Dice
Provably fair dice roll
Paste the revealed server seed, your client seed, and the nonce from the fairness panel. The roll is a deterministic value from 00.00 to 100.00.
SHA-256(server seed)
Result digest
Algorithm: digest = SHA-256(client_seed:server_seed:nonce).
Take the first 4 bytes as an unsigned 32-bit integer, then
roll = ((uint32 * 10001) / 2^32) / 100.
This is multiply/divide, not modulo, so the 10,001 outcomes stay unbiased.
Query params: client_seed, server_seed, nonce, hash.
