Players join a harebrained professor and perform wacky experiments with the help of Goldbergian contraptions in Crazy Machines. The professor has forgotten how to perform his wild, physics-based experiments, so it's up to gamers to use a limited number of items to complete each machine. There are multiple solutions to every puzzle, the "Action" mode lets players use their stylus, touch screen, and microphone to maneuver the objects into place, and the "Sand Box" mode gives creative gamers the chance to design and share their very own puzzles with friends.
