Rules
Opening a cell shows a number: how many mines touch it among its eight neighbors. Flag the cells you know are mines and open every safe cell to win. Opening a zero clears its neighbors automatically.
Patterns to know
- 1-1 on an edge: two 1s side by side along a wall often mean the third cell is safe.
- 1-2-1: along a wall, the mines sit across from both 1s and the middle is safe.
- 1-2-2-1: the mines sit across from the two middle cells.
When a number already has that many flags around it, click the number to open the rest of its neighbors at once. A wrong flag will set off a mine, so be sure.
Levels
Beginner is 9×9 with 10 mines, Intermediate is 16×16 with 40, and Expert is 30×16 with 99. On narrow screens Expert turns sideways to 16×30.
