In this version of the game, you have to build a mobile able to reach the pink zone, by joining colored wheels with the connectors. There's 3 types of wheels: the brown turn in one sense, the light blue in the other, and the grey ones simply react to external impulses. There's 3 types of connectors: water connectors can cross other objects, wood ones collide, bounce or push others, but never cross them, and the solar panels enable you to save and even stock energy. The game includes a very detailed tutorial that will guide you step by step.
Click on the tool you want to use, then click at the points where you want to use it. For example, click on the pink wheel tool and then click at a point to place it there. Or click at the water connector and then click at the two sides you want to connect (usually, a point over a wheel and other point over another wheel). The game includes a detailed and easy to learn tuturial that will guide you step by step.
