Provably Fair
Every opening uses a commit-reveal scheme. The server commits to a secret seed before you open, your browser adds its own seed, and the server seed is disclosed after the reveal. You can then recompute the result yourself and confirm it was not changed after the fact.
How it works
1. Commit
Before you open, the server generates a random serverSeed and publishes SHA-256(serverSeed) as a commitment.
2. Reveal
Your browser sends a clientSeed. The result is computed as HMAC-SHA256(serverSeed, clientSeed) and mapped to a tier and prize.
3. Verify
After the reveal, the serverSeed is disclosed. You can check SHA-256(serverSeed) matches the original hash, then re-derive the result yourself.
