Mines
A logic puzzle on the seabed: open every safe cell and avoid the hidden vents.
How to play
Tap a cell to open it. To mark one, switch to the buoy, right-click, or press F. On a keyboard, choose with the arrows and open with Space. P or Esc pauses. When an open number has that many buoys around it, tap the number again to open the rest of its neighbors at once.
Rules and score
A number shows how many vents touch that cell, counting all eight neighbors. Open a vent and the game ends. The first field is 5×5 with 3 vents; after that fields are 6×6 with 5, 6, 7, then 8 vents. Air runs out over time (30 s for the first field). Clear a field to refill it for the next one (up to 60 s). No air — game over. Each cleared field scores 1 per vent.
Tips
- If a 1 has only one closed cell around it, that cell is a vent.
- Read two numbers side by side: the cells only one of them touches are often decided.
- Buoys plus opening from a number save far more air than single taps.
- Later fields refill less air. Bank some time early.
FAQ
- Will I ever have to guess?
- No. The first cell is always safe, and every field can be solved by logic.
- What if I place a wrong buoy?
- Tap it again to take it out. There's no penalty.
