Super Mario Bros. 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) in late 1985, the Vs. Super Mario Bros. arcade game port for the Nintendo Vs. System received a wide international release for overseas markets outside of Japan in early 1986, before the NES version received a wide release in North America the same 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 must 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 first-time video gamers on the basic mechanics of platform gameplay. The aggressively size-optimized profile was intended as a farewell to the Famicom's cartridge medium in favor of the forthcoming Famicom Disk System, whose floppy disks temporarily became the dominant distribution medium for a few years.

Super Mario Bros. is frequently cited as one of the greatest video games of all time, with praise on 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. Alongside Mario himself, Super Mario Bros. has become prominent in popular culture.

SUPER MARIO BROS: THE LOST LEVELS

Super Mario Bros.: The Lost Levels is a 1986 side-scrolling platform game developed and published by Nintendo as the first sequel to their 1985 bestseller Super Mario Bros. The games are similar in style and gameplay, apart from a steep increase in difficulty. Like the original, Mario or Luigi venture to rescue the Princess from Bowser. Unlike the original, the game has no two-player option and Luigi is differentiated from his twin plumber brother with reduced ground friction and increased jump height. The Lost Levels also introduces setbacks such as poison mushroom power-ups, counterproductive level warps, and mid-air wind gusts. The game has 32 levels across eight worlds as well as 20 bonus levels.

The Lost Levels was first released in Japan for the Famicom Disk System as Super Mario Bros. 2 on June 3, 1986, following the success of its predecessor. It was developed by Nintendo R&D4—the team led by Mario creator Shigeru Miyamoto—and designed for players who had mastered the original. Nintendo of America deemed the title too difficult for its North American audience and instead chose another game as the region's Super Mario Bros. 2: a retrofitted version of the Japanese Doki Doki Panic. North America first experienced The Lost Levels, as the Japanese sequel became known, in the 1993 Super Nintendo Entertainment System compilation Super Mario All-Stars. It was later ported to the Game Boy Color, Game Boy Advance, Virtual Console (Wii, Nintendo 3DS, and Wii U), and Nintendo Switch.

The title is known for its intense difficulty, which contributes to its reputation as a black sheep in the franchise. Reviewers viewed The Lost Levels as an extension of the original release, especially its difficulty progression. Journalists appreciated the game's challenge when spectating speedruns, and recognized the game as a precursor to the franchise's subculture in which fans create and share ROM hacks featuring nearly impossible levels. This sequel gave Luigi his first character traits and introduced the poison mushroom item, which has since been used throughout the Mario franchise. The Lost Levels was the most popular game on the Disk System, for which it sold about 2.5 million copies. It is remembered among the most difficult games by Nintendo and in the video game medium.

SUPER MARIO BROS 2

Super Mario Bros. 2 is a platform video game developed and published by Nintendo for the Nintendo Entertainment System. The game was first released in North America in October 1988, and in the PAL region the following year. It has been remade or re-released for several video game consoles.

The western release of Super Mario Bros. 2 was based on Yume Kōjō: Doki Doki Panic, a Family Computer Disk System game meant to tie-in with Fuji Television's media technology expo, called Yume Kōjō (lit. Dream Factory). The characters, enemies, and themes of the game were meant to reflect the mascots and theme of the festival. After Nintendo of America found the Japanese version of Super Mario Bros. 2 (later released internationally as Super Mario Bros.: The Lost Levels) to be too difficult and similar to its predecessor, Yume Kōjō: Doki Doki Panic was modified to become Super Mario Bros. 2 for release outside of Japan.

A commercial success, the international Super Mario Bros. 2 was re-released in Japan for the Famicom as Super Mario USA (1992), as part of the Super Mario All-Stars (1993) collection for the Super NES (including the Japanese Super Mario Bros. 2 as The Lost Levels), and as Super Mario Advance (2001) for the Game Boy Advance.

SUPER MARIO BROS 3

Super Mario Bros. 3 is a platform game developed and published by Nintendo for the Nintendo Entertainment System (NES). It was released for home consoles in Japan on October 23, 1988, in North America on February 12, 1990 and in Europe on August 29, 1991. Prior to its release on the NES, it was initially released in North America on July 15, 1989 via PlayChoice-10 arcade machines. It was developed by Nintendo Entertainment Analysis and Development, led by Shigeru Miyamoto and Takashi Tezuka.

Players control brothers Mario or Luigi, who must save Princess Toadstool and the rulers of seven different kingdoms from the antagonist Bowser. As in previous Mario games, they defeat enemies by stomping on them or using items that bestow magical powers; they also have new abilities, including flight and sliding down slopes. Super Mario Bros. 3 introduces many elements that became Mario franchise staples, such as Bowser's children (the Koopalings) and a world map to transition between levels.

Super Mario Bros. 3 was praised by critics for its challenging gameplay and is listed as one of the greatest video games of all time. It is the third-best-selling NES game, with more than 17 million copies sold worldwide. It also inspired a short-lived animated television series produced by DiC Entertainment called The Adventures of Super Mario Bros. 3.

Super Mario Bros. 3 was remade for the Super NES as a part of Super Mario All-Stars in 1993 and for the Game Boy Advance as Super Mario Advance 4: Super Mario Bros. 3 in 2003. It was rereleased on the Virtual Console service on the Wii U and 3DS, and was included on the NES Classic Mini. On September 19, 2018, it was rereleased on the Nintendo Switch Online service with added netplay.
