Fairness

Every result is decided before you bet and locked — the casino can't change it, and you can check it yourself. Here's the whole idea:

🔒 We seal a secret numberBefore your bet, the game picks a secret and shows you only its fingerprint. It's locked in — it can't be swapped afterwards.

🍀 You add your own luckYour "lucky number" is mixed in, so you influence every result. You can change it anytime.

✅ Anyone can checkAfterwards the secret is revealed. Re-doing the math gives the exact same result — proof it was never rigged.

For the technically curious

Each result is HMAC-SHA256(server_seed, "client_seed:nonce:cursor") read as big-endian integers. We publish the server seed's SHA-256 hash before you play (the commitment); reveal the seed itself via Seeds → Change to verify any past bet under the Verify tab.

Rotate seed pair

Rotating reveals your current server seed (so you can verify past bets) and commits a new one.

New client seed

Paste a revealed server seed (or open History → View to prefill) and re-compute the outcome.
