Big Reverse Race vs. 100

Big Reverse Race vs. 100 is a type of bonus challenge in Mario Kart Tour. It was added to the game's 2.14.0 update and was first released at the start of the 2023 Winter Tour. It is a version of the regular Big Reverse Race challenge, where the goal is similar to end the race in 1st place, but takes a slightly different approach. Players will start in 100th place and the objective is to aim for 1st place within a time limit using a set driver, kart, and glider, unlike the regular Big Reverse Race where players get to choose their setups. When the player gains 10 spots ahead, the 30 second timer resets and the player is able to continue further. The amount of Grand Stars earned upon completing a Big Reverse Race vs. 100 bonus challenge is also determined by the places they either pass or end up in: one star for 80th place or higher, two for 40th place or higher, and three for 1st place.
