DICE PROVABLY FAIR VERIFIER

Dice is the simplest provably-fair game: each roll produces a number from 0.00 to 100.00, and you bet whether it lands over or under a target. Because the result is a direct function of your seed pair and nonce, you can recompute every roll exactly. Paste your revealed seeds below to verify any Dice outcome.

HOW DICE RESULTS ARE CALCULATED

Dice consumes a single random float from the HMAC stream and scales it to the 0.00–100.00 range:

1. Compute HMAC-SHA256(serverSeed, "clientSeed:nonce:0") and take the first 4 bytes as a float in [0,1).
2. Apply roll = floor(float × 10001) / 100 → a value from 0.00 to 100.00.

Worked example — server seed some server seed, client seed some client seed, nonce 1 gives float 0.59192619 → roll 59.19. Paste them into the tool to confirm.

The math is validated against published reference test vectors, so the number here matches Stake and any other Stake-style casino exactly.

WHY VERIFY DICE?

Provably fair only protects you if you actually check it. Verifying a Dice round proves the result was computed from the server seed the casino committed to before your bet, combined with the client seed you chose — so the operator could not have altered the outcome after seeing your wager. Spot-checking even a handful of rounds keeps the system honest and removes any doubt during a losing streak.
