If so, Super Mario Run costs £9.99 to unlock the rest of the game after the first demo world, so you could expect a similar outlay. We don't yet know whether that will require a major purchase to unlock the game beyond a few beginning tracks. Nintendo describes the new game as 'free-to-start', but there will be plenty of in-game purchases. One aspect of another Nintendo mobile game, Super Mario Run, that has been heavily criticised is its business model, but we expect Nintendo to follow a similar pattern with Mario Kart Tour. You can pre-register for each version on the respective app stores, with the iOS version available for pre-order here and Android version here. Mario Kart Tour will be available for iOS and Android. Plus, there will be special in-game events during different time periods. Other features of play will include different, collectable drivers, karts and gliders. Locations in the game will include Mario Kart classics, such as Rainbow Road, but also tracks based in major worldwide cities, including Paris, Tokyo and New York.
