Gears and Chains: Spin It is a puzzle game that requires you to put gears into motion by connecting them with chains. You can only connect two gears with a single chain, and only gears of the same color can be connected. Also, chains can't intersect platforms that are the same color. A level is complete when all gears are moving. If you're having trouble with a level, you can skip it, but keep in mind that you have a limited number of level skips.
