The game consists of creating your own levels and playing premade and online stages with graphics and features across four Mario games: Super Mario Bros., Super Mario Bros. 3, Super Mario World and New Super Mario Bros. U. You can place objects like "?" blocks that contain items and power-ups, pipes, blocks of different colors and styles, flamethrowers, spikes, switches and enemies like Goombas, Koopas, Buzzy Beetles, Spinies, Cheep Cheeps, Thwomps, Boos, Bowser, etc. (although some are exclusive to certain versions).
The game also features the 100 Mario challenge, which has three levels of difficulty and brings you levels that most of the community hasn't completed. It also includes ten pre-made courses to play, as well as MiiVerse features and amiibo compatibility so you can scan figures and use them in the game.
