Pool is the name given to a series of cue sports played on a billiard table. The table has six pockets along the rails, into which balls are shot. Of the many different pool games, the most popular include: eight-ball, blackball, nine-ball, ten-ball, seven-ball, straight pool, one-pocket, and bank pool. Eight-ball is the most frequently played discipline of pool, and it is often thought of as synonymous with "pool".

Cue sports are a wide variety of games of skill played with a cue, which is used to strike billiard balls and thereby cause them to move around a cloth-covered table bounded by elastic bumpers known as cushions. Cue sports are also collectively referred to as billiards, though this term has more specific connotations in some varieties of English.
