How to Play Minesweeper: Complete Beginner to Advanced Guide (2026)

Rules in 60 Seconds

Minesweeper is played on a grid of covered cells. Some cells hide mines, others are safe. You win by uncovering every safe cell without detonating a mine. Left-click to reveal a cell. If it's safe, it shows a number (1–8) telling you how many of its adjacent cells contain mines. If it's blank (no adjacent mines), it automatically expands to reveal its neighbors. Right-click to place a flag marking a suspected mine — flagged cells cannot be accidentally clicked. The game ends immediately if you click a mine. The game ends in victory when every non-mine cell is revealed.

Reading the Numbers

Each number is a precise constraint about its surrounding eight cells (up, down, left, right, and all four diagonals):

• 1 → Exactly 1 mine in adjacent cells
• 2 → Exactly 2 mines in adjacent cells
• 3 → Exactly 3 mines in adjacent cells
• 4 → Exactly 4 mines in adjacent cells

The key mental move: if a number's mine count equals the number of unrevealed adjacent cells, all those cells are mines — flag them all. If a number's mine count equals the number of flags already placed adjacent to it, all remaining unrevealed adjacent cells are safe — click them. This logical two-step resolves the majority of every Minesweeper board.

Where to Click First

Always click near the center of the board for your first move. Minesweeper guarantees the first click is never a mine, and clicking in the center maximizes the area that opens up — central cells have eight neighbors, while edge cells have five and corner cells only three. A large opening on your first click gives you far more numbers to work with and dramatically reduces the number of uncertain cells you'll face.

Flagging Strategy

Flagging is both a memory aid and a safety mechanism. Use flags when you've logically confirmed a cell contains a mine — not as a guess. The discipline: only flag what you know for certain. Random flags confuse your own reasoning and can lead you to incorrectly satisfy number constraints, causing you to click mines you would have otherwise avoided.

An advanced technique used by speed runners: Chord clicking. When a numbered cell already has exactly the right number of flags adjacent to it, you can middle-click (or double-click) that number to automatically reveal all its remaining unrevealed neighbors simultaneously. This speeds up board clearing enormously in areas where mines are already identified.

Common Patterns to Memorize

The 1-2 Pattern

When a 1 and a 2 are adjacent along an edge, and the 1 has only two unrevealed neighbors while the 2 shares one of them — the cell that the 2 sees but the 1 doesn't must be a mine, and the cell they share must be safe. This is one of the most frequently recurring patterns in Minesweeper.

The 1-2-1 Pattern

Three cells in a row showing 1-2-1 along the edge of the board form a classic pattern: the two corner cells (adjacent to the 1s but not the 2) are mines, and the center cell (below the 2) is safe. Recognizing this pattern instantly saves significant solving time on medium and hard boards.

The Saturation Rule

If all of a number's unrevealed neighbors are mines (i.e., the count of unrevealed adjacent cells equals the number shown), flag all of them. Conversely, if all adjacent mines are already flagged (flags equal the number), reveal all remaining unrevealed neighbors. These are the two fundamental operations that drive Minesweeper solving.

Handling 50/50 Situations

Some Minesweeper configurations produce genuine 50/50 situations where two cells could each be the mine, and no amount of additional logic can distinguish between them. In these cases, you must guess. Here's how to minimize the damage:

• Check if other board areas have more information before guessing. Solve everything else first — sometimes new reveals elsewhere constrain your 50/50.
• When you must guess, pick the cell that if safe, opens the most new area and gives the most information. This maximizes your benefit even when guessing correctly.
• On Easy mode genuine 50/50s are rare. On Expert they're common and accepted as part of the game.

Speed Tips for Better Times

Once you can reliably solve boards, improving your time comes from efficiency:

• Chord click constantly. Whenever a number's mines are flagged, chord-click it immediately rather than individually clicking each safe neighbor.
• Scan in patterns. Instead of checking each cell ad hoc, systematically scan row by row to ensure you don't miss quick resolves.
• Flag aggressively in opening phase. When large areas open up early, quickly flag obvious mines before processing numbers — this reduces mental load as the board fills.
• Don't flag everything. Experienced speed players often skip flags entirely and rely purely on memory for confirmed mines, since flagging itself costs time.
