How to Play Minesweeper

Minesweeper hides mines under a grid of covered squares - 10 on the Beginner board, 40 on Intermediate, and 99 on the huge Expert field. Left-click a square to reveal it. A revealed number tells you exactly how many of its eight neighbors hide a mine; a blank square has no adjacent mines and automatically clears its whole neighborhood. Right-click (or long-press on touch screens) to plant a flag on a square you believe is mined. Your first click is always safe, so dig in anywhere.

You win by revealing every square that isn't a mine - flags are just bookkeeping. Click a number whose flags are already accounted for and the game "chords", instantly revealing all its remaining neighbors. The counter on the left tracks mines minus flags, and the timer on the right records your solve. Win, and your time lands on the fastest-times leaderboard.

Playing Minesweeper on PlayVersusAI

The Windows classic, with three board sizes from beginner to expert. Left-click to reveal a square, right-click to flag a suspected mine, and each revealed number tells you how many mines touch that square. Clear every safe square to win.

Two quality-of-life rules that the original got right and many clones get wrong are implemented here. Your first click is always safe — the board is generated after you click, so you can never lose on move one. And chording works: once a numbered square has the right count of flags around it, clicking it reveals all remaining neighbours at once, which is where all the speed in competitive Minesweeper comes from.

Difficulty here means board size and mine density rather than an opponent. Beginner is a gentle introduction, intermediate is the standard practice board, and expert is the one the world records are set on.

Mistakes That Lose Games

Minesweeper Questions

Can I lose on the first click?
No. The mines are placed after your first click, so the opening square is always safe and usually opens a useful area.
What is chording?
Clicking a revealed number that already has the correct number of flags adjacent to it, which reveals all its remaining unflagged neighbours in one action. It is the main speed technique in the game.
Do I ever have to guess?
Occasionally, yes. Some board configurations produce genuinely ambiguous positions with no logical resolution. They are rarer than people assume, though — most apparent guesses are solvable with a careful look at overlapping numbers.
