Professor Heinz Wolff's Gravity is a fun and highly addictive puzzle game that you won't want to put down. The task is to simply build a track to get the ball rolling to its destination and ultimately hit the button to move you to the next level. But things aren't always as simple as they look, you will need to make full use of physics to build structures and help the ball or cart on its way. Party Mode is full of minigames like tallest tower. Build a tower before the earthquake arrives and see how your tower stands up against human nature or use the Sandbox Mode to make your own structures and designs.
