How it works
- The house commits to a secret server seed by publishing its hash.
- You choose a client seed and payout address. These, the stake and the payout are locked into the bet terms.
- You pay the stake to a fresh Ark address made just for this bet.
- The roll is HMAC-SHA256(server_seed, terms) → 0–9999. Below the target wins.
- The server seed is revealed. Verify everything yourself, right in this page.

Verification
The server seed stays secret until the bet stops accepting stakes. Then you can check every step here.

Verify any receipt
Paste a receipt JSON downloaded from a bet. This check runs locally in your browser with WebCrypto and shares no code with the server. You can also run dice-verify receipt.json.
Verifier self-test
The browser verifier checks itself against the published reference vectors (test-vectors.json), which the Rust engine also tests against.
