How to play

How Mines works

Pick mine count (1–24). Place a bet. Click tiles one by one. Each safe tile bumps the running multiplier — the more mines, the bigger the jump per pick. Hit cash-out at any point to bank current multiplier × stake. Hit a mine and the round ends with a loss. Keep going for bigger multiplier; cash out for guaranteed return.

Strategy

Picks per round and EV math

EV per round is the same regardless of how many tiles you uncover — long-run return is fixed at 99%. What changes is variance: 3 mines + cash out at 1 tile is near-flat; 24 mines + 4 picks is a coin-flip parlay paying 100×+. Pick a target multiplier in advance (3×, 5×, 10×) and stick to it — the bias to chase 'one more tile' is the only real way to lose money on Mines.

Provably fair

How to verify a Mines round

At round-start, the mine positions are derived from HMAC-SHA-256 of the seed pair + nonce, mapped through a public shuffle to the 25 grid positions. Verify by recomputing the digest and confirming the same 25-position permutation the casino used.

FAQ

Mines FAQ

Is there a 'safe' first tile?

No. Every position on the grid has identical mine probability at the start of the round. The corner is no safer than the centre.

Does picking pattern (corners, diagonals) matter?

No. Mine positions are randomised for the round; pick order does not change EV. Pattern picking is psychological, not mathematical.

Can I auto-bet Mines?

Yes. Auto mode lets you set the number of picks per round, mine count, stop-on-loss, stop-on-profit. Useful for the volume needed to converge on 99% RTP.

What is the maximum win on Mines?

Up to 1,000,000× on the 24-mine, 1-pick edge case (probability ~1 in 25). Capped at the standard $250,000 daily payout cap.
