01 — How to playClear the board, dodge the mines
Minesweeper is a logic puzzle. Every number is a clue; every flag is a note to yourself.
Click a square to reveal it
Your first click is always safe. If the square is empty, the whole empty area opens up at once.
Read the numbers
A number tells you exactly how many mines touch that square — up, down, sideways and diagonally. A 1 next to one covered square means that square is a mine.
Flag the mines
Right-click a square (or long-press it, or switch on Flag mode) to mark it with a flag. Flagging keeps count and stops you clicking a mine by accident.
Chord to open fast
Click a revealed number once its flags match — for example a 2 with two flags around it — and all its other neighbours open at once. Be careful: a wrong flag can blow you up.
Win by revealing every safe square
You win the moment the last safe square is revealed. You do not have to flag every mine, but good flagging makes the ending much easier.
02 — DifficultiesThree classic boards, plus your own
Beginner is a quick warm-up. Expert is a serious puzzle — 99 mines across 480 squares.
| Difficulty | Board | Mines | Good for |
|---|---|---|---|
| Beginner | 9 × 9 | 10 | Learning the game, quick rounds |
| Intermediate | 16 × 16 | 40 | Regular play, real patterns |
| Expert | 30 × 16 | 99 | Long games, serious puzzling |
| Custom | 9–30 × 9–24 | 10 to (squares − 10) | Your own challenge |
03 — StrategyFive patterns that win games
Corners have only three neighbours and edges have five, so the numbers there are easier to solve. Open from a corner whenever you can.
When a 1, a 2 and a 1 sit in a row along an edge, the mines are under the two squares beside the 2 — the squares next to the 1s are safe. It is the most common pattern in the game.
Four numbers in a row, 1-2-2-1: the mines are under the two squares beside the 2s. The squares beside the 1s are safe to open.
Flag every mine you are sure about, then click the numbers whose flags match. Chording opens whole areas in one click and is how fast players clear boards.
Some boards cannot be solved by logic alone. Guess where a wrong answer costs the least — a corner with a 50/50 chance beats a square that would end a long game.
04 — FAQQuestions, answered first
Is it free to play Minesweeper here?
Yes, it is completely free. There is nothing to buy, no account, and no limit on how many games you play. Your best times are saved in your own browser.
Do I need to download anything or sign up?
No. There is nothing to download and no sign-up. Just open the page, pick a difficulty, and click a square to start.
How many mines are on each board?
Beginner is 9 by 9 with 10 mines, Intermediate is 16 by 16 with 40 mines, and Expert is 30 by 16 with 99 mines. You can also build a custom board with 9 to 30 columns, 9 to 24 rows, and 10 up to 10 fewer mines than the number of squares.
Is the first click always safe?
Yes. Mines are only placed after your first click, and never on the square you clicked or on any of its neighbours, so your first click can never hit a mine.
What does a number mean?
A number tells you how many mines are hidden in the eight squares around it. A 1 means exactly one of its neighbours is a mine; a 3 means three of them are mines. Use the numbers together to work out where the mines are.
How do I flag a square on mobile?
Tap the Flag mode button (🚩) above the board, then tap squares to flag them; tap it again to go back to revealing. You can also long-press a square for about half a second to flag it. On a computer, right-click a square to flag it.
How do I win a game of Minesweeper?
You win by revealing every square that does not contain a mine. You do not have to flag all the mines, but flagging helps you keep track. Revealing a mine ends the game immediately.
Can I make my own board?
Yes. Choose Custom, set the width (9 to 30), height (9 to 24) and number of mines, then press Apply board. Custom games are timed like the others but do not save a best time.
