Minefield
Reveal every safe cell and flag the mines. Three board sizes, a timer, and your best times stored in this browser.
How to play Minefield
The board hides a fixed number of mines. Tap or click a cell to reveal it. Numbers show how many mines touch that cell. Use the numbers to deduce which cells are safe and which hide mines.
Flag a cell when you are sure it is a mine. Reveal every non-mine cell to win. Hit a mine and the round ends.

Difficulty
- Easy — 9×9 with 10 mines. A quick warm-up.
- Medium — 12×12 with 22 mines. The default challenge.
- Hard — 16×16 with 40 mines. For players who like denser boards.
Tips
- Your first click is always safe; mines are placed after it.
- When a number matches the flags around it, the remaining neighbours are safe.
- When a number matches the unopened neighbours, they are all mines — flag them.
- Corners and edges give stronger constraints early on.
