Professor Heinz Wolff's Gravity

Professor Heinz Wolff's Gravity is a puzzle game similar to the Incredible Machine series. During the 100 levels the goal is always to press a button. To achieve this goal the player has a selection of items to his disposal - nothing fancier than boards or balls - to build a construction of chain reactions. When he starts the experiment, a ball (in seldom cases a vehicle) gets released to set the thing in motion. An innovation compared to similar games is that the physics simulation doesn't get disabled during the building phase. This means the player can destroy his constructions when being careless during placing another item. There is also a help functions which gives hints to the correct solution.
