How Provably Fair Works

1. Server Seed Hashing

Before you start placing bets, our game server generates a highly secure server seed and presents its SHA-256 hash. Because the hash is shown before you play, the casino cannot alter the seed after your bet.

2. Client Seed Input

You can customize your client seed. This adds randomness that the server has no control over. The combination of your client seed and the server seed determines the final output.

3. Nonce Counter

Each bet you place increases the nonce counter by 1. This generates a unique outcome for every individual roll or card flip, even if the client and server seeds remain unchanged.

Verification Steps
  1. Rotate your seed pair inside the game settings panel (this reveals the unhashed server seed of your past games).
  2. Copy the unhashed server seed, client seed, and nonce.
  3. Select the corresponding game type in the calculator and enter the values.
  4. Click verify to confirm the math match cryptographically!
