How to play Minesweeper
-
Pick a level
Beginner (9 × 9, 10 mines), intermediate (16 × 16, 40 mines), expert (30 × 16, 99 mines) or a grid in the size you like.
-
Uncover squares
Click or tap a square: the number tells you how many mines touch it. Put a flag on the ones you know are mined (right-click, long press or flag mode).
-
Clear the whole grid
You win when every square without a mine is open. Your time is saved and compared with your best for that level.
A Minesweeper that feels right on every screen
Safe first click
Your first click never lands on a mine and always opens an area to get you started, just like the original game.
Made for phones
Long press to place a flag, a flag mode button, and buttons to zoom the grid in and out and drag it around. Expert switches to 16 × 30 on a narrow screen.
Chording in one click
Click a number that already has its flags: its remaining neighbors open at once, like the double-click in the classic desktop version.
Records and resume
Best times per level, games played and won, current streak. Your game is saved and pauses when you leave the tab.
Minesweeper rules
Minesweeper is played on a grid of hidden squares, some of which hide a mine. When you uncover a square without a mine, it shows a number: how many mines are in the eight squares around it. A blank square (zero) has no mined neighbors, so it automatically opens all of them, which can clear a big area with a single click. The goal is to open every square that has no mine without ever touching one. Flags are reminders: you place them on squares you know are mined, and the mines-left counter drops with each flag. The optional question mark lets you mark a square you are unsure about.
Levels: beginner, intermediate, expert
The three classic levels are kept exactly as they were: beginner is 9 × 9 with 10 mines, intermediate is 16 × 16 with 40 mines, and expert is 30 × 16 with 99 mines. On a phone held upright, the expert grid is turned into 16 columns by 30 rows so it stays readable, with the same 99 mines. The custom level lets you choose the width, the height and the number of mines. The mine count is capped so your first click always has room: the square you touch and its neighbors are guaranteed to be mine-free unless the grid is almost full. Best times are kept for the three classic levels; a custom grid has no record because its difficulty keeps changing.
Tips to win faster
Start with the edges and corners of the opened area: a 1 touching only one hidden square means that square is a mine. When a number already has as many flags as mines around it, all its other neighbors are safe: click the number to open them at once. That is chording, the move that saves the most time. Classic patterns help too: a 1-2 along a wall puts a mine on the square touching only the 2, and a 1-2-1 in a row puts mines at both ends. Only guess as a last resort, and pick the least risky square. To beat your records, skip flagging everything: only the flags you need for chording save seconds.
Playing Minesweeper on a phone or tablet
With no right mouse button, touch screens give you two ways to place a flag: a long press on a square, or the flag mode button that swaps the role of a simple tap. Either way, tapping a number that already has the right count of flags opens its neighbors. On big grids, the plus and minus buttons enlarge the squares so you can aim accurately, and you drag the grid with your finger to move around. The timer stops as soon as you switch tab or app, and the game picks up where you left off when you come back to the page.
Frequently Asked Questions
How do I place a flag on my phone?
Long press the square, or turn on the flag mode button: a simple tap then places a flag instead of uncovering the square. Long pressing again, or flagging the same square again, removes it.
Can my first click hit a mine?
No. Mines are placed after your first click, which is always safe and opens a starting area. Only a custom grid that is almost entirely mined can shrink that area down to the square you touched.
What is clicking a number for?
That is chording. If you have placed as many flags around a number as it shows, clicking it opens all its other neighbors. Careful: if one of your flags is misplaced, a mine goes off.
Where are my records saved?
In your browser, on this device only: nothing is sent to or stored on our servers. Clearing the site data or switching browsers erases your records. A button also lets you reset them.
Why does the timer stop when I switch tabs?
So you are not penalized: the game pauses as soon as the page is hidden, and the grid stays covered until you press Resume.
Can I choose the grid size and number of mines?
Yes, with the Custom level: from 5 to 40 columns and 5 to 40 rows, with any number of mines up to the grid size minus nine squares.
