Game in which individual, scattered boxes are pushed onto the designated parking spaces. The 'warehouse' in which the crates are stored has three floors, which are connected by elevators. The boxes can be transported by elevators to the desired floors. Once all the crates are in one place, the level is finished and a new one is loaded. With a special pusher you can also use the elevator without crates. On disk J 136 there is a special level editor, which can be used to create, change or test levels for Slider.
