As the player turns the steering wheel, the disc revolves and the ball drops into one of a
number of slots around it's circumference. As the disc continues to turn, when the ball
arrives at the top of the machine, it plops out onto the playfield. This system of ball
delivery is fine if you understand how it works. However, a novice player can get quite
infuriated by constantly turning the wheel from left to right, only to hear the sound of the
ball clanking around inside the machine!
