About Minesweeper
Minesweeper is the desktop-era classic that turns out to be a razor-sharp logic puzzle. Every number tells you how many mines touch that square; from those clues alone you deduce where it is safe to click and where certain doom sits. One wrong guess ends the round — one clean deduction chain feels fantastic.
Play Easy (9x9 with 10 mines), Medium (16x16 with 40), or Hard (24x16 with 99). Your first click is always safe, chording speeds up mid-game clears, and phones get a long-press plus a dedicated flag-mode toggle in place of a right mouse button. The timer and per-difficulty best times are saved locally — free, in your browser.
How to play Minesweeper
- Reveal squares by clicking or tapping; each revealed number counts the mines in its up to eight neighboring squares.
- Your first click is always safe and opens a starting area.
- Flag the squares you know hold mines — the counter shows how many mines remain unflagged.
- Chord to go faster: click a number that already has the right count of flags around it to reveal its remaining neighbors at once.
- Reveal every safe square to win; hitting a mine ends the game.
- Pick Easy, Medium, or Hard — best times are tracked separately for each difficulty.
Controls
- Left-click or tap to reveal a square.
- Right-click to plant a flag on desktop.
- On touchscreens, long-press to flag — or switch on flag mode so plain taps place flags.
- Click a satisfied number (flags equal its value) to chord-reveal the rest of its neighbors.
Tips & tricks
- Learn the 1-2-1 and 1-2-2-1 edge patterns — they resolve instantly and show up constantly.
- Work from corners and thin strips of numbers; fewer neighbors means stronger deductions.
- Flag only what helps you chord — over-flagging costs time, and wrong flags make chording lethal.
- When a guess is forced, count instead of vibing: pick the square with the lowest local mine probability.
Frequently asked questions
Can the first click in Minesweeper hit a mine?
Not here — the first click is always safe in our version, so start anywhere you like. Opening near the middle tends to reveal the most space.
What do the numbers in Minesweeper mean?
Each number counts the mines among its up to eight touching squares. A 1 with a single unrevealed neighbor marks a certain mine, and a number with all its mines flagged means its other neighbors are safe. Every deduction builds from that.
What is chording in Minesweeper?
Clicking a revealed number that already has exactly the right number of flags beside it. All remaining unflagged neighbors open at once — a huge speed boost, as long as your flags are right.
