Provably fair
Verify any spin
Every outcome is decided before the reel moves, by a hash we commit to in advance. Once a server seed is rotated it is revealed, and anyone can reproduce every roll it ever produced.
How it works
- 1. We publish
sha256(serverSeed)before you play. The seed itself stays encrypted. - 2. Each spin computes
HMAC_SHA256(serverSeed, clientSeed + ":" + nonce). - 3. The first 13 hex characters become a number, reduced modulo the ticket count. That ticket falls in exactly one prize range.
- 4. On rotation we reveal the seed. Its hash must match what we published — check it below.
If the first 13 characters land in the small non-uniform tail of the range, we advance to the next 13 characters of the same digest instead. This removes modulo bias without changing the message you verify.
