I like the autoplay feature. Is there a way you can prove that that's not rigged?

I actually just found a bug for the autoplay. I had 8s (dealer had 9) and it split them. I drew a 7 and the game stopped and my browser showed an error message.

Thanks for the bug report! You can look at the JavaScript if you like, or just take a look at the bottom of the page where your play history scrolls by, you can click the VERIFY button next to any row to check the provably fair data.

You might want to go back and check everything out before release, seems to be player friendly and alot of the same hands.
Thanks. The shuffle *should* be truly random. Would you mind PM'ing me your account key? I'd like to check your play history for any patterns in the shuffles. Much appreciated.

Its got a nice feel to it. It has a general look of video blackjack that's played in a Vegas casino. I had a few glitches come up while playing that said my internet connection was lost when I know it wasn't. Overall, after playing some hands, it generally was pretty smooth. I was confused at the beginning with the term "DRAW" rather than "DEAL". I prefer the DEAL wording better. I'm sure after some time you'll get the kinks out. Any BTC would be appreciated! Thanks! 1P1A8ttw9KfPhaVLRjYoczNwqyq8pzuhhv

Thanks, all good reports. I'll get the max bet fixed. Also the bug in the provably fair checker seems to be related to taking insurance. It doesn't seem to be a problem with the game, just the fairness check. I'll get that patched up quickly!

Another issue was the fact that I bet my last 38 credits and won the hand, but when I proceeded to hit the draw button, the "ADD CREDITS" box popped up and would not let me play any further without depositing BTC!

Looks like there's a small logic issue with the dialog. If you refresh your browser, or wait a few seconds, you'll see the credits refresh. Should be an easy fix for us.

Not trying to rip anyone off. We coded this site up while BVC was down hard last week. We honestly weren't sure if they were coming back and aimed to fill the void. I think there's a shortage of good low house edge BTC games out there and I think that's a shame. This is the version 0.1 interface and the frontend was arguably slapped together. We're validating our backend infrastructure right now and trying to push as many games through the system as possible. Our auditor requires 100k unique game histories to certify our system. Don't worry, we're working on quite a few graphical improvements as we speak. But thanks for the good feedback.

So I played this morning. Only error I got was when taking insurance and dealer had bj. Other that that no errors.
I did run the 50 credits to 700+. Cashed out at about 650 (.65btc.)
Instant cashout, and looks just like the video bj at the bar of casinos I've been in. I like it!
Ill be playing more later.

We honestly weren't sure if they were coming back and aimed to fill the void. maybe if you looked at their thread, you wouldn't have doubts: Hi Cogine,
We are still having trouble with our hosting provider. All accounts and Bitcoins are safe. We are trying our best to get this resolved as quickly as possible. We are really sorry that the site has been down for so long.
We're validating our backend infrastructure right now and trying to push as many games through the system as possible. Our auditor requires 100k unique game histories to certify our system.
do you really need that? Don't worry, we're working on quite a few graphical improvements as we speak.
You really should had started with this done.

Ok I just played the bitcoin portion of the game. Thanks for the test account My Review:
Everything seems fair the hashes and results are displayed on the bottom instantly after each round. Blackjack pays the usual and the plus side is dealer stays on soft 17 (giving the player more of an advantage). Like I said before graphics look nice and site loads quick. Great job and Good luck with your website!

20% on any and all first deposit ? Instant withdraw or some certain amount of games played is required ? Take care there.

As a thank you to the bitcointalk community, we're offering a 20% deposit bonus on all first time deposits. Just PM me your account once you make your first deposit and I'll apply the bonus!
20% on any and all first deposit ? Instant withdraw or some certain amount of games played is required ? Take care there. Good question: The promotion is currently listed as 20% on initial deposits. Initial deposit can be withdrawn instantly, the bonus 20% can be withdrawn after 20x play. Thanks for asking, I realized that wasn't listed on the original post.

Critical bug found, sites bankroll at risk ( not player bankrolls). Advised owners to callme so I can describe. I'd hope they will offer a bounty also. I literally could have taken whole site backroll. Please call or message asap.

Great catch. Appreciate that you reported this ethically. We confirmed that there was a bug that could in some cases cause a deposit to be credited more than once to an account. We have patched it and can verify that player funds were at no time at risk. Your bounty will be on its way!

Is that proprietary software? Honestly had much better cards playing with this casino then bitcoinvideocasino. Wonder if there is an "on" and "off" switch for winning hands.

Well, it is clearly copyright infringement, which is of course illegal. The chance they will take legal actions is obviously nill, but that doesn't make it ok.

If you look at the JavaScript you'll see that your browser hashes the raw server seed we send at the end of the game and compares it to the hash of the server seed we sent before the game. If the two don't match an error is thrown. Can you send me the gameid of a game where you don't think the hash matches? I'd like to investigate.

Another issue:
You charge .0005 on withdraws to cover miners fees....but you are sending out withdraws with only a .0001 miners fee, which is making all the withdraws take ages.....
I have withdrawn 3 times now, with this happening, and still have a little funds to withdraw when done. So I have already paid .012 in fees that didn't go to the miners, and prolonged confirmations. Can this get fixed? Not too concerned about getting the funds back, more concerned that if I am having .005 deducted from my withdraws, I want it applied to the miners fee, so that I am not waiting hours to get a confirmation on the network.

I'm sorry about that, I'm looking into why that transaction didn't post. I see the transaction though. I've refunded the deposit to your address above, I would recommend trying a new account just to be safe.

It looks like our deposit queue got a little backed up (a good problem to have I guess), the transaction finally processed and there was nothing wrong with your account so you can keep using the same one. We've added another worker to our deposit process and the queue is back down to zero. Transactions should be posting instantly again. Sorry for the hassle with the long deposit delays!

We're flattered that you thought our casino was great enough to copy.
That being said, we always recommend that the community be diligent about the casinos they play on. We found that your stated return to player is 99.6%, but with the BJ rules we used (which you didn't change) the return to player is 99.5%. Our 99.6% comes from a .1% contribution to the progressive jackpot. You have no progressive jackpot, so where is that extra .1% going?
We also tried playing on your site but the deposit was never credited.

Thanks, our payout percentage was calculated using the wizard of odds calculator which gives us a house edge of 0.42945% which is technically 99.57055% We rounded to 99.6, but it's a good point. The site has already been updated to be more accurate. As for the deposit, let me know the BTC address and I'll investigate. We use the blockchain.info API to verify confirmations. There's been some weird problems with their service over the last 24 hours and we've seen a few transactions that aren't showing as confirmed even though they are. We're going to be manually watching the queue until blockchain.info gets sorted out.

Again tried to play and deposit and this is 2nd issue on deposit and had an issue on withdrawling. Please fix this and make a post here to stay to stop crediting until its done. https://blockchain.info/address/18b5S1sZbBwpbEDouHAzQBqy464PBYNNt7I dont want this manually credited to my balance I want it paid back through blockchain I am will be leaving in next 30 minutes. Please deposit here. 13brby3sxQstqdjyZSZjxgxkaDfW2KCARs Refunded. We just stopped using the blockchain.info API to confirm transactions until whatever is wrong with their system is fixed. If anyone else feels that a deposit hasn't credited, please drop me a note and I'll get it resolved. Thanks!

We have performed an analysis of the provably fair code on DoubleDownBTC and believe that it is not legitimate. There is absolutely no guarantee that the shuffle generated is random, so they could be packing the deck in their favor.
Using the values from the provably fair dialog, when we try to manually generate the deck given the game seed, we get a different deck of cards. This means that on the server side it is not actually using this verification data. We suspect that the server is not following the rules of provably fair and is shuffling the deck however it wants.
GameID: 523d3d4915413651609f8cbf Game Seed == Server Seed + Client Seed: 14593047563445106624089340932 Mersenne(Game Seed) == Final shuffled deck (first 52 cards): kd8hjhah4d3c9c6h9hkskcjc7djdah7sahtdtc8c3hjd4skh2c2d
Can you please demonstrate how you were able to generate that deck of cards given that game seed?
The client-side Javascript function that verifies the deck shuffle has been purposely disabled. The function is called check_game(), and it is supposed to check that the deck that was actually played is the same as what the server committed to when it initially sent the server seed. However, after this function shuffles the deck, it then just cheats and manually sets the generated deck of cards to what the server dealt:
var game_cards = game_info_package.deal_hash_source.slice(1, first_close_paren); check_cards_string = game_cards; if (check_cards_string == game_cards) { proves_deck = true;
Essentially the code is generating the deck, but then setting check_cards_string to equal game_cards, so that the test will always pass. This means that the verify dialog will falsely tell you that the shuffle was legitimate, when it in fact was not.
To summarize, the server is not shuffling the deck in a provably fair way. The client code has been purposely disabled to not point out this error. Please be careful. We don’t want people getting scammed betting with their Bitcoins, especially on a site that looks almost identical to Bitcoin Video Casino.

Excellent catch. Thanks for reporting that. You are correct, the check logic in the JS is disabled, this seems to be a missed relic from testing. The code is being corrected today. As for how we calculate the deck from the game seed: It's pretty straight forward We take the final game seed + the game seed hash, convert this to a string (which is a byte stream in PHP) and use it as the seed for the mt_srand function in PHP. This will seed the Mersenne Twister algorithm. We then perform a Fisher Yates shuffle on the shuffled deck, using the mt_rand function as the RNG. This adds two levels of randomness to the shuffle and provides a reproducible result after the fact. In the essence of transparency we've decided to add a feature to the site which will allow anyone to download a public game history file each day which will show all games played, the server, client and game seed as well as the complete shuffled deck. This can be used to perform analysis on the dataset, or simply to verify a particular game again after the fact. We are also in the processes of having our game engine externally audited which will add a further level of trust to our engine. While I am happy that a developer let this test get into production, I can assure you that the games are random. Anyone that has a particular concern about the outcome of a game or the randomness of a shuffle, please contact any of us directly and we will provide the complete audit history of any game. Thanks again for the great bug catch.

We find it hilarious that you speak of "a further level of trust" when you have blatantly stolen our HTML, CSS, Javascript, art and sound files, and claim provably fair blackjack yet actually have no such thing. The fact that you think any of this is OK is mind boggling.
We have worked hard to create a casino that is trustworthy and fun to play. We will continue to improve our site, and we hope that in the end, users will know which web sites they can trust their Bitcoins with.

I'm really concerned that you keep having these issues. I've investigated the transaction and it doesn't look like it's been picked up by Coinbase yet. The transaction you referenced is in block 260089, but coinbase, who we have been using as a temporary deposit processor since last weekend, is only reporting up to block 260029. There seems to be a serious lag right now. We moved to coinbase temporarily as a way to expedite deposits and confirmation verifications, this seems to be causing different issues. Our developer is investigating an option to use our previous bitcoind solution. It doesn't look like there is a reliable thirdparty processor yet unfortunately.

We have a ticket open with Coinbase, there are multiple transactions held up with them right now. We cannot cancel the transaction at this point because it's already been accepted, We can process any future cashouts manually until Coinbase gets back in sync with the rest of the blockchain.

Future cashouts doesn't help that I've got my last .75 btc in limbo. This isn't a new issue, coinbase made a post about it yesterday, yet you still are sending cashouts their way. This is new....previously they were all instant. Figures, the time I make a largish deposit and withdraw, therws issues holding it up for hours. If I don't have my btc in next 2 hours and I miss some vets on games I want to put in, I'm going to be very pissed off .
