Mario Kart Tour

Mario Kart Tour is a mobile game in the Mario Kart series. Like Super Mario Run, it is free to download from the App Store and Google Play. The game reuses many assets from Mario Kart 7 and Mario Kart 8, as well as gameplay mechanics such as gliding, underwater driving, character-specific and unique items. In addition, the game introduces some new features to the Mario Kart franchise, such as reversed courses, trick courses, and the ability to deploy a large amount of any item during a race, including blue or red shells and bullet bills.
