Mario Bros. Tour

The Mario Bros. Tour was the twelfth tour of Mario Kart Tour that began on February 26, 2020 and ended on March 10, 2020. It introduced a new Mario Circuit course, RMX Mario Circuit 1, as well as variants of Mario and Luigi in outfits based on their appearances and artwork for older games such as Donkey Kong (for Mario) and Super Mario Bros. 2, and similar to their appearances in the three DIC Mario cartoons. Additionally, for the first time, Mario, Luigi, and two Super karts called the Super 1 and Dasher II were made available as the first Super spotlight items. This is also the first tour to have only 50 pipe pulls in a pipe rather than the usual 100. The end date of the Mario Bros. Tour also marked Mario Day. The menu's background featured the hills and the block formation from World 1-1 as landmarks for this tour.

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.

Rewards
Gold cells indicate rewards exclusive to Gold Pass members.

Initial pipe appearance rates
During the Mario Bros. Tour, the amounts of the various items were changed. These pipes hold 50 items instead of 100, and feature Super Spotlights for the first time:
