Mines Game: The Hidden Grid, the Mine Count and the Cash-Out Decision

Recorded here for good, and applicable to any title in the format: how a mines game’s grid works and how the number of mines shifts your odds. You set a mine count, a hidden board fills with that many mines, and you open tiles one by one until you cash out or hit a mine. PH365’s menus give the format no tab of its own, so a title of this kind is found under the studio that supplies it. The rest of this page is arithmetic that holds for any fair board.

How the mines game grid and cash-out work

1. Pick a stake and a mine count before the round begins.
2. The board fills with hidden mines in places you cannot see.
3. Open a tile: a safe one raises your running payout, while a mine closes the round with your stake gone.
4. Once a tile has come up safe, the cash-out is open and collects that running payout.

Step 4 is the only decision that matters in the round. Every tile you open after a safe one puts the running payout at stake along with your original bet.

How the mine count changes the odds

The board below is a sample of 25 tiles, chosen for the arithmetic. A tile’s chance of being safe is the number of safe tiles left divided by the tiles left.

Each row compresses into one idea: extra mines change the tile you are about to open as well as every tile after it. A title’s payout table raises the reward to match, so a higher mine count is a different risk and never a free improvement.

Problem: after several safe tiles the next one feels safer, since so many have gone well. Fix: the opposite is true on a fixed board; safe tiles leave fewer of them remaining, so the mines make up a larger share of what is left.

What a fair payout would look like

Payout tables differ by title, so the sums below use the same sample board and only show the break-even line. A multiple that exactly offsets the risk of a run of safe tiles is one divided by the chance of that run.

A title’s real table will pay less than the break-even line, because the house keeps a margin, so compare any quoted multiple against these figures to see how much of that margin it takes on the tile you are about to open.

Mines against other cash-out formats

That is the appeal of this format: unlike crash games and their hidden stopping point, the board’s odds can be worked out before you open a tile. Plinko’s path counts share that quality, with less to decide once the ball is released. The wider shelf sits in the fishing and arcade hub, and for anyone without an account on that lobby, the register field list explains what its form asks.
