How to verify a Stake round

  1. Rotate or end the seed pair in your account so the casino reveals the server seed it committed to. Until that happens the hash is a promise, not a proof.
  2. Copy the revealed server seed, your client seed and the nonce of the round you want to check — the nonce is the round counter, not a timestamp.
  3. Paste all three into the verifier above and pick the game. It recomputes the Stake construction locally and derives the outcome the same way the operator's server did.
  4. Compare the result with what your bet history shows. A mismatch on any single round is the only evidence of tampering that actually means something.
  5. Check the committed hash too: hash the revealed server seed and confirm it equals the hash the casino published before you played.

Verification proves the result was not changed after you bet. It does not make any game profitable — the house edge is applied openly, in the payout table, and it is unaffected by any of this.
