Roobet Wheel verifier
Independently check any Roobet Wheel bet. Wheel spins to one of N equal segments. Faircheck maps your float onto the wheel you actually played — set the segment count and the winning index is reproducible.
Popular crypto casino whose original games expose a rotatable server seed and incrementing nonce.

How to verify Roobet Wheel
- Reveal the seed. Open Roobet’s provably-fair panel and rotate your seed pair — this reveals the previous server seed and shows the SHA-256 hash it was committed to before you bet.
- Find the nonce. Each bet on a seed pair has an incrementing nonce. Use the nonce of the exact Wheel round you want to check.
- Paste & verify. Drop the server seed, client seed and nonce into the form above. Faircheck recomputes the segment and confirms the seed hash matches.
The Wheel formula
Bytes from HMAC-SHA256(serverSeed, `clientSeed:nonce:round`), converted to floats and mapped per game. The server seed is committed as a SHA-256 hash before the bet and revealed when you rotate seeds.
A single float in [0, 1) is generated.
It is multiplied by the number of segments and floored to pick the winning index.
Risk levels change how many segments and which multipliers sit on the wheel, so the segment count must match your bet.
Wheel verification FAQ
Why set segment count?
Different risk levels use different numbers of segments. The float is the same; only the mapping changes.
