Super Mario 3D World is a 2013 platform game developed and published by Nintendo for the Wii U. It is the sixth original 3D platform game in the Super Mario series and the sequel to Super Mario 3D Land (2011) for the Nintendo 3DS.

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.
