Mario Kart Tour is a mobile game in the Mario Kart series. Unlike Super Mario Run, it is free-to-play from the App Store and Google Play. The game reuses many assets from Mario Kart 7 and Mario Kart 8, though its art style is more simple and cartoony. Gameplay mechanics such as gliding, underwater driving, and character-specific special items return from past entries. In addition, the game introduces some features new to the Mario Kart series, such as reverse courses, trick courses, a combo system that grants points based on actions, and the Frenzy mechanic, which allows racers with three item slots to deploy a large amount of any item during a race, including Spiny Shells and Bullet Bills, at random should said item be in all three slots.
