Mines is dice wearing a grid: 25 tiles, you choose how many mines hide among them, and every safe pick multiplies your cashout by slightly less than the true odds of surviving it. The gap is the published edge; the rising ladder is the game.
The survival math
With m mines in 25 tiles, your first pick survives with probability (25−m)/25; each subsequent safe pick recalculates over the remaining tiles. Fair multiplier after k safe picks = 1 ÷ P(surviving k picks); the game pays that times (1 − edge).
Three mines, the common default:
| Safe picks | Survival probability | Fair multiplier | Paid at 1% edge |
|---|---|---|---|
| 1 | 88.0% | 1.14x | 1.13x |
| 3 | 67.1% | 1.49x | 1.48x |
| 5 | 49.4% | 2.02x | 2.00x |
| 10 | 16.5% | 6.07x | 6.01x |
| 15 | 2.6% | 39.0x | 38.6x |
If you want the math: P(k safe picks) = C(25−m, k) ÷ C(25, k). With 3 mines, 5 picks: C(22,5)/C(25,5) = 26,334/53,130 = 49.6% — the two-times-your-money point sits almost exactly at the coin-flip, as the formula guarantees it must.
What mine count changes
Mine count is the variance dial. One mine plays like a high-win-chance dice setting — long grinds, tiny multipliers. Twenty-four mines is a single-pick lottery ticket (4% survival, ~24x at fair odds). The edge stays constant across the dial at any given implementation; the published number on the info page is the price everywhere on it.
The cashout decision
Every safe pick offers the same choice: bank the current multiplier or risk it on the next tile. Because each step is priced at (1 − edge) of fair value, no stopping point beats another by expectation — the crash-game logic exactly. The discipline that matters is deciding the target before the first pick (k picks, then cash) and automating it where the client allows. Mid-grid decisions after a streak of greens are where bankrolls go; the ladder is engineered to make the next tile feel small.
Verification works as everywhere in the family: the mine layout derives from the committed seeds, recomputable after rotation. The pillar walkthrough applies unchanged.
