If the tx doesn't show on the site straight away (or even within 10 minutes), do you have some script that will go back and make sure you processed everything?

Still waiting for mine.

Absolutely. The promotion script doesn't appear to have kicked in either at this moment, and it may have been held for processing. Sorry for the delay. I will be in touch...

Announcing 3 Card Poker at DiceOnCrack.com!

Instead of bouncing dice off the blockchain, you can bounce cards! Each transaction is mingled with the secret of the day to produce a provably fair shuffled deck, using a hash based Fisher-Yates shuffle algorithm. You are given the top 3 cards, and that hand is then ranked. Payouts:
Royal Flush: 50 to 1
Straight Flush: 40 to 1
3 of a kind: 30 to 1
Straight: 6 to 1
Flush: 4 to 1
Pair: 1 to 1
(Straights are A-2-3 to Q-K-A)

All games are for 0.10 btc, and an amount greater than that will result in multiple games. Winnings are not gambled. Amount less than 0.10 will be wagered in entirety.

Play anytime you feel lucky. 3 Card Poker address: 1CracksLRtQMcTF4HXNrvPzRgvz7Qr6wNd

The shuffling algorithm explained:
The unshuffled deck begins with 52 cards in sequence. The sequence is Ace,2,3,4,5,6,7,8,9,10,J,Q,K for each suit, Hearts, Spades, Diamonds and Clubs.
When the hash seed is determined, the two leftmost hex character are taken from the hash. For the resulting hex byte to qualify it needs to be less than the quotient of (value / cards remaining) * cards remaining. This is to ensure an equal chance for every card to be selected. If the hex byte does not qualify, the next pair of characters from the hash is used.
Once a qualifying byte is found, card MOD( value / cards remaining) is moved to the end of the deck. This is done 52 times. When necessary, the process SHA256(Hash) is performed to keep the process going. Note that the first 3 cards moved would be cards selected for play.

We introduced a service called (wait for it) "the crack pipe", because you can pipe wagers through to a fixed address that you own.The announcement is here: https://bitcointalk.org/index.php?topic=121920.0.

We create a custom 1Pipe address for you that makes a wager according to your terms, and forwards those winnings to an address of your choosing. With it, you post your personal 1Pipe address for tips, raise donations or sell products. All wagers will show up on DoC.

Its in beta right now. Please post or PM me for a custom 1Pipe address. Include what wager you would like to use.

Thanks, and good luck!

Great concept, you guys really do great work.

Global win-cap has been increased to 25.000 btc max. This may still change based on hot-wallet balance at the time.

Great concept, you guys really do great work.

Thank you!

It seems the bitcoin client used for processing payments is refusing to sign the payout transaction, which is quite awkward as it should only happen if the transaction or the block was rolled back, which isn't the case.

I'll keep trying to fix this, but in the mean time I'll send you a manual payment. If I do fix this there's a good chance you'll get a double payment, which I'm sure will greatly upset you

A major milestone with DiceOnCrack, and bitcoin in general - we were able to verify our first DoC Pipe winner! It was sold by Bitcoiner2012 who received 4.494 coins on a 0.40 wager by an anonymous forum member. The anonymous person signed a message with the sending address that contained his shipping information.

With interest, we want to make the process more streamlined.

Congrats go to Bitcoiner2012 and to anonymous, as DiceOnCrack took the loss but facilitated a transaction that otherwise wouldn't have existed.

If you would like a Pipe address, please PM me! If you decide to play a Pipe, please note DiceOnCrack only hosts the lottery/wager, and does not hold the goods.

UPDATE: Our promotion with 0.10% fees will end within the next 24 hours. This will only apply to the [EXIT] Strategy, which has been bet heavily the last few days. We have been losing money due to fees. For those who have been playing, we enjoy the bets, but the fees per payout is unsustainable. The other martingales will continue to enjoy the 0.10% fee for wagers between 0.1 and up to 2.0000 btc.

1.5+ Million iterations so far since launch!

Good Luck

[TTBit]

Update: DiceOnCrack.com server was updated, and should be a bit quicker to load. We still offer 99.90% per iteration promotion on many wagers.

Each transaction is mingled with the secret of the day

I see the secret is published the next day, but how do I know a secret wasn't changed depending on the results of the first bet of the day?    Is there a hash of the secret published in advanced so that later when the secret is published it can be verified to be unchanged from before the wager was placed?

Today's secret is sha(tomorrow's secret).

From how to play:
The secrets used in the HMAC_SHA512 portion of the seed are disclosed after 2 days, and they can be verified as each day SHA256 hash will be the previous day secret
This means that we have pre-calculated all the keys, as we can only know today's key if we already know tomorrow's, and the next day, and so on, since SHA256(today's secret) which is yesterday's secret had to be calculated ahead of time.

Ah, clever.

Just to clarify, does date that the secret is used correspond with UTC? (versus some other timezone?)

Yes, all times for DiceOnCrack, TAABL and LBAAT are UTC, including the secrets. The secret used is the one from when the bet is processed, not from when it is parsed, and there is a chance that a bet processed at 00:00 UTC will still use the previous day's secret.

The address in the "adress" section of the table has seemed to change, I'm not sure if that is intentional or not.

Nice catch! I can confirm we own the private keys to those addresses. I believe they were our testing address when setting it up. Might not have transferred to the new server correctly.

Indeed that's just a side effect of the strategy having had an address change in the past. The old address is still valid and that's what you were seeing, I've fixed it now.

It will still show the same behaviour is you search for the old address: http://diceoncrack.com/address?_=1LQXotaEjfmerkwrGB3dHnheujo7sng6vA only  the other way around. Good eye.

The hot wallet on TAABL / DoC / is in need of a kick. This being a holiday, it probably won't be fixed for the next 8-12 hours. Bets can still be placed in queue. We are looking into redundancy. Thanks for your patience and happiest of holidays!
