Rotation, sometimes called rotation pool or 61, is a pool game, played with a billiards table, , and triangular rack of fifteen billiard balls, in which the lowest-numbered on the table must be always struck by the cue ball first, to attempt to numbered balls for . Some attractions of rotation include performing unconventional or difficult shots to reach the correct ball, and quite often making risky attempts to score higher numbers of points by performing advanced shots such as , , and . Rules Object The object of the game is to score the most points, by pocketing higher-scoring balls than the opponent(s).

Rotation Rack
Rotation, or spin, is the circular movement of an object around a '' central axis''. A two-dimensional rotating object has only one possible central axis and can rotate in either a clockwise or counterclockwise direction. A three-dimensional object has an infinite number of possible central axes and rotational directions. If the rotation axis passes internally through the body's own center of mass, then the body is said to be ''autorotating'' or ''spinning'', and the surface intersection of the axis can be called a ''pole''. A rotation around a completely external axis, e.g. the planet Earth around the Sun, is called ''revolving'' or ''orbiting'', typically when it is produced by gravity, and the ends of the rotation axis can be called the ''orbital poles''. Mathematics Mathematically, a rotation is a rigid body movement which, unlike a translation, keeps a point fixed. This definition applies to rotations within both two and three dimensions (in a plane and in space, r ...

Pool (cue Sports)
Pool is a classification of cue sports played on a table with six pockets along the , into which balls are deposited. "Pool billiards" is sometimes hyphenated and/or spelled with a singular "billiard". The WPA itself uses "pool-billiard" in its logo but "pool-billiards" in its legal notices. The organization compounds the words to result in an acronym of "WPA", "WPBA" having already been taken by the Women's Professional Billiards Association. Normal English grammar would not hyphenate here, and the term is actually a Germanism. A general rules booklet on pool games in general, including eight-ball, nine-ball and several others. 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. The generic term pocket billiards is sometimes also used, and favored by some pool-industry bodies, but is technically a broader classification, including games such as snooke ...

Billiards Table
A billiard table or billiards table is a bounded table (furniture), table on which cue sports are played.

More specific terms are used for specific sports, such as snooker table and pool table, and different-sized billiard balls are used on these table types. An obsolete term is billiard board, used in the 16th and 17th centuries. Parts and equipment Cushions Cushions (also sometimes called "rail cushions", "cushion rubber", or rarely "bumpers") are located on the inner sides of a table's wooden .

Rack (billiards)
A rack (sometimes called a triangle) 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 (e.g. "to rack the balls"), or as a noun to describe a set of balls that are in their starting positions (e.g. "a rack of balls", more often called a ''pack'' or a ''pyramid'' in British English). Traditional racks are in the form of triangular frames, usually made from wood, plastic or metal. A modern variation, called a ''template rack'', is made from a thin material (usually 0.14 mm or less) that contains precision cut-outs to hold the balls in place. Purported benefits of template racks include a more consistent racking, and their popularity has warranted specific inclusion in profession rules. Unlike traditional racks, template racks are left on the table during the break shot and removed at the ...

Billiard Balls
A billiard ball is a small, hard ball used in cue sports, such as carom billiards, pool, and snooker. The number, type, diameter, color, and pattern of the balls differ depending upon the specific game being played. Various particular ball properties such as hardness, friction coefficient, and resilience are important to accuracy. History Early balls were made of various materials, including wood and clay (the latter remaining in use well into the 20th century). Although affordable ox-bone balls were in common use in Europe, elephant ivory was favored since at least 1627 until the early 20th century; the earliest known written reference to ivory billiard balls is in the 1588 inventory of the Duke of Norfolk. Dyed and numbered balls appeared around the early 1770s. By the mid-19th century, elephants were being slaughtered for their ivory at an alarming rate, just to keep up with the demand for high-end billiard balls – no more than eight balls could be made from a single e ...

Eight-ball
Eight-ball (also spelled 8-ball or eightball, and sometimes called solids and stripes, spots and stripes or rarely highs and lows) is a discipline of pool played on a billiard table with six pockets, cue sticks, and sixteen billiard balls (a and fifteen ). 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 , 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. The game is the most frequently played discipline of pool, and is often thought of as synonymous with "pool". The game has numerous variations, mostly regional. It is the second most played professional pool game, after nine-ball, and for the last ...

Kelly Pool
Kelly pool (also known as pea pool, pill pool, keeley, the keilley game, and killy) 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 15 numbered markers called peas or pills at random from a , 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 game, which means that players must contact the lowest numbered on each shot first until the opportunity to pocket their own is presented. 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, ...

Pyramid Pool
Pyramid pool, or simply pyramids, is a form of pool that was played mainly in the 19th century. It was one of several pool games that were popular at this time, and was forerunner to modern games such as eight-ball, blackball, straight pool, and Russian pyramid. Along with black pool, it was one of the progenitor cue sports of snooker. Rules were racked in a triangle with any remaining balls placed at the back of the triangle. It could be played by several players, with an agreed stake per ball pocketed, or with just two players in which case the winner is the one to first sink over half the balls. Teams were also allowed if there were an even number of players. In early versions of the game, when one object ball remained, the game shifted so one player took possession of the original cue ball, while the other used the object ball, as they attempted to sink the other player's designated ball. This rule was dropped in the United States during the late 19th century. An early ver ...
