Rolling a rock ball through a bridge made of planks will make the bridge collapse. The stone orb is extremely heavy, and can be accidentally rolled off an edge very easily, but this ball can easily push down boxes and bridges. It is the very first ball, used in the easy levels. The wooden ball is very stable and can be used for several puzzles in the game.
It can be transformed into a wood, rock, or paper ball.
In the game, the player can change the ball's material with special changers throughout the game's 12 levels. The gameplay is similar to Marble Madness: the player controls a ball via mouse and keyboard, moving it along a course while trying not to fall off the screen. It was developed by German studio Cyparade, published by Atari and first released in Europe on 2 April 2004. Ballance is a 3D puzzle video game for Microsoft Windows.
