Flag Sweeper

How to play

Click a square to reveal it. Numbers show how many mines touch that cell (diagonals count). Right-click (or long-press on mobile) to place a flag on a suspected mine. Clear every non-mine cell to win.

Tips & strategy

When a revealed number equals the flags already around it, every other touching cell is safe to open. When the unopened cells around a number equal that number minus its current flags, the rest must all be mines. Cascade the two rules around the edges and the board opens up fast.

Good for

• A classic logic-only brain break.
• Trainer for deduction and pattern spotting.
• Satisfying replay value — every board is new.

Frequently asked questions

Is the first click always safe?

Yes. If the first square you open would be a mine, the mine is moved before the board is revealed — standard minesweeper rules.

Can I play on mobile?

Yes. Tap to open, long-press to toggle a flag, or use the Flag button to switch mode.
