Betting in three easy steps
All you need to play is some Bitcoins, a new virtual currency!
STEP 1: Open a Bitcoin Wallet
Open a Bitcoin Wallet at Blockchain.info: for newcomers to Bitcoin, opening a wallet is similar to opening a bank account online. Once your Wallet is open, you will receive a long string of numbers and letters referred to as the Bitcoin Address, which is similar to your account number. From now on, you can send or receive money using your address.
If you want to open a wallet in a flash, use Instawallet. Bear in mind that this will not be password-protected so it should not be used for betting purposes. While there are other sites where you can create a Bitcoin Wallet or even download software to your computer, we always recommend Blockchain.info for convenience and security.
Additionally, you can take a look at the list of available wallets.
STEP 2: Buy Bitcoins
You wallet is open but sadly empty! Fortunately, you can easily buy bitcoins and send them to your address. We recommend buying bitcoins at Bitstamp or MtGox. You should register at one of those websites and add funds via bank transfer. Once your money is received, buy some bitcoins and send them to the address you noted earlier. Need a reminder? Your wallet address!
Alternatively, you can purchase bitcoins with a cash deposit at BitInstant.
You might want to look for other Bitcoins Markets at the Bitcoin Wiki.
OK, now your wallet is awash with bitcoins. Let's play.
STEP 3: Place your bets!
You can hit the jackpot by playing two game types: Multiply your money or Lottery Pot.
Click on the desired bet to open a popup window with a brief explanation on the betting procedure and an address, which is the bitcoin address we have created for this particular type of bet. Copy this address, login to your wallet at Blockchain.info, and click on Send Money. Paste the address you just copied and enter the bitcoin amount you would like to bet.
Excellent! That's all it takes to play.
Post-betting procedure
Please note the Recent Bets section at the bottom of the page. You can identify your bet via the player address column, which indicates the payment origin address, and review the same as required. If you win, the payout will be sent within 60 seconds to the same address from which you paid. Conversely, if you lose, 0.00000001BTC will be credited.
Please contact us should you have any betting questions or concerns.
Good Luck!
Results are provably trustworthy.
In order to ensure that there is no way for the system to change the outcome of a bet, secret keys are used to decide the outcome of all bets ahead of time. They are not released right away, since they could be used to submit selective transactions and win bets unfairly. After the secrets keys are released, users can verify that preceeding bets were provably fair.
The lucky number is generated in such a way that there is only one possible outcome for any given transaction, output (Or lottery ticket) and picked bet. To do so, the secret key, the bitcoin transaction and the transaction output are computed to generate an unique seed hash, from which the first 6 bytes are isolated to obtain the seed number and a lucky number. If the remainder -plus one- of the seed number divided by the bet range the player chose (modulus) is 1, the player wins and gets paid accordingly. If not, the player loses.
Generating the Lucky Number
Given a Transaction Hash(TX), a Secrey Key(SECRET), a Transaction Output -or a lottery ticket- (O) and a Bet Range(BR), the following steps are taken to find out the outcome.
TX:O + Secret -> Seed Hash -> Seed Number -> Lucky
First, the Seed Hash(SH) is generated from the SECRET and transaction hash.
SH = hash_hmac("sha256", SECRET, TX:O);
Right after, the first 6 bytes are isolated from the SH and cast to a 24Bit integer value between 0 and 2^24, creating the Seed Number(SN).
64fa1c1c457089527491a914c4163de -> 64fa1c -> 6617628
And finally, the Lucky Number(LN) is calculated from the SN and the BR, which changes according to the chosen bet by the player.
LN = (SN mod BR) + 1
Therefore, any given Bitcoin Transaction and output will generate one unique seed number, and the outcome of the bet is decided by the multiples of that number. Some examples can be found below:
X2 -> (6617628 % 2)+1 = 1 [WIN] X3 -> (6617628 % 3)+1 = 2 [LOSS] X4 -> (6617628 % 4)+1 = 1 [WIN] X5 -> (6617628 % 5)+1 = 4 [LOSS] X10 -> (6617628 % 10)+1 = 9 [LOSS] X50 -> (6617628 % 50)+1 = 29 [LOSS]
Hence, it is possible to make several bets in one single transaction and each bet will have a different verifiable outcome. For further information about any given bet, please review the transaction details page.

Multiply your money

Lottery Pot
This game consists of a pot of money that replenishes constantly as people play. Every player can buy a ballot or lottery ticket and have a chance to win the jackpot.

Additionally, the house allocates 40% as reserve for the next Lottery Pot.
Min / Max Bets
Because there is only a limited pool of funds to back bets, there is a max bet for each bet option which changes periodically according to the available funds. If your sent amount exceeds the maximum bet, it will be returned before evaluating the result. However, if your sent amount is below the minimum bet, the transaction will be ignored and not returned.
