DS Luigi's Mansion

Luigi's Mansion is the last race course of the Mushroom Cup in the game Mario Kart DS. Outside the mansion is Boo Woods which has a graveyard surrounding the mansion and beyond it, a swamp of mud with moving trees. When a character runs into one of these trees, instead of spinning out or rolling over, the character instead will just get stuck on the tree as if it were a wall.

Racers start outside the mansion in a section of Boo Woods, and they will go through a curl path to the entrance of the mansion, running along a narrow hall that leads the racers downwards to a room beneath the lobby. Various portraits of portrait ghosts from Luigi's Mansion can be seen hanging on the walls. The racers then go out of the mansion, crossing a stone path tunnel, where they reach the graveyard, leaving the mansion. Finally, racers end up crossing the swamp to cross the checkered line.

Luigi's Mansion is the only Luigi-themed race course in the series that is not a circuit-type course. While it does not appear in Mario Kart 8 Deluxe, a remix of its music is used for the GCN Luigi's Mansion battle course.

Missions
Missions 1-6 and 2-4 take place on this course, with Luigi driving in both of them.

In mission 1-6, the player has to exit the mansion in reverse, and in mission 2-4 the player must destroy 5 item boxes.

Mario Kart 7
Luigi's Mansion appears as a Retro course in Mario Kart 7 as the final track in the Shell Cup. The only changes are the ramp that lets racers use gliders, and the Boo and the portraits are replaced by solo arts of Boo who attempt to pop out when the racer passes. The mansion's foyer has been redesigned to more closely resemble its original appearance, instead of the relatively simple single-story room seen in Mario Kart DS. Also, there is a glider ramp towards the end of this course in the muddy swamp and another glider ramp is added in the graveyard section. Additionally, part of the gate wall leading to the swamp is broken as a small shortcut to cross through with one Mushroom.

The Boos that pop out of the portraits in were originally going to appear in Mario Kart DS.

Mario Kart Tour
Luigi's Mansion reappears in Mario Kart Tour. The track mainly uses features from its 3DS appearance, with graphic improvements, and the area was given a tint of blue. Similar to Mario Kart 8, the Mario Kart logo uses a modern design instead of its classic design. The moon now has a bluish-white color, and the finish line banner has a new design. This course is a favorite of Luigi, King Boo, Rosalina (Halloween), Mario (Santa), Mario (Chef), Luigi (Lederhosen), Wario (Hiker), King Boo (Gold), and Shy Guy (Ninja). It is also a favorite of Kamek if he is at level 3, and Peachette, Mario (Musician), and Waluigi (Bus Driver) if they are at level 6. As with other courses in the game, Luigi's Mansion has an R version, a T version, and an R/T version referred to as Luigi's Mansion R, Luigi's Mansion T and Luigi's Mansion R/T respectively; the former two were introduced alongside the regular version in the 2019 Halloween Tour, while the latter was added in the London Tour.

 * European website bio: "After rescuing Mario from the dark dungeons of this dreary old place, Luigi has decided to make some money from his mansion by turning it into a racetrack. Perpetual darkness means you'll need your headlights on for this one, especially since the trees have a tendency to walk around..."
