Mines

A Mines board starts with two seeds, the bet nonce, and the chosen number of mines. The verifier below generates the raw floats first and then shows exactly how they become unique positions on the 5 × 5 board.

What the verification proves​

  • The board is deterministic. The same server seed, client seed, nonce, and mine count always produce the same mine positions.
  • Mine positions cannot repeat. After a position is selected, it is removed from the available tiles before the next float is converted.
  • The nonce makes each board unique. It advances once per new bet.
  • The complete calculation is visible. The wizard exposes every float, integer position, function, parameter, and generated board.

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