Hard to figure out at first, but works once you do.

This ball can also be used as a cue ball. It takes some time to figure out how to use it, and you have to be very careful to get the lines perfectly straight to really have the maximum benefits of what it is teaching you to do. Once you get the hang of it, you will be able to perform jumps AND learn where the cue ball will go after hitting the object ball.
