Connect cables from batteries to motors, build bridges, set up teeter totters, swing with ropes, build vehicles, or just let the marble have a happy roller coaster ride to the goal! Use the hammer or the wrench to connect planks, wheels and other objects together. Use the control panel to control your creations, be it a monster truck, a mechanical rifle or anything YOU can imagine! A minimum processor speed of 600MHz is recommended. A screen resolution of 800x480 or higher is recommended but the game runs on lower resolutions.
