RMX Mario Circuit 1

RMX Mario Circuit 1 is a race track in Mario Kart Tour. It is a remix version of the Mario Circuit courses from Super Mario Kart that debuted in the Mario Bros. Tour and serves as its signature course. The course also appears as RMX Mario Circuit 1R (reverse variant) and RMX Mario Circuit 1T (trick variant; known as RMX Mario Circuit 1X on the main menu and favored courses lists, although this is likely a translation error as trick courses are labeled "X" in some languages).

Layout
The course uses the same aesthetics as the Mario Circuit courses from Super Mario Kart, but a completely different layout. Lots of Empty Blocks, ? Blocks, Goombas, and Piranha Plants appear in the course.
