How Stake Mines actually pays
The exact formula
Mines is a 5x5 grid (25 tiles). With m mines, after revealing g gems your multiplier is 0.99 x the product of (25 - i) / (25 - m - i) for i from 0 to g-1. The 0.99 is Stake’s 1% house edge; the product is simply the inverse of the probability of surviving that many safe picks.
Why multipliers accelerate
Each safe reveal removes a known-safe tile, so the next pick’s safe probability rises as the board clears. That compounding is why the multiplier curve steepens the deeper you dig, and why high mine counts pay so much on the very first tiles.
There is no “safe” tile
Every tile in a round is equally likely to hide a mine, and rounds are independent. A heatmap of past mine positions is descriptive only. It cannot predict where the next round’s mines land.
Cashout is a risk choice
Pushing one more tile has the same expected value as cashing out (minus the edge), so there is no mathematically optimal stopping tile, only your variance tolerance. Pick a target multiplier before the round and hold to it.
