The Nintendo Game & Watch Super Mario Bros — Mario’s Single Screen Adventure
The Nintendo Game & Watch Super Mario Bros, released in March 1988, brought Nintendo’s most iconic franchise to the Game & Watch format — featuring Mario running and jumping across a single screen in a side-scrolling platformer adaptation. Released three years after the original Super Mario Bros had transformed the NES into a global phenomenon, this Game & Watch version brought portable Mario gameplay to audiences who could not yet play the NES game on the move. The Super Mario Bros Game & Watch’s single-screen format distilled the essence of Mario’s running and jumping into a compact LCD experience, making it one of the most popular Game & Watch models and among the most desirable for collectors of both Mario memorabilia and Game & Watch hardware.
