Definition of Wild ball

Any shot in which the cue ball or an object ball has to squeeze by (just miss with almost no margin for error) another ball or balls in order to reach its intended target.

A tournament format in which a player is out of the tournament after a single match loss.

Successive games won without the opponent getting to the table; a five-pack would be a package of five games.

This is to take all the money from a player or to have lost all of your own money.

A chiefly British term for a set of mechanical bridges. British-style rests differ from most American-style rake bridges in shape, and take several forms: the cross, the spider and the swan (or goose neck), as well as the rarer and often unsanctioned hook. When used unqualified, the word usually refers to the cross. Rests are used in snooker, English billiards, and blackball.

Chiefly American: Also known as side spin, english (which is usually not capitalized) is spin placed on the cue ball when hit with the cue tip to the left or right of the ball's center. English has a marked effect on cue ball rebound angle off cushions (though not off object balls), and is thus crucial for gaining shape; and can be used to "throw" an object ball slightly off its otherwise expected trajectory, to cheat the pocket, and for other effects. "English" is sometimes used more inclusively, to colloquially also refer to follow and draw. In combination one could say bottom-right english, or like the face of a clock (4 o'clock english). The British and Irish do not use this term, instead preferring "side".

The material which covers the bed and cushions of a pool table. The cloth used to cover a pool table is very special and can come in a variety of grades. Along with the general quality of the table itself, the cloth play a very important role in how a particular table plays.

The effect of shooting regulation-weight object balls with an old-fashioned over-weight bar table cue ball, such that the cue ball moves forward to occupy (sometimes only temporarily), or go beyond, the original position of the object ball, even on a draw or stop shot, because the mass of the cue ball exceeds that of the object ball. Players who understand smash-through well can use it intentionally for position play, such as to nudge other object balls nearby the target ball. Smash-through also makes it dangerous in bar pool (when equipped with such a cue ball) to pocket straight-on ducks with a stop shot instead of by cheating the pocket because of the likelihood of scratching the cue ball.

A shot in which the cue ball is struck above its equator with sufficient top spin to cause the cue ball to travel forward after it contacts an object ball. When a cue ball with follow on it contacts an object ball squarely (a center-to-center hit), the cue ball travels directly forward through the space previously occupied by the object ball (and can sometimes even be used to pocket a second ball). By contrast, on a cut shot, a cue ball with follow on it will first travel on the tangent line after striking the object ball, and then arc forward, widening the carom angle.

In a tournament, to place high enough to receive a payout. E.g., in a tournament that pays from 1st down to 5th places, to be at least 5th place is to be in the money.

This is the white ball in carom games which is separated from the clear ball by a marking (usually a dot or spot).

This is a term used in slang to reference the bridge tool.

Side spin on the cue ball that causes it to unnaturally roll off a cushion (contacted at an angle) against rather than with the ball's momentum and direction of travel. If angling into a cushion that is on the right, then reverse english would be right english, and vice versa. The angle of deflection will be steeper (narrower) than if no english were applied. The opposite of running english, which has effects other than simply the opposites of those of reverse english.

In three cushion billiards, the most standard shot where the third ball is advantageously placed in a corner.

Describing a pot played at such a pace as to just reach the pocket and drop in without hitting the back.

During a set if the opponent does not win a single game, they are said to have been skunked.

A tournament format in which each contestant plays each of the other contestants at least once. In typical league team play, round robin format means that each member of the home team plays each member of the visiting team once. This format is used by BCAPL, VNEA and many other leagues.

Play, from the opening break shot until one player has won (or the game has been halted for some reason by a referee). Games are the units that make up matches, races (in some senses of that term) and rounds. Essentially the same as frame, except with regards to straight pool, which is a multi-rack game.

This is an imaginary player that you can attempt to run a rack against when playing a practice or training game.

Used with an amount to signify money added to a tournament prize fund in addition to the amount accumulated from entry fees (e.g. "$500 added").

This refers to the distance of deflection that the ball comes off of the cue stick after a hit is applied with side spin on it.
