Super Mario Bros. is a platform game developed and published in 1985 by Nintendo for the Famicom in Japan and for the Nintendo Entertainment System (NES) in North America. It is the successor to the 1983 arcade game Mario Bros. and the first game in the Super Mario series. Following a US test market release for the NES, it was converted to international arcades on 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.

A platformer is a sub-genre of action video games in which the core objective is to move the player character between points in an environment. Platform games are characterized by levels with uneven terrain and suspended platforms of varying height that require jumping and climbing to traverse. Other acrobatic maneuvers may factor into the gameplay, such as swinging from vines or grappling hooks, jumping off walls, gliding through the air, or bouncing from springboards or trampolines.
