Mario Kart is one of Nintendo's most successful franchises to date. Mario Kart Tour was initially announced early 2018 and was originally scheduled for release this spring. Since then, the game has had a closed beta and a delayed "summer 2019" release was revealed. Finally, just last night, Nintendo has officially announced via Twitter that Mario Kart Tour is arriving to iOS and Android on September 25. Buckle up, because #MarioKartTour will be available on 9/25. Follow @mariokarttourEN for more information heading into the game's release. pic.twitter.com/1V0njTVWRx— Nintendo of America...
