Twenty-five tiles, and you choose how many of them hide a mine. Open tiles one at a time: every safe tile raises your multiplier, and a mine ends the round and takes your bet.

• -Set your bet and pick a mine count from 1 to 24.
• -Press Bet, then open tiles in any order you like.
• -Cash out whenever you want to bank the current multiplier.
• -Open every safe tile and it pays out automatically.

The multiplier is the reverse of how likely you were to get this far. Open a tile and the odds of the next one being safe get worse, so the payout for surviving it gets bigger.

It depends on three things: how many mines you chose, how many tiles you have opened, and how many are left unopened. More mines means fewer safe tiles, so each one you find is worth more.

Exactly 5% is taken off every payout, which is the house edge. Your expected return is 95% of your stake whatever mine count you pick and however deep you go - no pattern of play beats that.

A few multipliers, for scale:

Clearing the whole board pays the most a mine count can give:

With one mine and one tile opened the multiplier is just under 1x, so cashing out there returns slightly less than you staked. Open a second tile and you are ahead.

Every tile is equally likely to be a mine, so where you click makes no difference at all. The only real decision is when to stop.

• -Few mines and many picks gives frequent small wins.
• -Many mines and few picks gives rare large wins.
• -Both return the same 95% on average - they only differ in how bumpy the ride is.
• -Decide your cash-out point before you start, then stick to it.
• -Nothing carries over between rounds. The mines are reshuffled every time.

Chasing a loss by raising your bet does not change the odds of the next tile. It only raises how much you can lose on it.
