Pool (cue sports)
Pool, also known as pocket billiards, is the general term for a family of cue sports. These games are played on a pool table with six holes cut into them called pockets. One of the main goals of the game is to "sink" all the balls into the pockets. ("Sinking" the ball means that the ball rolls into a pocket.) There are many different types of pool, including eight-ball, nine-ball, and straight pool.
