Super Mario Bros. (Game & Watch)
Super Mario Bros. is a Game & Watch version of Super Mario Bros. which appeared as part of the New Widescreen and Crystal Screen series, both of which were predated by an extremely rare "special" Game & Watch shaped like Famicon mascot Diskun which was awarded to winners of the F-1 Grand Prix Tournament in Japan.
These versions of Super Mario Bros. are all essentially the same except for hardware (the Crystal Screen had a transparent screen, while the other two versions were more basic Game & Watch systems). The overall plot is the same as the console Super Mario Bros., but the game is shorter and simpler.
Story from the instruction booklet
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 toss a hammer instead of tossing Spinies, and Bullet Bills will appear randomly. 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. Mario can also obtain 1-Up Mushrooms and Super Stars by hitting platforms, just like the NES version, at certain places during specific events within the game.
The Game and Watch has a 1-bit pallete (only black and white). Due to the low-powered CPU, the game does not feature Luigi, or multiplayer mode.
Holding Jump and pressing the Game button will start you on L3-1, with 90 distance and enemies enabled.
