Mario Circuit (Mario Kart 8)

The Mario Kart 8 incarnation of Mario Circuit appears as the first course of the Flower Cup. This Mario Circuit's layout is designed after the Möbius strip (a closed surface consisting of only one side) to make full use of the new anti gravity aspect of the game. It is placed around Peach's Castle which happens to be on floating islands. Like Figure-8 Circuit, the track is shaped like an 8. There are Goomba Towers near the finish line that can slow down the player. This track uses both the Hang Glider from Mario Kart 7 and also the new anti-gravity wheels in Mario Kart 8. The track is lush and green, surrounded by the blue sky and white clouds. Mario Kart Stadium's theme is a cover of this track's music.

The track appears in Super Smash Bros. for Wii U as a new stage. The stage has been shown to take place on several platforms that move around the stage, stopping at certain intervals around the stage similar to Rainbow Road in the 3DS version. Shy Guys can drive into the fight like in the aforementioned stage and the other Mario Circuit stage, however because of the anti-gravity element they can drive on other surfaces such as on the wall to the right of the players or from the background albeit upside-down. Three musical tracks have been confirmed for the stage so far: Mushroom Gorge from Mario Kart Wii, Rainbow Road from Mario Kart 7, and the "Pandemonium" minigame music from Mario Party 9.

Course layout
Being designed after a Möbius strip, the track follows a single path that twists around near the beginning. The track remains fairly simple in terms of design. Players start on the straightaway of the Möbius strip and shortly after, there is a turn to the left. A white bridge is a short ways away of the turn which starts the anti gravity section. The track turns to the right shortly after and start racing underneath the finish line. After a left turn, the racers cross the white bridge, which twists the track back to normal and after another right turn, the racers approach the finish line. A gliding ramp and Goomba Towers appear at the stretch to the finish.

Trivia

 * This is one of the three courses in Mario Kart 8 to be playable in the E3 2013 demo, the other two being Toad Harbor and Twisted Mansion.
 * On a side note, all three take place in the Flower Cup, and are in the same order as they were in the demo.
