Table games using cues and billiard balls

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 Cue sports are also collectively referred to as billiards, though this term has more specific connotations in some varieties of English. There are three major subdivisions of games within cue sports:
Carom billiards, played on tables without , typically ten feet in length, including straight rail, balkline, one cushion carom, three cushion billiards, artistic billiards, and four ball
Pocket billiards (or pool), played on six pocket tables of seven, eight, nine, or ten foot length, including among others eight ball (the world's most widely played cue sport), nine ball (the dominant professional game), ten ball, straight pool (the formerly dominant pro game), one pocket, and bank pool
Snooker, English billiards, and Russian pyramid, played on a large, six pocket table (dimensions just under 12 ft by 6 ft), all of which are classified separately from pool based on distinct development histories, player culture, rules, and terminology. Billiards has a long history from its inception in the 15th century, with many mentions in the works of Shakespeare, including the line "let's to billiards" in Antony and Cleopatra (1606–07). Enthusiasts of the sport have included Mozart, Louis XIV of France, Marie Antoinette, Immanuel Kant, Napoleon, Abraham Lincoln, Mark Twain, George Washington, Jules Grévy, Charles Dickens, George Armstrong Custer, Theodore Roosevelt, Lewis Carroll, W. C. Fields, Babe Ruth, Bob Hope, and Jackie Gleason.

All cue sports are generally regarded to have evolved into indoor games from outdoor stick and ball lawn games, specifically those retroactively termed ground billiards, and as such to be related to the historical games jeu de mail and palle malle, and modern trucco, croquet, and golf, and more distantly to the stickless bocce and bowls. The word billiard may have evolved from the French word billart or billette, meaning 'stick', in reference to the , an implement similar to a golf putter, and which was the forerunner to the modern cue; however, the term's origin could have been from French bille, meaning 'ball'. The modern term cue sports can be used to encompass the ancestral mace games, and even the modern cueless variants, such as finger billiards, for historical reasons. Cue itself came from queue, the French word for 'tail'. This refers to the early practice of using the tail or butt of the mace, instead of its club foot, to strike the ball when it lay against a .

The games with regulated international professional competition, if not others, have been referred to as "sports" or "sporting" events, not simply "games", since 1893 at the latest. Quite a variety of particular games (i. e., sets of rules and equipment) are the subject of present day competition, including many of those already mentioned, with competition being especially broad in nine ball, snooker, three cushion, and eight ball. Snooker, though a pocket billiards variant and closely related in its equipment and origin to the game of English billiards, is a professional sport organized at an international level, and its rules bear little resemblance to those of modern pool, pyramid, and other such games. A "Billiards" category encompassing pool, snooker, and carom has been part of the World Games since 2001.

Billiard balls vary from game to game, in size, design and quantity. Russian pyramid and kaisa have a size of 68 mm (2 11/16 in). In Russian pyramid there are 16 balls, as in pool, but 15 are white and numbered, and the is usually red. In kaisa, five balls are used: the yellow (called the kaisa in Finnish), two red object balls, and the two white cue balls (usually differentiated by one cue ball having a dot or other marking on it and each of which serves as an object ball for the opponent). Carom billiards balls are larger than pool balls, having a diameter of 61.5 mm (2 7/16 in), and come as a set of two cue balls (one colored or marked) and an object ball (or two object balls in the case of the game four ball). Standard pool balls are 57.15 mm (2 1/4 in), are used in many pool games found throughout the world, come in sets of two of object balls, seven and seven , an and a ; the balls are racked differently for different games (some of which do not use the entire ball set). Blackball (English style eight ball) sets are similar, but have unmarked of and balls instead of solids and stripes, known as "casino" style. They are used principally in Britain, Ireland, and some Commonwealth countries, though not exclusively, since they are unsuited for playing nine ball. The diameter varies but is typically slightly smaller than that of standard solids and stripes sets. Snooker balls are smaller than American style pool balls with a diameter of 52.5 mm (2 1/16 in), and come in sets of 22 (15 reds, 6 "", and a cue ball). English billiard balls are the same size as snooker balls and come in sets of three balls (two cue balls and a red object ball). Other games, such as bumper pool, have custom ball sets. Billiard balls have been made from many different materials since the start of the game, including clay, bakelite, celluloid, crystallite, ivory, plastic, steel and wood. The dominant material from 1627 until the early 20th century was ivory. The search for a substitute for ivory use was not for environmental concerns, but based on economic motivation and fear of danger for elephant hunters. It was in part spurred on by a New York billiard table manufacturer who announced a prize of $10,000 for a substitute material. The first viable substitute was celluloid, invented by John Wesley Hyatt in 1868, but the material was volatile, sometimes exploding during manufacture, and was highly flammable.

There are many sizes and styles of billiard tables. Generally, tables are rectangles twice as long as they are wide. Table sizes are typically referred to by the nominal length of their longer dimension. Full size snooker tables are 12 feet (4 m) long. Carom billiards tables are typically 10 feet (3 m). Regulation pool tables are 9 feet (3 m), though pubs and other establishments catering to casual play will typically use 7 feet (2 m) tables which are often coin operated, nicknamed Formerly, ten foot pool tables were common, but such tables are now considered antiques. High quality tables have a made of thick slate, in three pieces to prevent warping and changes due to temperature and humidity. The slates on modern carom tables are usually heated to stave off moisture and provide a consistent playing surface. Smaller bar tables are most commonly made with a single piece of slate. Pocket billiards tables of all types normally have six pockets, three on each side (four corner pockets, and two side or middle pockets).

All types of tables are covered with billiard cloth (often called "felt", but actually a woven wool or wool/nylon blend called baize). Cloth has been used to cover billiards tables since the 15th century. Bar or tavern tables, which get a lot of play, use "slower", more durable cloth. The cloth used in upscale pool (and snooker) halls and home billiard rooms is "faster" (i. e., provides less friction, allowing the balls to roll farther across the table ), and competition quality pool cloth is made from 100% worsted wool. Snooker cloth traditionally has a nap (consistent fiber directionality) and balls behave differently when rolling against versus along with the nap. The cloth of the billiard table has traditionally been green, reflecting its origin (originally the grass of ancestral lawn games), and has been so colored since at least the 16th century, but it is also produced in other colors such as red and blue. Television broadcasting of pool as well as 3 Cushion billiards prefers a blue colored cloth which was chosen for better visibility and contrast against colored balls.

A rack is the name given to a frame (usually wood, plastic or aluminium) used to organize billiard balls at the beginning of a game. This is traditionally triangular in shape, but varies with the type of billiards played. There are two main types of racks; the more common triangular shape which is used for eight ball and straight pool and the diamond shaped rack used for nine ball. There are several other types of less common rack types that are also used, based on a "template" to hold the billiard balls tightly together. Most commonly it is a thin plastic sheet with diamond shaped cut outs that hold the balls that is placed on the table with the balls set on top of the rack. The rack is used to set up the "break" and removed once the break has been completed and no balls are obstructing the template.

Billiards games are mostly played with a stick known as a cue. A cue is usually either a one piece tapered stick or a two piece stick divided in the middle by a joint of metal or phenolic resin. High quality cues are generally two pieces and are made of a hardwood, generally maple for billiards and ash for snooker. The end of the cue is of larger circumference and is intended to be gripped by a player's hand. The of the cue is of smaller circumference, usually tapering to an terminus called a (usually made of fiberglass or brass in better cues), where a rounded leather is affixed, flush with the ferrule, to make final contact with balls. The tip, in conjunction with chalk, can be used to impart spin to the cue ball when it is not hit in its center. Cheap cues are generally made of pine, low grade maple (and formerly often of ramin, which is now endangered), or other low quality wood, with inferior plastic ferrules. A quality cue can be expensive and may be made of exotic woods and other expensive materials which are artfully inlaid in decorative patterns. Many modern cues are also made, like golf clubs, with high tech materials such as woven graphite. Recently, carbon fiber woven composites have been developed and utilized by top professional players and amateurs. Advantages include less flexibility and no worry of nicks, scratches, or damages to the cue. Skilled players may use more than one cue during a game, including a separate cue with a hard phenolic resin tip for the opening break shot, and another, shorter cue with a special tip for .

The mechanical bridge, sometimes called a "rake", "crutch", "bridge stick" or simply "bridge", and in the UK a "rest", is used to extend a player's reach on a shot where the cue ball is too far away for normal hand bridging. It consists of a stick with a grooved metal or plastic head which the cue slides on. Some players, especially current or former snooker players, use a screw on cue butt extension instead of or in addition to the mechanical bridge. Bridge head design is varied, and not all designs (especially those with cue shaft enclosing rings, or wheels on the bottom of the head), are broadly tournament approved. In Italy, a longer, thicker cue is typically available for this kind of tricky shot. For snooker, bridges are normally available in three forms, their use depending on how the player is hampered; the standard rest is a simple cross, the 'spider' has a raised arch around 12 cm with three grooves to rest the cue in and for the most awkward of shots, the 'giraffe' (or 'swan' in England) which has a raised arch much like the 'spider' but with a slender arm reaching out around 15 cm with the groove.

Snooker is a pocket billiards game originated by British officers stationed in India during the 19th century, based on earlier pool games such as black pool and life pool. The name of the game became generalized to also describe one of its prime strategies: to "" the opposing player by causing that player to foul or leave an opening to be exploited. In the United Kingdom, snooker is by far the most popular cue sport at the competitive level, and major national pastime along with association football and cricket. It is played in many Commonwealth countries as well, and in areas of Asia, becoming increasingly popular in China in particular. Snooker is uncommon in North America, where pool games such as eight ball and nine ball dominate, and Latin America and Continental Europe, where carom games dominate. The first World Snooker Championship was held in 1927, and it has been held annually since then with few exceptions. The World Professional Billiards and Snooker Association (WPBSA) was established in 1968 to regulate the professional game, while the International Billiards and Snooker Federation (IBSF) regulates the amateur games.
