Move around the blocks to capture the flag, but don’t fall in the water. It’s a race against time and drowning.
The sapper moves with the help of arrows. The block he moves through disappears. When the sapper gets an empty field or the field with non-activated bomb, the sapper loses a life. As the number of blocks decreases, it will be harder and harder 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.
