Mario must go through eight auto-scrolling levels without falling and losing a life. When the levels are cleared, Mario must repeat them in the next loop. The second loops and onward have enemies. Further, Lakitus throw hammers as opposed to Spinies. There are a total of nine loops of increasing difficulty. There are two types of levels; scroll screen levels and timer screen levels. In the scroll screen levels, Mario must travel a given distance displayed on the screen. In the timer screen levels, Mario has to go through the world within a given time.
