pool

An American table game played in many forms. It uses 16 balls, and a cue similar to that used in billiards and snooker. The most popular form is the variation known as 8-ball pool. The object is to sink all balls of a certain design (usually striped or solid), and then finally the black ball (the No. 8 ball, hence the name). It is played on a table approximately half the size of a standard billiard table, with six round pockets.
