Your goal in this online physics game is to build, guide, jump, and do all sorts of wonderful things with your very own robots, spawned from the depths of your creativity, in a wide-open, physics-based playground. You start with introductory levels which will teach you the game basics. Later, for a real test of your skill, you can try one of the Challenges from the main menu. Or you can try Sandbox mode, where you can make any robot or contraption you want. Have fun!
