Skyscraper

Skyscraper is a battle course in Mario Kart 64. The battle takes place on the roof of a giant skyscraper, making it possible to bump opponents off the stage. There are several gaps in the roof, making it easy to accidentally fall off and lose a balloon.

Mario Kart Wii
Skyscraper returns in Mario Kart Wii. In the stage's Wii version, it was made larger to accommodate 12 players. The edges of the gaps in the roof became ramps on which players can perform tricks. Areas 1-4 are also re-ordered clockwise instead of having 1-2 and 3-4 parallel to each other (based on players' starting positions), and have become color-coded yellow, green, cyan, and magenta.

Tournaments
In Mario Kart Wii, a tournament took place on this battle course, where the course was made into a race track. Players had to do a time trial around the track, while avoiding the Bob-omb Cars from Moonview Highway. The control scheme was restricted to Wii Wheel users. It was the first tournament of September 2008, and it was later repeated as the first tournament of September 2010, the first tournament of February 2012, and the second tournament of April 2013.

 * Instruction booklet: "It's a wild battle on top of the skyscraper! If you fall off the building, you will lose one balloon. There are no guardrails to keep you from falling, so don't speed too much. A highly effective strategy for attacking your opponents is to crash into them in an attempt to knock them off instead of relying simply on the use of items."
 * Web page: "The Skyscraper arena is situated high atop a skyscraper. If you fall off the building, you will lose one of your balloons. Heavier Karts can knock lighter ones off the roof without using an item. Since this arena is the smallest of all, you can't hide, and it's a good idea to keep your speed down. It's also easy to ambush you opponent when he is put back on the course by Lakitu."
