How to Play
Minesweeper is a logic game where you clear a grid of hidden cells without detonating any mines. Numbers reveal how many mines are adjacent to that cell.
- Left-click (or tap) to reveal a cell
- Right-click (or long-press) to place a flag on a suspected mine
- Chord-click a numbered cell with the correct number of adjacent flags to reveal all remaining neighbors at once
- The first click is always safe and never a mine
- Clear all non-mine cells to win
Difficulty Levels
- Beginner — 9x9 grid with 10 mines
- Intermediate — 16x16 grid with 40 mines
- Expert — 16x30 grid with 99 mines (scrollable on mobile)
Tips
- Start by clicking near the center for the best chance of opening a large area
- If a "1" cell has only one unrevealed neighbor, that neighbor is a mine — flag it
- Use chord-clicking to speed up your game once flags are placed
Frequently Asked Questions
Is the first click in Minesweeper always safe?
Yes. The first cell you click is always safe and will never be a mine. The board is generated after your first click to guarantee this.
What does chord-clicking do?
Chord-clicking a numbered cell that already has the correct number of adjacent flags will automatically reveal all remaining unrevealed neighbors, speeding up gameplay.
How do I place a flag on mobile?
On mobile devices, long-press a cell to place or remove a flag instead of a right-click.
What are the three difficulty levels?
Beginner is a 9x9 grid with 10 mines. Intermediate is 16x16 with 40 mines. Expert is 16x30 with 99 mines, which scrolls horizontally on mobile.
Are best times saved?
Yes. Your best completion time for each difficulty level is saved locally in your browser automatically.
About
Minesweeper was first included with Microsoft Windows 3.1 in 1992 and became one of the most-played computer games in history. Originally designed to teach mouse controls, it evolved into a competitive speed game.
Our version features a timer, stats tracking with best times per difficulty, and a responsive design. The expert board scrolls horizontally on mobile devices so you can play at full size.
From the build: the hardest part of porting Minesweeper to touch was the right-click problem. Mouse users right-click to flag, but on a phone every interaction is a tap. We landed on a 250ms long-press threshold after testing on a handful of Android and iOS devices — quick enough to feel responsive, slow enough that it never fires when you're just scrolling past a cell. The Expert board kept the original 16x30 grid instead of being downscaled, because compressing it to fit the screen would have broken the muscle memory of long-time players. So it scrolls instead.
