BitPlay Club adds European Roulette based on Bitcoin Blockchain

BitPlay Club, a popular and provably fair Bitcoin lottery based on the Bitcoin blockchain recently expanded their product offering with a new and innovating game of roulette. Just like the lottery games offered by BitPlay Club their roulette game, which is a European version of roulette, is played with Bitcoin and is provably fair thanks to their use of the Bitcoin blockchain.

Playing this game of roulette is a bit different than what most gamblers are used to with online casinos. Fortunately it’s actually quite simple if you follow these steps:

  1. Choose your bet.
  2. Send Bitcoin to the address associated with that bet. Your bet (transaction) will play in the same block that has been included into.
  3. Wait for the result. Bets play approximately every 10 minutes. Exact time depends on the time of block generation on the Bitcoin blockhain. The result is calculated via the formula below.
  4. Collect your winnings! If your bet won, your bet and prize would be sent to the same Bitcoin address you made a bet with.

Provably fair Roulette

Over the years the BitPlay Club management noticed a huge increase in online gambling and also noticed roulette being one of the most popular online casino games. However, they also noticed quite a bit of distrust in online casino sites. According to BitPlay Club they want you to be absolutely sure that the games you play are safe, secure and most of all fair. By offering a provably fair version of roulette the player can verify if the game he or she played was fair by following a few simple steps based on information from blockchain.com. That information can be entered at the BitPlay Club fairness calculator or your own calculator or Excel sheet if you don’t want to use a tool from BitPlay Club.

How does this calculation work? It’s actually quite simple:

  1. First take the hash of the block with your transaction, height of this block, its time of generation and the hash of the previous block.
  2. Stick all this data together and encode it to the MD5 hash algorithm. Received hash value is being encoded into Crc32 hash algorithm.
  3. Calculate the remainder in division by 37.
  4. The number received after step 3 is the winning number.

Example

First we have to find some data of our transaction:

Block hash of our transaction: 00000000000000000cbb49e808da731aeb1246035e26881a734fc1307a9a9577

Height of this block: 376594

Time of generation: 2015-09-29 00:22:51

Hash of the previous block: 0000000000000000069d9bef981a97a9066a5574e9d5148b533b4e0719838443

Once we have all that information we can enter it into the formula:

(

crc32(

md5(

               md5(0000000000000000069d9bef981a97a9066a5574e9d5148b533b4e0719838443) +

               md5(376594) + md5(2015-09-29 00:22:51 UTC) +

               md5(00000000000000000cbb49e808da731aeb1246035e26881a734fc1307a9a9577)

)

) MOD 37

) = 6

As shown in the calculation above the remainder equals 6, making 6 the winning number!
