How to Play Mines: Rules, Strategy, and Cashout Math
Mines is the most mathematically transparent game in the casino. Pick tiles, dodge mines, cash out before you click one. Beginner's guide to rules, optimal cashout points, and verifying the mine layout was committed before you started.
How to Play Mines: Rules, Strategy, and Cashout Math
Mines is the most mathematically transparent game in the casino. A 5×5 grid (25 tiles) hides some number of mines. You pick tiles, the multiplier climbs on each safe pick, and you choose when to cash out — before you eventually click a mine and lose everything.
The strategic question — "do I click one more tile or cash out?" — has an actual mathematical answer. Once you know it, Mines becomes the cleanest expected-value game on the floor.
The rules
- You place a bet.
- You set the mine count (anywhere from 1 to 24 mines hidden in 25 tiles).
- You click tiles one at a time. Each safe pick climbs the multiplier.
- You can cash out at any time after at least one safe pick — your win is
bet × current multiplier. - If you click a mine, you lose your bet.
The multiplier at each step depends on the probability of having survived to that point. More mines = higher multiplier per pick, but lower probability of getting there.
The math
With M mines hidden among 25 tiles, the probability that your next pick is safe (given N safe picks already made) is (25 - M - N) / (25 - N).
The multiplier after N safe picks is approximately:
multiplier(N, M) = product over k=0..N-1 of (25 - k) / (25 - M - k)
For the most common setting (3 mines):
| Safe picks | Multiplier | Survival probability |
|---|---|---|
| 1 | 1.13× | 88% |
| 3 | 1.48× | 67% |
| 5 | 1.98× | 50% |
| 8 | 3.46× | 32% |
| 10 | 5.65× | 22% |
| 15 | 28.7× | 8% |
| 22 | 1898× | 0.4% |
The multiplier climbs slowly, then explodes near the end. That's by design — it tracks the rare survival rate.
Optimal cashout points
The optimal stopping rule is: cash out when the expected value of continuing is no longer greater than the certain value of stopping.
For different mine counts, the optimal cashout point is mathematically fixed. Full table here.
Key takeaways:
- 3 mines (most common): optimal cashout = 6 picks at ~2.4×
- 5 mines: optimal cashout = 4 picks at ~2.5×
- 8 mines: optimal cashout = 3 picks at ~3×
- 24 mines (forced extreme): single pick, ~24.75× — pure coin flip
Notice: across all "normal" mine counts, optimal cashout is 2.5× to 3× — not the 5× or 10× most players hold out for. Holding past the optimal point reduces expected value because the probability of busting climbs faster than the multiplier.
Common beginner mistakes
Cashing out too early. Banking 1.1× or 1.2× wins gives up almost all the expected value. The marginal pick is profitable far longer than instinct suggests.
Cashing out too late. Holding for 5×+ on 3 mines means you're betting 32%+ probability of busting against a marginal EV gain. Most rounds end at zero.
Switching mine counts mid-session. Each mine count has different optimal stopping. Bouncing between them resets your intuition for the curve.
"Pattern reading" tile positions. On a provably fair mines, the layout is committed before your first click. There is no pattern to read. Click any tile — they're statistically equivalent.
The 24-mine special case
If you play 24 mines (one safe tile among 25), you make a single pick. Survive: win 24.75×. Bust: lose. EV is identical to a 50/50 coin flip with 50% payout. This is a pure entertainment variant — fun for one round at a time, not a sustainable strategy.
Provably fair mines — verify the layout was committed
This is where Mines specifically benefits from cryptographic fairness:
A non-provably-fair Mines could, in theory, place the mine where you click next — adjust the layout dynamically based on player picks. You'd never detect this without thousands of rounds of statistical analysis.
Provably fair Mines prevents this:
- Before your first pick, the mine layout is committed via SHA-256 hash
- The hash is published before you click anything
- When the round ends (cashout or bust), the seed is revealed
- You hash the revealed seed and recompute the full layout
- Confirm: the mines never moved
This is the strongest fairness guarantee in any casino game, because the layout is locked at round start and proven afterward. 6proclub does this on every Mines round.
Bankroll guidance
Mines has lower variance than Crash or Plinko at low mine counts and high variance at high mine counts. For a small-deposit session:
- 1-2 mines, $1/round, 3-4 picks: very stable, ~80% hit rate
- 3 mines, $1/round, 6 picks: optimal EV, ~50% hit rate
- 5-8 mines, $0.50/round, 3 picks: higher variance, ~50-67% hit rate
- 10+ mines: lottery-style, expect to lose 7+ rounds for every win
Pick one configuration for a session. Bet the same amount on each round (Kelly criterion if you want to optimize, but flat-betting is fine).
Common strategy variations
Auto-pick patterns: Some Mines implementations support clicking a fixed pattern (e.g., always the four corners). On a provably fair Mines this is statistically identical to picking randomly — every tile has the same probability of being a mine.
Hot/cold streaks: Not a thing. Each round is independent. A round that just produced 10 safe picks doesn't make the next round more or less likely to bust at pick 3.

In one paragraph
Mines is the most mathematically transparent game in the casino: layout is fixed at round start, expected value of each marginal pick is computable, and the optimal cashout point is known. For 3 mines (the popular preset), cash out at 6 picks. Provably fair commitment cryptographically guarantees the mines never moved. The discipline is sticking to the optimal cashout instead of chasing bigger multipliers — most "I almost won 50×!" stories end at zero.
