What is SafeDice?
As its name suggests, SafeDice is a secure and provable fair dice game where people can bet and invest Bitcoins.

Introducing Variable House Edge
SafeDice is using a variable house edge. By default, the house edge is 1% with a max win of 0.5% of the bankroll. Players can also have a higher max win with a bigger house edge, for instance, under a house edge of 2% there will be a max win of 1% of the bankroll. By implementing a variable house edge system, we are expecting the players to enjoy a better experience and investors to have a nice profit.

Play and Invest
You can play and invest at SafeDice. The game is provable fair and the results can be verified right away. You can also simply invest your coins to the bankroll for people to bet against.

Security Matters
By enabling 2FA authenticator, your account's security is taken to the next level. Most of the coins are kept in cold storage which is separated from the server.
If you are using Tor and want to access SafeDice, you might have to enter captcha verification frequently. In this case, you can access our hidden service at safedice2ge73n2g.onion.

A Warm Community
We believe that building a friendly community is essential for a dice site, that's why we have a chat room, looking forward to talking to you there!

Nov 18, 2014 - Announcement for Investors
As some of you might have following this thread discussion, we will implement a floating Variable House Edge system soon. We expect this feature to be launched within this week. While this feature should not affecting the risk of the investment (we will still use half kelly criterion), this is a modification from our current game system. In addition, we will also lowering our house edge for a roll below 0.5% of the bankroll to attract more players. Please make your decision as the changes might happen anytime soon, you can divest, keep your investment, or invest more if you also believe this system will succeed :)

Nov 19, 2014 - Investment feature will be disabled in the next update
Following our recent discussion with some forum members. We think it is best to close our investment feature until indefinite amount of time. We admit that currently we are still to new for this type of feature and the community just get shocked by the recent cases. Continuing this feature will not only harm our brand, but it might implied that we are insensitive to the recent cases.

• Will you open this feature again?
  We might open the investment feature again in the future when we work with a partner that is trusted both by us and the community, or when we believe we are ready and there are lot of request of this features.
• I still have investment in my account, what should I do?
  If you still have your investment in your account, you will still be able to use it.
• But will the site be playable?
  We will use our Variable House Edge system, this will allow us to run the site with lower amount of bankroll to a certain limitation. Meanwhile we are looking for a better solution.
• But I really want to invest?
  You will need to contact us privately for this matter.

Reserved for future updates.

setting a custom win chance doess not work, i cant bet..

Thanks for visiting best, can you elaborate on the process? Because we saw some people already made some bets with custom win chance.

when i bet with 50% chance, bets go through. When i change the chance and click the roll button, nothing happens. When i put it back to 50%, it works again.

I said this before for Dice.ninja, Dicebitco.in & Everydice. All three of which stole millions in BTC.

Investment sites are extremely high risk. Do not trust unknown third parties with large amounts of coins.

@SafeDice, close investments and slowly build up your bank roll yourself. It'll be more profitable that way for you that way as well. If you're adamant on taking investments I'll be happy to verify your identity or help in 'escrowing' investment funds or server seeds. I recommend Dooglus for this job however as I'm sure he'll happily do it.

Ah, got it best, sorry for this. All you have to do is to refresh your browser and please make sure that you have Javascript enabled. Thank you for noticing us and please let us know if the problem still persists.


Hey Stunna, glad to see you in our thread. We always respect you and dooglus as the trustable guys in this business :)

The site actually starts with 10 BTC. But new players start playing and won 0.1-0.2 profit in few minutes.

Currently we don't have much coins, we already spent a long time designing and developing this site, however, we are going to buy more coins from the market and will deposit to the bank. We know we are new so it's hard to convince investors now, the only thing we can do is to build our reputation in the long term. We sincerely ask people to test with us by depositing small amounts.

Do you think by any chance if we can have some kind of partnership? If will be awesome if you can help us, as you can see, we spent lot of time on the site, and we do have the ambition to maintain a reputable business like PD or JD.

If you were here and saw what happened to the sites that dooglus was advertising. You will have an idea what stunna's answer would be

We saw what happened here and we are really sorry for those who are affected by recent DN and DB cases. Those cases hurt the community and also put us into an uncomfortable situation. It's understandable that people will try to compare us with our predecessor's action. However, with or without SafeDice, new dice sites will keep on coming, some of them might be bad, and some might be good. As we know casino business is a lucrative investment. We know in our heart that our mission is to run a sustainable and profitable business. With this mission hopefully we can be one of the safest choice for people to play and invest (without judging that there will be a new site with bad intention, of course). Our current strategy is to let people to decide. If not now, maybe few days, weeks and months later people will learn which site has good intention and capability.

how about you add faucet for a few days so we can test the site :)

Why anonym, how many devs in team?

Faucet is important so that we can try the site out.

Thanks for the suggestion Big and Clint, we don't have a plan to include faucet to the site at the moment. We might substitute it with occasional giveaway event in near future :)


Hi there RoooooR, If you mean the anonymous registration feature, it is provided for the players' convenience. If you refer to the devs, it is because the nature of gambling in cryptocurrency, as this is quite a grey area, it would be best for the devs to stay anonymous. Hopefully this is understandable. Our team currently, consists of less than 5 persons, with only one person handling the server area.

The site allows 0 bets so faucet is not really required. You can try the bets with 0 amount if you just want to see how betting works.

P.S I like the design of the site. Looks fresh and clean. I would add a small box around "Roll Low" similar to the betting areas. Would make it easier to find as its a rather important feature so highlighting it would be a nice touch.

very nice went to 0.15 + from a deposit of 0.01 :D also received bits to my wallet :D https://blockchain.info/tx/103e758981028d0acf21a6d9bd891d4ed21c462e2e465470352fbf9c4c90c043

Very very nice site. I am jelly.

faucet invites bot users thus makes the site slower and some beggars that spam.

Thanks for the suggestion! Do you mean to move the roll button? Because it is already there in the bottom-left. We will consider this.


Congrats! I guess you are player-57 then. That's 15 times multiplier, maybe you can share your strategy to other people? ;)


Thanks.. Jelly? :o


Thanks for the input Seketsuna, this is also our consideration.

So... SD? People will get confused between SatoshiDice and SafeDice... Oh well.

The game looks like my iPad mini with the gradient colors.

However, the server seed is NOT shown BEFORE I am allowed to set my client or account seed. To be truly provably fair, you must show the server seed hash, and then allow the player to set their account seed.

Your 2FA QR code does not have the required white space border around it, also known as the quiet zone. I had to save your QR code and open it on a white background before my phone could scan it.

Try it like this:
http://qreateandtrack.com/files/2011/07/quarter_inch_image1.png

Hi there Dabs :) Thank you so much for the suggestion. We got your point, we will change the provably fair method as soon as possible (it's already fixed. the previous method doesn't mean that it isn't fair, but Dab's method is certainly better, thanks Dabs!). For the QR Code Actually it can be scanned, but we agree that it is quite difficult at the moment (fixed too).

The design of your site is great and pretty original IMO. :)

On the withdraw page, there is a line "All your deposits must receive enough confirmations before you are allowed to withdraw." I would suggest you to specify exactly how many confirmations are required.

Hi Chemistry,

Thanks for testing the site, confirmations required depends on the deposit amount, we've specified it on the FAQ page: https://safedice.com/faq

so shiny & futuristic site  :o
And I think this site will be famous as PD

Something is missing...
auto bet & affiliate program ;D

Looks very cool, I will definitely try it out.

Hi Dabs, the fair calculation has been modified so it shows the server seed hash before the player able to set his account seed. We are now using the similar way JD has been using back then. Actually just to confirm, the previous method still doesn't allow the site to modify the bet along the way, although I just realized that it enables the site to set the server seed based on the player's behavior (but still the most beneficial way for the site itself is pure random). However, thanks for pointing this out.

We have also fixed the QR code visualization and adding 1X quiet zone (as suggested on https://qrworld.wordpress.com/2011/08/09/the-quiet-zone/). Thanks again Dabs!



Thank you so much for the appreciation guys! @lontong, thanks for the suggestion as well, we'll discuss that on our development plan

The password field on the login form has a max length of 15 characters. I assume this is a mistake and means that people with a longer password cannot login atm.

Yeah, I am account number 69, and I can't log in with my 32 character password anymore.

Sorry for the inconvenience, we just made few changes on the validation and it got affected. You can try again now :)

guess ur chinese, the languages listed only english and chinese, layout pretty good, u need more advertising push i believe, and i just found out this today

The Chinese flag is right, but the English flag isn't. That looks like the USA flag, not the English one.

Impressive job. Minor nitpick, on the splash page you should fill probably prefill the input box with the attribute placeholder="player" instead of: value="player"

https://i.imgur.com/59Hh50l.png

Welp that was a pretty unlucky streak.

I tried experimenting with the variable house edge, checking out what chance it would give me of doubling 1 BTC or 2 BTC.

After a while things stopped updating.

I checked the console and saw errors:

https://i.imgur.com/Kf7MU8S.png

What's the maximum house edge? I didn't see it go above 3%, which presumably means you can profit by 1.5% of the 10 BTC backroll, or 0.15 BTC. Maybe that's what caused the crash.

Also, if I'm trying to edit a stake of 0.001 to 0.002, I go to the end, backspace over the '1', the site notices that the 0.00 left in the box is just 0, so replaces it with '0'. Then I type the 2, and I'm betting 2, not 0.002.

The site shouldn't try to be so clever - it shouldn't try to edit the same box I'm currently editing. I should be able to go to the end of 0.001, hit backspace then type a '2' and then see "0.002" in the box, not just "02".

Nice work, welcome on board  ;)

Not a bad site, other than the fact that its another dice site  ;)
 I would suggest against a referral system. People will just refer themselves to make a rakeback of what they lose/win.



Wish you luck on your venture! This could be a huge success if you make the right marketing moves and such.

Sorry for the confusion Doog, it was meant as American English, but I realized that it is not common and just changed as suggested.


Thanks Rhavar! We did it on intention because it is an alias (optional), so people can just left it with default value.


Thank you so much for the catch Doog! We just fixed both glitches you mentioned :). We also notice the same happen for Win Chance and Payout box, we'll look into this soon.


Hello fellow op! Good luck for both of us :)


Thanks for the advice Mist, will note it :)

Want to share my bets with you guys.
I can say its good and secure site, i have recieved my winnings in few seconds, I hope they will stay at the same and try too improve the site more and more, it will become one of the best im sure.

good luck

http://s28.postimg.org/4t5y601sd/fffddswwwww.png

LOL another dice site , well good luck !

I would love to play there if i have luck ;)

Thank you guys! We will do our best to improve the site, of course  :)

You missed the point about the maximum house edge. It looks like I can attempt to win 20 BTC by betting 20 BTC with a 48.5% chance. That's only a 3% house edge, when I'm trying to win over 100% of the bankroll.

Also, why would you only adjust the house edge in whole percentages? It would make sense to offer the exact "right" edge. If I'm trying to win 10% of the bankroll, make the house edge 20%, if I'm trying to win 10.001% of it, make the edge 20.002%, etc.

You could consider going lower than 1% too, for small bets. Then you'd have a real unique feature to boast about!

After logging in, a UK flag is shown now; but before logging in, a US flag is still shown.

I just tried setting a username and password.

I typed a 32 character password, twice.

It told me "Minimum password length is 6".

It turned out it didn't like the exclamation mark I had in my password.

It would be better if you allowed weird characters in passwords, or at least told the user what the rules are, rather than saying "minimum 6"!

Not all luck, you need bitcoin too. :)

Hi Doog,

What do you mean by missing the point about the maximum house edge? Can you please help to elaborate?

We also thought about floating house edge the first time, to have variable house edge using a proper kelly criterion. And then, we thought that it might be a difficult to understand concept to new players and investors. Plus, we wouldn't be able to advertise the site as "1% house edge." That's why we came out with the "semi floating" idea. There's also one consideration that using total floating might encourage players to make a dust bet.

However seeing this post is made by you, it really make us think twice about our decision. We will discuss this internally and probably implement it asap. Thanks for the "site changing" post :D


Sorry for the inconvenience Doog. Noted this and will fix on the next update  :)

I tried to set my client seed. It told me "bad request", but not what was wrong with it.

Seems there's a limit of 15 characters - if so, tell me. "bad request" isn't helpful.

I've typed "0.00000010" into the stake box, and am trying to type "1000" into the payout box. As soon as I hit the "1", the payout box changes to "1.02061856". I don't know why.

There's no significant error in the javascript console.

I don't think I'm trying to do anything very weird - I want to bet a little on a high multiplier - but I can't figure out how.

Edit: I tried putting 0.001 into the chance field, but it changes to 0.01. And if I hit backspace, the field becomes just "0", much like I segnalationed with the stake box earlier.

Edit2: Maybe 0.01% is the hardest bet you allow. I managed to win it with a small stake:

https://i.imgur.com/0XqY958.png

The site looks pretty good, but has a few annoying issues, reported above.

Edit3: Withdrawal of 0.56 BTC was instant. It would be better if the withdrawal dialog made it clear whether I was meant to type the amount I wanted to receive or the amount I wanted to go out of my balance. They're different by the fee of 0.0001 BTC, see?

House Edge is 3% ? No thanks. But your designer knows his business, good ui.
Also I didn't deposit, made bet with 0 satoshi. It was so slow because of 0 satoshi?

@Doog: Thanks for the comprehensive test and 'segnalation'... And sorry for the inconvenience. Will look into it :)


Ummm, actually it is 1% by default, 2% - 3% are optional for player that want to bet higher than 0.5% of the bankroll. And yes, there is a delay for 0 satoshi :)

i think you should make a giveaway and add a faucet to attract more players to your site

It's a nice UI but the wrong time to open an investment website imo. I don't think people will invest their coins into new websites anymore, pretty sure everyone has learned there lesson.

Agree, and that's why the site has received very little investment.
The bankroll starts with 10 btc and is now at ~9.75 btc after losing ~0.44 btc, so there is less than 0.2 btc investment.

I saw this bet " 22150   rexxludi   69.0709   < 88.3929   0.13430087   1.10 ×   0.01307730 "

I think there is a problem because if 1.10x the target must be 89.9999 ? right ?

Hi CoinCollect, at that time he is using 2-3% HE calculation (depends in the bet size), in that case the payout and target is correct.

Yes, its quite difficult time. People have their limit, not all, but majority and bigger player & investors might stand back for quite a time. Sad to see the industry destroys itself.

This is a good question and as you are also not the first person to mention this :)

But we don't think waiting longer is a good idea either. We are agree that trust is important, and it is build, not made in a single night. For this reason we believe that the sooner we launched the site, the more time we get to prove ourselves, and the more time we get to improve the site. By the time the industry is healed, the site will be more "ready," both in term of features and trust-ability.

Thanks Doog, both of them have been fixed. We will also recheck through all the notifications within this week :)

I guess what he means by the wrong time is that it would be much better if you just had launched the site sooner, not longer.

This is what I'm experiencing too, seems it's not fixed yet.

Hi nothingnew, thank you for the inputs, we will fix this as soon as possible.

And thank dooglus for testing the site, as a  new site in this industry, we are so grateful :)

Ok, so the house she was high on this one but still, 0.13430087 times 0.10 isn't 0.01307730! You're off by a few percent.

Hi Dooglus, because it shouldn't be 1.1 payout, it is actually 1.09737321 you can test this is right by multiplying the payout and the win chance :)

The payout shown in the bet box when the bet was made will be 1.09.. and the payout shown in the bet details is also 1.09.. It is only sown 1.10 in the log table because it is rounded to two decimals digit for simplicity.

We will modify the payout in the log table to show the actual number in the next update.

     
            Why the website can't open?

How many chickens does it take to cross the road?

    I used the VPN also won't open.

Hi nothingnew, all glitches in the stake box should be fixed by now, thank you for the input again and sorry for the inconvenience.


Hi fangj1n, can you please describe how does the site not opened? Do you sawCloudFlare's verification? Or it just doesn't showed at all?
Except you just very (un)lucky to access the site while we are updating it, everything should be fine :)

Nice site, nice design! Hope you aren't T04D or so.

Nice site, surpisingly awsome design. You guys really did put some effort into this project  :P
Good Luck!

Do you accept only BTC or are you going to add other crypto?
Btw nice disign I like colors and background

Umm, if we were him, we'd rather continuing the site rather than close the site and start from scratch  :(


Thanks guys! Happy to hear that... Yes, we developed the site to be ready for other crypto. But we would like to focus on BTC first, getting stable before we go with other currencies. Just like what JD did before launching Doge Dice :)

Max win is 0.05247555 ?? thats one of the smallest ive ever seen you should make it bigger asap

The bankroll of the site determines this amount. The more there is invested the greater the 0.5% portion of the bankroll that can be risked per bet.

Nice to see that the site isn't exactly a prime dice clone. What percentage of the bankroll is the max bet?

By default, the house edge is 1% and the max win if 0.5% of the bankroll, but the house edge and max win are floated.

On the high bets tab, you can see this bet https://safedice.com/bet/33843 , the player-160 bet 0.15830207 BTC for a 1.95959596 payout, that's because when the max win is bigger than 0.5% of the bankroll, the house edge floated accordingly.

Currently, the house edge is capped at 3%, and we'll lift it to unlimited very soon, that means you can take away the whole bankroll with a single bet under a high house edge, stay tuned guys!

And thanks to dooglus again for the great advices:)

I don't think so:

You can win 0.5% of the bank with a 1% edge,
Win 1% of the bank with a 2% edge, etc.

So to win 100% of the bank, the house edge would need to be 200%.

percentage_chance_to_win = (100 - house_edge_percent) / payout_multiplier

If the house edge goes bigger than 100%, the player's chance to win goes negative...

So the most you can let a player win in a single bet is 49.99% of the bankroll.

At that point, supposing they want to double their money, their chance to do so is (100 - 99.98) / 2 = 0.02/2 = 0.01%.

So that's a one-in-ten-thousand chance of doubling their money.

In other words, there's a point at which it becomes silly, and the player would be better off just using a site with a bigger bankroll...

Sorry for I didn't think it clearly enough. Yes for a default of 0.5% max win with a 1% edge, it's impossible for a player to take the bankroll through a single bet, it only happens when the max win is 1% of bankroll under 1% edge. But the chance is just too tiny which is like a jackpot :P

Will you be allowing investors to specify the maximum percentage of their investment that they are prepared to risk on a single roll?

It's possible that some of them wouldn't want to risk 50% of their coins on a single roll no matter how high the house edge was.

That would be a great feature!!!

We don't think so Doog, it would be complicated. It's also doesn't make sense if a player bet on a super high HE, just as you said, in that case they'd be better off betting on another site with higher BR.

So, our current idea is to cap the HE between 0.5% to 10%, depends on their profit on win / bankroll ratio (we'd like to keep it at half kelly). Do you think this would be a good idea?

Another thing to consider is that the site will be deciding a bet's HE in real time, so if there's an invest/divestment when the bet request is sent from the client to the server, there might be a slight difference between the HE shown on the client and the server's calculation.

And Doog, if you have the time, would you be interested to test this new feature when it is finished, but before it launches to the public? :)

Everytime same thing is happenning. I can imagine after this:


And then one night run away. Simple.

UI is good but isn't giving any confidence. Maybe it's just a hoodwink? I don't like your anonymity.

We were asking dooglus for help simply because we take him as our hero, I think a lot of other people appreciate and admire him as we do. When dooglus replied our thread, we were not just excited, but were determined to not disappoint people like other bad examples.

We think that if we can be as successful as JD, we can have a very decent incoming without being cursed, and no one wants to be cursed because of stealing people's money. It's not cool.

We also believe that, a sustainable dice site is helpful to the bitcoin community, we are believers but now speculators of bitcoin, and don't want to do anything bad to it.

For the anonymity, please understand that, we do that for the safety reason, we'll also provide the best anonymity for our players, that's why there's an onion address for the site.

To build the reputation takes a long time, and we're prepared to do it anyway. :)

I suggest the following: Sam.Walton why don't you provide your personal information directly to dooglus? I understand that you wouldn't want too (and you have absolutely no obligation to do so), however this would improve community trust in you ten fold, once dooglus verifies the information. Otherwise, you could involve dooglus somehow (for example having him hold server seeds as he offered with dicebitco.in). Once again, you have no obligation to do any of the above.

Thanks for the suggestion marco. We will explore these ideas as well :)

But how is dooglus going to verify the personal information?
Also IMHO, knowing the site owner's identity won't help much in gaining trust, as knowing who Mark Karpeles is doesn't help recovering ones' mtgox fund...

On the other hand, having doog control (or co-control) the server seeds and cold wallet could work IMO.

Had we not known Mark Karpeles' information matters would be much, much worse.

Yet that defeats the purpose of gaining trust or even setting up a gambling site if a reputable member comes in and pretty much takes over (sever seeds and cold wallet funds are the things which show ownership and control). Actually, involving dooglus just makes him run another gambling site, instead of Sam.Walton runnning a new one.

Agree. But what I want to say is that knowing the owners' info may help a bit in gaining trust, but the effect won't be enough IMO.



Yup you are right. Maybe you could even call the site JD 2 then.

I guess it depends on what OP wants.
If he wants to make himself and his site trusted, it will be a slow and costly process.
If he simply wants to make his site trusted and earn some bitcoin through running it, partnering with a trusted bitcoiner (and sharing part of the site profit) could be a much easier and faster way to do it.

Why is doog not replying safedice's messages?

Exactly, that will be the options that we are considering, another option is to run the site with our own fund as bankroll (but of course we'll have to find another source of fund :D, which is challenging as well).

We are pretty much open for certain possibilities at the moment.. Lets see how this will go. This is very exciting moment for SafeDice. Also, whichever decision will we take, we will need to improve the site features and usability, so that will be our focus in parallel.


Messages? Do you mean in this thread?

I have withdraw 0.1788 but site wa laggy did not withdraw for me, then i played again and withdraw 0.1905 and i did not recieve
just recieved 0.1788
please check my account
nick: Azmy

and i think there is a bug, you said max profit 0.05.
i bet 0.0001 x 980 and wont almost 0.097 btc

check

i dont think thats a bug, since you can aim for a higher max profit if youre willing to deal with a increasing house edge.

at least thats the way I understood the explanation in this thread somehwere above.

Hey Azmy, finally, congratulation for the winning!  :)
I'm confused with your statement, but I guess you already received your withdrawal? Your 0.1905 withdrawal was not being processed because actually the previous withdrawal had been processed immediately and you don't have enough balance for the second withdrawal (here is your 0.1788 withdrawal tx log http://btc.blockr.io/tx/info/30573f90c7c5240c66b2d4a20c9c1d4b080e1e3e8b74a19a4be676a4edf758d7)


Yes, exactly. You should also able to check the H.E. that is being used on the bottom of the betting box.

I had enought balance, i had 0.1788 and then withdraw but could not withdraw so i played and won more 0.02 and then withdraw 0.19 but did not recieve also, just recieved the first one.
I just saying because there is a lag or bug which caused that and i need you to fix it, i do not need anything else.
Just advice :)
I like the site anyway

I think that's only a connection problem, everything is ok in our log.
Ok then, as long as you already received your 0.1788.
We will keep an eye on this, don't hesitate to let us know when you encounter this again.

By the way, here's a screenshot of our recent works (not published yet), a variable house edge that can change depends on the 'profit on win'!

http://s26.postimg.org/gpw00oikp/vhe.jpg (http://postimage.org/)

And yes that's a roll with 0.64273389% H.E. :D

Is dooglus verifying users? I mean if he proof the existence of a user, everyone is believing him but the user is a scammer, wouldn't he get all the shitstorm?

I think it wouldn't be good for his reputation.

I'll take a look later today, hopefully.


I'm not doing anything. I played on the site a little and posted some feedback. That's all.

There is no way for doog, or I, or any other person (escrow or otherwise) to verify and authenticate IDs without connections to the government of the country where that ID came from.

Show me a passport, then I would need to have it checked with the local embassy or consul. Show me a driver's license, then I would need to call the transport authority or agency that issued it.

There are some people who do this for a living.

For example, I am currently holding some Euro identification cards of some hardware hosting miners. My google-fu tells me that it all looks legit. But I can not guarantee it. All I can do is release the info if said person disappears. (This particular contract is good for about 6 months.)

Can you do a leaderboard for the top players who waged alot.

Yeah, I assumed that.

For what purpose? Does the site have affilitiate program like Win88 too?

So, a bet with lower "profit on win" will have a lower house edge, and vice versa? That would make your site very attractive to smaller gamblers with the lower edge. :)

Leaderboard is fun, when we play a multiplayer game, we tend to pursue the number one ranking didn't we? :D. Currently we are focusing on the development of variable house edge, and then we will focus on functional features and features for our investors first. But additional things like leaderboard is also on our list ;)

Currently we don't have an affiliate program Marykris :)


Exactly!! And still safe for the investors too :)

looks pretty good

What's actually this 1% House Hedge means?
Is there any faucet available in this dice game?

It means that you can expect to get back 99% of everything you risk, long term.

So does it means that if I bet 50 %

Because of 1 % house edge

I got 49% chance for winning that bet ?

Ha, "Long Term" that the real risk behind it.

Yes in the Long Run. But waiting to be in the Long run introduces a lot of higher risks.

No, you have a 50% chance of winning a 50% bet, but when you win, you don't get 2x your bet, you only get 1.98x.

1.98 is 99% of 2

If you bet 1 unit at 50% 2 million times, you will win about a million times, and lose about a million times. Each loss costs you 1 unit. Each win nets you 0.98 units of profit. Your total losses are 1 million. Your total wins are 980 thousand. Your net loss is 20 thousand, and your total amount risked is 2 million. Your net loss (20k) is 1% of your total risked (2 million).

Get it?

Note that as a player, you don't want "the long run", because in the long run you lose 1% of everything you bet.

As a gambler you're hoping for short-term variance to make you win, against expectation.

If you keep playing long enough, you will lose because of the house edge.

Thanks for the awesome explanation.
Now I know the 1% edge risk  :P

Thanks for helping to explain Doog ;)

Nov 19, 2014 - Investment feature will be disabled in the next update
Following our recent discussion with some forum members. We think it is best to close our investment feature until indefinite amount of time. We admit that currently we are still to new for this type of feature and the community just get shocked by the recent cases. Continuing this feature will not only harm our brand, but it might implied that we are insensitive to the recent cases.

• Will you open this feature again?
  We might open the investment feature again in the future when we work with a partner that is trusted both by us and the community, or when we believe we are ready and there are lot of requests of this features.
• I still have investment in my account, what should I do?
  If you still have your investment in your account, you will still be able to use it.
• But will the site be playable?
  We will use our Variable House Edge system, this will allow us to run the site with lower amount of bankroll to a certain limitation. Meanwhile we are looking for a better solution.
• But I really want to invest?
  You will need to contact us privately for this matter.

Someone might have asked this before, but I am wondering this:
Why is the house edge 2% if I want to make a bet of 0.06 @ x2 ?
If I bet 0.15 @x2 the house edge is 3% :o Why is that?

Hope this explains  :)

Yeah, that explains a lot. I didn't read the previous pages.

In the next update the house edge will use a floating number, stay tuned guys :D

you should add faucet

it will attract a lot of people!!!

Thank you for the suggestion pure, but there are also lot of controversy about faucet. Currently we are still trying to attract people with features other than faucet.

What controversy is that?

bot users, PD is having problems with them

This one... :P

Do you guys plan to remove the faucet due to that?

yes they do!!!


it's like your having a few friends over for beers next thing you know theor 70 peeps and all drunk and puke all over house



then crash over night




and they never leave

We have nothing to remove since we never had it 8)


 :D

IMO their bankroll is much too small to support a faucet. The max bet for what their bankroll (~11 BTC currently) can support is only a little bit larger then what faucets would give out. Plus you have the issue of the fact that the bankroll is investor funded

An alternate suggestion would be to allow people to play with "play" money that cannot be withdrawn and is kept track of separately then real bitcoin deposited.

this also a good suggestion because there are dice sites that has no faucet but was able to get supportive members

I found a bug with the site.

I set the payout multiplier to 2, set the stake to 0.01, and started martingaling.

I lost 0.01, lost 0.02, tried to double again (using the 'w' hotkey) but it wouldn't let me bet 0.04.

Pressing 'w' with the stake at 0.02 changed the stake to 0.04 as expected, and changed the chance of winning from 49.75% to 49.662% (that's to be expected, since 0.04 is more than 0.25% of the 11.8 BTC bankroll). When I hit 'h' to roll, nothing happened. I checked the javascript console and saw error messages:

Is there a bug bounty on this site? If so, please credit it to my on-site balance. :)

Edit: I should mention that I tried changing the chance to 50% and then it let me bet - I had to go quite high before I ended up winning. Then I switched back to 2x again, and the bug happened again as soon as I got up to betting 0.04 BTC on a roll - so this wasn't a random site outage - it's very likely to be related to the specific bet I'm trying to make.

Edit2: I won a bit more and withdrew my balance without any trouble. Then I clicked 'history' and noticed that it only showed a single deposit and a single withdrawal, both from a week ago. It should have shown two of each, since I deposited and withdrew today. Reloading the page fixed it, but I shouldn't have to reload to get the history updated.

Edit3: I think the problem is that when the payout multiplier is fixed, and you calculate the chance from it, you're rounding up instead of down, giving a slightly lower house edge than intended, which the server then rejects. When I'm trying to bet 0.04 to win 2x, the chance is set to 49.662%, but if I put 49.662% in the chance box, the payout is a little under 2x. I ended up editing the chance to 49.661%, the payout went a little over 2x, and it let me bet. I suspect you can fix this by rounding down instead of up when calculating the chance from the payout multiplier.

Edit4: The variable house edge feature works pretty well (other than the error I reported above). Here's a screenshot showing how the site got me betting against a 5% house edge - something I would normally never even consider doing. :)

But wouldn't that will be confusing for the player? It's like integrating test server and real server at the same time.

Hi Doog... Thank you for founding those problem!


That's very good observation. It does related to rounding but not exactly because of round down / up problem. It is because the server reject an unavailable payout. Here's our explanation.

• When the user manually set the payout, browser will round the payout to the nearest possible payout (because roll number / win chance is actually a discrete number) after the user is done editing
• With variable H.E. the payout can change in realtime. When the H.E. changed, browser changes the win change according to the user payout.
• However, the payout still remain the same, and those exact payout doesn't always available (remember that roll number is discrete).
• When the user rolls, SD's server check the roll integrity and found that the submitted payout slightly missed, therefore the safety mechanism rejects the roll (our log literally wrote "impossible payout" :D).

We have fixed this issue now, the payout will now change to the nearest possible payout automatically when the H.E. changed.



Done! We don't have a bug bounty program, but may reward it in an ad hoc manner. Many thanks for all the reports and suggestions so far Doog :)


Lol, luckily you won those bet :D
