Mines is a tap-to-reveal grid game. You choose how many mines are hidden on a 5 × 5 board, place a bet and tap tiles. A gem raises your multiplier; a mine ends the round and takes the stake. After every gem you can cash out or keep going. In crypto casino versions, the board is fixed by a server seed and client seed before you start, so each round is provably fair.
How a round works
- Set the number of mines (1 to 24).
- Place your stake.
- Tap a tile. A gem shows your new multiplier.
- Choose to cash out or open another tile.
- Repeat until you cash out or hit a mine.
The board fits a phone screen in portrait mode, and every action is a single tap, so a round can take seconds.
Low-mine setups for safer starts
Choosing fewer mines raises your chance of each safe tap. The table shows the maths on a 25-tile board. The multiplier column assumes a game with a 99% RTP; your game may pay slightly more or less, so check its rules screen.
| Mines | First tap safe | Chance of 4 safe taps in a row | Multiplier after 4 safe taps |
|---|---|---|---|
| 1 | 96% | 84% | about 1.18x |
| 3 | 88% | 58% | about 1.71x |
| 10 | 60% | 11% | about 9.17x |
Starting with 3 mines or fewer suits beginners who want longer sessions and steady, small wins. The trade-off is that each win is small.
Does the corner-tile tactic work?
A popular tip says corner tiles are safer because they border fewer squares. They are not. Mines are placed at random across all 25 tiles, so every tile has the same chance of hiding a mine: with 3 mines, that is 3 in 25, or 12%, for a corner just as for the centre. Neighbouring tiles play no part in where mines go.
Opening corners first does no harm, and some players like a fixed routine. Just do not raise your stake because you think a corner is safer.
Rising risk and cash-out timing
Each gem you find removes one safe tile, while the mines stay. So the chance that the next tap is safe goes down with every tap, and it falls fastest on boards with many mines. With 10 mines, your first tap is safe 60% of the time, and by the sixth tap it is 50%. This is the point some players call the volatility zone: where the next tap is close to a coin flip, or worse.
- Low-risk path: 3 mines, cash out after 3 to 4 gems (about 1.5x–1.7x at a 99% RTP).
- Medium-risk path: 3 mines, push to 5 or 6 gems (about 2x–2.35x), or play 5 mines and cash out once the chance of the next safe tap falls below a level you set in advance.
- High-risk path: play more mines and aim for 4x or more. With 10 mines, 3 gems pay about 5x, and you get there about one round in five. Keep the stake to 0.5% of your bankroll or less per round.
Splitting safe and risky play
Some players start on a safe board, such as 3 mines, and only after a couple of cash-outs move a small part of the profit to a risk board with 10 to 15 mines. If you do this, keep two separate amounts, your core bankroll and your high-risk money, and never top up the high-risk pot from the core. A note on your phone is enough to track both.
This changes how a session swings, not what it costs on average. Every board carries the same house edge.
Limits to set before you start
- Stop-loss: end the session if your bankroll drops 20%.
- Stop-win: if you are 50% up, bank at least half of the gain.
- Casino limits: most casinos let you cap deposits, losses or session time. Set them before you play; our responsible gaming page shows what to look for.
Key points to remember
- Fewer mines mean safer taps and smaller multipliers.
- No tile is safer than another; corner starts are a habit, not an edge.
- Cash out when the chance of the next safe tap drops below the level you chose.
- Fund risky boards from profit, never from your core bankroll.
- Verify boards with the provably fair tools when the game offers them.
- Set limits first. A strategy only works if you stay in control.
