The Ball-O-Tron is seen to the left of the playing screen in Peggle. Any balls the player earns go here until launched. The player will start off with 10 balls. (Except in certain challenges) The maximum amount of balls that it is possible to have at any one time (although this is highly unlikely) is 14. The player will receive warnings when they have not beaten the level and have only 3, 2, or just one ball remaining.
