Super Mario Bros.: The Lost Levels (originally Super Mario Bros. 2, also known as Super Mario Bros. 2: For Super Players) is a 1986 Japanese platform video game developed by Nintendo R&D4 and published by Nintendo. It is a sequel to Super Mario Bros. (1985) and was originally released in Japan for the Famicom Disk System as Super Mario Bros. 2 on June 3, 1986. Nintendo of America deemed it too difficult for its North American audience and instead released an alternative sequel, also titled Super Mario Bros. 2, in 1988. The game was renamed The Lost Levels and first released internationally in the 1993 Super Nintendo Entertainment System compilation Super Mario All-Stars. It was ported to the Game Boy Color, Game Boy Advance, Wii, Nintendo 3DS, Wii U and Nintendo Switch.
The game is similar to its predecessor in style and gameplay, with players controlling Mario or Luigi to rescue Princess Peach from Bowser. The Lost Levels adds a greater level of difficulty and Luigi controls slightly differently from Mario, with reduced ground friction and increased jump height. The Lost Levels also introduces obstacles such as poison mushroom power-ups, counterproductive level warps, and mid-air wind gusts. The game has 32 levels across eight worlds and 20 bonus levels.
Reviewers viewed Super Mario Bros.: The Lost Levels as an extension of the previous game, especially its difficulty progression. Journalists appreciated the game's challenge when spectating speedruns and recognized the game as a precursor to the franchise's Kaizo 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 Nintendo games.
