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. As the number of blocks decreases, it will be more and more hard for you to reach the block you need. In this case there are two supplementary keys to help you - Z (or End) and X (Or PgDn). You may revolve the line with your sapper to the left or to the right. One more useful feature is connected to playing field organization. When your sapper leaves the playing field at the left he appears at the right side. If he leaves at the bottom he will appear at the top and vice verse. From the 5th level the non-rotating blocks will appear.
