Fans of Fantastic Contraption, Phun, or just about any physics-based sandbox game may want to sneak a peek at Grubby Games' IncrediBots. The latest beta build offers eight tutorial levels, nine challenges with multiple difficulty settings, and a sandbox mode which can be used to create robots of any size, shape and function to share with other users.

A simple registration process is required to save robots and replays created in sandbox mode, although this step is hassle-free and doesn't involve replying to email validation requests. (manual)
