The playing field consists of rectangular blocks, activated and non-
activated bombs and bonus flags. From time to time one of the bombs activates.
Your goal is to move your sapper to a block with the activated bomb
before its fuse stops burning.
The sapper moves with the help of arrows. The block he moves through disappears.
When the sapper gets to an empty field or to the field with non-activated bomb,
the sapper loses a life.
