Courses

Five Courses

1
SUNSET CITYTwilight Downtown

2
NEON HARBORRainy Waterfront
A midnight pier. Wet asphalt mirrors the neon on this high-speed layout
3
RIDGE PASSMountain Pass at Dawn
Winding mountain roads at daybreak. Elevation changes and tight corners back to back
4
DUNE HIGHWAYScorching Desert Road
One straight road under the moon. Nothing but tire tracks in the cold sand — the fastest course
5
SHRINE REALMNight-Blossom Shrine
From the approach to the main hall, a thousand torii gates, the pagoda, and the inner sanctum — a stone-paved sacred circuit

Every course is a three-lap race against seven rivals, including academy friends Kuroko, Chappy and Gemi-chan. Your best lap is saved in the browser, so come back and beat your own record.
