Today a new great 3D level design that most of you should recognize, the GBA Circuito Mario.
Mario Circuit from Mario Kart: Super Circuit is part of the Flower Cup as the first race course. This Mario Circuit is a rather plain stage and short in length, with few obstacles and Item Boxes to deal against rivals. It contains winding paths, however, such as a hairpin bend, or a curl path found before the home stretch. Next to the checked line there is a detour where racers can get a speed boost by running onto a Dash Panel located there. It's also the first track titled "Mario Circuit" in the Mario Kart series, as Super Mario Kart had more than one Mario Circuit, while Mario Kart 64 had Mario Raceway.
