What do the numbers mean in Minesweeper?
Every number on a Minesweeper board answers one question: how many mines am I touching? Master that and the whole game opens up.
The one rule to remember
A number tells you how many mines are in the eight squares surrounding it — up, down, left, right and all four diagonals. A 1 touches one mine; a 4 touches four. A blank square touches none, which is why blank areas open up automatically.
The number colours
Most Minesweeper versions colour-code the digits so you can read the board at a glance:
1 Blue
1 mine in the surrounding squares.
2 Green
2 mines in the surrounding squares.
3 Red
3 mines in the surrounding squares.
4 Dark blue / purple
4 mines in the surrounding squares.
5 Maroon
5 mines in the surrounding squares.
6 Teal
6 mines in the surrounding squares.
7 Black
7 mines in the surrounding squares.
8 Grey
8 mines in the surrounding squares.
Turning numbers into safe moves
- All mines found: if a number equals the count of its still-covered neighbours, every one of them is a mine — flag them.
- All mines flagged: if a number already has that many flags around it, all its other neighbours are safe to open (this is where chording shines).
- Compare neighbours: two adjacent numbers together often pin down a mine that neither could find alone — see Minesweeper patterns.

Frequently asked questions
What do the numbers mean in Minesweeper?
Each number tells you exactly how many mines are hidden in the eight squares immediately surrounding it. A 3, for example, means three of that square's neighbours are mines.
What does a blank square mean?
A blank (empty) square has zero neighbouring mines. Because it's completely safe all around, the game automatically reveals the connected blank area and its bordering numbers for you.
What is the highest number in Minesweeper?
The highest possible number is 8, because every square has at most eight neighbours. An 8 means all surrounding squares are mines — rare, but it happens on dense boards.
Why are the numbers different colours?
The colours are a traditional readability aid: 1 is blue, 2 is green, 3 is red, and so on. They help you scan the board quickly, but the colour carries no extra meaning beyond the digit itself.
How do I use the numbers to find mines?
Compare a number with its covered neighbours. If a number equals the count of its covered squares, they are all mines. If its mines are already flagged, every other neighbour is safe.
