How to Play
The basics
- Left-click a cell to reveal it.
- Right-click (or enable Flag Mode on mobile) to plant or remove a 🚩 flag on a suspected mine.
- Numbers show how many of the 8 surrounding cells contain mines.
- Your first click is always safe — mines are placed after it.
- Uncover a mine and the game ends. Reveal every non-mine cell to win.
Advanced tip
- Chord click: left-click a revealed number once the correct number of flags surround it — all remaining neighbours are revealed automatically.
- The mine counter shows mines remaining (flags subtracted). It can go negative if you over-flag.
History
The Minesweeper concept traces back to mainframe games of the 1960–70s, most notably Cube (1973) and Relentless Logic (1985), text-based games where players navigated mine-filled grids.
Robert Donner and Curt Johnson wrote the version bundled with Windows 3.1 in 1992. Its original purpose was to teach users mouse skills — especially right-clicking — which was unfamiliar to most PC owners at the time.
Microsoft included Minesweeper with every Windows release from 3.1 through Vista and 7, making it one of the most-played computer games in history, with an estimated 500 million plays per day at its 1990s peak.
Windows 8 (2012) replaced the classic game with a modern app adding touch support, Xbox Live leaderboards, and daily challenge puzzles. Today Minesweeper is available on every platform as a free browser game.
Tips & Fun Facts
Solving strategies
- Start in a corner or edge — fewer neighbours means faster deductions.
- If a number equals the count of unrevealed cells around it, all of them are mines — flag them immediately.
- The 1-2-1 pattern along a wall has a definitive solution: the two outer cells are safe, the inner cell hides a mine.
- On Expert, some positions require a guess — pick cells that minimize the probability of hitting a mine.
Did you know?
- The Expert world record is 31.133 seconds (Kamil Murański, 2010).
- Minesweeper was proven NP-complete by Richard Kaye in 2000 — deciding whether a board has a consistent solution is computationally hard.
- The game was named after the naval ships used to clear harbours of underwater mines.
- Windows XP's version added a custom board size mode, allowing up to 30×24 grids with up to 668 mines.
