Provably fair

Trust the math, not the house.

1 · Commit

Before you bet, the house publishes a SHA-256 hash of a secret server seed. It can never change it afterwards.

2 · Bet

Your client seed + an incrementing nonce feed an HMAC-SHA256 stream that deterministically produces the roll.

3 · Reveal & verify

Rotate your seed to unveil the server seed, then recompute every roll yourself. The math can't lie.
