Provably Fair — Verify Every Result
How our server seed, client seed and nonce system works, and how to verify any round yourself with HMAC-SHA256. 18+ only. Play responsibly.
Every round of Palm Tuta is generated from a secret server seed, a client seed you can change and a nonce, combined with HMAC-SHA256. The hash of the server seed is shown before you play. When you start a new seed the old one is revealed, so you can recalculate and verify each result yourself.
Frequently asked questions
What does provably fair mean?
Before you play, we show you a SHA-256 hash of a secret server seed. Each result is generated with HMAC-SHA256 from that server seed, your own client seed and a nonce that counts your rounds. When you rotate your seed, the original server seed is revealed, so you can recompute any past result and confirm it was fixed before you placed your bet.
