This is really good i like the mobile one because it's free I always find a way to get in first place im new so I only got a low place once in the game. in this Game you race with your karts you can also pick a Mario character the karts match with the character and to get characters you can buy them with your ruby's but i feel like once you play more the racing gets harder also once you finish the racing they give you more rounds. That's all my guiding sorry if I spoiled the game for you guys.
