Bitcoin Forum

luckco.in (https://luckco.in) will be shutting down by the end of April. Withdraws are still possible.

I had a couple of issues right after signing up.

The first hand I played showed me my 5 cards.  I clicked 2 of them (a pair I wanted to hold) then before I did anything else, all 5 cards turned face down, as if the hand was over.

The second hand I played popped up an error message in the bottom right of the screen.  It disappeared before I could screenshot it, but it said something about being unable to call method 'push' or something or other.

After that the game seemed to lock up.  I could type into the chat box, but my messages weren't displayed.

I reloaded the webpage, and since then everything worked fine.  I even hit a full house at one point, but eventually ran out of free chips.

The game itself runs pretty well once it's working.  I think I'd like to see 'DEAL' change to 'REDEAL' or some such different word to make it clear whether I'm on my 1st or 2nd deal.

Provable fairness is notably lacking and is a feature that lots of bitcoin casinos are implementing these days.  The ability to prove that you're dealing a fair game is attractive.

I'd like to be able to set my name in the chat rather than the auto-generated name it's using for me.

That's about all for now though.  Thanks for the free chips.  The quiz is a nice touch to keep people on the site.

I notice the deposit popup says:


These 'some minutes' - are you waiting for a confirmation?  It would be nice if you were more explicit about what the delay is for, whether you accept 0-confirmation deposits but don't allow withdrawals until they're confirmed, etc.

I got a good hand, like two aces, and some other pair, for double pair, and immediately it played out without holding the cards.
And I lost 5 credits :/

Well some reworking is needed

Was that the first time you played after signing up?  That's the only time I've had a problem like that in the 128 hands I've played.

I like the quizzes every 10 minutes to let players win 10 free chips.  I like the live chat and alerts about people's wins.

I like it when I hit 4 of a kind...  :)

Edit: even better!

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

When I hit withdraw, it assumes I want to withdraw as much as possible.  That might not be the case.


It would be better if it asked for an amount as well as an address.  Have it tell me how much is available, but let me type a number up to that amount.

I got 10 chips for signing up and saying 'welcome bonus' or similar in the chat.

Then I lost it all before managing to bet the 10x wagering requirement.

Then I won another 10 chips in a quiz, and found that my wagering requirement was now at 168 or something.

I think when my balance reaches zero any old wagering requirement should be cleared.  Otherwise I'm better off just making a new account.  An old account with zero balance but positive wagering requirement is worth less than nothing...

I managed to clear my WR and withdraw more than I deposited, so I'm happy anyway, but thought I should mention the above.  :)

I don't see how.  I can already effectively reset it by making a new account.

Nah, it was about the 10th hand or so.

I just had a game freeze up on me.

I had been offline for a few hours, then got back online, clicked 'deal', got a couple of queens, held the two queens, clicked 'deal' again, and saw an error box pop up in the bottom right.  It was too quick for me to screenshot it, but here's how the screen looked after it had gone.  I tried talking in the chat box, but my message didn't go through:

https://i.imgur.com/ds9aZ.png

Then, while I was typing this message, the screen updated to look like this:

https://i.imgur.com/N2DzP.png

I didn't get to see my new hand, but judging by the balance it looks like I got a 3rd queen.  The "THREE OF A KIND" line isn't white like it would normally be after a win though, so I don't know what happened.  I think that's my name it is welcoming in the chat, so maybe it thinks I only just joined, whereas really I've already played a game before the welcome message showed up.  And it's not normal to see the 'backs' of cards except before your first game.

I got the error message again.  Again it was on the first hand after I'd taken a break for an hour or two, and again it was after I had decided which cards to hold, and clicked 'deal' for the 2nd time.

This time I was quick enough to grab a screenshot:

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

I got this error too, once.

Here's a weird one:

https://i.imgur.com/bBn9b.png

I got it right on my very first guess, but it wasn't picked up.

The other guy in the chat saw it though, and commented on it:

https://i.imgur.com/1lVv7.png

Wow, you're the guy who wasted my time by hiding from irc after we agreed to a deal.

Are you talking to me?  If so I can't imagine what deal you're talking about.  I sometimes try to buy BTC for PayPal on #bitcoin-otc but recently have had very little luck.  Unsurprisingly, I guess.

There's a display bug that seems pretty reproducible.

I play for 3 chips per hand.  If I get a straight on the first deal and hold all 5 cards, it adds 5*4 to my balance, then takes off 2*4.

For example, I had 109 chips after starting the hand.  I held all 5 cards, hit deal, and saw my balance update to 129 and then after half a second or so update again to 121.

I've noticed this happen at least 3 times now.  I think maybe it only happens when I've held all 5 cards.

I just discovered a bug in the withdraw code.  I had a balance of ~160, and a Wagering Requirement of 60.  I clicked 'withdraw' and then 'withdraw' again without putting in a bitcoin address.

It took 100 (or so) chips off my balance leaving me with 60, but didn't (of course) send me the other 100.

The game operator was online at the time so I reported the issue to him there.  He's unable to fix it at the moment, so he's taken the game down until he can:

https://i.imgur.com/31Xzw.png

There was an issue with withdrawing BTC to invalid/empty addresses. The fix (https://github.com/abrkn/joggy/commit/2e21cbd7f5617f350bbc9ba1af8c6754fc84cb81) is live

Tradefortress, I've looked over the IRC logs and it seems we are on very different time zones when you've tried to reach me. E-mail me at any time, a@abrkn.com.

I found the bug immediately after you mentioned it and have corrected it. In summary, any attempt to withdraw money to an invalid bitcoin address would simply take the funds from you.

Please PM or e-mail me a bitcoin address for immediate reimbursement (your 10 credit welcome bonus has also been reset and can be claimed the next time you log on)

I used http://wizardofodds.com/games/video-poker/analyzer/ to work out how big the jackpot has to be before the game is +EV for the player:

https://i.imgur.com/nmj0s.png

Seems to be around 4880.

Thanks for the analysis. It should be noted that with the quizzes and bonuses available, play.luckco.in is potentially +EV anyway, even with a 4000-credit (BTC4) jackpot.

I keyed in the payout table for Bitcoin Video Poker (flush paying 4:1 instead of 5:1, jackpot 4000) and the rake comes out at 1,6%.

Where's "Bitcoin Video Poker", with a lower flush payout?

I thought this play.luckco.in had the standard flush payout.  (It's currently down, so I can't check).

http://bitcoinvideopoker.com/

Slick interface, but yeah, it's got more rake, no prog jackpot and no quizzes for free moolah.


play.luckco.in is "full pay, nine-six" jacks or better, yes.

Thanks.  I'd somehow managed to miss that one.

Good news, then: play to win!

I am nearly done with the next slot, which is called "Red, White & Blue", originally designed by IGT.

The problem is that the slot is very greedy! It only pays you back 87.45% of your bet. I would rather that you get paid back 98%, 1% goes toward the progressive jackpot and 1% goes to the casino. What do you think?

Please submit your paytable suggestions here (http://jsfiddle.net/abrkn/eSp2D/)

Original slot looks like this: http://www.youtube.com/watch?v=BmcmirGdXok (http://www.youtube.com/watch?v=BmcmirGdXok)

When you save (CTRL-S), you get a new URL in the address bar that you can show us. Try to get as close to 0.98 as you can!

This is my best matching pay table so far: http://jsfiddle.net/abrkn/eSp2D/3/

The Red, White & Blue slot is now published at http://play.luckco.in/ (http://play.luckco.in/)

It returns 98%, I will add a progressive jackpot to it soon.

Good luck!

Internet Explorer is now supported (v9+)

https://i.imgur.com/g9cYY.png (http://play.luckco.in)

For what it's worth, we've updated the pay schedule to be full 9-6.  We're working on doing some kind of progressive jackpot, too.

Glad to see more VP fans, wouldnt it be cool with an inter site mega jackpot?

Id like to remind you that our VP is currently at positive value, meaning the player has advantage over the house! May the best coiner win

Note that you have to play the max bet of 5 mBTC per hand to have a positive expectation.

The video poker graphics have been completely overhauled, addressing every issue raised by our players.

Let the race for the jackpot (currently 5.3 BTC) continue!

If you need any help, e-mail to hello@luckco.in or post an issue (https://github.com/abrkn/joggy/issues)

I just went to log in, but it picked the wrong google account.  When I said I didn't want to share information about the account I was logged in as, I saw an ugly error page.  You should probably handle this case better:

https://i.imgur.com/y1hJm.png

Issue added (#26) (https://github.com/abrkn/joggy/issues/26), thank you

2 more issues:

1) When I win, my balance goes up before the re-drawn cards are revealed.  This seems backwards.  You should show the re-drawn cards and then, if I win, update the balance.  Otherwise it kind of breaks the tension.

2) I had 13 chips, and was betting 1 coin per hand.  I clicked 'bet one' 5 times, causing the red bar to cycle around and end up back on the first column.  Then I clicked 'deal' and my balance went down by 6 to 7 chips.  I didn't get to finish the hand because "backed updated; refreshing" or some such, and now I can't get the poker to show up at all.

Try this:

Play for one chip per hand, but click 'bet one' 5 times each hand before clicking 'deal'.

Watch your balance closely.

I just had a hand where after clicking 'bet one' 5 times and clicking deal, it took off 2 chips.  I got 3 of a kind, and was paid out 6 chips, not 3.  The display says "win 3".  Is it possible that the backend thinks I played for 2 chips but the frontend thinks I played for 1?  Maybe some of my 5 quick clicks on 'bet one' are being missed by the server.

I'll see if I can get some screenshot evidence...

This isn't quite what I was aiming for, but it does indicate a problem:

I won my last hand, and ended up with 33 credits:

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

I didn't click any 'bet' buttons, just clicked 'deal', but it took 3 chips off me anyway leaving 30 chips

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

I held the 2 pairs:

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

and hit a full house, and my balance went to 47 (up 17!) even though the chat said I won 9:

https://i.imgur.com/ZqaV0.png

then I reloaded the game and see that I really have 39 chips:

https://i.imgur.com/3mwLS.png

So it really did take 3 off me to play, and paid out 9?

After the update, I no longer see that issue.  But I see a different one:

I have 32 credits before playing:

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

I play for 1 credit reducing balance to 31, and get a bunch of crappy cards:

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

I re-deal them all, getting a win, but my balance stays at 31:

https://i.imgur.com/E59bY.png

I reload the game, and see my balance is really 32:

https://i.imgur.com/E1Vqm.png

Someone was complaining that the game uses 100% CPU on firefox, so I ran firefox to see.  It uses about 50% of one CPU core for me, with another 75% of the other core being used by the X server, so it is indeed pretty heavy.  Chromium is similar, using another 50%.

Anyway, it turned out that I was logged on as DrLex67 in firefox, and she was playing already from wherever she is at the moment.  I could see the initial 5 cards each time she hit deal, but I never got to see what cards she was holding, and never got to see the re-dealt cards.

I've seen you write somewhere that the game is meant to work across multiple devices, so I guess this is a bug that needs fixing.

Great site, I play at the blackjack/roulette, seems fair! :D

Wrong thread?  There's only video poker and slots.

I see that's fixed now, but you're still giving the game away early by posting about big wins in the chat before the cards are revealed...

More generally:

When I win, my balance updates by one less than it should, and when I play the next hand, my balance isn't updated at all.  My balance is updated when I lose a hand, or if I reload the game.

So if I lose a game then win one (always playing for 5 chips per hand), my displayed balance is 1 less than my true balance.

If I then win the next game, my displayed balance is 3 more than it should be (two single chips from my 2 wins weren't added, and one set of 5 chips weren't deducted).

If I continue winning, my displayed balance is 7, 11, 15, 19, etc. chips too high.  Each win gives me one less chip than it should, but the next game costs 5 chips less than it should, giving a net gain of 4 chips per hand.

Here's a screenshot after I won 6 hands in a row, so my displayed balance is 19 more than my real balance (my real balance can be found in the 'withdraw' dialog at any time, btw):

https://i.imgur.com/6KVko.png

Close:

But no cigar:

I'm still trying to win that jackpot.  Here's the closest I came so far today:

Edit: running out of chips:

https://i.imgur.com/3Bp3O.png

New bugs:

1) when I win a quiz my balance doesn't update until I lose a hand (I think) or refresh the game.  It used to refresh as soon as I won.

2) I had a funny hand.  I held one card, clicked 'deal', the other 4 turned face down and then nothing happened.  I can still select which cards to hold - here I've selected a couple of the face-down cards to hold...

https://i.imgur.com/eRIF1.png

I made a deposit but the coins never showed up in my account.

See report here: https://bitcointalk.org/index.php?topic=128969.msg1400320#msg1400320

Nice addition :)

This time I held nothing:

I've seen like 10 of these screenshots now... 42 to go? ;-)

I'm so sick of video poker now...  :)

The website seems to be down?

Which URL are you using? The correct URL is https://luckco.in (https://luckco.in)

There's a new type of contest:

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

The objective of this game is to click the correct picture as close to zero as you can. Get the lowest time of everyone in the chat and sprinkles will give you a prize.

Emoticons!

https://i.imgur.com/sbW4P.png

sprinkles just told me to 'lookup now' but there was nothing to see:

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

The first time she said to 'look up', there was a click-the-picture game, but the 2nd time there wasn't.

It seems that the quizzes are just broken now.  Sprinkles keeps announcing them, but they never happen.  I tried reloading the page but it doesn't help.

Typo.

It's working again now:

User MrBob832 seems really suspicious, some kind of bot capable of auto-answering Sprinkles's questions very quickly. This needs some investigation.

Thanks, it must've been a problem on my end, I was getting 503 errors, https ended up fixing the problem.

I thought this had been fixed already, but maybe not.

I won a quiz, but my balance didn't update:

https://i.imgur.com/z2Mzc.png

Recorded as bug (https://github.com/abrkn/joggy/issues/70), thank you

The guy in spot 6 hit hard 20 and got an ace!  It's almost as if he had noticed the deck wasn't shuffled.  ;)

I was dealt 4 to a royal.  I don't think I've seen that before:

https://i.imgur.com/IW4Vu.png

According to http://wizardofodds.com/games/video-poker/analyzer/ the 5-coin game now has a house edge of -0.5544% (yes, it's negative).  And that's not including the 0.45% or whatever it is that goes into the progressive pot.

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

I reported two (https://github.com/abrkn/joggy/issues/73) new bugs (https://github.com/abrkn/joggy/issues/74) in the issue tracker.

I'll use that in future rather than posting here if that's OK with you.

Thought I had it for a second here:

https://i.imgur.com/v6A1S.png

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

This deal was close:

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

but not close enough:

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

So it's going to be 1 more than half the time, right?

https://i.imgur.com/8FJhQ.png

I think it would be better if sprinkles:

* called it "1 CREDIT" (singular) when it's 1 credit
* mentioned that it was random in some way
* said that the bonus would be reset soon so "come back tomorrow" or similar

The jackpot is up to almost 6000 chips now!

You should fix this:

typing luckco.in loads ok but typing www.luckco.in the site can't be found.

I reported this here: https://github.com/abrkn/joggy/issues/79

tks man, didn't know that it is a open source project

I've not looked at the source enough to tell whether there's enough in the public git repo to allow anyone else to set up a copy of the site or not.  That would be cool though.  And if so, the thread topic should be change to include 'open source'.  :)

using Google accounts might be a bad idea - I have google apps and I can easily create 50 google accounts..

It's not like any other system restricts users from making multiple accounts, unless you start insisting on getting cell phone numbers from them or some such.

This is the closest I've come so far to the jackpot:

I hope you wait for confirmations before allowing withdrawals.

Otherwise I can double-spend a deposit to you and withdraw clean coins.

Yes, just disallow withdrawals from any account with unconfirmed deposits.

So close :( never been dealt JQKA same suit on first deal before.
http://s13.postimage.org/tnpitdyit/close.png

I've only seen that once and I've played thousands of hands trying to win the jackpot.

Be aware that you only get the jackpot if you're playing for 5 chips per hand by the way...

The jackpot was won at last!

https://i.imgur.com/mcVx6.png

Here's a screenshot from the winner of the jackpot:

A few bonus chips for referrals would be nice.

I think it's a good idea, but I don't know how you would afford to pay it given that your games already have such a tiny (often negative) edge anyway.

I don't think it can.  There's no way you can tell whether the people I'm referring are real friends and not just new accounts I made myself.

I've been on the wrong end of this before, referring friends in good faith and being accused of being a liar (https://bitcointalk.org/index.php?topic=91587.msg1019717#msg1019717) as a result.  I referred 2 or 3 people, encouraged them to make deposits, and got myself banned as a result because the site operator thought the people were all just copies of myself.  I guess it's a tough call trying to decide who's legit and who isn't, and it's easy to get it wrong.  But it looks bad when you do.

I tried working out the payout of the red-white-blue slot.  I was curious about whether the large (16k) jackpot made it +EV to play or not.

According to my calculations it doesn't.  It looks to me like the pot needs to be around 23100 chips before it's +EV to play.

Is that right?

The code I wrote to calculate the payout is at http://pastie.org/5624193 but I'm not sure it's right.  It calculates the payout as 98.09% for the standard jackpot of 8100, which is pretty close to what has been written in this thread above:


As you can see, each 8k in the pot adds about 1% to the payout, so an extra 16k is needed to bring the payout up to 100%, making a total pot of around 24k.

I just clicked the 'kitty' game and saw 'too late' as my time, even though I thought I clicked in time.

Then I saw the chat.  It told me (three times) that I won:

I've seen something similar, thanks for reporting. (Restarting game now to see if that will fix it temporarily)

I thought I remembered you telling us that the red-white-blue slot was +EV with the current jackpot size, but can't find it anywhere now.  I guess it must have been in the in-game chat.  Either that or I imagined it.

Odd.  The chat seems to work, but clicking the games results in nothing.

I turned off AdBlock in the domain, so it doesn't seem to be that.

Using Chrome.

The wizard of odds page has the exact same number of possibilities per outcome as I calculated, so I guess my analysis was correct, and that the pot has to be around 23100 before the game is +EV.

It looks like the site has been down for a while: http://www.downforeveryoneorjustme.com/luckco.in (http://www.downforeveryoneorjustme.com/luckco.in)

I had problems registering, and in the end ended up not registering. Every time I clicked a link, it would take me to a google sign -page, and ask me to release details to you. I eventually did agree, but even when I did, I tried clicking a link and it took me through the same process. Each page was taking about 45 seconds to load as well, and the chat box didn't work for me. I just wanted to let you in on these bugs I found.

The blackjack works pretty well for me.

The 'double' button has the 'e' on a different line than the 'doubl'.  (See picture at end of post).

It would be good if hands were logged in the chat maybe.  Sometimes I didn't notice what the result of a hand was in time, and there's no way of looking back.

I've not been able to play multi-player.  My colleague tried to play but "you already received your welcome bonus" (presumably because she has the same IP address as me).

It feels kind of slow.  But that may be because of my 700 ms ping times.  (I'm in Canada, not the US).

I'm only allowed to play one seat at a time.  I can't find a way of leaving my seat.

I tried restarting browsers, switching to Firefox from Safari (I'm on a Mac), and refreshing the page. Every link I clicked it would automatically take me to the Google page where it asked for permission. The games included, and the chat box wasn't working. I'm running Mac OSX 10.5.8, and my primary internet connection is relatively fast. It seems the only time it's slow is when I'm browsing sites like Wal-Mart, Best Buy, and those kind of sites. I failed to create an account, but I'll try again in a few days to see if I can replicate the errors. It might of just been a busy server or something, I'm willing to try again if you need me to.

I just played a few hands.  An error popped up in the bottom right corner.  I rushed to screenshot it before it disappeared but was too slow.  I didn't even get to read it.

After it had gone, the console showed this:

https://i.imgur.com/2cH84.png

I've added a lot of changes today, including:
- Chip stacks indicate if you win or lose. The positioning is not great yet
- Fixes to win/lose/push settlement on both server and client (display)
- Dealer no longer hits soft 17
- Multiple tables
- Blackjack buttons for the games menu (there are two tables, bj1 and bj2)

Looks like the login feature isn't working right now. Tried with different browsers and accounts.

Back up! There were some problems with the database ISP while I was sleeping.

Back down. Looks like a problem with the webserver this time.

Back up!

down again

Thanks for telling! I'm on vacation and will try to find the cause of the downtime once I sober up.

thanks, site's back, but can't withdraw. when i try i get ECONNREFUSED error. does bitcoin server need to be restarted?

restarted! not sure why it doesn't do that auto, will check it out

needs to be restarted again

I'm finally at a place with wifi now so I can figure this out (non-functional upstart scripts)

Doesn't look like it ever got restarted. Still getting ECONNREFUSED.

Haven't been able to withdraw for 4 days, and now the website is down, so can't even play.

I've been traveling around Asia (yay) and not had time to look at the cause. The disk is simply full on the Bitcoin server, I'm working on expanding it now.

Problems solved (added a lot of disk space for the block chain) and re-started the website

can't log in to site. i think i visited site a long while back, so i cleared my cookies, grabbed a different ip by using a different wifi, created a new google account, and authorized luckco.in for that google account. but it still refuses to allow me to log in.

I just tried logging in for the first time in a few weeks and it worked for me.  I used a google account that I had used with the site before.

Please send to help@luckco.in. Any screenshots?

so maybe it's just not allowing new users to create accounts. the frustrating thing is that it doesn't bother to give any error message when it happens, so i can't provide any useful information to help track this down.

I added the following to the github ticket, but it doesn't allow users to reopen tickets, so not sure if you'll see it there:

Before attaching my Google account, I was able to see the games. Now that my Google account is attached, it only shows the chat on the left side, but it doesn't look like the games are showing up. I even disabled my Adblock. Any idea as to what's going on? I've been looking for a bitcoin slot machine for a LONG time now.

can you try the site in another web browser, such as google chrome? please e-mail help@luckco.in if this doesn't work, so i can follow up

the support ticket system lost some e-mails. if you sent to help@luckco.in and did not get a reply, please re-send now

Can you please update us on the withdrawal issue. I added a comment on the github ticket and also included the comment a few posts back.

Found & fixed (just withdraw 10 credits successfully)

how do we know that the games are fair ?   :-\

Don't get me wrong, I'm not saying the games aren't fair, but I think you will attract more players by proving the fairness of every hand played, like bitzino and bitcoinvideocasino do.

Isn't it possible to implant such a system on luckco.in ?

When I talked to the site's owner about this he seemed to be of the opinion that being provably fair doesn't help when the casino owner is in control of your coins.  Look at bitjack21 for instance.  That is/was provably fair, but there are many users claiming that the site owner has refused to pay them their winnings.

I'd argue that at least those users know for sure that they're being cheated, as opposed to people playing on a not-provably-fair site that always honours withdraw requests, but where the house always seems to win when you raise your stake.

Okay, when the admin controls your coins, you'll always have a risk of not being paid, I agree on that.
But on the other side, a casino owner can only benefit from prooving that his games are fair, it can only turn out positive for him (if the games are indeed fair)

And I think most players agree with me when I say I have a better feeling when depositing at a casino that gives proof of fairness , then when I deposit at a casino where is only written that the games are fair, but without any proof

So I don't understand why not all bitcoin casinos prove the fairness of the games like on bitzino, if they can only attract more players by doing this.

Correct me if I'm wrong about this  :)

You can still prove that the games I play are fair.  That way I can be sure I'm getting at least the expected 99.5% payout in the long run (or whatever it is) even if you are cheating on the progressive pot.  Otherwise it's possible you're deliberately withholding half the straight flushes I should be getting.

I guess my question really is why you're resistant to offering 'provably fair' games even if they don't give a 100% guarantee of fairness.

To all the folks asking for "provably fair", can you name a single other gambling site that lets you look at the source? You can prove its fair int he code and, if you think it isn't, provide a patch to fix it. And, if that doesn't float your boat, you can take the code and launch your own site! IMO, open source >>>>>>> "probably fair" because of the possibilities it makes available.

Not that I think abrkn is cheating, but there's no proof that the source code that we can see is the same as the code running on the website.  He could be maintaining a branch that he doesn't push to the public repository, and which cheats somehow.

+1. There is really no excuse for not provably fair.

As reported in the newbie forum, the site's wallet is currently empty: https://bitcointalk.org/index.php?topic=128969.msg1579399#msg1579399 (https://bitcointalk.org/index.php?topic=128969.msg1579399#msg1579399)
