Mario Kart Tour’s gacha elements are getting removed, according to a tweet by the game’s official account. Starting in late September, all pipes that can be fired by rubies will receive the axe and will no longer be available.
Pipes are packages players can “fire” in order to receive karts, drivers, and other items. It’s essentially like a “pull,” and what comes out of each pipe fired is unknown. Players could earn rubies in-game or through spending real legal tender.
Now with the change, items like drivers, carts, and gliders will be located in a separate shop where players can exchange rubies towards a specific item they desire–instead of relying on luck and quantity as in the the previous gacha system
