[[File:三种球.jpg|thumb|The appearance of three types of ball (from left: paper ball, wooden ball, and stone ball).]]
'''Ball''', or called the '''player ball''', is the core of [[Ballance]] and the only element that can be controlled by the player directly. The mean diameter of every type of ball is 4 meters (0.8 units): while the shapes of wood ball and stone ball are perfectly round, the paper ball is irregular, with its maximum width being 5 meters (1 unit). By using [[transformer]]s the current ball type can be changed.
