About Minesweeper
Minesweeper is the classic logic puzzle that came pre-installed on Windows computers for decades. The board is a grid of hidden tiles, and a number of them hide mines. When you reveal a safe tile, it shows a number telling you how many mines are touching it — and you use those numbers to deduce, square by square, exactly where the mines are. Flag the mines, clear every safe tile, and you win. Click a mine and it's game over. It's pure deduction: no luck once you get going, just careful reading of the numbers.
This version is free, has three difficulty levels, a built-in timer, saves your best time per difficulty, and works on phone and desktop. No signup, no download, unblocked at school.
How to Play
- Left-click (or tap) a tile to reveal it.
- A revealed number tells you how many of the 8 surrounding tiles contain a mine. A blank tile means zero, so its neighbors auto-open.
- Right-click (or long-press on mobile) to plant a flag on a tile you believe hides a mine.
- Chord: click a revealed number that already has the right number of flags around it to instantly clear its remaining neighbors.
- Reveal every safe tile to win. Hit a mine and the round ends.
- Your first click is always safe — it never lands on a mine.
How to Read the Numbers
- A "1" with only one unrevealed neighbor means that neighbor is the mine — flag it.
- A number that already touches that many flags is "satisfied" — every other tile around it is safe to open. Use chording to clear them fast.
- Compare overlapping numbers. If a "1" and a "2" share tiles, the extra mine the "2" needs must be in the tiles only it touches. This pattern-matching is the heart of Minesweeper.
- Start in the corners and edges. They touch fewer tiles, so their numbers give cleaner information.
- Only guess when you have to. Most of the board can be solved with pure logic — guessing is a last resort when no certain move exists.

FAQ
How do you play Minesweeper?
Left-click tiles to reveal them. Each revealed number tells you how many mines touch that tile. Use the numbers to work out where the mines are, right-click to flag them, and clear every safe tile to win. Hitting a mine ends the game.
Is Minesweeper free?
Yes, completely free. No signup, no payment, no download. It runs in any modern browser on phone, tablet or desktop, with three difficulty levels and a best-time tracker.
What do the numbers mean in Minesweeper?
A number on a revealed tile is the count of mines in the 8 tiles directly around it. A "3" means exactly three of its neighbors are mines. A blank tile has zero mines around it, so the game automatically opens its neighbors for you.
How do you flag a mine?
Right-click a tile on desktop, or long-press it on a touchscreen, to place a flag. Flags mark where you think mines are and stop you from accidentally clicking them. The mine counter at the top shows how many are left to find.
Is the first click ever a mine?
No. Your very first click is always safe — the mines are placed after you click, avoiding that tile and the ones around it, so every game opens up a usable area to start deducing from.
Is Minesweeper unblocked at school?
Yes. It runs entirely in your browser with no plugins or downloads, so it plays on school Chromebooks, work computers and any device with a modern browser.
What is chording in Minesweeper?
Chording is clicking a revealed number that already has the correct number of flags around it. It instantly reveals all the remaining unflagged neighbors at once, letting you clear satisfied areas much faster than one tile at a time.
