Provably Fair
Verify that every game is fair
How It Works
Server Seed Generation
Before each game, we generate a random server seed and show you its SHA-256 hash. This proves the seed existed before you played.
Client Seed
You can set your own client seed or use the random one we provide. This ensures you have input into the outcome.
Game Result
The game result is determined by combining the server seed, client seed, and nonce using cryptographic functions.
Verification
After the game, the server seed is revealed. You can verify the result yourself using our verification tool or third-party calculators.
Verify Game
Enter the server seed, client seed and nonce to verify a game result.

Technical Details
Algorithm
HMAC-SHA256 Game outcomes are determined using an industry-standard cryptographic hash function.
Formula
result = HMAC-SHA256(server_seed, client_seed:nonce) The result is calculated by combining the server seed, client seed and nonce.
