A warehouse worker is trying to place boxes. The cranes deliver boxes to the warehouse. They must be moved and formed rows. The boxes should be moved in a way that creates horizontal lines. You will get points if the lines disappear. The game will be over if the boxes reach the top of the screen. Do you want to move the boxes fast or consider your steps? There will be more cranes with every new level. The game will please all the fans of the 90's games.
