is a poolgame popular in much of the world, and the subject of international professional and amateur competition. Played on a pool table with six pockets, the game is so universally known in some countries that beginners are often unaware of other pool games and believe the word “pool” itself refers to eight-ball. The game has numerous variations, mostly regional. Standard eight-ball is the second most competitive professional pool game, after nine-ball, and for the last several decades ahead of straight pool.

Eight-ball is played with cue sticks and 16 balls: a cue ball, and 15 object balls consisting of seven striped balls, seven solid-colored balls and the black 8 ball. After the balls are scattered with a break shot, the players are assigned either the group of solid balls or the stripes once a ball from a particular group is legally pocketed. The ultimate object of the game is to legally pocket the eight ball in a called pocket, which can only be done after all of the balls from a player’s assigned group have been cleared from the table.
