How it works
Commit, reveal, recompute
A provably fair game commits to its randomness before you bet. The operator hashes a secret server seed and shows you the hash; your browser contributes a client seed; each round’s outcome is computed from both plus a counting nonce. Because the hash was published first, the operator cannot change the server seed after seeing your bets — any tampering would break the hash.
When you rotate seeds, the old server seed is revealed. Feed it into our verifier along with your client seed and nonce and you can recompute every result you were dealt. The proof covers in-house originals only — and it proves fairness of outcomes, not that withdrawals get paid, which is why trust is scored separately.

Questions
About provable fairness
What does provably fair actually mean?
Before a round, the operator commits to a hashed server seed; you contribute a client seed; the result is derived from both. After the round, the server seed is revealed, and because its hash was published in advance the operator cannot have swapped it. Recompute the result yourself and it must match what you were shown — that recomputation is the proof.
Does provably fair mean the casino is trustworthy?
No. It proves one narrow thing: that the outcome of a provably fair game was not rigged after your bet. It says nothing about whether withdrawals get paid, how bonus terms are enforced, or what happens to your funds — which is why trust is scored separately and carries the largest weight in our methodology.
Which games are covered?
Only the operator's own in-house games — Mines, Limbo, Dice, Crash, Plinko and similar originals. Third-party slots and live-dealer tables are not provably fair anywhere: their outcomes come from the provider's certified RNG, which is audited rather than player-verifiable.
How do I verify a result myself?
Take the revealed server seed, your client seed, and the nonce from the game's fairness panel, and run them through the published algorithm. Our free verifier does the HMAC SHA-256 arithmetic in your browser — nothing is sent to any server — and tells you whether the revealed seed matches its pre-committed hash.
