Super Mario Bros.: The Lost Levels (originally Super Mario Bros. 2, also known as Super Mario Bros. 2: For Super Players) is a platform game and a sequel to Super Mario Bros. (1985). The Lost Levels is similar to its predecessor in style and gameplay, with players controlling Mario or Luigi to rescue Princess Peach from Bowser. The game 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.
