The controls are similar to the DS version of the game, with 2D side-scrolling gameplay, but the stage backgrounds are primarily 3D, making it a 2.5D game. Up to four players can appear on the screen simultaneously, either cooperating or competing with each other. The characters include Mario, Luigi, Yellow Toad, and Blue Toad. When a single player takes on the game, they can only choose Mario.

The game primarily uses the Wii Remote's D-pad to move Mario or other characters left and right. Pressing down will make the character crouch. Pressing up has no effect, but if you tilt the controller upwards, the character will spin jump. Holding the 1 button while moving causes the character to run, and performing three consecutive jumps during a run will execute a high bounce front flip. The 1 button can also be used for special actions such as grabbing enemies or throwing ice balls.

The gameplay introduces new mechanics like lifting and carrying, as well as throwing other players. Pressing the 2 button allows the character to jump, and holding it down results in a higher jump. In multiplayer mode, pressing the A button puts the character into a bubble, which can be useful for reaching normally inaccessible areas. When a player dies, they will reappear in a bubble, and other players need to pop the bubble to resume play.
