The games can be played alone, with other players who are with them using console controllers, or online with multiple players (who they may or may not know). Some Mario Kart games allow for in-game purchases, for items such as additional karts.
Although Mario Kart games don’t have in-game voice chat or messaging, players can communicate using dedicated apps such as Discord. Some games on the Nintendo Switch allow voice chat for players aged 13+ using the Nintendo Switch Online smartphone app.
Nintendo consoles (such as Nintendo Wii) provide parental controls for games such as Mario Kart and there is a Nintendo Switch Parental Controls app where parents can access additional parental controls features. In addition, ‘Nintendo Family Group’ enables parents to supervise their children’s Nintendo Accounts – this includes preventing purchases. Additional safety settings will be available on iOS and Android if these platforms are being used to play Mario Kart games.
