What do the numbers mean in Minesweeper?

A number shows exactly how many mines are in the eight surrounding squares, including diagonal neighbors.

Do you have to flag every mine to win?

Usually no. You win by revealing every safe square. Flags simply help you track squares you believe contain mines.

Is Minesweeper always solvable without guessing?

Not every randomly generated board is guaranteed to be solvable by logic alone. Some positions can require a probability-based choice.

How to Play Minesweeper: Rules and Patterns for Beginners

The goal of Minesweeper

The goal is to reveal every safe square without opening a mine. A revealed number tells you exactly how many mines touch that square, including diagonally. A 1 touches one mine, a 2 touches two, and so on.

Blank squares have no adjacent mines. Opening one usually reveals a connected safe area automatically, which gives you the numbered boundary clues needed to continue.

Reveal, flag, and check

Reveal a square when the clues prove it is safe. Place a flag when the clues prove a mine must be there. Flags are notes for you; they do not solve the board by themselves, so avoid guessing with them.

After every reveal, look again at nearby numbers. A single safe square can complete one clue, which completes another, producing a chain of deductions.

The two basic rules

For example, if a 1 touches one flagged square and two covered squares, both covered squares are safe. If a 2 touches one flagged mine and only one other covered square, that remaining square must be the second mine.

If a number already touches that many flagged mines, every other covered neighbor is safe.
If a number has exactly as many covered neighbors as mines still missing, every covered neighbor is a mine.

Read overlapping clues

Most useful deductions come from comparing nearby numbers. Suppose one clue says that one of two covered squares contains a mine. A neighboring clue says that one of those same squares plus a third square contains one mine. The third square must be safe because the shared pair already accounts for the mine.

You do not need to memorize every named pattern. Ask two questions: which covered squares does each number see, and how many unmarked mines does it still need? Comparing those sets produces the same logic.

Common beginner mistakes

Treating a flag as confirmed when it was only a guess.
Forgetting that diagonal squares count as neighbors.
Looking at one number in isolation instead of comparing it with the next clue.
Continuing in a complicated area when another edge has an obvious safe move.
Moving too quickly after a large blank area opens and reveals several new clues.

What to do when you seem stuck

Scan the entire boundary between revealed and covered squares. Start with numbers that have the fewest covered neighbors, because they are easiest to resolve. Recount flags and remember to subtract confirmed mines from each number.

Some traditional Minesweeper boards eventually force a guess. When that happens, prefer a square that opens more information and avoid a square that several high-number clues make especially risky. Sweeple Sprint uses a compact board, so slowing down to verify each clue is often more valuable than tapping quickly.
