Twenty tiles hide gems and mines. Choose how many mines (1 to 15), place your bet, and turn tiles one at a time. Every gem raises the multiplier; a mine ends the round and the bet is lost. Cash out whenever you like to take your bet times the multiplier.

More mines means a steeper climb: with 3 mines the first gem pays 1.14×, with 10 it pays 1.94×. Every cash-out point returns the same 97% on average, however many mines you pick or wherever you stop. In Auto, pick the tiles once and they're turned for you every round, with a cash-out after the last one.

The mines are placed from your own provably fair seed pair when your bet goes in, before your first tile, and never move. After the round, or with New seeds, check the board on the Provably fair page. A round left open is cashed out after ten minutes (one tile is turned for you if you hadn't turned any).
