Cue Online is a realistic 3D pool simulation game with a focus on competitive billiards games. Nominated as "The Best Game of the Month" in March, 2007 by Korean Ministry of Culture and Tourism, Electronic News and The Games in Korea, Cue Online is developed by Happy Nation and features pinpoint control and physics through the design of its own custom-developed game engine.

Cue Online focuses on competitive billiard games including straight pool, nine-ball, eight-ball, carom and three-cushion billiards. Happy Nation's exclusive engine was designed to create the most realistic billiards game to date. For example, ball movement will take into account each player's style, including stroke power, table contact, spin and strike quality against other balls, the cloth friction of the table and more.

Thanks to the development team's many years of research and development in optimizing the physics of billiards game play, even highly demanding skill players will be impressed with the realistic physics when playing Cue Online. With players able to make trick shots with Masse and fault shots such like Double hits and Miscues, Cue Online is truly recreates a genuine pool experience.
