Mines: how many mines to pick

What the number of mines decides

Every tile you open is safe or a mine. With 3 mines the first pick is safe 88% of the time. With 10 mines it is safe 60% of the time. Each further pick is a little riskier than the one before, because fewer safe tiles are left.

The same five picks at two settings

Open five tiles in a row with 3 mines and you clear all five in 49.6% of rounds, for a multiplier of 2x. With 10 mines the same five picks succeed in 5.7% of rounds and pay 17.52x.

The multiplier is the fair price of that chance with the house edge taken off. A setting that pays more does so exactly because it succeeds less often.

What the choice does not change

The house edge is the same at every mine count and every number of picks. With an edge of 1%, each unit you stake costs the same on average whether you play 3 mines or 10. What RTP means in crash games explains that figure, and the expected loss calculator turns it into money.

So there is no mine count that wins more. The choice is about the shape of the session: frequent small results, or rare large ones.

How to choose a setting that suits you

• Decide how many picks you plan before the round, then read the chance to clear them in the Mines calculator.
• If a long run of lost rounds would end your session, pick fewer mines or fewer picks.
• If you want a rare large multiplier, raise the mines and accept that most rounds end early.
• Keep the stake fixed. Doubling after a loss does not help here either: does Martingale work on crash games?

Risk settings in other games

Mines is not the only game where you set the risk yourself. Plinko risk levels change the pay table in the same spirit: the average stays, the spread changes.
