Corn cobs with ripe waxy kernels are strung on a long pipe. Your task is to cut them with a special ring-shaped knife. When you press the screen, the ring shrinks to the size of the pipe diameter and all the grains bounce off the pipe. But you should carefully monitor the differences in the pipe, it can either expand or narrow, and you must respond to this by either pressing the screen or releasing the mouse button. The task is to reach the finish ring by scoring the required number of points in the upper left corner. Points are cut grains and usually there is a margin on the pipe in case you don’t have time to cut everything in One Tube.
