3DS Rainbow Road

Rainbow Road is the last course of the Special Cup in Mario Kart 7. The course has once again increased in length compared to previous renditions, but still shares a similar theme to its predecessor. Instead of floating above the atmosphere, it now takes place around the Moon, with several small asteroids in the background. As a result, unlike past Rainbow Roads, this incarnation features the player driving on off-road surfaces such as the Moon itself and rings of. It is the first Rainbow Road course to contain one lap divided into three sections, being followed by in Mario Kart 8. Due to its length, it is the longest course in the Mario Kart series, and as such is also the longest Rainbow Road in the series; however, the Mario Kart 64 iteration of Rainbow Road takes more time to complete, as it is three laps long instead of one.

This Rainbow Road returns as a retro course in Mario Kart Tour, starting with the 2019 Holiday Tour. While not the only course divided into sections in the game due to the presence of N64 Kalimari Desert 2, Tokyo Blur 4, and New York Minute 4 or the only 3-lap (or in this course's case, 3-section) track in the game due to the existence of GCN Baby Park T, it is the only track to have both traits. It also returns in Mario Kart 8 Deluxe as the fourth and final course of the Moon Cup in the Booster Course Pass.

Mario Kart 7
Along with Wuhu Loop and Maka Wuhu, Rainbow Road only has one lap instead of three. It is divided into three sections to resemble laps, with banners at the end of each section. It is the only course in the game with three sections to not take place on Wuhu Island.

When performing a trick on this course, a slightly different sound effect will be produced when compared to other courses; the same applies to.

This course has the most Glide Ramps out of every Mario Kart course, with five. However, only the Glide Ramps going onto and off of the planet rings are mandatory.

Course layout
The race starts off with a short straightaway, following with a sharp turn to the right, then left, going around a planet. Afterward, there are three platforms that the drivers drive and jump off each one (similar to the area before the temple in DK Jungle). Next, players drive around another planet, but are spiraling down as they do so, with drop-offs allowing for tricks. The track then comes to a rainbow-spotted Mushroom Trampoline, and then a sharp right turn. After the turn, players have the opportunity to snatch some item boxes and coins on a waving road (similar to Mario Kart Wii).

Section two starts off with another sharp turn followed by a Glide Ramp, which activates the Glider to ride onto the rings of a Saturn-like planet. Players have to dodge holes in the rings before they then come to a section where they can hit some Dash Panels for speed boosts. Players then activate their Glider again after hitting the next Glide Ramp at the end of the rings. Once landing, players take three turns, all loaded with Dash Panels. Next, there is another wavy road, but this one has holes in it. Once the drivers make it through the wavy road or fall through, they land on the moon, where they need to dodge rolling Chomps, and they can trick off of craters for little boosts. Though there's no water in the moon portion, its low gravity works identically to the physics of driving underwater, so sometimes players can fly far with just one trick.

Section three starts with some conveyor belts that give little boosts, then leads into a turning tunnel with Dash Panels and Glide Ramps at the end. The track splits into two parts, then three, then two, before fusing back into one. This part is filled with ramps that can be used to go through rings for extra speed. If players hit a Glide Ramp, they have to dodge asteroids, but try to pass through rings at the same time. The track ends with a part that increases in altitude, then decreases again, leading to one small jump facing the finish line.

When the player crosses the checkpoint to begin the next section, Lakitu is shown on the left side of the player, holding the section count signs.

There are three Item Boxes floating under the rings of the Saturn-like planetoid. It is possible to get one of these Item Boxes by gliding, but the player must get back on the track after getting it in order to use their item. However, it is quite difficult to do so without a mushroom.

Shortcuts

 * The first turn of the second section can be skipped or taken tightly by drifting off the red and white striped side of the road.
 * Time can be gained by repeatedly swooping far down below the planetoid’s ring and up again after the first Glider ramp.
 * Another Glider shortcut can be performed with the second Glider ramp by gliding off to the left back over the planet’s ring and landing after or on the second set of Dash Panels, skipping the turn.
 * The last turn of the course can be skipped by drifting off the red and white striped side of the road and landing on the final straightaway.

Staff ghost
The staff ghost is Honey Queen with the Birthday Girl, Slim tires, and Peach Parasol, and the expert staff ghost is Honey Queen with the Bumble V, Standard tires, and Flower Glider.

Mario Kart Tour
This version of Rainbow Road returns in Mario Kart Tour, starting with the 2019 Holiday Tour, alongside New York Minute 2. Various changes have been made to the track - it is noticeably flatter overall, with several turns being far less banked. The series of jumps following the first few turns have been aligned. The rails on the race track are now formed by golden stars while the rails on the moon are now formed by cyan neon lights. The star-shaped arches now have disco balls at the edges like the star on the spinning tunnel in the final section. The series of turns following the second Glide Ramp have also been made tamer. The start-and-finish truss now resembles a rainbow arch with a half star surrounding it and displays the Mario Kart logo in cyan, Toads in space suits now appear as spectators next to the spaceships, and the moon near the first turn is now a blue planet (, to be precise), while replaces the second moon. After the start of the third section, the golden arches are replaced with star-shaped arches. The launch rings are now cyan, resembling the launch ring items. Earth is also now visible in the background of the track, and the galaxy has been replaced by the. This course is a favorite of Lemmy, Birdo (Light Blue), Mario (Happi), Rosalina (Aurora), Daisy (Fairy), Fire Rosalina, King Boo (Gold), King Bob-omb (Gold), Birdo (White), and the Rosalina and Gold Mii Racing Suits. This course is also a favorite of Mario (Satellaview) and Rosalina (Swimwear) if they are at level 3, Baby Peach if she is at level 6, and Dry Bowser (Gold) if he is at level 8. Like all other courses, Rainbow Road has a reverse variant referred to as Rainbow Road R, a trick variant known as Rainbow Road T, and a reverse and trick variant known as Rainbow Road R/T, which debuted in the Baby Rosalina Tour.

The T and R/T variants of this track are two of four courses in Mario Kart Tour that do not start in the same place as the original, the other ones being 3DS Rock Rock Mountain T and Singapore Speedway R/T. For both variants, the starting line is now just after the spinning tunnel.

Mario Kart 8 Deluxe
This version of Rainbow Road returns as the fourth and last course of the Moon Cup in the Booster Course Pass DLC for Mario Kart 8 Deluxe. It is based on its appearance in Mario Kart Tour, albeit with a graphical overhaul, giving the course a neon aesthetic. The Dash Panels on the Saturn-like planet’s rings now have boost rings on top of them. The boost rings and the star-shaped rails on the track now resemble the ones used. Some of the star gates the player drives through are now silver instead of gold. The rainbow arch on the start-and-finish truss is now a complete circle. The planets throughout the course further resemble real life planets, such as and  (with the former replacing ). The moon section is now in anti-gravity, just like the battle course Lunar Colony.

Excluding Mario Kart 8's Rainbow Road theme, which is used in all trailers for the Booster Course Pass, was one of two courses whose music was used for the second trailer for Wave 3, alongside.

Other appearances
This Rainbow Road appears in Super Smash Bros. for Nintendo 3DS as a stage. The match takes place on flat platform and is a cruise-type stage similar to Port Town Aero Dive. Shy Guys also appear as stage hazards similar to the F-Zero machines from Port Town Aero Dive and the Shy Guys from Figure-8 Circuit. It also has a trophy in this game.

Music
Like in Mario Kart: Double Dash!!, the music for the course contains an arrangement of Mario Kart 64 ' s Rainbow Road's music. (Kenta Nagata was a composer for all three games.) There are two different variations of this theme. The first variation plays while driving on the rainbow tiles, and the second variation plays during the second section when the player is driving on the moon. When the third section is reached, the end of the music, which is the arrangement of the end of Mario Kart 64 ' s Rainbow Road, plays first, instead of the start of the music. In Mario Kart 7, if the player turns around and goes back to the moon section after crossing the entrance to the third section, the music will change to the final lap version of the second variation of the theme, but only if the player enters it after hearing the final lap theme after moving onto the third section. The player will not hear the final lap version of the second variation of the theme if they reenter the moon before hearing the final lap version of the original variation, even if they already moved on to the third section. It is possible to hear the final lap version of the second variant in Mario Kart Tour during the Trick variant, since the moon is in the final segment in this version of the track.

This course's music also appears in the Super Smash Bros. series as selectable music tracks, both in its original arrangement and as a part of "Rainbow Road Medley". Both are playable on the Rainbow Road stage in Super Smash Bros. for Nintendo 3DS, the Mario Circuit stage in Super Smash Bros. for Wii U, and any Mario Kart stage in Super Smash Bros. Ultimate.
