Seven-ball is a rotation pool game with rules similar to nine-ball, though it differs in two key ways: the game uses only seven object balls as implied by its name, and play is restricted to particular pockets of the table. William D. Clayton is credited with the game's invention in the early 1980s. [1]
At the start of the game, balls one through seven are racked in a hexagonal configuration, with the 1-ball placed at the rack's apex , centered over the table's foot spot , the 7-ball placed at the rack's center, and all other balls placed clockwise (see photo top right). Immediately following the break shot , the opponent must elect three pockets along one of the table's long rails , and the player who broke is automatically assigned the three pockets situated along the opposite long rail. Once that selection is made, balls 1–6 may be pocketed in any pocket in rotation, starting with the one, as the object ball. Balls pocketed via combinations off of the object ball are legal. The 7-ball must be pocketed in player's assigned side to be a legal win. Scratches on any object ball allow the opponent ball-in-hand, but the sunk ball remains potted. Scratching on the 7-ball is a loss. Pocketing the 7-ball in any other pocket than one on the called side is a loss. [2]
A special 7-ball was designed for television matches by Charles Ursitti (billiards historian, referee and Willie Mosconi's one time manager) to more easily distinguish the 7-ball from the 3 on television. [1] The ball adopts the stripe of the 9-ball with the color of the solid black 8-ball , the " money balls " of their respective namesake games.
No special equipment is required for play; a regular set of pool balls and a nine-ball diamond rack turned sidewise are adequate.
The original informal incarnation of seven-ball led to a variant professional ruleset that enjoyed a brief heyday in the series Sudden Death Seven-ball, broadcast on the American cable TV network ESPN from 2000 to 2005.
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.
Eight-ball is a discipline of pool played on a billiard table with six pockets, cue sticks, and sixteen billiard balls. The object balls include seven solid-colored balls numbered 1 through 7, seven striped balls numbered 9 through 15, and the black 8 ball. After the balls are scattered with a break shot, a player is assigned either the group of solid or striped balls once they have legally pocketed a ball from that group. The object of the game is to legally pocket the 8-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.
Nine-ball is a discipline of the cue sport pool. The game's origins are traceable to the 1920s in the United States. It is played on a rectangular billiard table with pockets at each of the four corners and in the middle of each long side. Using a cue stick, players must strike the white cue ball to pocket nine colored billiard balls, hitting them in ascending numerical order. An individual game is won by the player pocketing the 9-ball. Matches are usually played as a race to a set number of racks, with the player who reaches the set number winning the match.
Straight pool, which is also called 14.1 continuous and 14.1 rack, is a cue sport in which two competing players attempt to pocket as many object balls as possible without playing a foul. The game was the primary version of pool played in professional competition until it was superseded by faster-playing games like nine-ball and eight-ball in the 1980s.
Golf billiards is a pocket billiards game usually played for money. Unlike the majority of such games, it allows more than two people to play without compromises or rule changes. The game borrows from the outdoor game of golf, which is historically related to the cue sports. It is usually played on 10-foot or 12-foot snooker tables as their size and structure are more appropriate. In 2006 the Billiard Congress of America commented it was more popular than snooker in the United States.
Cutthroat or cut-throat, also sometimes referred to as three-man-screw, is a typically three-player or team pocket billiards game, played on a pool table, with a full standard set of pool balls ; the game cannot be played with three or more players with an unnumbered reds-and-yellows ball set, as used in blackball. Each player is commonly assigned a set of five consecutively numbered object balls, though the number of balls will vary by number of players. The object of the game is to be the last player with at least one ball of their group remaining on the table.
Russian pyramid, also known as Russian billiards ', is a form of billiards played on a large billiard table with narrow pockets. It is popular across Eastern Europe as well as countries of the former Soviet Union/Eastern Bloc. In Western countries, the game is known as pyramid billiards, or simply pyramid.
Pool is a classification of cue sports played on a table with six pockets along the rails, into which balls are shot. Each specific pool game has its own name; some of the better-known 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 is often thought of as synonymous with "pool".
Bank pool is a pool game that has as its most fundamental requirement that all scoring shots in the game must be made by banking a called ball off a cushion and into a called pocket.
A rack is a piece of equipment that is used to place billiard balls in their starting positions at the beginning of a pocket billiards game. Rack may also be used as a verb to describe the act of setting billiard balls in their starting positions, or as a noun to describe a set of balls that are in their starting positions.
The following is a glossary of traditional English-language terms used in the three overarching cue sports disciplines: carom billiards referring to the various carom games played on a billiard table without pockets; pool, which denotes a host of games played on a table with six pockets; and snooker, played on a large pocket table, and which has a sport culture unto itself distinct from pool. There are also games such as English billiards that include aspects of multiple disciplines.
Rotation, sometimes called rotation pool, 15-ball rotation, or 61, is a pool game, played with a pocketed billiards table, cue ball, and triangular rack of fifteen billiard balls, in which the lowest-numbered object ball on the table must be always struck by the cue ball first, to attempt to pocket numbered balls for points.
Three-ball is a folk game of pool played with any three standard pool object balls and cue ball. The game is frequently gambled upon. The goal is to pocket the three object balls in as few shots as possible. The game involves a somewhat more significant amount of luck than either nine-ball or eight-ball, because of the disproportionate value of pocketing balls on the break shot and increased difficulty of doing so. In some areas and subcultures, such as the Asian-American youth-dominated pool hall scene of San Francisco, California, three-ball is a popular local tournament game.
Chicago is a "money ball" pool gambling game.
Cowboy pool is a hybrid pool game combining elements of English billiards through an intermediary game, with more standard pocket billiards characteristics. The game employs four balls, the cue ball and three others, numbered one, three, and five. A game of Cowboy pool is contested as a race to 101 points, with those points being awarded for a host of different shot types. Dating back to 1908, the game is a strictly amateur pastime.
Kelly pool is a pool game played on a standard pool table using a standard set of 16 pool balls. Gameplay involves players each drawing one of 16 numbered markers called peas or pills at random from a shake bottle, which assigns to them the correspondingly numbered pool ball, kept secret from their opponents, but which they must pocket to win the game. Kelly pool is a rotation game, which means that players must contact the lowest numbered object ball on each shot first until the opportunity to pocket their own is presented. If a player draws the number 16, this player is assigned the cue ball. In order to pocket the cue ball, the player must contact the lowest ball first and in the same shot, pocket the cue ball. However, the game is commonly played by removing the pea numbered 16 and playing with the basic 15 numbered balls and corresponding peas. Two rule variants are set forth under rules promulgated by the Billiard Congress of America (BCA). In the simpler form, the object of play starts and ends with the goal of pocketing one's secret ball. In the second, in addition to the goal of pocketing one's secret ball, points are scored in various ways. In the instance where pills are unavailable, a cloth may be used to cover the balls, which are then chosen blindly, recorded, and replaced for play.
Baseball pocket billiards or baseball pool is a pocket billiards (pool) game suitable for multiple players that borrows phraseology and even some aspects of form from the game of baseball. For instance, although baseball pool is played on a standard pool table, the 9 ball is known as the "pitcher", the table's foot spot where balls are racked is known as "home plate", and each team or player is afforded "nine innings]" to score as many "runs" as possible.
Bottle pool, also known as bottle-billiards and bottle pocket billiards, is a hybrid billiards game combining aspects of both carom billiards and pocket billiards. Played on a standard pool table, the game uses just two object balls, a cue ball, and a 6+3⁄4 inches (170 mm) tall, narrow-necked bottle called a shake bottle or tally bottle, traditionally made from leather, that is placed on the table and used as a target for caroms. Those unfamiliar with the game sometimes mistakenly use its name as a synonym for the very different game of kelly pool. Bottle pool has been described as combining "elements of billiards, straight pool and chess under a set of rules that lavishly rewards strategic shot making and punishes mistakes with Sisyphean point reversals."
Cribbage, sometimes called cribbage pool, fifteen points and pair pool, is a two-player pool game that, like its namesake card game, has a scoring system which awards points for pairing groups of balls that total 15. Played on a standard pool table, participants who pocket a ball of a particular number are required to immediately pocket the companion ball that tallies to 15 when added to the prior ball's number. Each pair so pocketed counts as a cribbage; there are seven such pairs, and the 15 ball counts as an eighth by itself after all of the others have been pocketed. The first player to score five cribbages wins the game.
Carom billiards and pool are two types of cue sports or billiards-family games, which as a general class are played with a stick called a cue which is used to strike billiard balls, moving them around a cloth-covered billiard table bounded by rubber cushions attached to the confining rails of the table.
