Event token

Event tokens are special green coins that appear during certain events in Mario Kart Tour, starting with the Wild West Tour. During the second week of the Wild West Tour and the Super Mario Kart Tour, event tokens appeared in all courses in a tour, where they replace several of the normal coins in a random manner. They could also be obtained from Item Boxes instead of normal coins, from other drivers who have gotten hit, and from the Coin Box special item. During the second week of the Pirate Tour, they could be earned from landing hits with shells. During the second week of the Summer Festival Tour, they could be earned from landing hits with Bob-ombs.

Event tokens can then be used to purchase items from an Event Shop, which contains items not found in the Daily Selects, such as points-cap tickets and rubies. All items have a limit for how many times they can be purchased. Players can only have as many event tokens as needed to purchase all of the items in the Event Shop, after which they will stop appearing on courses. Any unspent event tokens collected in one tour are not carried over to the next.

Event tokens are very similar in appearance to the Bonus Medals in Super Mario Run, having a similar Super Star design on them.
