Halloween Tour (2021)

The Halloween Tour was the fifty-fifth tour of Mario Kart Tour, which began on October 20, 2021 and ended on November 2, 2021. It was the eighth tour to have the same title as a previous tour, and the first instance of three tours sharing the same name. First announced at the start of the Autumn Tour, the tour introduced a new vampire-themed variant of Waluigi, as well as a new third variation of the London Loop course, named London Loop 3. This tour was also the second tour in a row and the third tour overall to include Jack-o'-lanterns scattered across courses. Rosalina (Halloween) and Mario (Halloween) (who both appeared as the week 1 spotlight drivers in the previous Halloween Tours) reappeared as spotlights for the second week.

This tour continued the Autumn Celebration that started in the previous tour, the Autumn Tour. Like that tour, it introduced new unique challenges, as well as an upgraded Token Shop, which included the Poison Apple Kart and Swooper. Like the 2021 Yoshi Tour, players were able to obtain Blue Yoshi as a reward for placing high in the tour's ranked cups.

This tour's Coin Rush course was 3DS Rosalina's Ice World, which was reused from the Rosalina Tour. The menu's background featured the Big Ben and some buildings from the London Loop courses as the landmark of this tour, which was reused from the London Tour and the Baby Rosalina Tour.

A seventh set of Expert Challenges was made available at the start of this tour, which then ended in the New Year's 2022 Tour, making this tour the first one since the Summer Festival Tour to not introduce an Expert Challenges card alongside a Team Rally, though a Team Rally would take place in the following tour.

Today's Challenge
Players' most recently used kart and glider are chosen, and favourite and favored ones have extra priority. Opponents are arranged randomly. On day 1 of this tour, players finish a race in 3DS Shy Guy Bazaar T in the Waluigi Cup using Dry Bones for a free pipe launch. Starting from day 2, players have to finish a race in the earliest incomplete course that is not in any of the ranked cups using the driver shown on the course's thumbnail every day to obtain the corresponding reward in the table below. Once all of the courses are completed, the courses are selected at random.

Rewards
Gold cells indicate rewards that are exclusive to Gold Pass members.

Token Shop
The limited-time event where event tokens appeared began on October 19, 2021, and ended on November 2, 2021. Event tokens could be collected from the course and Item Boxes in place of randomly selected normal coins. Event tokens could also be collected by running into Jack-o-lanterns or hitting them with items.

Tier Shop
The shop featured a variety of set and randomized items available for purchase. The item slots in the shop are unlocked based on the highest tier of players.
