There are hundreds of pool games. Some of the more well known include eight-ball, nine-ball, straight pool, and one-pocket. The game of snooker is played on a table with pockets but is considered separate from pool. It is governed internationally by the World Professional Billiards and Snooker Association (professional) and the International Billiards and Snooker Federation (amateur). There are also hybrid games combining traits of both pool and carom billiards, such as English billiards, American four-ball billiards, cowboy pool and bottle pool.
