How to play Minesweeper

Click any cell to start. Your first click and the 8 cells around it never contain a mine, so you always open a nice clearing.
A number on an open cell tells you how many mines are in the 8 surrounding cells.
Mark cells you know are mines with a flag: right-click on desktop, or long-press (or switch to 🚩 Flag mode) on mobile.
Click a number that already has that many flags around it to open all its other neighbors at once. This is called chording.
Reveal every cell that is not a mine to win. Your time is saved as the best time for that difficulty.

Difficulty levels

Level	Board	Mines	Mine density
Beginner	9×9 (81 cells)	10	≈ 12.3%
Intermediate	16×16 (256 cells)	40	≈ 15.6%
Expert	30×16 (480 cells)	99	≈ 20.6%

These are the same sizes as classic Windows Minesweeper. On narrow phone screens, Expert is rotated to a tall 16×30 board with the same number of cells and mines.

Minesweeper patterns every player should know

The 1-1 pattern

When two 1s sit side by side along a wall, the first 1's mine must be in the two cells it shares with the second 1, so the third cell next to the second 1 is safe.

The 1-2-1 pattern

Along a wall (or an opened edge), 1-2-1 means the cells above both 1s are mines and the cell above the 2 is safe. It is the most common guaranteed pattern in the game.

The 1-2-2-1 pattern

With 1-2-2-1, the cells above the two 2s are mines and the cells above the outer 1s are safe.

Tips for faster times

You do not have to flag every mine. "No-flag" play, where you only click guaranteed-safe cells, is often faster.
Chording needs flags, though. Near big open areas, flag and chord to cut your click count sharply.
When logic runs out, compare the remaining mine count with the remaining cells and guess the cell that is least likely to be a mine and most likely to reveal new information.

FAQ

Can I hit a mine on my first click?

No. Mines are never placed on your first cell or the 8 cells around it, so the first click always opens an empty area.

How do I place a flag on my phone?

Press and hold a cell for about 0.4 seconds. Or tap the "👆 Reveal mode" button to switch to "🚩 Flag mode," and then a normal tap places a flag.

What happens when I click a number?

If that number already has the same number of flags around it, all the other unflagged neighbors open at once (chording). If one of your flags is wrong, you can set off a mine, so be careful.

Is Minesweeper always solvable without guessing?

Not always. With random mine placement you will sometimes face a true 50/50 that logic cannot solve. In those spots, use the remaining mine count to pick the cell with the lower odds.

What are good Minesweeper times?

Many casual players finish Beginner in under a minute and Intermediate in a few minutes. Expert often takes several minutes; competitive players are far faster, but your best time is the one to beat.

Where are my records saved?
