There are several mines hidden in the playing field.
The number of mines is indicated by the number at the
bottom of the field. The object is to find out where
they are located.
To uncover a square, right click on it. This will
reveal the number of adjacent mines, if any. If you
expose a mine, it blows up and the game is over.
To mark a square as a mine, hold down the space bar
and right click on the square. To unmark a square, hold
down the space bar and right click on a square marked
with a flag. The mine counter at the bottom of the
field indicates how many mines are left to be found.
