Super Mario Bros. is a Game & Watch game released as a part of the Crystal Screen series on June 25, 1986, and as a part of the New Wide Screen series on March 8, 1988. It was the first game in the Crystal Screen series. It is a single-screen single-player Game & Watch.
It was also made available as a prize for winners of the Famicon's F-1 Grand Prix tournament on August 1, 1987 with code YM-901-S. It is a single-screen single-player Game & Watch with a yellow case. It came in a plastic box modeled after Disk-kun, the character Nintendo used to advertise the Famicom Disk System. This edition is the rarest of all Game & Watch models, as only 10,000 units of this version were produced and it was never available for retail sale.
Mario has to go through levels to save Princess Toadstool (also known as Peach) similar to the NES game.
Super Mario Bros. was rereleased as part of the Nintendo Mini Classics 1998 in Game & Watch Gallery 3 for Game Boy Color in 1999.
