Provably Fair

At RoLuck, we believe in radical transparency. Every game you play can be mathematically verified for fairness.

Unbiased RNG

Our system uses cryptographically secure random number generation to ensure every flip of the coin is independent and 100% fair.

Server Seeds

Every match is anchored by a server seed that is hashed and revealed only after the outcome is finalized, preventing any manipulation.

Verifiable Proof

You can verify every single game using our open-source verification scripts. Transparency is our core value.

Technical Overview

Our provably fair system utilizes the standard HMAC_SHA256 algorithm. When a match is created, a Server Seed is generated and its hash is shown to all players. After the match, the raw seed is revealed, allowing you to re-compute the hash and the result.

result = hmac_sha256(server_seed + client_seed + nonce) % 100
