Mines 3 mines
3 mines on a 5×5 grid (25 tiles, 22 safe) is the conservative variance pick: high probability per click, low per-click multiplier. EV is identical to every other mine count thanks to the flat 1% house edge.
On Rust Snowball, the win probability on the n-th safe click given 3 mines is (22-n+1)/(25-n+1). First click 22/25 = 88%; second 21/24 = 87.5%; third 20/23 = 86.96%; and so on. The multiplier ratchets up to keep the long-run RTP at 99% regardless of stop point.
Math & key numbers
| Grid size | 5×5 (25 tiles) |
| Mines | 3 (12% of grid) |
| Safe tiles | 22 |
| 1st click safe % | 88.00% |
| 5th click safe % | 85.71% |
| 10th click safe % | 80.00% |
| Max multiplier (all 22 cleared) | ~32x (gross) |
| House edge | 1% (flat across all mine counts) |
Strategy notes
- Cash out early on 3-mines: high probability of safe clicks means low per-click EV pump.
- EV-optimal stop is purely variance preference — 1% edge is flat regardless of stop point.
- For high-volume play, 3-mines is the bankroll-friendliest config (longest expected runtime).
- Bankroll math: at 1% edge, a $100 bankroll on 3-mines first-click-only bets has expected runtime of ~10,000 clicks.

Frequently asked questions
- Is 3 mines a good Mines strategy?
- 3 mines minimises variance — frequent small wins, infrequent losses. Long-run EV is identical to other mine counts (flat 1% house edge). Pick based on whether you want lower variance (3 mines) or higher per-click rewards (15+ mines).
- What's the max payout on 3 mines?
- Gross multiplier maxes around 32x at all-22-safe-tiles cleared. Real cap is the per-game payout cap configured in env (typically $2,500). Most players cash out well before all-clear.
- Should I always pick the same 3 tiles?
- No advantage. Mine placement is randomised per round from HMAC-SHA256(seed, nonce). Tile-pattern preference is variance-neutral.
