How to Play Professor Heinz Wolff's Gravity
Quick start
Open an available early puzzle and identify its starting point and target switch. Tap the play area to bring up the available pieces, then drag one into position. Keep the stylus held while adjusting its angle; release only when it has support. Use the displayed start control to test, observe the first break in the chain and revise that part before testing again.
Controls
Tap the touch screen to open the object selection, then drag a piece into place. While holding it, use the D-pad to rotate; L/R align it vertically or horizontally. Releasing the stylus lets gravity act on the piece. X undoes the last move and Y redoes it. Use the on-screen test/start control to run the reaction.
Professor Heinz Wolff's Gravity — About this game
Professor Heinz Wolff’s Gravity asks you to turn a limited set of objects into a working chain reaction. The aim is to transfer motion towards a switch, using pieces as bridges, supports, falling weights or rolling links. Placement is part of the puzzle: an object starts obeying gravity when you release it, so a poorly balanced support can collapse before the main test begins. The DS combines stylus movement with button-controlled rotation and undo. Watch where a test stops, change one useful part and try again instead of scattering every piece at once. A successful arrangement may differ from the obvious route, leaving room to experiment with the same small collection of objects.
