Chain Reaction is a 3D variation of The Incredible Machine. You solve puzzles by arranging an assortment of levers, belts, motors and other items to achieve a goal. The game comes with timed levels and a sandbox mode. You can fully rotate the camera to observe your constructions and there are 8 settings for more than 50 game levels, along with a few tutorials.
The goal is to move a fuzzy monster to a designated spot in the level, using items such as flashlights, basketballs, trampolines and fans. The game depends on gravity as the primary key to all puzzles. The solutions require a pre-selected array of pieces to be arranged in certain ways. The game comes with a "Builder", a construction set where you can design your own levels with over 65 parts in the toybox. These can be exported and shared online.
