Puzzle Board
Select Difficulty
On a phone, choose Reveal or Flag, then tap a cell. On a computer, right-click to flag.
How to Play
Reveal every safe cell without opening a mine. Each number tells how many mines touch that cell horizontally, vertically, or diagonally. A blank revealed cell has no neighboring mines and automatically opens the connected safe area.
Choose Reveal to open cells. Choose Flag to mark or unmark suspected mines. On a computer, you can also right-click a cell to flag it.
Use the numbers for deduction. If a 1 touches only one unrevealed square, that square must contain a mine. If a 2 already touches two known mines, its other neighboring cells are safe.
Your first reveal is always a zero and opens a useful safe area. Every generated board is checked by a logical solver and can be completed without guessing.
Keyboard: use arrow keys to move, Space or Enter for the selected action, and F to toggle a flag.
