Balance is a tilt puzzle game that can be played by simply tilting a laptop. Besides the mouse and trackpad, the game can make use of the accelerometers built into all Apple notebooks, including the various MacBook, PowerBook and iBook models.
Balance requires both puzzle solving and hand-eye coordination skills without any time pressure as players tilt the playfield to guide one or more balls between various 3D obstacles to their destinations. The game has 75 levels that are continuously expanded by downloadable level upgrades. Players can share their best times over the internet along with recordings of their sessions for others to watch.
