How to Play Minesweeper
Your goal is to reveal every safe square without opening a mine. A revealed number tells you how many mines touch that square, including diagonally. Use those clues to identify safe squares and mine locations.
- Reveal a square: left-click it, tap it, or focus it and press Enter.
- Mark a mine: right-click, press and hold, or press F on a focused square.
- Clear around a number: click an open number after placing the matching number of flags.
- Win: open every square that does not contain a mine.
Your first reveal is always safe. When possible, the surrounding eight squares are safe too, giving you a useful opening area.
Learn by making a move
Use a clue, place a flag, then open a safe square. This short exercise explains each move as you make it.
Two moves. One useful rule.
A is already correctly flagged. Use the numbers to work out C, then B. This is a complete 2 × 3 practice board.
Step 1 of 2
Which covered square must be a mine? Select it to place a flag.
Select squares to answer the prompt. Mistakes are safe here.
Read the solution and reasoning
- C must be a mine: the bottom-left 1 touches C and two open squares. C is its only possible mine.
- B is safe. The middle-right 2 already touches the two correctly flagged mines, A and C, so its other neighbor B cannot be a mine.
Count the covered neighbors. When all the mines touching a number are correctly flagged, its other neighbors are safe.

Mouse, Touch, and Keyboard Controls
On a computer, use the classic left-click and right-click controls. Choose Reveal or Flag above the board to set what a click or tap does. On a touchscreen, holding a square also marks it. Keyboard players can move with the arrow keys, press Enter or Space to reveal, press F to mark a square, and press F2 to restart.
Use Cell size for smaller or larger squares. On wide boards, scroll the minefield sideways; the counters and restart button stay visible. See all controls and try chording →
Minesweeper Strategy for Beginners
- If a number already touches that many flags, its other covered neighbors are safe.
- If a number has the same number of covered neighbors as its remaining mines, flag those neighbors.
- Start with certain moves and postpone guesses until no logical move remains.
- Work from open edges where fewer unknown squares touch each clue.
- A flag is only a note; an incorrect flag can block a safe move, so recheck your count.

Some random boards need a guess. Before guessing, look for a certain move elsewhere or compare neighboring clues. These guides show you what to look for.
