Minesweeper · Game guide
Play now ↗Rules and controls
Numbers show how many mines touch a cell in the eight neighboring directions. Reveal every safe cell to win; revealing a mine ends the board. The first click and its neighbors are safe. Right-click, press F or use Flag mode to mark suspected mines.
Beginner strategy
Start near the center to open a wider area. Compare overlapping number neighborhoods: when a number already touches that many flags, its other closed neighbors are safe; when its remaining mine count equals its closed neighbors, all are mines. Solve every certain move before guessing.
Solo, shared-device and online play
Gomoku, Go, chess, janggi, Othello and tic-tac-toe offer computer opponents, two-player play on one device, invitation-link online play and random matchmaking. Random matchmaking waits for another person; an immediate match is not guaranteed. Party games differ in player counts, controls and online support.
