Rainbow Road

Rainbow Road is the name of the last racecourse of the Special Cup in each of the Mario Kart games. These tracks are suspended in the starry night sky in outer space. Most contain few or no rails, putting racers at risk of falling, and each Rainbow Road also contains its unique hazards. Due to these obstacles, Rainbow Road is one of the hardest tracks in each Mario Kart game. Rainbow Road is also usually a long track when compared to other tracks.

''Super Mario Kart
This Rainbow Road lacks rails entirely and contains 90-degree turns. Rainbow-colored tiles cover the track's surface, and the yellow tiles conceal Coins and jumping humps. This course features Star Thwomps which can, unlike regular Thwomps, wipe out a racer by touch as well as by crushing, unless the racer activates a Star or a Boo, but they cannot be defeated by a Star. If any players use a Mushroom or star, they can jump over the gap near the end of the course. This is the only track in Super Mario Kart that is not numbered compared to the others. The track reappears in Mario Kart: Super Circuit, but it does not have the Star Thwomps.

Super Mario Kart composer Soyo Oka considers this course's theme one of her favorite compositions.

Rainbow Road makes its third appearance as the last course of the Lightning Cup in Mario Kart 7, being the first Rainbow Road to reappear as a retro track in another Mario Kart (not including when it, along with all other SNES tracks, appeared in Mario Kart Super Circuit). Unlike its reappearance in Mario Kart Super Circuit, Star Thwomps make a return in the course. The Thwomps now hit the ground and cause the road to move in a wave-like motion that the player could do tricks off of. Ramps are also added throughout the course. There is also a starry background rather than it being completely black; in actuality, this was implemented earlier in Mario Kart: Super Circuit.

''Mario Kart 64
Rainbow Road is the longest race course in Mario Kart 64 at 2,000 meters and requiring around two minutes per lap. The track differs from the other Rainbow Roads in that it has rails throughout the track. The track features a transparent multi-colored path and with star-shaped rails running throughout the course. Neon-light pictures of the eight playable characters, plus a portrait of a Boo and a Mushroom in the distance, float in the void. Moreover, a big three-dimensional smiling star lies in a section of the track. Roving Chain Chomps slide through the course in reverse, tossing into the air any driver who touches them.

The twisting course starts with a huge drop followed by a gentle uphill stretch, passing through a rainbow ring halo. After the ring, racers behold the flashing neon portraits while run through a pigtail bridge, following then towards another shallower drop. Racers turn around a corkscrew to reach a hairpin bend, and then a twisting stretch to go back to the checked line finally.

Although this track may easily be the easiest Rainbow Road track (thanks to the railings), racers can perform a large shortcut by making a timed hop to the left (or right, during Extra) during the drop at the beginning.

F-Zero X has a track that imitates this Rainbow Road, having the same map of the track, and following it basically. It is described as a "Psychedelic Experience". Parts, though not all of it, are rainbow-colored. Unlike the original, it has no barriers in certain areas, and the neon Mario series decor is missing - instead, it just has a plain black background with a watery blue bottom to which careless drivers may fall. In addition, when racing the track with the 64DD expansion features, the background song is a heavy metal version of the Rainbow Road song heard in Mario Kart 64. Of course, there aren't any Chain Chomps.

Instruction Manual Description
''This course can be described in a word -- LONG, very long. It is simply the longest of all the courses. As the name indicates, the road is made of rainbow and it has a fantastic view of neon sculptures twinkling in the distance. The final course of the Special Cup, it is definitely worth seeing. It is advisable to slow down to avoid the Chomps that will attack.''

''Mario Kart: Super Circuit
In Mario Kart: Super Circuit, Rainbow Road has rails at the start line. Edges of the course are lined with bounce-jumps. Astute racers can use Mushrooms to perform significant shortcuts. The track has falling stars that can make racers spin out and Thunder Clouds that will shrink anyone careless enough to drive under them. Bowser's Castle from Paper Mario can be seen in the background. This track is equal with the course of Rage Racer Overpass City. This game also features the Rainbow Road course from Super Mario Kart without the flashing Thwomps.

''Mario Kart: Double Dash!!
Dash Panels give a boost of speed to the racers in the Mario Kart: Double Dash!! version of Rainbow Road. This version of Rainbow Road also has rails in parts of the course. It features a helix and a pipe that shoots players to the highest point of the track after reaching the very bottom. It also contains floating sculptures of items, and rains stars that racers can pick up. It has the most pearl-like colors of all the Rainbow Roads. Depending if the mode is in split-screen or not, Rainbow Road will take place either over a city or in deep space. The city located below the course could be Mushroom City, according to the design of some of the buildings. When playing in split screen mode, the city and the item sculptures are removed. The final part of the theme music played in the course is a remix of part of the Rainbow Road theme from Mario Kart 64, and reappears in Super Smash Bros. Brawl as an alternative music theme for the Mario Circuit battle stage. In the All-Cup Tour, it is always the final race to compete in.

It is interesting to note that the player can see the reflection of clouds in the track, but no clouds appear in the sky.

Course Layout
The track begins just before a ramp with a boost panel on it, which sends the player flying into a somewhat straight, downhill section of a track. This part of the track tends to be very bumpy and causes Shells and Eggs to bounce around, which hinders their homing skills. After a slight curve to the right and a straight road, there is a sharp U-turn to the left that leads to a short and straight section, then a U-turn to the right and another straight road, that soon leads into a boost ramp that sends the player flying. The ramp actually leads to a road lower than the previous, both with lengthy boost panels on a straight road that leads the player into a helix with boost panels on it.

The helix spirals upwards to the left. Boost Panels and Item Boxes are present in this helix. The boost panels can help the player speed up, or help the player plummet to their doom until Lakitu saves them. Past the long helix is a bump road that is straight, but then waves near the end of the long straight road. The road is also very bumpy here and shooting stars hit here and become Stars for the player to play around with and screw up the other racer's progress by knocking them over the cliff. Past the wavy road is a curve to the left and a pipe. Any item thrown in the pipe gets destroyed and players are invincible when blasted up the pipe.

At the end of the pipe, the player falls down and hits another boost. The boost sends the player into a long road, also with a lot of small boosts that can help or hinder the player. Stars can also spawn here. After this straight road is a ramp with boost panels on it, and it leads the player to a downwards helix. The downwards helix is sharper and shorter than the previous one, and it leads the player into the finish line again, which starts the cycle again and another lap.

Official Description

 * Official Website: “The longest, and most treacherous, course in Mario Kart, Rainbow Road is a wild ride unlike any other. Its hypnotic curves and stomach-turning drops are enough to shake even the steadiest racers.”

''Mario Kart DS
The Rainbow Road of Mario Kart DS has several rails on certain curves and includes a loop and a corkscrew. Those elements may have been added to ensure challenge; players can place items so their opponents could fall off the corkscrew or the loop. Some multi-colored Pipes and Stars appear in the surroundings of the stage. Additionally, the coloring pattern of this looks different from the other previous Rainbow Roads: here, the stripes on the track follow along it, instead of crossing the track. However, there are glitches on the corkscrew and the loop. If a player drifts and hits the rail or continues touching the rail it could send the player floating up, putting them off the track.

Course Layout
The track starts out with three boost pads. There are four item boxes laid out across the track and a spiraling bend to the left while going upward, with four boost pads close to the left edge. There are four more item boxes with the loop close after. A right turn comes next with a small drop, four more item boxes, and a sharp turn to the left. After a short, straight road is a U-turn right. The corkscrew is next, with a slight curve to the right, four item boxes, and another U-turn to the left. With the finish line just ahead, the cycle is started again two more times.

''Mario Kart Wii
The Rainbow Road of Mario Kart Wii is a new version of the rainbow-colored track. The track is located over the eastern parts of North America, as well as parts of Europe, Africa, and South America. If the player happens to fall off in this track, they will burn up in the atmosphere, no matter if there is a section of the course below them before getting picked up by Lakitu. This course has a Super Mario Galaxy theme to it, and it even includes floating Star Bits and a part of a Super Mario Galaxy musical piece, Good Egg Galaxy's background music. A large galaxy can be seen on the background, plus sunlight on the Earth's surface. This course also happens to be Rosalina's expert staff ghost course.

Course Layout
The course begins on a near 90 degree slope, located after the starting line. Light drivers are easy to push off in this area, since there are no walls that can help the player from falling off. Three boost panels are present in this slope. One stretches across the road while the other two are spread apart from each other, such as one being on the right while the other boost panel is on the left, depending on the mode. After the slope is a ramp with a boost panel in it and a sharp turn left. Any vehicle that performs a trick has a risk of falling off on the right end; the worse the drift/handling rating, the more likely the player will fall off.

After the first curve are three more boost panels that stretch across the road and a half-pipe ramp on the very right, plus a turn left. The half-pipe contains floating item boxes for the player to use. After the left turn is a slightly wavy road, in which the player may perform tricks on. Each lap, the road gets wavier, allowing for more tricks to be performed. After the wavy part is a ramp with a boost panel on it, for the player to speed up and perform a trick. The player will then see a very straight road, with two giant holes in the center for the player to fall through. Half-pipe ramps are located to the left and right of these holes, and the player may perform a stunt on the edges of these holes, since the edges of these holes contains small ramps. Both holes contain half-pipe ramps, but the latter one later on doesn't have any item boxes on top of them.

After this area is a turn left, then a curve right that has item boxes lying across the road. After the item boxes is the Launch Star which will lead the player, in very high speeds, to the other part of the course. When the player gets out of the Launch Star, there is a very minor twist in the road and a half-pipe ramp that leads the player into another section of the track, making a broad turn right for the player. After this particular ramp is two roads, which split and merge later on in the track. Both will make the player end up in the same area, but one is more elevated than the other and has boost pads in different locations. Both will lead to a ramp with two boost panels on it, with floating item boxes. Past the ramp is where the road merges again. This part has more boost panels with a sharp curve to the left and to the right. The boost panels may give the player an edge or throw the player off course and off the track. Past this area is the finish line, which starts the track over and another lap. It is the longest nitro course, and one of the longest tracks.

Mario Kart Wii Trading Card Description
''The layout of Rainbow Road has changed over the years as it has appeared in a variety of incarnations; the challenge factor has always been high. It's a long track with plenty of opportunities to fall off into space. In Mario Kart Wii, at least one of those opportunities can become a shortcut if you play it right.''

Competitions
The November 2009 second competition took place at Rainbow Road. Players had to race three laps, while avoiding the Chain Chomps and Incoming Chomps. The players started the race with a set of Triple Mushrooms. The official description stated, "Anticipating their movements and avoiding them is the key to a good score." This could be a reference to the Mario Kart 64 track, as Chain Chomps were present there. The competition was restricted to karts only.

This competition was repeated as the first competition of December 2010, but there were no restrictions. It was later repeated as the second competition of August 2011, with the karts only restriction still in tact.

''Mario Kart 7
The Rainbow Road is featured once more in a new incarnation in Mario Kart 7 and it is again made up of multi-colored tiles. It also shows planets and rockets in the background. This incarnation of Rainbow Road, along with the tracks Wuhu Island Loop and Wuhu Mountain Loop only has one lap instead of three. It is divided into three sections to resemble laps, with banners at the end of each section.

Unlike past Rainbow Roads, this incarnation features the player driving on non-rainbow tile surfaces such as the moon and rings of a planet. The first part has the drivers race on the rainbow tiles and the second part has them race on the rings of a planet for a short time. The third part brings them to the moon with Chomps coming out of the craters. Like in Mario Kart: Double Dash!!, the music on the course is a remix of Mario Kart 64's Rainbow Road. There are 2 different variations of this new theme. The 1st variation plays while driving on the rainbow tiles, and the 2nd variation plays during the 2nd section when the player is driving on the Moon.

''Mario Hoops 3-on-3
Rainbow Road is the unlockable third dribble race from the "challenges" section in the basketball game Mario Hoops 3-on-3. However, this Rainbow Road floats above the clouds and around a clock tower, and not much of the course is fully seen when playing. Podoboos and Bombs come out of holes similar to Bowser's Castle Court.

''Super Mario Galaxy 2
In Super Mario Galaxy 2, Rainbow Road appears in the Rolling Coaster Galaxy in the mission called the "Rainbow Road Roll", and also a purple coin challenge, but it is very different than in its previous appearances. While it does retain its appearance, it's curved and appears to be made up of rainbow tiles instead of the colors simply being contiguous, much like the Rainbow Road from Super Mario Kart in which the track was also made up of rainbow tiles. Instead of just the Rainbow itself, it also has several platforms shaped both like mushrooms and squares with different colors. Along the way, Mario or Luigi must avoid several obstacles like towers and Bob-ombs. Also, the two brothers can earn two Power Stars for finishing the course, one for the normal mission, and another for collecting 100 of the 110 Purple Coins. The music played when riding on Rainbow Road is a remix of the music played on the The Princess's Secret Slide in Super Mario 64.

Trivia

 * F-Zero GX also has a track similar to Rainbow Road called the "Phantom Road", but this one doesn't take place in a starry night sky or the cosmos like most Rainbow Roads, it takes place in a psychedelic cybernetic void of sorts. In addition, the track has only one color that constantly shifts through the color spectrum as opposed to having the traditional rainbow-looking appearance.
