receive that much GET requests yet. and statistically, I'm saving them around 0.05 bitcoin...
but still, yes, https, soon.

PS
I may sound too dismissive, that's not the idea, thanks for reporting :)

Sorry, I didn't mean to offend you. I have no doubt you know all that, but since the post will probably be read by other people, I wrote it in a more detailed manner, so they could know what we are talking about :)

i dont understand how i lost 3 - 4 btc playing this.....
waste of btc.

 ;D ;D ;D ;D ;D ;D ;D

I'm really interested to see more details from my referrals  ;)

yeah yeah will implement it :) I'm finishing another project these days, in a month or two I'll be able to get back to this..

I deposited 1 bitcoin but it's not showing up :(

user-5125f42adf7b95cc10034bba

just so this isn't a last message in a thread, we've resolved this :)

service is offline atm,
my bitcoind is stuck at a block 225459 so transactions after that block didn't get registered.


An upgrade should fix it, I'm running a really old (debian package) version.


the site will be online in a few hours.

ok, back online, let me know if your transaction didn't get registered and I'll credit your account manually.

oh, in case you've won something but can't cash out due to 'not enough funds' error, please wait 30ish minutes, funds have been sent to this new wallet, the transaction just needs to be confirmed.

My latest transaction has been unconfirmed since 27.02.13

If it cant be fixed, can you remove it?

My username is: HotHubHD

How much have people actually won from this>

Because strangly I just happen to click on 1 square and lose most of the time, when there are as low as 5 mines...

Also, its funny how I almost never hit a mine when i choose 0 btc, but the second i actually pay something, I instantly lose it.

Im calling shinanigans.

Wow I am not one for these kinda BTC gambling things, but this looks neat, will have to give it a shot!!

erm...op, i see you online daily but you dont answer my PMs or messages?

I lost my secret link because i had to re-install windows.
I can give you my username and verify that the link is mine, i got over 100 referals on it and it is growing daily.

Could I please get that account back?

Is the OP still maintaining this?

Still really like it, will try some micro coins with the 24 mine setting soon ;)

Liam

Hello, I deposited 0.013 BTC in the address for my account (user-314159265358979323846264), But it's not showing up.

It currently has 156 confirmations on the blockchain, just wondering if you could help out :)

You would probably be better PM'ing the OP :)

Liam

Yeah, thanks, holorga hasn't been active for 7 days, I'm thinking of sending an email instead :)

Wise :) I wonder what happened to him...

Hope he hasn't left this unattended - not the best thing to do!

Yeah, I hope he comes back soon, there have been a few people needing support lately.
He's probably away been away from a computer/electricity/internet for a while, or he's just taking a break :)

Lets just hope it isn't anything sinister ;)

has anyone been able to cash out any bitcoin from this one today  ???

I was able to cash out yesterday, it's possible that the payout account is empty now, as the OP seems to have been gone for about a week.

my account was hacked and lost 0.0012 btc.

I dont know who done it but all i have is their waller address?

I dont understand how they done it, seeing how no one else is meant to see my link.

Well, if someone was actually trying to steal from your Bitcoin Minefield account, it would not be too difficult.

It was assumed to be too unlikely that someone would try to steal from it. (As was mentioned before in this thread, there is no real security, just the secret key which is sent to the server unencrypted)

How many confirmations should it take until it adds to the balance reflected on the minefield page? The first transaction I did was almost instant, my second deposit is taking much longer, is this normal?

Thanks :)

https://blockchain.info/tx/61a3df994a050c6c8fd7e938bd14c78c305accc077e17f5950d68d117fa80910

Oh, I guess I should post my user and amount I'm missing. user-5169a2b2520646bd7d0970bf missing 0.005 from the above transaction.
Thanks!

Don't touch the slider grabber, touch the 'rails' of where you want it to be and it should work.

oh, damn, sorry people, for some reason I stopped receiving notifications for this thread so I missed the last 10ish posts. I'll read and reply to everything later today.
I have been replying to support emails. Your BTC are safe. I'll contact everyone that mentioned a problem and will make sure that everything is ok.

you are spreading disinformation and fear.
it is not unlikely that someone would try to steal from this site, a LOT of people try to steal bitcoin, everywhere.

a person that's in position to log in as you has to be in the same local network and with access to your traffic.
that same person is in position then to steal your facebook and gmail sessions too (login is encrypted but cookies are sent over plaintext connection afterwards)
do those sites offer no real security too?

I apologise, that was not my intent when I wrote the post.

I was referring to the fact that it would be relatively unlikely that someone would hack into your local network with the specific intent of gaining access to your bitcoin minefield account, although of course it is possible, especially with bitcoin exposure rising.

I said that it would not be too difficult for someone to gain access to your account if they were specifically trying to. If this was unclear I mean that if someone knew enough information about you, and had the knowledge to gain access to your private network (or was able to sniff packets some other way) they could get into your minefield account with relative ease (as the page isn't currently secured with ssl).

When you access a site through https (default on facebook, etc), all data except for the host you are requesting is encrypted. This means that all your cookies and other information is encrypted, making it difficult for someone sniffing on your network to gain access to your accounts. It is still possible for someone to gain access to these accounts through exploits such as MITM attacks, etc., but these usually take more effort, network access and knowledge than just sniffing packets.

If you think that network sniffing is a significant security concern, I encourage you to use https (if it would not be too much of a hassle) as it would encrypt the path of your site and the cookies sent, protecting the user's secret id from being found as easily.

site dead?

"the service is temporarily down
this is probably due to maintenance."

Wow.. you are quite the big man aren't you?  Go troll else where.

This is a forum. Everyone here is a troll.

Especially when you have a sock puppet for an avatar too.

That was back when someone accused a lot of people of being sock puppet accounts and someone posted a bunch of sock puppet avatars. Test.

hey, yeah, the site is down atm, will go back online later today.

Hi!

I deposited 0.54 BTC today, got 9 confirmation, but my balance didn't change, still 0. Could u check it?

Thx

I have 9 confirmations as well nothing in my account though pm was sent. please check ajw7989

hey, bitcoin daemon on the server got too old, I'm upgrading it,
it will take time to sync with the blockchain, but your btc is safe, the service will be online in a few hours, sorry about this.

I thought this site was down for good.  Fun, simple gambling game but the house edge seems rather high.

thanks, it was a experiment from a year ago, it was supposed to just be a coin flip, then I made it iterative, and then I made the odds variable and ended up with this. I know that the house edge is not very nice.. I need to pay referal rewards.. and I'm happy with the number of users though so I'll leave it like this, and I'm working on other projects (http://bomberman.bitcoinlab.org/ (http://bomberman.bitcoinlab.org/)) right now.

Just punched my email in to the new project.  When do you think it will fully launch?  I'm interested as an advertiser, not a player.

the game is playable already but not sure when I'll launch, I'm kinda relaxed with the development, in the next month or two.

excellent game, best ever !

haha thank you

Introducing the Minefield app for Hive (https://bitcointalk.org/index.php?topic=304060.0;all).

Please note: as with Hive itself (https://bitcointalk.org/index.php?topic=304060.0;all), this should be handled with great care and at the moment we do not recommend it for any kind of day-to-day use.

The latest releases will be made available here:
https://github.com/hivewallet/hiveapp-minefield/issues

Issues can be tracked here:
https://github.com/hivewallet/hiveapp-minefield/issues

Ahh i remember this site, lost a coin a while back :P

The website itself doesn't seem to work anymore. It keeps trying to connect to the server.

works for me.

http://minefield.bitcoinlab.org/?r=VbkB3lYHZr5AkDWn

It does now yes.

thanks Bitcoin MineField , I just won some btcs.

hi, there are a few support requests waiting to be resolved, I've been away for a bit, everyone will receive replies tomorrow, sorry for the delay.

Just deposited a dollar into this, then the site went down.  :(

I deposited .0045BTC and the system went down or froze and i cant withdraw the remaining BTC i keep getting an error message? Help!!!      i love playing this game. with BTC or with out its alot of cheep fun. my address is 1aqv8NmGpN6BoW4HBYT4kJaJwoUWDLnTF

user-5279124c272948a23d0272d2

Hi, I tried to deposit 0.0099BTC and it is not showing on my balance. It's been about 8 hours and still nothing.

Any suggestions? My user id is: user-529950b68476b7dd750117cf

Cheers

Hi people, I was away for a few days, sorry.

a lot of people reported problems with deposits in the last day or two.. I'll message each of you and deal with it in the following hours, your money is safe.

Hi, just send 0.1 BTC to this adress : 1DRaoTrwN1sStaKh5LbQK2UYMEt9KCW2ht

And nothing deposited ... ?

Regards,


Vince

I've shut down the website for now in order to resolve that deposits problem, the service will go online later today

deposit some coins before 8-9 hours still nothing... :/

Reeeead.

I just made some BTC from here!
http://minefield.bitcoinlab.org/?r=VbkB3lYHZr5AkDWn

so, everything is ok now, site is up from yesterday, deposits that haven't been processed are processed now.
let me know if anyone has any more problems

Working great. Thank you!
http://minefield.bitcoinlab.org/?r=JMeZjs0dOHB42TsG

SPent a few hrs with some bitcoin change and had fun :D

BTC282.288? I lolled.

haha me too.
so - service is offline while I investigate how bitcoininformation exploited the service and got 282.288 BTC

That wasn't me dude. There was a guy who posted a screenshot showing that much. He must have deleted it. (Can't a moderator check that?)
I will try to find the screenshot for you in my Google Chrome cache. Nope, it isn't in there and I already know why. It's because Bitcointalk doesn't allow caching. Well, it doesn't allow caching in a way that I could retrieve the images from the Google Cache.


Anyway, I did not abuse your service nor do I intend to.

bitcoininformation exploited site, bad boy ;/

He just posted again, but removed his post before I could screencap him. He said that he would tell you how to exploit your website if there was a big bounty in return. This is his profile: https://bitcointalk.org/index.php?action=profile;u=157527 (https://bitcointalk.org/index.php?action=profile;u=157527)

EDIT: And now he is trying to frame me, good move dude ;) Well holorga, it's up to you who you believe. You can choose between a member which contributed to the community and has positive feedback or a guy with negative feedback trying to blame me.

http://img.ctrlv.in/img/52cc51af983d4.jpg

LOL, i am just kidding:)))

someone somehow got into my accoumt, event though i never post the link anywhere.

Thank got they only stole 0.004

hi, bitcoininformation, thanks for the info, no, I don't think you exploited it, its ok :)

about reports of your balances getting stolen - nope. that's you losing your login. through your machine or network being compromised if you didn't share it with someone..

btw, not paying the bounty but solving the problem myself by going through logs, in a few days, not able to deal with it atm,

will be online soon

in case anyone wants to take their btc out before the site is online, just email me your secret and address and I'll send you your balance.

Your game is awesome, I hope you figure out how it happened.

thanks! and its not a big deal, will be online soon

why has it been down for like a day?

Read the posts above and you will know.

oh....  ::)



Yh a litecoin minefield would be just as awesome as the prices are about to shoot up too.

we are back online!



I'll think about litecoin seriously soon, I got a good number of requests for litecoin.

I cant cash out to a different wallet.

cant withdraw with any address, i keep getting the message "Something is fishy"

sorry, I introduced a bug in code changes, people with referal earnings couldn't cash out, fixed now..

Cant Withdraw too. "Something Fishy" Thanks for the great site

Same here! Can't withdraw my btc as well. Please help

yes, I received a bunch of reports on problems with cashing out due to new security features, I'll solve this problem asap

I've seen a few threads like "win 19 BTC from minefield in an hour".  I assume you are aware of these strategies and they don't actually work?  ;)

I haven't seen threads about this but I've seen some youtube videos, and of course they don't work, if such a thing was possible the website would exist for 2 days. the math around the game is simple, its easily provable that there is no winning strategy. long term - you lose, like with any gambling.

I think people are just trying to steal bitcoin from people by earning from referals. I should add this to some kind of an FAQ

cant withdraw, I get the "Something fishy" popup.

How do I fix this?

hey, this has been an issue for a few days now for some users, I'll fix it soon, and if you want to cash out asap, just send me your userid and address and I'll cash you out manually.

hi, i hope to play this game enough, i feel lucky

but ive noticed (and read that it has a few bugs)

im not complaining about my loss of 0.0009 btc, but i will be coming back with more than that so i just want to get some feedback on a few things

the transferring of btc to the site worked fine, but my transaction to it is listed at the transactions section and it still says 0 confirmations

also, when i tried to cash out the 0.000081 i had left, it just said transaction unconfirmed and didnt do anything

so, if your transaction has more then 6 confirmations (check blockchain.info) then this is a bug, but a very uncommon one. ( this used to happen here and there but it was fixed and I haven't had this kind of report in months ) if it is a bug please give me your userid or transactionid and I'll look into it.

there is only one known bug atm, some small percentage of users gets 'something is fishy' message when trying to cash out.
this is an internal security system triggering and blocking the transaction, but it sometimes triggers on honest users.. in that case they message me and I get it cashed out by hand for now, until I manage to resolve this, which will be soon.

if you end up playing, good luck :)

i guess it just takes a while, im fairly new to bitcoin but i know the basics, i guess i just didnt think it would take that long but its confirmed now

i mostly just want to make sure i can actually trust that i will be paid out, i tried taking out what i had left (a little less because of fees) and it didnt work, im guessing you can only withdraw over a certain amount?

my transaction id is 1LzLg5guj2GQZo7YQVgizXd6pvRQssUepR, i am not asking for a refund of my 0.0001 btc but a few plays would be nice, also my friend is most likely going to try this and i am using the linking system so maybe i can earn something off other people :P

i plan to buy some btc later for this, excited to see if i can make some, needless to say ill be around for a while, its odd i find something i can gamble on that i feel this good about and i like what you have going on here  :)

you gave me some btc address, not transactionid

I won't explain btc to you now, you should probably just wait a bit, confirmations number should go up within an hour and you'll be able to cash out soon.

ahh okay, its no biggie, i trust that it pays out and all that

if im not mistaken the transaction id is the long code at the top when you follow the transaction to blockchain?

dont worry, i know most of what you need to know its just working out the little things i need clarification on

thanks for your time

sigh, when I wanted to take out my btc I couldn't.... now I gamble it all away. GG

you could have! as I said, just send me your userid.


---


I believe that withdrawal problems with 'something is fishy' message are resolved now

if you are an existing user with this problem it is possible that you'll need to msg me to resolve this, just provide me with a user id, sorry for the inconvenience

all good.. i have tested and yes your  btc withdraw is definitely working again :)

now i am getting insufficient funds error when i try to withdraw... obviously i have the funds.

I am guessing that his hot wallet is empty or doesn't have enough to fulfill your request. The only thing you can do right now is wait :P

yup, hot wallet got empty, funds have been sent, you'll be able to withdraw in a few minutes.

is this some kind of spam?

I love this thing. It's fun and really heavy on my wallet.

Made it to 2 BTC with 0.5 deposit then lost it all.  :P

sorry, i just try this site few days ago
and when i want try again today
it already hv 0 balance
i think it hv diff user id with i use before
i think at that time, i dunno that i should save my user id
cause i think its will auto login with lock ip
well...my point is...i cant use my user id bfore
still hv balance there
how to get my user id again???
if i not wrong, i deposit with this address

Shoutout to the owner, one of the very first BTC games I found when I discovered bitcoin. Nicely made website for being one of the first.

Loved this game, however it's stuck on connecting to server... Is it using a non-standard port? I can only connect to port 80 or 443 :(

Liam

yeah, non standard port for websocket connections, sorry..

you deleted the cookies or changed browsers and didn't bookmark your url, I can recover your user but you have to give me some info,
those addresses you mentioned are not deposit addresses used at minefield, can you please give me addresses you've sent the money to or transaction ids?

sorry to many address i hv ;D
this tx id
1e94ddb7b0eaa96ef934feb26f6de53bc85c645057cf869def6650f7e03828b0

pmed your secret

Is there still no Android app? I have a right mind to make one, with the help and permission of the OP...

Liam

According to a source, it should use port 80 :P

nope, you are missreading the source :) but according to... being nice, it should use port 80, maybe some day it will.

You gotta a great game Holorga. I do have a suggestion...it would be nice if you had an empty box/field where we can type our wager amount. I myself like playing a martingale system (example..lose .01 bet .02 lose bet .04 and so on)

No matter what ....you have a very Fair Game and I will be playing it for hopefully a long time

Thanks  ;D
BgW

Is the website down or can i just not connect?

Not working for me either...probably something temporary

Whatever is was seems to have been fixed. Lol. Is it bad i mostly play this site on the free version?

thank you! I received this request a few times and I'll consider implementing this in the future..

yeah, some temporary network issue it seems, and no, you can play free as much as you want :)

Something I would really like to see implemented into the site is on the upper right hand corner, or between Referrals and Faq, have the amount of BTC available. As in how many BTC are there for winnings and have it update itself so that people can watch as others win/lose

I've never thought about it much because it was never a problem or relevant, in theory, infinite ammount of btc are availiable for winnings..
when it happens that a person wins more then it is currently availiable on the server, I send aditional btc so that the person can withdraw.

but I know where you are coming from - I'd like to see what other players are doing, kind of, in some form.
I'd like for some kind of interaction between people, but I think that this may not be a right kind of a game for that.. I'll make other games though, that will involve more interaction between people.

Alright. I just wasn't sure how the winnings were done. Also, it would be awesome to show a top scores tab. So that people might have a goal, and use your site more. Rather than just use it to gamble, it'd be neat.

that's a good idea!

please help my balance recovery....


this is my payment....

https://blockchain.info/tx/2d8d8c7d9a626f261fdf2f7398edb60b40780febe2425529cce635bf7e6a11ff



im not deleted my cookies,, and not change my browser,, but why my balance is 0 today ..

thanks,,,

no need to send pm and public msgs..

your balance is not 0, if you got logged in as a new user, your cookies got deleted, you might have not done it manually..
pming your url to you - bookmark it

I am playing minefield but coin did not mine when i click on box without mine. Is their need of special machine to play minefield?

server is undergoing RAM upgrade and some other big changes, the service will be offline for the next few hours

took a bit longer, but we are back online.

How long does it take to see my deposited money  on my account balance?

less then a minute, if it takes longer, make sure you've actually sent anything by looking up the address you've sent btc to at blockchain.info

lols, already 6 confirmation,

i use Coinbase by the way..

but still no balance received, T_T

Here is my transaction for the Deposit

https://coinbase.com/network/transactions/a36cfbdb410285b7def598122062d14c53ecfcdb554d034285b1fd7ff7b17707

this is my user ID

user-5342921a04e2a84c14000e74

credited your account by hand


there was a bug, new transactions were not registered in the last 24 hours
this has been fixed and your acconts are credited now
(bitcoind hasn't been receiving new blocks due to firewall misconfiguration)

Any chance of allowing custom bets up to your max bet and improving the site? It's been the same for years! Surely you've made enough to improve upon it and increase functionality?

I have, and I took that time to work on a much interesting project involving btc,
but custom bets have been requested many times so ok, I will take the time off a bit and implement this

Hey mate, I get the error:

"Error: Insufficient funds"

when withdrawing.

I have sent you an email. but I see that you havent come online here for 4 months now :o


Please check you email. Thanks

EDIT: Because I have gotten over 50btc in this. I think it has an automatic cap.

My balance is 40+ btc, but cant withdraw it.

(Im semi-scared you may run off with it because its soooo much)

wtf. 10btc randomly disappeared from my account :o

It went from 53 to 43.

From 43 I went down to 20 for gambling.

BUT, I should have 30 correct?

EDIT: Wtf, Iv been trying to withdraw it, It says not enough funds, but subtracts the amount from my acount anyway????????????????????????

I only has 0.9 in it now.....

wtf...
I want my money

After trying to withdraw it, the funds got subtracted but I got an error.

Im missing 30btc from my account.

Its only showing 0.04.

Please sort this out ASAP, im emailed you.

ugh,.. mate this is like losing $20k.

I hope you havent gone rouge.

Rogue, you meant? Well spamming isn't gonna help as he hasn't been on in 3 months. Just wait a few days for him to reply to your email then update here if needed. Good luck!  That's a lot of btc to lose!

Sorry, yes Rogue. Im really annoyed that this has happened. Im sure the admin is just away for a bit.
Im sure Hologra is legit though,
Im scared he might have gone rogue due to being 450btc richer

But dam. Losing 30btc due to a glitch....  :(

EDIT: Site is in maintenance mode, I think Hologra is fixing it.

EDIT 2: Or the site may have crashed, forwarding to another page?

Looks like it crashed or was shut down suddenly. Let's wait and see what happens!

Some kind of a bug was discovered in the service, I'm investigating, will be back online soon
casinowinner - those 50 btc you randomly received were part of a bug.

Casino winner tried to cashout btc that weren't even his? Lol! That is hilarious. Some people...

Im very disappointed how this bug occurred.

I got over 9k refs, and earnt over 7btc through refs, now hologra said he wont provide any support for me due to all the emails.
This is BS and im not going to use this anymore.

If I earnt 7through refs, he must of have gotten 70btc (63btc).

And why did this random bug occur yesterday?

Also my referal earning had an addition 50btc in it.

whatever man. Im very disappointed. I only emailed you because I thought I have 50 btc, then the sire crashed. 50btc is alot of money. Im sure anyone would have done the same.
Its a shame.

Please send whatever money owed to my wallet I emailed you, so I dont have to use your service anymore.
Your welcome for all the traffic I got you also.

I dont understand how my account magically had an addition 50btc through refs.
And it happens to be a "bug".

Hologra then emails me this:


why did it show on my account?

This is bs, its like being scammed and ditched.

You lost your password a few times, your machine got hacked a few times, we've exchanged 30+ emails, not counting forum pm-s,
Sometimes you send me a few emails + forum message + forum private message before I have time to answer the first email,
I know I'm being too harsh, I know this is not nice of me, but I think its my right to do choose this. I just don't have will and time to deal with that.

this is not BS, you are NOT being scammed, I will post the details of the bug soon. I believe that someone that used your referal url found a vunerability, will make sure.

My link was never stolen via my machine being hacked. I originally came to that conclusion, but no malware was found on my machine.  I believe it was found via a vulnerability from my ref.

Oh well, can you please just send whatever btc I have left to my wallet I emailed you please? Then I will go. Ill get refs on another btc service.

found the bug, it was very silly, will be online later today

I cant withdraw, Please send it to my wallet.

emailed you

still cant withdraw

Withdraw are tempory out ?

Its been over a week now and still cant withdraw

Its ridiculous, because then it makes you want to gamble more.

Why am I less likely to hit a mine if im gambling with 0 btc?

Anyone can try it for themselves if they think im BSing. Your more likely to lose when you play with btc.

Anyway, still waiting for my withdraw.

Over a week and still cant withdraw, I think he has done a runner

Cant withdraw

please cash out my bt:
User id user-53d9146ce602c6731d003f0e
Adress 12cp7RTVgo1cpSyV99uGyc1oz74eYnQir3

Thanks

I've gotten a few reports of withdrawal problems in the last 24 hours, working on it, it should be fine very soon.
casinowinner, no, I haven't "done a runner, I will look into your case. I think your problem might be different in nature.

OK, bug has been resolved, it was introduced when patching a security problem discovered recently.
I am very sorry!
everyone is able to withdraw normally now.

casinowinner, please let me know if you run into any problems and I will deal with it asap.

can i get some free to try??

sorry, didn't implement a feature like that.
but you can just play with 0 bet.

sorry mate, I misunderstood you.

Im very sorry.

May I continue to use your service? I will not contact you anymore.

Sure, you can use it, you can contact me if you are reasonable, like, message me once, on one medium if you have a problem and don't lose your url all the time.

I wont.
Thanks mate :P

I have deposited 0.5 BTC and won 0.63903475!!!

Im trying to send it back to my but it keep saying insufficient fund.
I have tried to do it in smaller payments like this:
10x 0.05BTC , 12x 0.01 and a smaller one with the rest of the BTC. it did'nt work.
now there many missing payments. :(

Now im seeing only 9x 0.05 BTC  2x 0.01 in the history balance.
in total i received 0.47 BTC in my wallet.

So i am missing 0.16903475 BTC!! :'( (its a little bit to much for some kind of fee).

Can somebody please explain what happend.

please contact me on j.q.balker@gmail.com

hi, you should have just waited for my reply, server wallet was emptied, I refilled it. withdraws should work ok now,
I will look into what you did and what happened, and get back to you via email.

I am quite surprised this is still up, This is one of my first bitcoin gambling games.

Yup, this is one of the oldest bitcoin gambling sites.
For comparison, the game launched in Jul 2011, while SatoshiDice launched 9 months later in Apr 2012.

Might you be making any more gambling games in the future?

The site doesn't stop loading...

Ok, sorry.
know it works fine...

This was one of the first games i stopped by. It is simple but still gambling. I thought i found a "bug" so i can win but i was mistaken... :)

yeah, will go online with something else soon, not a gambling game but a skill based game this time..

I get an error when I try to withdraw "Error, Insufficient funds"

fixed, hot walet got exausted,wait maybe 10 more minutes.

hello im trying to withdrawal right now and it keeps bringing up a "transaction unconfirmed" message

you should wait for all your deposit transactions to have 5 or more confirmations. (simply wait for about an hour, it will happen by itself, if you want to know more you should read about bitcoin)

How do you get bitcoins when you start with 0. Is the adress the one in the top left. What is the withdraw and deposit thing. Please explain the game to me

hi, having some issues, will be back online shortly

Site is down..... wanted to try it!

back up!

migrating to another server, will be online shortly.

Hey there, Im getting this when I try to withdraw:
https://i.imgur.com/p84kyPH.png
My referrals have been increasing lately.

I think it means the server wallet does not have enough to withdraw.

Hey people, sorry for being out of touch, my laptop died.

You are right, server is out of funds, recently I got a lot of high rollers, and they all won and emptied the server wallet. This is a bit suspicious and I will investigate in the following days.
sorry about the inconvenience! In the mean time, please don't hammer the server with cashout requests, let people that play with small amounts play, you will get the btc you deserve :)

will keep in touch

yeah, totally

too high house edge .. :(
so i will not going even to try it..
regards.

Hey people following this thread, just letting you know we've launched a new website
a multiplayer game engine - running bomberman for a start.

http://battlecoin.org

we are super interested in sharing BTC with users that refer new users - as this is a multiplayer game, we need a critical mass of people on the website.
we give out 100 satoshi per user you refer and more importantly 10% of our profits from that user.


thanks!

This game reminds me of my childhood days! :) It's user interface is awesome. It would be better if you add a faucet where one can claim some BTC if he loses multiple matches! Also it would be more intuitive if there is a chat between players during an ongoing session. Hope this site gets more notice from the community members :)

thanks for the feedback, yeah, I'm also missing the chat.
and we are playing with different faucet ideas to get more players to join, (tournament will be one of them)

Really nice to see a bomberman game with bitcoin! I gave it a try and it worked really well, no delay and everything seemed very smooth. The main issue will be, as you mentioned, getting enough players to keep the games going constantly. I think there will be user interest because this is one of the games where skill really does matter and it does not just boil down to luck. I am thinking about promoting it a bit, will see if it pays off :)

awesome, please do, people are starting to play, but we need more. we'll also experiment with giving up to 25% to people that are working early on refering, will need to implement this.

btw here is the original thread about this game,
https://bitcointalk.org/index.php?topic=1010288
