Provably Fair

Don't trust — verify. Recompute any spin outcome right here in your browser.

1. Commit. Before your spin, the wheel page shows the SHA-256 hash of the server seed that will decide your next outcome. At this point the seed — and therefore the result — can no longer be changed without breaking the hash you already saw.

2. Your input. You control the client seed (editable in the Provably Fair panel) and can see the nonce. The house cannot predict your seed; you cannot predict the server seed. Neither side controls the outcome alone.

3. Reveal & verify. After the spin, the server seed is revealed. Verify below.

The verifier runs entirely in your browser (WebCrypto) — seeds are never sent anywhere.
