Luigi Circuit
Luigi Circuit is the first race track that appears in Mario Kart: Double Dash!! and later reappears modified in Mario Kart DS. It appears in the Mushroom Cup in Double Dash!! and in the Shell Cup in Mario Kart DS.
The track is a huge 8 with ramps on the sides. Because of this, racers can see other racers going up the track while they are going down. In any setting except for the 50cc one, the racers can even get into contact with each other. Additionally in the higher settings, there are several shortcuts around the track, with Item Boxes on them.
The only threat on the course is the giant Chain Chomp. In the background, a rank "A" mansion from the end of Luigi's Mansion can be seen.
To avoid cheating in the course, the drivers have to pass the booster on both ramps in order to complete the round.
In Mario Kart DS, however, it was modified so that a lot of shortcuts were taken out. All that remained is the basic track and the Chain Chomp.
In the All-Cup Tour in Double Dash!!, it is always the first race.
Mario Kart: Super Circuit also has a Luigi Circuit which is filled with puddles. It rains on the track and there are also numerous shortcuts. This track represented Super Ciruit in Mario Kart DS. It is raced in the Lightning Cup in Super Circuit and in the Leaf Cup in Mario Kart DS.
A Luigi Circuit-like course is Luigi Raceway of Mario Kart 64.
