This page is rather stubbly and could use some expansion. Are you a bad enough dude to rescue this article? Notes: The flash images should be analysed more. Graphics are stored in a simple format, and the ROMs seem to be auto-patched with values from the internal flash.

Game & Watch: Super Mario Bros. is a special Game & Watch unit made to celebrate the 35th Anniversary of Super Mario Bros., containing said game, The Lost Levels, and a Mario-themed version of Ball (a concept Nintendo had already done in G&W form as Mario the Juggler, itself notable for being the last game of the original G&W series).

Much to everyone's (dull) surprise, it was only available through March 31, 2021, though at least this one having a limited run is more understandable than the other two Mario games released around the same time.
