Super Mario Bros. (Game & Watch)
Super Mario Bros. is a Game & Watch version of Super Mario Bros. that appeared as part of the New Wide Screen and Crystal Screen series. Both of them were predated by an extremely rare "special" Game & Watch shaped like Famicom mascot Diskun, which was awarded to winners of the F-1 Grand Prix Tournament in Japan. The Crystal Screen version had a transparent screen, while the other two versions were more basic Game & Watch systems.
These versions of Super Mario Bros. are all essentially the same in terms of presentation; the overall plot is the same as the console Super Mario Bros., but the game is shorter and simpler. It is one of the few Game & Watch games that does not have a Game B.
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 is 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 in the NES version, at certain places during specific events within the game.
The Game & Watch has a 1-bit palette (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 Mario on L3-1, with 90 distance and enemies enabled.
