Fairness tool

Provably Fair Seed Hash Verifier

Paste the server seed revealed after a round and the SHA-256 hash committed before play. The check runs locally in your browser.

How to verify a round

1. Record the server-seed hash before play.
2. Record the client seed and nonce shown on the receipt.
3. After reveal, confirm the seed hashes to the original commitment.
4. Use the game-specific receipt to reproduce the outcome inputs.

What this proves

A match shows that the revealed server seed corresponds to the hash committed before play, so the operator did not substitute another seed afterward. This hash-only tool does not by itself prove the payout table, RNG mapping or implementation is correct; those require the game-specific algorithm and independent review.
