Winner Selection
Once both payments confirm, we use the Bitcoin blockchain to pick the winner fairly.
We take the last hex character of the block hash that confirms your bet:
- 0-7 = Creator wins
- 8-F = Matcher wins
This gives true 50/50 odds using Bitcoin's random block hashes.
Rake
- 5% on pots up to 100k sats
- 1% flat on pots over 100k
Min Bet
Withdrawals
Unmatched bets can be withdrawn after 7 days (0.5% fee).
Provably Fair: The result is determined by Bitcoin's blockchain, making it impossible for anyone to manipulate.
- Payment Confirmation: Once your payment is confirmed on the Bitcoin network, we record the block height.
- Wait for Future Block: The result is determined by the block that is mined 2 blocks after your payment confirmation. This ensures nobody can know the outcome in advance.
- Hash Calculation: We take the last 8 characters of the block hash and convert them from hexadecimal to a number.
- Result: The number is divided by 38 (for American roulette) and the remainder (0-37) is your result. Result 37 = 00.
Result = parseInt(blockHash.slice(-8), 16) % 38
You can verify any result by looking up the block hash on mempool.space and running this calculation yourself.
