In Mario Kart: Super Circuit, Rainbow Road includes jump pads that border most of the track. There's only one place that has a solid wall. It introduces boost pads as well, making it the first version with boost pads. There are clouds around the track that will drop fake Starman that will make the player spin out upon contact.
This version is reminiscent of the Super Mario Kart version, due to its flat terrain and short length, but with the Thwomps removed and contain more sharp turns. Shortcuts can be taken by using Mushrooms to bounce off of the yellow jump pads to land the other side.
