What Do the Numbers Mean in Minesweeper?
Each number tells you how many mines are hiding in the 8 cells surrounding it.
That is the entire rule. A “1” means exactly 1 of its 8 neighbors is a mine. A “3” means exactly 3 neighbors are mines. A blank cell (no number) means 0 neighbors are mines.
Try it yourself: Play a free game on Minesweeper Blast and see the numbers in action. Every board is solvable by logic — no guessing.
Visual Explanation
Imagine a cell showing the number 2. It has 8 neighbors (up, down, left, right, and the 4 diagonals). Exactly 2 of those 8 neighbors contain mines. The other 6 are safe.
Your job: figure out which 2 are mines using the numbers from nearby cells.
Edge and Corner Cells
- A cell on the edge of the board has only 5 neighbors (3 are off the board)
- A cell in the corner has only 3 neighbors
This is why corners and edges are easier to solve — fewer neighbors means the numbers constrain mines more tightly.
The Number Colors
Each number has a specific color in classic Minesweeper:
| Number | Color | How Common |
|---|---|---|
| 1 | Blue | Very common |
| 2 | Green | Common |
| 3 | Red | Moderate |
| 4 | Dark blue | Less common |
| 5 | Dark red / maroon | Rare |
| 6 | Teal / cyan | Very rare |
| 7 | Black | Extremely rare |
| 8 | Grey | Almost never seen |
An 8 means every single neighbor is a mine — this requires a very dense mine arrangement and is exceedingly rare.
How to Use the Numbers
The Two Basic Rules
Rule 1: If a number equals its flag count → remaining neighbors are safe
If a “2” has 2 flagged neighbors, all other neighbors are safe. Click them (or chord the number to reveal them all at once).
Rule 2: If a number equals its unrevealed count → all unknowns are mines
If a “3” has only 3 unrevealed neighbors, all 3 must be mines. Flag them.
Putting Them Together
Play happens at the boundary between revealed and unrevealed cells. You scan the numbers along this boundary, applying the two rules above, flagging mines and revealing safe cells. Each new reveal gives you more numbers, which give you more deductions, which reveal more cells.
Examples
Example 1: Simple 1
A “1” on the edge of the board has 5 neighbors. 4 are already revealed. The 1 remaining unrevealed neighbor must be the mine. Flag it.
Example 2: Corner 2
A “2” in the corner has only 3 neighbors. 1 is already revealed (safe). The 2 remaining unrevealed cells must both be mines. Flag them both.
Example 3: Two Numbers Working Together
A “1” and a “2” are side by side, sharing neighbors. The “1” only needs 1 mine out of its neighbors. The “2” needs 2. By comparing which neighbors they share, you can often deduce exactly which cells are mines — even when neither number alone is enough.
This is the basis of Minesweeper patterns.
What About Blank Cells?
A blank cell (no number at all) means 0 of its neighbors are mines. When you click a blank cell, the game automatically reveals all its neighbors — since none are mines, they are all safe. If any of those neighbors are also blank, their neighbors are revealed too. This is called a cascade or flood fill.
Cascades are why clicking corners first is a good strategy — corners frequently produce blanks that cascade across large regions of the board.
