SNES Rainbow Road

Rainbow Road is a race course that first appeared in Super Mario Kart, and as a retro track in Mario Kart: Super Circuit, Mario Kart 7, and The Legend of Zelda X Mario Kart 8 DLC pack for Mario Kart 8.

Appearance in Super Mario Kart
Rainbow Road is unique in the fact that it is the only track in the game that is not numbered compared to the others, and thus it is the game's only unique track. Despite being the final track of the game, it is relatively short compared to other tracks in the game and it is also the shortest Rainbow Road to date. It is also the only track in the Special Cup with normal traction. Rainbow Road also lacks rails entirely and has only 90-degree turns. Rainbow-colored tiles cover the track's surface, and the yellow tiles conceal Coins and jumping bumps. 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.

The track begins with racers taking a turn to the right, where they will find ? Panels to gather items. There are some jumping bumps that might be a hindrance as there is a quartet of Star Thwomps ahead with a very tight space between them for racers to pass, although racers can also pass on the sides of the Thwomps. After this, racers turn to the right again where they can collect some coins, followed by another turn to the right, where there is once again a path with jumping bumps with an incoming turn that might cause racers to fall. After this turn, the track gets narrower and follows a long path where more coins and Star Thwomps are found along the way with another turn awaiting the player. It is here where the track gets even more narrow increasing the risk of falling. Before the final turn, the track splits into two roads; the left side contains coins while the right side has 2 ? Panels, both have a pair of Star Thwomps near the part where these roads merge. Alternatively, there is a jumping bump in the middle gap; if any racers use a Mushroom while they are heading it, they can jump over the gap for a significant shortcut. After the final turn, before the finish line, there is another quartet of Star Thwomps, but this time there is no space between them to pass, with players only being able to pass them by driving on the side or when the Star Thwomps are rising.

Appearance in Mario Kart: Super Circuit
Rainbow Road reappeared in Mario Kart: Super Circuit, as the last track of the Extra Special Cup. The background is from GBA Rainbow Road, but with only the sparkles, foreground clouds, and moon appearing. The Star Thwomps and the jumping bumps were removed.

Appearance in Mario Kart 7
Rainbow Road returned again 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 (besides its reappearance in Mario Kart: Super Circuit). Even though this track is short, and is one of the shortest tracks in the game, there are only three laps instead of five. While keeping the original layout, the red tiles are now pink, and the turquoise tiles are now cyan. Unlike Super Circuit, Star Thwomps return. They are bigger (which reduces their number in the track, from 16 to seven), and now form undulations on the track upon landing, which the player can Trick off of. Also, howling noises can be heard near the Star Thwomps. Ramps also replace the yellow bumps, though the first two bumps were removed entirely, and a ramp was added on the inside of the second U-turn. In first-person view, the player can see the stars in the background through the breaks in the tiles.

Appearance in Mario Kart 8


Rainbow Road will return for the third time in the DLC pack 1 of Mario Kart 8, appearing as the second course in the Triforce Cup. The track looks similar to its appearance in Mario Kart 7. The color of the tiles are the same as they were in the original appearance, but this time they have a neon appearance, the tiles' pattern is reversed, and the Star Thwomps now turn the tiles they land on white. The course now takes place in the sky with the moon visible, just like in Mario Kart: Super Circuit (and presumably above SNES Donut Plains 3), but it now has color-changing hills that stick above them. The Star Thwomps are the same as they were in Mario Kart 7. Unlike before, when they start to crash down, they will create rainbow waves above them. The waves on the track they create are now bigger. The starting banner is now redesigned, as differently-colored blocks with a star on top of it.
