Complete all 30 challenging levels that Truck Loader 3 provides. In each level there's a truck waiting for you to load it with one or more different crates. Use your magnetic arm to carry the crates and stack them in the back of the truck. In some levels you will have to use the crate to push the coloured button that offers you the passage to the next platform you need to get closer to the truck. Be careful how you carry the crates and how much time you waste on loading the trucks, there's minus points if you fail!
