Hammer Bro Tour

The Hammer Bro Tour is the fourteenth tour of Mario Kart Tour that began on March 25, 2020 and will end on April 7, 2020. It is the second tour to be named directly after a character. The featured course of the tour is Donut Plains 1 from Super Mario Kart, while also bringing back Bowser's Castle 2 from Mario Kart: Super Circuit, making it the first tour to introduce a new Retro Course since the Ice Tour. Hence the name, the tour marks the playable debut of Hammer Bro (who was originally going to be playable in Mario Kart Wii), Boomerang Bro, Ice Bro, and Fire Bro, in which they also act as the spotlight characters for the tour. Additionally, unlike the previous two tours, each week's respective pipes go back to having 100 items in the pipe instead of 50.

Signature kart sets
In every cup, the driver which the cup is themed about is raised a tier on each track, making them a three- or two-item driver on that course. Up until the Ice Tour, a kart and a glider were also given a bonus for each race in the cup.
