The object of game is to close all pipes on the board by press the arrow-block.
If you press the right-arrow-block, the pipe-part at the left will move to the middle; the middle will move to the right; and the right-pipe-part will move to the left.
The same count for the arrow-blocks which show the left, top and bottom.
