Super Mario 3D World is a 3D platform game developed and published by Nintendo for the Wii U console in 2013. The game features Mario and his friends, such as Luigi, Princess Peach, and Toad, as they journey through various levels and worlds to rescue the Sprixies, a group of fairy-like creatures.

One of the main gameplay mechanics of Super Mario 3D World is the ability for players to switch between characters with unique abilities. For example, Luigi can jump higher than the other characters, Princess Peach can hover briefly in mid-air, and Toad is the fastest runner.

The game also introduces new power-ups, such as the Cat Suit, which allows characters to climb walls and scratch enemies, and the Double Cherry, which creates a clone of the character that can be controlled independently.

Super Mario 3D World was well-received by critics and fans, and it was later ported to the Nintendo Switch in 2021 as Super Mario 3D World + Bowser's Fury, which includes new content and features.
