GBA Luigi Circuit

Luigi Circuit is a unique track in Mario Kart: Super Circuit in that it is the only Circuit course not to be the starting course for the game. Further, this version holds the distinction of being the first Mario Kart track to ever take place in the rain.

This course is the first in the Lightning Cup and is set on what appears to be an airfield filled with rain puddles during a downpour, which when driven through cause drivers to spin out. In the background are hangars numbered "64" and "65", flanking a radio control building. In the third lap, a Luigi blimp takes off and flies around (the same blimp can be seen in Sky Garden). The course features many tight turns and winds around circuitously several times.

Course layout
This course starts on a straight road and that soon leads the player into a small curve to the right. Past that curve is another curve to the right, that soon leads into a tight U-turn that winds to the right. After the U-turn is a straight road that soon curves slightly to the left, which then leads to another slight curve to the right.

Past the right curve is a small U-turn to the right that leads into a straight road. After that small straight road is a tight turn to the left that leads into another straight road, this time longer than the last. After that straight road, there is a loose U-turn to the right that has a wavy road when the player proceeds. The road isn't too wavy, but it isn't straight either. Past the longest, straight road on the track is a sharp curve to the left that leads into another straight road. A U-turn then comes, making the player turn left and into the straight road, that has a finish line in it. This is where the track layout restarts, only that another lap has passed.

Mario Kart DS version
The Mario Kart DS port is the same excluding a few background details that have been modified to be three-dimensional, and the two hangers were changed into 00's. The rain now also appears to be flying at the screen, as it would if one were passing through it at high speed. The course is not available in Wi-Fi mode.
