|Super Mario 3D World 2|
The game mostly plays out in a similar style to its predecessor, Super Mario 3D World, and partially, to an extent, Super Mario Galaxy. The player finishes a level by finding a Star Card, of which there are three per level; like Galaxy, there are different missions to earn these Star Cards. After completing the last mission in a castle stage, the player will instead earn a Grand Star Card, allowing them to progress to the next world. Like the first game, the player also needs to collect Green Stars to progress through the game, too. There is one Captain Toad level per world. These have the same mechanics as in the first game. A new type of level is added to this game, called Yoshi levels. As such, they play out as a 3D version of Yoshi's Island games although Yoshi is carrying a "Baby Toad" instead. There are three Yoshi levels per world, and at least one must be completed to access the boss level of a world.

When a block contains a Power-Up that Mario already has, it will turn into a Card. These Cards can be used as the inventory in previous games, but upon collecting three Cards of the same type, they can give Mario an upgraded version of the Power-Up. Upon collecting three upgraded Cards of the same type, they will become a Super Card, giving Mario another upgraded ability.
- Yoshi levels were added in to the game as a reference to this being the sequel to Super Mario 3D World; Super Mario World 2: Yoshi's Island is the sequel to Super Mario World.
- After completing a level, the loading screen will show every player's character as a 2D sprite in Super Mario Bros. These characters will then jump onto the top of the goal pole. The level being depicted is likely 1-1.
