Super Mario Bros.

Super Mario Bros.[b] is a platform game developed and published by Nintendo. The successor to the 1983 arcade game Mario Bros. and the first in the Super Mario series, it was released in 1985 for the Famicom in Japan. Following a limited US release for the Nintendo Entertainment System (NES), it was ported to international arcades for the Nintendo Vs. System in early 1986. The NES version received a wide release in North America that year and in PAL regions in 1987.

Players control Mario, or his brother Luigi in the multiplayer mode, as they travel the Mushroom Kingdom to rescue Princess Toadstool from Bowser (King Koopa). They traverse side-scrolling stages while avoiding hazards such as enemies and pits with the aid of power-ups such as the Super Mushroom, Fire Flower and Starman.

The game was designed by Shigeru Miyamoto and Takashi Tezuka as "a grand culmination" of the Famicom team's three years of game mechanics and programming, drawing from their experiences working on Devil World and the side-scrollers Excitebike and Kung Fu to advance their previous work on platforming "athletic games" such as Donkey Kong and Mario Bros. The design of the first level, World 1-1, serves as a tutorial for platform gameplay.

Super Mario Bros. is frequently cited as one of the greatest video games of all time, with praise for its precise controls. It is one of the best-selling games of all time, with more than 50 million copies sold worldwide. It is credited alongside the NES as one of the key factors in reviving the video game industry after the 1983 crash, and helped popularize the side-scrolling platform game genre. Koji Kondo's soundtrack is one of the earliest and most popular in video games, making music into a centerpiece of game design. The game began a multimedia franchise including a long-running game series, an animated television series and a feature film. It has been rereleased on most Nintendo systems. Mario and Super Mario Bros. have become prominent in popular culture.
