Provably Fair System
The winning number is a single integer 0–36, derived from HMAC-SHA256(server_seed, client_seed:nonce). The first 4 bytes are converted to uint32, then modulo 37 gives the result. Uniform distribution across all 37 pockets is verified mathematically.
Visit the Fairness Verification page to verify any past round with your seeds.
