The player begins each level with ten balls (twelve on the non-Touch iPod version) to clear the orange pegs, but may earn more by landing the ball in the ball catcher, or by earning high scores on single shots. Struck pegs are also removed if the ball is stuck on them.
Pegs light up when hit, and once the ball either falls through the bottom of the screen or is caught by the ball catcher that moves back and forth along the bottom in a fixed manner, the pegs will be removed.
