hit a mine and you lose your stake.

What Is Mines?
Mines is a casino game developed by Spribe, inspired by the classic Minesweeper computer game. Players reveal tiles on a grid, avoiding hidden mines while building up a multiplier.
Unlike Minesweeper, there are no number clues to help you—mine placement is random and unknown. This makes Mines purely a game of chance with a single decision: when to cash out.
How Mines Works
- Choose number of mines: 1-24 mines hidden in a 5×5 grid (25 tiles)
- Place your bet
- Click tiles to reveal: Gems increase your multiplier, mines end the game
- Cash out anytime: Take your current multiplier before hitting a mine
- Hit a mine = lose: Your entire bet is lost if you reveal a mine
The more gems you reveal without hitting a mine, the higher your multiplier grows. The key decision is when to stop—push too far and risk losing everything.
Probability Mechanics
Mines probability is straightforward to calculate. For a 5×5 grid with 3 mines:
- First click: 22 safe tiles / 25 total = 88% chance of survival
- Second click: 21 safe / 24 remaining = 87.5%
- Third click: 20 safe / 23 remaining = 87%
Each successful reveal makes the next click slightly riskier (fewer safe tiles remain).
Example: 5 Mines on 25-Tile Grid
| Reveal # | Safe Tiles | Total | Survival Rate |
|---|---|---|---|
| 1st | 20 | 25 | 80.0% |
| 2nd | 19 | 24 | 79.2% |
| 3rd | 18 | 23 | 78.3% |
| 4th | 17 | 22 | 77.3% |
| 5th | 16 | 21 | 76.2% |
To survive 5 clicks with 5 mines: 0.80 × 0.79 × 0.78 × 0.77 × 0.76 = ~36%
RTP Explained
Mines has a stated RTP of 97% (3% house edge).
The multipliers you see are calculated to give the house its 3% edge over time. For example, if probability says a fair payout should be 2.00x, the actual game might offer 1.94x—the difference is the house edge.
Key Insight: The house edge applies regardless of how many mines
you choose or when you cash out. The 97% RTP is built into every multiplier offered.
Risk Levels (Mine Count)
You control risk by choosing how many mines to place:
| Mines | Safe Tiles | 1st Click Survival | Risk Level |
|---|---|---|---|
| 1 | 24 | 96% | Very Low (small multipliers) |
| 3 | 22 | 88% | Low |
| 5 | 20 | 80% | Medium |
| 10 | 15 | 60% | High |
| 20 | 5 | 20% | Extreme |
| 24 | 1 | 4% | Maximum (lottery-like) |
More mines = higher potential multipliers but lower survival probability. Neither setting is "better"—they're just different risk/reward profiles.
Responsible Play
Mines can feel like a skill game, but it's pure chance. To play responsibly:
- Set a budget and stick to it—don't chase losses
- Cash out early is a valid choice—there's no "optimal" number of clicks
- Understand variance: Short-term results can swing wildly from expected RTP
- Take breaks: The fast pace can lead to impulsive decisions
