What Is Minesweeper?
Did you know Minesweeper is mathematically equivalent to some of the hardest problems in computer science? In 2000, mathematician Richard Kaye proved the game is 'NP-complete', meaning its logic scales to incredible complexity. The game requires you to uncover squares on a grid while avoiding hidden mines, using numbers that indicate how many mines touch each cell. You must rely entirely on logic and pattern recognition.

How to Play Minesweeper
- Click any cell to begin. The first click always reveals a safe area.
- Read the numbers on the revealed cells. A '1' means exactly one mine touches that cell.
- Deduce which adjacent cells hold mines based on overlapping number clues.
- Right-click (or long-press on mobile) to place a flag on suspected mines.
- Click all remaining safe cells to win. If you click a mine, the game ends immediately.
Basic Rules
- A number indicates the exact count of mines touching that cell horizontally, vertically, or diagonally.
- The first click guarantees a safe cell.
- You must flag suspected mines to keep track of them.
- You win only when you uncover every single non-mine cell.
- Clicking a mine ends the round instantly.
- Clicking a zero-mine cell automatically clears all adjacent safe cells.
Strategy Tips for Beginners
- Start by clicking near the center. You maximize your chances of opening a large blank area.
- Flag obvious mines first. If a '1' touches only one unrevealed cell, that cell is a mine.
- Clear satisfied numbers. If a '1' already touches a flagged mine, you can safely click all other cells touching that '1'.
- Memorize the 1-2-1 pattern. When you see 1-2-1 along a flat wall, the mines always sit next to the 1s.
- Memorize the 1-2-2-1 pattern. The mines always sit next to the 2s.
- Only guess when logic fails completely. Pick the cell with the lowest mathematical probability of holding a mine.
Real Examples of Gameplay
Basic Deduction
You see a '1' in a corner, touching only one hidden cell. You right-click to flag it. Now, any other numbers touching that flag have one of their mines accounted for.
The 1-2-1 Pattern
You uncover a flat row reading 1-2-1. You instantly flag the cells touching the 1s and safely click the cell touching the 2, knowing it must be clear.
Chording
You placed a flag next to a '1'. Instead of clicking the remaining safe cells one by one, you click both mouse buttons simultaneously on the '1'. This advanced move, called chording, instantly opens all surrounding safe cells.
Variations of Minesweeper
- Beginner (9x9, 10 mines): Small grid designed for learning core logic patterns.
- Intermediate (16x16, 40 mines): Standard board size offering balanced difficulty.
- Expert (30x16, 99 mines): Large grid requiring advanced pattern recognition and chording.
Why People Love Minesweeper
- The game provides absolute, logic-driven certainty.
- Clearing a massive blank area in one click feels highly rewarding.
- Matches progress quickly, taking seconds or minutes to complete.
- Speedrunning creates a competitive ceiling for advanced players.

Frequently Asked Questions
Is Minesweeper a game of skill or luck?
Minesweeper relies heavily on skill and pattern recognition. However, some board generations force a 50/50 guess at the end of the game when clues do not provide enough information. Advanced players memorize complex patterns to minimize guessing.
What is a good time for expert Minesweeper?
Completing the Expert grid (99 mines) in under 100 seconds shows high skill. The world record currently sits below 30 seconds. Beginners should focus on finishing the board before worrying about the timer.
Can I play Minesweeper on mobile?
Yes. We optimized the controls for touch screens. Tap to reveal a cell, and long-press to place a flag. You can easily navigate the grid on any phone.
