Master Sweeper

Master Sweeper is a single-player puzzle. The object of the game is to clear an abstract minefield without detonating a mine.

The game is played by revealing squares of the grid by clicking or otherwise indicating each square. If a square containing a mine is revealed, the player loses the game. If no mine is revealed, a digit is instead displayed in the square, indicating how many adjacent squares contain mines; The player uses this information to deduce the contents of other squares, and may either safely reveal each square or mark the square as containing a mine.
