The object of this game is to traverse the minefield without being blown up. There are 10 mines planted randomly in the field and you must negotiate your way from the top left corner to the bottom right without treading on one. Fortunately, you have a mine detector with you which will start registering a mine when it is less than five moves away. The number appearing in the top left corner of the screen indicates the proximity of a mine the higher the number the nearer you are. You can move in one of four directions by pressing the cursor movement keys 5 to 8.
