Minesweeper: A Space Odyssey

Minesweeper: A Space Odyssey is played by revealing squares of the grid, typically by clicking them with the mouse. If a square containing a mine is revealed, the player loses the game. Otherwise, a digit is revealed in the square, indicating the number of adjacent squares (out of the possible eight) that contain mines. If this number is zero then the square appears blank, and the surrounding squares are automatically also revealed.
