What Is Minesweeper?
Minesweeper is a single-player puzzle game where the objective is to clear a rectangular board containing hidden “mines” without detonating any of them. It is a game of logic and deduction, similar to Sudoku (WikiHow, 2026). Each Minesweeper game starts out with a grid of unmarked squares. After clicking one of these squares, some squares will disappear, some will remain blank, and some will have numbers on them (WikiHow, 2026). It’s your job to use the numbers to figure out which of the blank squares have mines and which are safe to click (WikiHow, 2026).
The first square you click will never have a mine beneath it; clicking a square will clear off some of the board while numbering other squares (WikiHow, 2026). This guarantee allows you to start the game without fear of an immediate loss.
How to Play Minesweeper: Step-by-Step
Step 1: Understand the Controls
The mouse is the only tool you need to play Minesweeper (WikiHow, 2026):
- Left-click (Reveal): Click a square to reveal what’s underneath. If it’s a mine, the game ends. If it’s a number, it tells you how many mines are adjacent. If it’s blank, it clears a large area of the board (WikiHow, 2026).
- Right-click (Flag): Right-click a square to place a flag. This marks a square you believe contains a mine. Flagging helps you track which squares are dangerous and prevents accidental left-clicks (WikiHow, 2026).
- Middle-click / Double-click (Chord): On some versions, clicking both buttons or double-clicking a numbered square will reveal all adjacent squares if the correct number of flags are already placed. This is a time-saver for advanced players.
Step 2: Understand What the Numbers Mean
A number on a square refers to the number of mines that are currently touching that square (WikiHow, 2026). For example, if there are two squares touching each other and one of the squares has “1” on it, you know that the square next to it has a mine beneath it (WikiHow, 2026).
| Number | Meaning |
|---|---|
| 1 | Exactly 1 mine is in the 8 adjacent squares |
| 2 | Exactly 2 mines are in the 8 adjacent squares |
| 3 | Exactly 3 mines are in the 8 adjacent squares |
| 4 | Exactly 4 mines are in the 8 adjacent squares |
| 5 | Exactly 5 mines are in the 8 adjacent squares |
| 6 | Exactly 6 mines are in the 8 adjacent squares |
| 7 | Exactly 7 mines are in the 8 adjacent squares |
| 8 | Exactly 8 mines are in the 8 adjacent squares (all adjacent squares are mines) |
Example: If a square shows “3,” there are exactly 3 mines among the 8 squares touching it. If 2 of those adjacent squares already have flags, the remaining 6 squares contain exactly 1 mine.
Step 3: Start Playing
- Click a square anywhere on the grid. Your first click is always safe (WikiHow, 2026).
- Look at the numbers. Each number tells you how many mines are adjacent to that square.
- Use logic to deduce safe squares. If a “1” is touching only one unrevealed square, that square must be a mine — right-click it to place a flag.
- Left-click squares you are certain are safe. If a “1” is touching a flagged square, all other adjacent squares are safe to click.
- Continue until all non-mine squares are revealed. The game is won when all squares without mines are cleared and all mines are flagged (MinesweeperOnline, 2026).
How Does Minesweeper Work?
Minesweeper works by generating a grid of hidden mines and then calculating numbers for each square based on adjacent mines. When you click a square, the game checks if it contains a mine — if it does, you lose. If it doesn’t, the game reveals the square and any adjacent squares that are safe (WikiHow, 2026). If a square has no adjacent mines, the game automatically reveals all connected safe squares (this is called “flood fill”).
The grid sizes and mine counts vary by difficulty:
| Difficulty | Grid Size | Number of Mines |
|---|---|---|
| Beginner | 9×9 | 10 |
| Intermediate | 16×16 | 40 |
| Expert | 30×16 | 99 |
| Custom | Variable | Variable |
Minesweeper Strategies: How to Win
Strategy 1: Start in a Corner
Starting in a corner gives you fewer adjacent squares to worry about, making it easier to deduce mine locations from the numbers (MinesweeperOnline, 2026). A corner square only has 3 adjacent squares, compared to 8 for a center square.
Strategy 2: Use the “1-2-1” Pattern
When you see the pattern “1-2-1” in a row, the squares under the two “1”s are mines, and the square under the “2” is safe (MinesweeperOnline, 2026). This is a reliable pattern that works on edges.
Strategy 3: Use the “1-2-2-1” Pattern
When you see “1-2-2-1” along a wall, the squares under the two “1”s and the square between the “2”s are mines (MinesweeperOnline, 2026). The safe squares are under the first and last “2”s.
Strategy 4: Flag Mines to Avoid Accidental Clicks
Right-click to flag squares you suspect contain mines. This prevents accidental left-clicks and helps you track which squares are dangerous (MinesweeperOnline, 2026).
Strategy 5: Use the Chord Move
On most versions, if you double-click (or click with the middle button) a revealed number, and the number of flags around it matches the number, the game will automatically reveal all adjacent non-flagged squares. This is a huge time-saver.
Strategy 6: Look for Certainty Before Guessing
Minesweeper is a game of logic. Only click or flag squares when you are certain. Guessing is sometimes necessary in difficult situations, but try to exhaust all logical deductions first (MinesweeperOnline, 2026).

Troubleshooting Table
| Problem | Cause | Solution |
|---|---|---|
| You reveal a mine | You clicked on a square that contained a mine | The game ends. Learn from the experience and try again (WikiHow, 2026). |
| You can’t figure out where mines are | You may have missed a pattern or a logical deduction | Look for 1-2-1 or 1-2-2-1 patterns. Check if any numbers are “complete” with flags (MinesweeperOnline, 2026). |
| You accidentally left-click a flagged square | You missed the right-click | Flagging prevents left-clicks on flagged squares, so this shouldn’t happen if you’ve flagged correctly (WikiHow, 2026). |
| The game feels too hard | You may be on a difficult setting | Start with Beginner (9×9, 10 mines) to learn the patterns (MinesweeperOnline, 2026). |
| You can’t find Minesweeper on your computer | It’s no longer pre-installed on Windows | Download Microsoft Minesweeper from the Microsoft Store for free (WikiHow, 2026). |
Frequently Asked Questions
How do you play Minesweeper game?
Minesweeper is played by clicking squares on a grid. Left-click to reveal a square. If it’s a mine, you lose. If it’s a number, it tells you how many mines are adjacent. Use the numbers to deduce where the mines are and right-click to flag them (WikiHow, 2026). The goal is to reveal all non-mine squares.
What do the numbers mean in Minesweeper?
A number on a square refers to the number of mines that are currently touching that square (including diagonals). For example, a “3” means there are exactly 3 mines among the 8 adjacent squares (WikiHow, 2026).
How do you win in Minesweeper?
You win by revealing all non-mine squares and correctly flagging all mines. The game ends when all non-mine squares are cleared and all mines are flagged (MinesweeperOnline, 2026).
Is Minesweeper a game of luck or skill?
Minesweeper is a game of logic and skill. While the initial mine placement is random, success depends on your ability to deduce mine locations from the number clues. Guessing is sometimes necessary, but skilled players can often solve puzzles without guessing (MinesweeperOnline, 2026).
How do you play Minesweeper for beginners?
Start with Beginner difficulty (9×9 grid with 10 mines). Focus on understanding the numbers and flagging mines. Look for “1”s that only touch one unrevealed square — those are guaranteed mines. Practice on easy settings until you understand the logic (MinesweeperOnline, 2026).
