Pool is a classification of cue sports played on a table with six pockets along the into which balls are deposited. Each specific pool game has its own name; some of the better-known include eight-ball, eightball pool and its variant blackball, nine-ball, ten-ball, seven-ball, straight pool, one-pocket, and bank pool. The generic term pocket billiards is sometimes also used, and favored by some pool-industry bodies, but is technically a broader classification, including games such as snooker, Russian pyramid, and kaisa, which are not referred to as pool games. In most parts of the world, it is commonly referred to as just "billiards", analogous to the term "bowling" being commonly used to refer the game of ten-pin bowling. There are also hybrid games combining aspects of both pool and carom billiards, such as American four-ball billiards, bottle pool, cowboy pool, and English billiards.
