Minesweeper
Play classic Minesweeper in your browser — Beginner, Intermediate, and Expert board sizes, flags, a timer, and a mine counter. Nothing is uploaded, it all runs on your device.
🔒 This tool runs entirely in your browser. Your files are never uploaded to a server.
Left click (or tap) to reveal a cell, right click (or long-press) to flag a suspected mine.
How it works
- Pick a board size — Beginner, Intermediate, or Expert — from the dropdown above the board.
- Left click (or tap) a cell to reveal it. A number shows how many mines touch that cell; a blank cell means none do, and reveals its neighbors automatically.
- Right click (or long-press) a cell you suspect hides a mine to flag it, keeping it from being revealed by accident.
- Clear every cell that isn't a mine to win. Revealing a mine ends the game and shows the full mine layout.
Board sizes
| Difficulty | Grid | Mines |
|---|---|---|
| Beginner | 9 × 9 | 10 |
| Intermediate | 16 × 16 | 40 |
| Expert | 30 × 16 | 99 |
FAQ
What are the three board sizes?
Beginner is 9×9 with 10 mines, Intermediate is 16×16 with 40 mines, and Expert is 30×16 with 99 mines — the same three sizes as the classic Windows Minesweeper.
Can my first click ever hit a mine?
No. Mines are placed only after your first click, avoiding that cell and its immediate neighbors, so the opening move always reveals a safe patch of the board rather than instantly ending the game.
What do the numbers on revealed cells mean?
Each number is the count of mines hiding in the up-to-eight cells touching it (including diagonals). A blank revealed cell means zero adjacent mines, which is why revealing one often clears a whole open area at once.
How do I flag a suspected mine?
Right-click a hidden cell on desktop, or press and hold it on a touchscreen, to mark it with a flag. Flagged cells can't be revealed by accident — flag them again the same way to remove the flag.
Does switching board size or refreshing keep my progress?
No — changing the difficulty or reloading the page starts a fresh board. Nothing about a game is saved or sent anywhere; it exists only in your browser tab while you're playing.
