Tip: right-click (or turn on Flag mode) to mark a mine. Click a number with the right count of flags around it to clear its neighbors.

How to play Minesweeper

Minesweeper is a deduction puzzle. Hidden under the grid are mines; the rest of the squares are safe. Reveal a safe square and it shows a number — how many of its eight neighbors are mines. A blank square (zero) means none of its neighbors are mines, so the board opens up automatically. Use the numbers to reason out exactly where the mines are, flag them, and clear every safe square to win.

Controls

Left-click / tap — reveal a square.
Right-click (or turn on Flag mode, or long-press on touch) — plant or remove a flag.
Click a revealed number — if you've flagged exactly that many neighbors, it clears the rest (a "chord"). A fast way to open big areas — but only when your flags are right.
F — toggle Flag mode; N — new game.

Tips & strategy

Start in the open. Your first click is always safe and opens a blank region — work outward from its edges.
Read the 1s. A "1" touching a single covered square means that square is the mine. Flag it, then look at what that flag unlocks elsewhere.
Subtract overlaps. When two numbers share covered squares, compare them — the difference often pins down a mine or a guaranteed-safe square.
Chord to go fast. Once a number's mines are all flagged, click it to sweep the safe neighbors in one move.

About the difficulties

The three boards are the classics: Beginner (9×9, 10 mines), Intermediate (16×16, 40 mines), and Expert (30×16, 99 mines). The first click is always safe on every board, and your fastest clear for each is saved in your browser along with any game you leave unfinished.
