minesweeper rules and strategy for beginners

The goal of Minesweeper

Win Playfun Minesweeper by revealing every square that does not contain a mine. A revealed number tells you how many mines touch that square horizontally, vertically, or diagonally. A blank square has no adjacent mines and opens its connected safe area automatically.

Flags are reminders. You do not have to flag every mine to win; revealing all non-mine cells is enough.

Choose a board

Playfun has three sizes:

• Easy: 9 × 9 with 10 mines.
• Medium: 12 × 12 with 24 mines.
• Hard: 14 × 14 with 40 mines.

The timer starts on your first reveal. Mines are placed after that click, and the first square plus all of its immediate neighbours are kept safe. This creates a useful opening area instead of allowing a first-click loss.

Reveal and flag controls

Click or tap a covered square to reveal it. On a computer, right-click a covered square to place or remove a flag. On a touch screen, press and hold for about a third of a second.

You can also switch the pickaxe button into flag mode. While flag mode is active, a normal tap places or removes a flag. The Mines counter shows the total mine count minus the number of flags you have placed; it is an aid, not proof that every flag is correct.

The two rules that solve most positions

Focus on a revealed number and count two things: adjacent covered squares and adjacent flags.

Rule 1: all remaining covered neighbours are mines. If a 2 already touches one flag and has only one other covered neighbour, that covered square must be the second mine.

Rule 2: all remaining covered neighbours are safe. If a 2 already touches two flags, every other covered square around that 2 can be revealed.

Apply the rules repeatedly. Each safe reveal may expose a new number, and each new flag may unlock several safe squares.

Work from the open boundary

The useful information sits where revealed numbers meet covered cells. Scan that boundary from one end to the other instead of clicking isolated squares in the middle of an unknown area.

For each number:

1. Count its neighbouring flags.
2. Count its other covered neighbours.
3. Apply one of the two rules if the counts match.
4. Move to the next number, then rescan after the board changes.

This systematic pass catches deductions that are easy to miss when you stare only at the most crowded cluster.

Recognize a simple 1-2 pattern

Suppose a straight boundary shows a 1 beside a 2, with an overlapping group of covered cells. If the 1 limits its group to one mine and the 2 needs one additional mine outside that shared group, the outside cell is forced.

Do not memorize a picture without checking the surrounding squares. Corners, existing flags, and already revealed cells change which cells belong to each number. The reliable method is always to compare the two neighbour sets.

Flag only proven mines

An incorrect flag can make a number appear satisfied and cause a chain of bad reveals. Place a flag when a number rule proves the mine, not merely because a square feels likely.

If the board becomes contradictory, review flags first. Playfun marks an incorrect flag with an X only after a mine is hit, so during play you must verify flags against the visible numbers yourself.

When a guess is unavoidable

Some random mine layouts can leave a position with no forced move. Before guessing, scan the entire boundary, including distant sections; a deduction elsewhere may provide the flag count you need.

If no deduction exists, choose a covered square with the lowest apparent mine risk and one that is likely to reveal a large area. Avoid a square that several high numbers share. A guess is a last resort, not the default way to advance.

Quick answers

Can the first click hit a mine?

No. Playfun protects the first selected square and its eight-cell surrounding area where those neighbours exist.

Do flags make me win?

No. You win when every non-mine square is revealed. Playfun then flags any remaining mines automatically.

What does a zero mean?

A zero has no adjacent mines. Playfun displays it as a blank and automatically reveals connected safe blanks and their numbered boundary.
