SPIN THE WHEEL
TRY YOUR LUCK
Place your chip on a number, then spin the wheel. Each spin uses a hidden
server seed, a client seed, and a
round number to generate a verifiable random result between 1 and 30.

Formula
combined = serverSeed + ":" + clientSeed + ":" + round
hash = SHA256(combined)
value = first 8 hex chars of hash, as integer
result = (value mod 30) + 1
hash = SHA256(combined)
value = first 8 hex chars of hash, as integer
result = (value mod 30) + 1
Last spin – combined string

You can recompute any spin in an external SHA-256 tool using the values above.
Applying
(value mod 30) + 1 to the integer from the first 8 hex chars
should give the same Winning Number shown above.
