Recompute any Diamonds round from the revealed server seed, your client seed and the nonce. House edge: ~1.7%.
Seven gem colors are shuffled with seven floats and five are drawn. Payouts depend on the combination (pairs, three-of-a-kind, full house of colors, five of a kind).
The complete draw order is committed up front — the verifier shows all five gems.
Odds and payouts
Combination probabilities follow simple urn math; five-of-a-kind is the jackpot tier.
How to verify a diamonds round yourself
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.
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.
Paste all three into the verifier above. It recomputes the HMAC chain and derives the diamonds outcome the same way the operator's server did.
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.
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 diamonds profitable — the ~1.7% house edge is applied openly, in the payout table, and it is unaffected by any of this.
