Minesweeper

What is Minesweeper?

Minesweeper is the classic single-player logic puzzle that shipped with Microsoft Windows for decades. The board hides a number of mines. Reveal a cell to expose either a number (showing how many mines touch that cell) or — if you're lucky — an empty area that cascades open. Detonate a mine and the game ends instantly. Reveal every safe cell to win.

How to Play

1. Click a cell to reveal it. Your first click is always safe — mines are placed afterwards, never under or next to your starting spot.
2. Read the numbers. Each number tells you exactly how many of the 8 surrounding cells contain a mine.
3. Right-click or long-press a hidden cell to mark it with a flag when you're sure it's a mine.
4. Chord click: Click on a revealed number whose flag count matches it to instantly reveal all surrounding unflagged cells.
5. Win by revealing every non-mine cell. The timer stops the moment you finish.

Difficulty Levels

• Beginner: 9×9 grid, 10 mines — perfect for warming up.
• Intermediate: 16×16 grid, 40 mines — the standard challenge.
• Expert: 30×16 grid, 99 mines — the canonical Minesweeper test of skill and speed.

Tips & Strategy

• Trust the numbers. A "1" touching a single hidden cell means that cell is the mine.
• Open corners first. Edges and corners limit the directions a mine can hide.
• Use chord clicks aggressively. Once you're confident in your flags, chord-clicking opens whole pockets in one tap.
• Pause before guessing. Most positions are deducible. If you must guess, pick a cell with the lowest neighbor mine ratio.
• Practice on Beginner. Speed comes from pattern recognition, not just risk-taking.
