Provably fair
You can check that every round on Kingz Originals was random and that nobody, including us, could have changed the outcome after you placed your bet.
1
Before you play
We generate a random server seed and show you its SHA-256 hash. You bring a client seed (edit it whenever you like). A nonce counts the rounds played with that pair.
2
Every round
The mine positions come from HMAC-SHA256(server seed, clientSeed:nonce:cursor), read as 32-bit numbers with rejection sampling, driving a Fisher-Yates shuffle of the 25 tiles. No other input exists.
3
After you rotate
Rotating your seed retires the pair and reveals the server seed. Hash it yourself, recompute the positions with the code below, and compare with what you saw. It matches, every time.
