how to play sweeper

Sweeper is a free mine-clearing logic game. Every number tells you how many mines touch that square, counting diagonals. Open every safe square to win. Every board is checked by our solver before you see it, so it can always be cleared by logic alone, without a single guess.

1. The field opens itself at a safe spot. Start reading the numbers around the edge of the opening.
2. Tap a square to dig it. Hold it, or right-click with a mouse, to plant a flag where you know a mine is.
3. Tap a number whose flags are all placed to open the rest of its neighbors in one go.
4. Flag mode swaps the two: a tap flags and a hold digs. A press that slides off its square does nothing, so a swipe never digs by accident.
5. Open every safe square to finish. Hitting a mine adds 30 seconds and flags it for you; the clock stops while the tab is hidden.

Keyboard: Arrow keys move between squares, Enter or Space digs (or opens around a finished number), F plants or removes a flag, and Esc goes back to the menu.

tips

• A 1 touching exactly one closed square means that square is a mine.
• Compare neighbors: if a 1 and a 2 share all but one closed square, that extra square must be the second mine.
• Near the end, count the mines left. Sometimes the total settles the last few squares.
