Billiards grew to the extent that by 1727, it was being played in almost every Paris café. In England, the game was developing into a very popular activity for members of the gentry. By 1670, the thin butt end of the mace began to be used not only for shots under the cushion (which itself was originally only there as a preventative method to stop balls from rolling off), but players increasingly preferred it for other shots as well. The footless, straight cue as it is known today was finally developed by about 1800. Initially, the mace was used to push the balls, rather than strike them. The newly developed striking cue provided a new challenge. Cushions began to be stuffed with substances to allow the balls to rebound, in order to enhance the appeal of the game. After a transitional period where only the better players would use cues, the cue came to be the first choice of equipment. The demand for tables and other equipment was initially met in Europe by John Thurston and other furniture makers of the era. The early balls were made from wood and

; and others. In the United States, pool and billiards had died out for a bit, but between 1878 and 1956 the games became very popular. Players in annual championships began to receive their own cigarette cards. This was mainly due to the fact that it was a popular pastime for troops to take their minds off from battle. However, by the end of World War II, pool and billiards began to die down once again. It was not until 1961 when the film ''The Hustler'' came out that sparked a new interest in the game. Now the game is generally a well-known game and has many players of all different skill levels.

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 ( 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 ( 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 ( 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

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).

Cloth

All types of tables are covered with billiard cloth (often called "felt", but actually a woven wool or wool/nylon blend called

baize Baize is a coarse woollen (or in cheaper variants cotton) cloth, similar in texture to felt, but more durable. History A mid-17th-century English ditty—much quoted in histories of ale and beer brewing in England—refers to 1525: Hops, her ...

. 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.

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.

Cues

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

Mechanical bridge

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.

Chalk

Chalk is applied to the tip of the cue stick, ideally before every shot, to increase the tip's friction coefficient so that when it impacts the cue ball on a non-center hit, no (unintentional slippage between the cue tip and the struck ball) occurs. Chalk is an important element to make good shots in pool or

Major games

There are two main varieties of billiard games: carom and pocket. The main carom billiards games are straight rail,

and three cushion billiards. All are played on a pocketless table with three balls; two cue balls and one object ball. In all, players shoot a cue ball so that it makes contact with the opponent's cue ball as well as the object ball. Others of multinational interest are four-ball and

Straight rail

In straight rail, a player scores a point and may continue shooting each time his cue ball makes contact with both other balls. Some of the best players of straight billiards developed the skill to the balls in a corner or along the same rail for the purpose of playing a series of to score a seemingly limitless number of points. The first straight rail professional tournament was held in 1879 where Jacob Schaefer Sr. scored 690 points in a single turn (that is, 690 separate strokes without a miss). With the balls repetitively hit and barely moving in endless "nursing", there was little for the fans to watch.

Balkline

In light of these skill developments in straight rail, the game of balkline soon developed to make it impossible for a player to keep the balls gathered in one part of the table for long, greatly limiting the effectiveness of nurse shots. A is a line parallel to one end of a billiards table. In the game of balkline, the players have to drive at least one object ball past a balkline parallel to each rail after a specified number of points have been scored.

Cushion billiards

Another solution was to require a player's cue ball to make contact with the rail cushions in the process of contacting the other balls. This in turn saw the three-cushion version emerge, where the cue ball must make three separate cushion contacts during a shot. This is difficult enough that even the best players can only manage to average one to two points per turn. This is sometimes described as "hardest to learn" and "require most skill" of all billiards.

, where the lowest-numbered object ball on the table must be struck first, although any object ball may be pocketed (i.e., combination shot). Each pocketed ball is worth its number, and the player with the highest score at the end of the rack is the winner. Since there are only 120 points available (1 + 2 + 3 ⋯ + 15 = 120), scoring 61 points leaves no opportunity for the opponent to catch up.

English billiards

Dating to approximately 1800, English billiards, called simply billiards in many former British colonies and in the UK where it originated, was originally called the ''winning and losing carambole game'', folding in the names of three predecessor games, ''the winning game'', ''the losing game'' and ''the carambole game'' (an early form of straight rail), that combined to form it. The game features both (caroms) and the pocketing of balls as objects of play. English billiards requires two and a red . The object of the game is to score either a fixed number of points, or score the most points within a set time frame, determined at the start of the game. Points are awarded for: *Two-ball cannons: striking both the object ball and the other (opponent's) cue ball on the same shot (2 points). *: the red ball (3 points); potting the other cue ball (2 points). * (or "in-offs"): potting one's cue ball by cannoning off another ball (3 points if the red ball was hit first; 2 points if the other cue ball was hit first, or if the red and other cue ball were "", i.e., hit simultaneously).
