Provably Fair
Every box opening is cryptographically verifiable. You can confirm we didn't manipulate any result.
How it works
- Server seed — we generate a secret random seed and show you its SHA-256 hash before you play. We can't change it after committing the hash.
- Client seed — you control this value. Change it anytime.
- Nonce — a counter that increases by 1 with every box you open.
- The roll —
roll = HMAC_SHA256(server_seed, client_seed:nonce), with the first 8 hex characters mapped to a number in [0, 1). That number selects the prize from the box's weighted loot table. - Reveal — when you rotate your seed, we reveal the old server seed so you can re-compute every past roll and confirm its hash matches.
