How a round works
Mines is played on a 5-by-5 grid with 25 hidden tiles. Before a round starts, you choose your stake and the number of bombs, from 1 to 24. The other tiles contain gems. The bomb positions are hidden, and each round relies on a random number generator.
After every safe tile, you face the game’s main decision: cash out the amount shown or reveal another tile. Each gem you uncover increases the round’s multiplier. If you reveal a bomb, the round ends and you lose your stake. Cashing out before hitting a bomb ends the round with the amount displayed at that point.
How to calculate the odds
The chance that your next pick is safe depends on how many safe tiles and how many unrevealed tiles remain. Divide the number of safe tiles remaining by the number of unrevealed tiles. After each gem, both counts decrease by one, so the probability changes as the round progresses. The initial bomb count sets the starting risk: more bombs mean fewer safe tiles to choose from.
For example, with 3 bombs, 22 of the 25 tiles are safe. Your first pick has a 22/25, or 88%, chance of being safe. If it reveals a gem, 21 safe tiles remain among 24 unrevealed tiles, so the next pick has a 21/24, or 87.5%, chance of being safe. The chance of getting through both picks safely is 22/25 × 21/24, or about 77%. This does not show where the bombs are; it describes the probability of safe picks, assuming a random distribution.
What changing the bomb count does
Choosing more bombs makes each pick less likely to be safe and generally makes the multiplier rise faster. With one bomb, the first tile has a 24/25, or 96%, chance of being safe; with 24 bombs, that chance is 1/25, or 4%. A larger multiplier does not make a risky pick more likely to succeed: these are separate features of the round.
There is no sequence of clicks that can predict a bomb or guarantee a profit. Probability describes risk; it does not reveal tile locations. Before playing, set a spending limit and treat the stake as money you could lose in full. If you choose to continue after finding a gem, weigh the risk of another pick against the amount you can already cash out. Stopping does not change future outcomes, but it ends your exposure for that round.
