How to win at Minesweeper — pattern recognition, logical deduction, and strategies for clearing any board.

Minesweeper isn’t luck — it’s logic. Every number is a clue, and every clue eliminates possibilities. Once you learn the common patterns, boards that seemed impossible become straightforward.

The Fundamental Rule

Each number tells you how many mines are in its 8 adjacent cells. That’s the entire game. Everything else is deduction from this single rule.

Number Adjacent Mines
1 Exactly 1 mine in the 8 surrounding cells
2 Exactly 2 mines
3 Exactly 3 mines
Blank 0 mines — all 8 neighbors are safe

The Two Basic Deductions

Deduction 1: “All Mines Found”

If a number’s mine count is fully satisfied by flagged cells, all other adjacent cells are safe.

Example: A “1” with one flagged mine next to it → all other adjacent cells can be safely clicked.

Deduction 2: “All Remaining Are Mines”

If a number’s unflagged adjacent cells exactly equals its remaining mine count, all those cells are mines.

Example: A “2” with 3 adjacent cells revealed as safe, 1 already flagged, and 1 unknown → that unknown cell is a mine.

The 5 Essential Patterns

Pattern 1: The “1-1” Edge Pattern

When two 1s are adjacent along an edge (wall), the mine is between them if they share an unrevealed cell — or at the ends if they don’t share.

Pattern 2: The “1-2” Edge Pattern

Along an edge: a 1 next to a 2. The mine for the 1 is on the side away from the 2. The 2’s second mine is on its other side.

Pattern 3: The “1-2-1” Edge Pattern

Along an edge: 1-2-1. Mines are adjacent to each 1 (on their outer sides). The cells adjacent to only the 2 are safe.

Pattern 4: The “1-2-2-1” Edge Pattern

Mines are at the outer ends (adjacent to the 1s).

Pattern 5: The “1-1” Corner

When a 1 is in a corner with only 3 adjacent cells, and one is revealed, the mine is in one of the remaining two. If another number constrains one of those cells, you can solve it.

Step-by-Step Solving Method

  1. Click center to start — maximizes the opening area
  2. Scan for obvious flags — any number where all adjacent unknowns equal its count
  3. Scan for obvious safe clicks — any number that already has all its mines flagged
  4. Look for patterns along edges and walls
  5. Use elimination — if a mine must be in one of two cells, check if other numbers constrain which one
  6. When stuck, look at the bigger picture — combine information from multiple numbers
  7. If truly stuck, guess on a 50/50 — prefer the choice that opens more information

Advanced Techniques

Subtraction Method

When two adjacent numbers share some cells but not others, subtract the smaller from the larger. The difference tells you how many mines are in the non-shared cells.

Edge Analysis

Work along edges from the cleared area outward. Edge cells have fewer neighbors, making deduction easier.

Mine Counting

Track total mines remaining vs. unknown cells. On Expert (99 mines, 480 cells), as you reveal more cells, the remaining mine density changes — sometimes making end-game guesses more informed.

Difficulty Strategies

Difficulty Grid Mines Strategy Focus
Beginner 9×9 10 Practice basic deductions
Intermediate 16×16 40 Apply patterns, work from openings outward
Expert 30×16 99 Chain deductions, manage 50/50s, use mine counting

Common Mistakes

  1. Random clicking — Every click should be logically justified
  2. Ignoring patterns — Memorize the 5 key patterns; they cover 80% of situations
  3. Not flagging mines — Flags help track which mines are accounted for
  4. Only looking at one number — Most deductions require combining info from 2+ numbers
  5. Giving up on “stuck” boards — Step back, look at the whole cleared area, and look for constraints you missed
