Mines Calculator: Next-Click Risk & Survival Odds

In the game of Mines, a 5×5 board hides a chosen number of mines among 25 tiles. Every safe pick raises the offered multiplier — and changes the odds of the next one, because each revealed gem removes a safe tile while every mine stays on the board.

This calculator answers one question precisely: from your current board state, what is the chance the very next click survives? It works from the numbers you can see mid-round — how many mines are set and how many gems you have already found. It does not predict tile positions, and it does not tell you whether to keep playing.

How Next-Click Odds Work

The board starts with 25 tiles. Once you have revealed g gems, 25 − g tiles remain, and all of the mines are still among them:

P(mine on next click) = Mines ÷ (25 − Gems revealed)

That single division explains the whole risk curve of a round. With 3 mines, watch how the danger climbs as the board shrinks:

The last row is the whole game in miniature: with 3 mines and only 4 tiles left, exactly one hidden tile is safe — the click that would clear the board survives just 25% of the time.

Why the Odds Shift — and Why Nothing Is Ever "Due"

Mines is a game of dependence without memory. The probabilities genuinely change from click to click — but for a structural reason, not a psychological one. Each gem you reveal removes one safe tile from the pool while the mine count stays fixed, so the mine share of the remaining board rises mechanically. That is the opposite of the gambler's fallacy: nothing is "due", no tile is "hot", and a long safe streak does not make the next click more dangerous beyond what the shrinking board already dictates. The game keeps no record of patterns; it only has fewer tiles.

Surviving More Than One Click

The chance of surviving a streak from your current state is the product of each step's survival, with the board shrinking as you go:

P(survive k clicks) = (S ÷ R) × ((S−1) ÷ (R−1)) × … — S safe tiles left, R tiles remaining

From a fresh 3-mine board, surviving the next three clicks is 22/25 × 21/24 × 20/23 = 66.96%. From mid-round — 3 mines, 10 gems found — the same three-click streak survives only 12/15 × 11/14 × 10/13 = 48.35%: identical target, worse board. The calculator above shows the 2- and 3-click streak odds for any state. To price a full run from the start of a round to a cashout target — and see the fair multiplier its probability implies — the multiplier chart on MinesCalc tabulates 1/P for every mine count and depth.

What This Page Deliberately Leaves Out

Multipliers, payouts, bet sizing, expected value and RTP comparisons live on the companion site, where each tool is built around the money side of the setup. One fact worth knowing before you go: casino multipliers sit below the fair value 1/P — that gap is the house edge, and how each platform applies it (99%, 97%, sometimes less) is exactly what Mines RTP Explained covers, including why displayed multipliers differ between casinos running the same game.

A Word on "Predictors"

No calculator — this one included — can identify which tiles are safe. In a properly random or provably fair Mines game, the layout is generated from cryptographic seeds, and previous boards, visual patterns and "AI predictor" apps provide no information about the next round. Services that claim otherwise are selling noise, sometimes with malware attached. The Predictor & Hacks page on MinesCalc demonstrates interactively why every such tool fails.
