about

Provably fair is a promise. Somebody should check it.

“Provably fair” is the best idea crypto casinos have had, and almost nobody uses it. The verifiers casinos ship are buried three menus deep, work only for their own games, and explain nothing. VerifyRoll is one place that recomputes a bet from any Stake-scheme operator, shows the working, and sits next to the other half of fairness that the scheme cannot prove: the odds.

What we will not do

We will not estimate. If an operator does not publish an RTP, the table says so instead of guessing. We will not editorialise about operators. The house-edge table carries published figures, the date we checked them and where they came from, nothing more. We will not hide who pays for this. VerifyRoll is sponsored by Craze; the disclosure is in the footer of every page and in full on the commercial disclosure.

What you can hold us to

Every derivation in the verifier is open to inspection, tested against the published construction, and runs entirely in your browser. When we get something wrong, the fix goes in the changelog with the date. If you find a bet that verifies on a casino's own tool and not here, tell us and we will treat it as a bug.
