How scoring works

A clean clear earns a difficulty base plus a bounded speed bonus. Beginner, Intermediate, and Expert have progressively larger bases and par times. Hitting a mine or restarting the same layout locks that attempt’s score at zero; ordinary undo and flagging are free.

How Minesweeper works

A number tells you exactly how many mines touch that square—including diagonals. Reveal every non-mine square to win; flags help you reason, but flags alone do not finish the board.

A Minesweeper flag and chord exampleA revealed one touches one flagged mine. The other adjacent covered squares are therefore safe and can be opened together by chording the one.1One flag satisfies the 1.Chord the 1 to open the other neighbors.
  1. Read all eight neighbors.A 1 touches exactly one mine; a 3 touches exactly three. Diagonals count.
  2. Flag mines, reveal safety.Use Flag for squares you believe are mines. Open safe squares; a zero automatically opens its surrounding empty area.
  3. Chord satisfied numbers.When a revealed number touches the same number of flags, reveal or tap that number to open every adjacent unflagged square at once. A wrong flag can make a chord hit a mine.

Your first reveal is safe. Every standard board can be solved without guessing.
