Rainbow Road (Mario Kart 8)

Rainbow Road is the fourth and final course of the Special Cup in Mario Kart 8. Like Rainbow Roads in previous Mario Kart titles, this Rainbow Road takes place in space, along with Mario Kart TV satellites and space stations. In the background lies the Earth, similar to that of Rainbow Road from Mario Kart Wii. One noticeable feature of the track is a space shuttle that resembles a Blooper, that circles around the track, similar to how the train circles around the Lightning Cup's N64 Rainbow Road. The track, similar to Rainbow Road in Super Mario Kart, is made of color square tiles that change colors like the Rainbow Roads from Mario Kart Wii and Mario Kart 7. Mario Kart 8's producer, Hideki Konno, describes it as "spectacular".

Course layout
The course start with the rainbow-colored tiles. After a turn the drivers find the first anti-gravity section, that is 8-shaped. A gliding pad is found after the anti-gravity section and leads to a space station. It contains conveyor belts with opposite directions that changes over time, like Toad's Factory from Mario Kart Wii. At the end of the belts there are alternate Boosts (that turn on and off through time) and two gliding pads that leads to two different anti-gravity paths. These paths alter in height, so if the player falls from the highest one, they can simply land on the other one. The player can see a Blooper-like spaceship orbiting around. Then the paths reunite each other and the antigravity section ends. A 180° turn with some Boosts Pad at the outermost part, like in Mario Kart Stadium from Mario Kart 8, and another turn make the track loop end. The racers then start the next lap.

Trivia

 * This Rainbow Road as well as its Retro Cup counterpart are the only courses in Mario Kart 8 with different colored maps on the GamePad than the others, being rainbow-colored instead of the standard blue.
 * At the final 180° turn the player can see a hologram projection of the Special Trophy as it appears in Mario Kart 8.
