Players control a physical remote-controlled kart that has a built-in camera, which streams a live feed to their Nintendo Switch console. The game creates a virtual racecourse on the player's floor and allows them to drive their kart around obstacles and compete against other players on-screen. Players can customize their karts with various designs and race in different modes, such as Grand Prix and Time Trials. Mario Kart Live: Home Circuit provides a unique and immersive gaming experience that combines physical play with digital technology.
