Snake

Snake generates five rounds with either two or four dice per round. Every die uses its own four-byte window, and all windows advance through one deterministic random stream.

What the verification proves​

  • Every die is deterministic. The same server seed, client seed, nonce, and dice selection always reproduce the same five rounds.
  • The byte cursor advances correctly. Each die begins four bytes after the previous one, including when the stream crosses into a new HMAC block.
  • The dice selection is part of the result. Two dice produce 10 draws; four dice produce 20 draws.
  • The complete calculation is visible. Floats, byte windows, die values, functions, parameters, and final rounds are shown in the wizard.

The server seed must have been committed before the bet and revealed afterward. The seeds determine the dice; payout coefficients do not take part in generating them.
