Provably fair
Every round's outcome is determined by HMAC-SHA256(serverSeed, clientSeed:nonce). The server seed is committed (hashed and shown) before each round and revealed when you rotate.
Rotating reveals the current server seed and generates a new one. Use this to verify past rounds.

How verification works
- Before each round, the server seed is hashed (SHA-256) and shown — that's a binding commitment.
- The outcome of every round is HMAC-SHA256(serverSeed, clientSeed:nonce) interpreted per game rules.
- When you rotate, the previous server seed is revealed. Hash it yourself — it must match the prior commitment. Then replay any past nonce to verify the outcome.

How mines works
25-tile grid with N hidden mines. Each safe tile boosts your multiplier. Hit a mine and the round ends — you lose the bet.
Multiplier formula: 0.99 × C(25, picks) / C(25 - mines, picks). 1% house edge.
Mine positions are randomized at round start using crypto entropy.
