Check a saved receipt.

Four steps to check an account round

1. Sign in, select your mode and open Receipts. Copy the next commitment before placing a round.
2. Choose your client seed in Profile. A seed generated on the standalone verifier page does not update your account; paste it into Profile first.
3. After settlement, copy that round’s proof JSON.
4. Open the fairness verifier, paste the JSON and compare its commitment with the one you saved before play.

What the verifier reproduces

The browser verifier recomputes the disclosed seed hash, outcome and gross return using the receipt’s rules version. Historical receipts keep their original mathematics.

A matching result shows consistency with the disclosed inputs. An independently saved pre-play commitment helps establish continuity. A receipt alone does not prove when its commitment was published.

Know the limits

Verification does not predict the next result, remove a house edge, authenticate a receipt’s origin or certify the running server. Published source hashes and a browser check are not an outside certification.
