Ride your music! Audiosurf is a puzzle racer where you use your own tracks to create your own experience. The shape, the speed, and the mood of each ride is determined by the song you choose. You earn points for clustering together blocks of the same color on the highway, and compete with others on the internet for the high score on your favorite songs.

Audiosurf is a strong music/rhythm based game that features gameplay that consists of a mix of Tetris and racing. One of the strongest indie games early in the “Steam Era” it is a must for anyone who loves just plain listening to music. However the advent of games like Beat Hazard have dethroned Audiosurf as the defacto king of computer music games.
