SNES Mario Circuit 1

Mario Circuit 1 is the first course of the Mushroom Cup in Super Mario Kart and as such, the first course in the Mario Kart series in general. It was later reused as the first Extra Course in Mario Kart: Super Circuit and the first Retro Course in Mario Kart DS, being the first Retro Course in the series. Later, it reappeared in Mario Kart Tour's New York Tour, with added Reverse and Trick variants. This course also appeared in the Paris, Winter, Holiday, and New Year's Tours, with the Holiday Tour adding the R/T variant.

The only hazard in this level are the Warp Pipes that appear near the second turn of the course. After the player passes the pipes, they find the only set of item boxes in the course. There is also a shortcut a racer can take by driving through the dirt right after passing the item boxes. The player needs either a Mushroom or a Star to successfully implement the shortcut without slowing down. However, taking the shortcut without an item does not take more time than following the course.

Mario Kart: Super Circuit
The course reappears in Mario Kart: Super Circuit, and is the first track in the Extra Mushroom Cup. It uses the background from Peach Circuit. The pipe hazards were removed from the track, but an item box can be found in the shortcut.

Mario Kart DS
Mario Circuit 1 is the first course in the Shell Cup in Mario Kart DS, as well as the first retro course in the series overall. However, the course is slightly longer this time. Mission 1-8 (Perform 4 power-slide turbo boosts in 1 lap!) in this game takes place here. This course was available in Wi-Fi.

Official descriptions

 * Official website and Mario Kart DS instruction booklet: “Pulled straight from the SNES version of Super Mario Kart, this narrow track is further complicated by the pipes that protrude from its surface.”
 * Official European website: “The one that started it all. The first track from the original Super Mario Kart has a simple layout but don’t let that fool you. Veteran racers know that pixel-perfect precision is needed to negotiate this track’s turns without hitting the pipes jutting from the ground.”
