Is Mario Kart Tour a cross-platform game?

Mario Kart Tour is not a cross-platform game as it is exclusively designed for mobile devices, specifically iOS and Android platforms. Unlike some other games in the Mario Kart series that can be played across different consoles or systems, Mario Kart Tour focuses on providing a Mario Kart experience tailored for play on smartphones and tablets, utilizing a touchscreen interface and mobile-centric gameplay features. This means that players on different types of devices, like a Nintendo Switch or a PC, cannot play alongside those using the mobile app version of Mario Kart Tour.
