billiards, any one of a number of games played with a tapered, leather-tipped stick called a cue and various numbers of balls on a rectangular, cloth-covered slate table with raised and cushioned edges. Games similar to billiards were popular in England and France in the 16th cent., and evidence even suggests that a billiardslike game was played in the 14th cent. The country of origin is disputed—England, France, Italy, Spain, and China have been credited by various historians with its invention. The game in its present form was probably fully developed by 1800. There are three main types of billiards: carom billiards, pocket billiards (also known as pool), and snooker. Carom billiards is played with three balls, a cue ball and two object balls, on a pocketless table; scoring is by caroms only, i.e., by causing the cue ball to strike the object balls in specified ways. Pocket billiards is played with 15 object balls and a cue ball on a table with six pockets; the essential object of the game is to cause the object balls to enter the pockets. Snooker is similar to pocket billiards, except that it uses 21 object balls and smaller pockets. There are many additional variations of the basic games, depending on the number of balls used, the positioning of the balls, the boundaries on the table, and the scoring. Among the variations are Chicago, golf, rotation, balk-line, and bumpers. William Frederick Hoppe is generally considered the foremost billiards player of all time.
