A truck carrying packages arrived at the post office in Pass It Up. Usually, to receive them, the gate on the ground floor opens, a car drives in, and several workers quickly unload all the boxes into the warehouse. But this time the gate did not work, so it was decided to unload the parcels on the top floor. To do this, one worker was placed on each floor. The one at the bottom must throw the box so that the one at the top will catch it. You will control the process by clicking on the box when you can throw it and not miss in Pass It Up.
