[1] Initially developed as a school project of a Korean student known as Comworm, it is a multiplayer online simulation of pool and billiards.

[2] Carom 3D is at least in part an accurate simulation of eight-ball, nine-ball, rotation pool, three-ball, four-ball and original six-ball.

It progressively became a free-to-play game with bonus items (cues, custom 3D character and profile, participation to daily tournaments) sold from 1 to US$5.

Winning allows a player to get a better cue needed to perform high strength and full spin shots.
