Definition of Napl

Name for the ball that when pocketed, wins the game, or any ball that when made results in a payday such as a way in the game of Chicago.

This is a style of play where the player is required to stay on top of all the scoring practices. Scratches and points will disappear if they are not remembered.

To indicate where something is to be done. To "mark the pocket" means to indicate which pocket you intend to sink an object ball.

Failure to hit an object ball at all with the cue ball. In most sets of rules, this is a foul like any other. However, in some variants of bar pool a table scratch while shooting for the 8 ball is a loss of game where other more minor fouls might not be, as is scratching on the 8 ball (neither result in a loss of game in most professional rules).
By way of drift from the above definition, the term is also applied by many league players to the foul in more standardized rules of failing to drive a (any) ball to a cushion, or to pocket a legal object ball, after the cue ball's initial contact with an object ball.
By way of entirely different derivation ("scratch off the table"), it can also mean knocking the cue ball (or more loosely, any ball) completely off the table.

A pool table where two shims have been placed on the sides of each pocket (in the jaws beneath the cloth), making the pockets "tighter" (smaller). Such tables are "tougher" than unshimmed or single-shimmed tables.

The person who is a provider of all or part of a player's stake (money) for a gambling session in which one is not a player.

The World Professional Billiards and Snooker Association, founded in 1968 and based in Bristol, England, United Kingdom is the governing body of professional snooker and English billiards. It sets the sports' rules, organises tournaments and the pro-am and pro tours, and engages in various promotional activities.

This is your pocket for sinking balls in a one pocket game.

This is a very easy and safe shot to execute in the game of one pocket.

Two or more object balls that are touching or are close together.

This is when, after playing an opponent for a while you both break even as far as money exchange, and the only person to get paid is the house for use of their table.

The World Pool-Billiard Association (WPA) is the international governing body for pocket billiards (and also sactions rules and events for carom billiards games as well, in cooperation with other bodies). The group was formed in 1987, and was initially headed by a provisional board of directors consisting of representatives from the United States, Japan, Sweden, and Germany.

A type of nurse shot used in English billiards in which two coloured balls are positioned on either side of the mouth of a snooker table pocket but not touching and, thus placed, can be successively contacted and scored off over and over by the cue ball without moving them.

This piece of armament keeps the butt of your cue safe from coincidental contact with the floor or other damaging incidents. It is usually made of a rubber composite or other durable or flexible material to absorb impact in the case of a collision.

A shot aimed so that the center of the cue ball is in line with the edge of the object ball, eclipsing half of the ball. "Hit it just a little thinner than half-ball." Assuming a cling does not occur, the shot will impart post-contact momentum on the object ball in a direction 30° (which is arcsin(1 - x), where x is the fraction of object ball eclipsed: ½ in this case) off the direction of the cue-ball's pre-contact momentum. Also notable because the carom angle the cue ball takes is more consistent than at other contact points.

A pool ball that was meant to go into the pocket, but got caught up by the jaw and ended up bouncing back and forth before stopping short of the pocket.

This is to lay down the money on the table in a betting game before play begins to ensure pay up at the end.

A joint type in which the butt and shaft screw together in a tight lock, resulting in a better shot with more hitting power.

The Union Mondiale de Billard (French for World Union of Billiards) is the world governing body for carom (carambole) billiard games. The organization was founded in Madrid, Spain on 1 June 1959, and is dedicated to promoting the modern carom billiards games. The UMB monitors and controls international carom competitions and tournaments, and organizes an annual World Three-cushion Billiards Championship.

When you have completed a shot by pocketing a ball into a pocket.

This is what happens when a player sends the cue ball into a cluster of balls that will in turn spread out in an unpredictable fashion.

This is when you win a game of one pocket on your opponents break.

An outgrowth of the training template concept, a racking template is a racking tool used in place of a traditional rigid ball rack for pool or snooker balls, consisting of a very thin, e.g. 0.14 mm (0.0055 in), sheet of material such as paper or plastic with holes into which object balls settle snugly against one another to form a tight rack (pack). The template is placed, stencil-like, in racking position, with the lead ball's hole directly over the center of the foot spot. The balls are then placed onto the template and arranged to settle into their holes, forming a tight rack. Unlike with a training template, the balls are not tapped to create divots, and instead the template is left in place until after the break shot at which time it can be removed (unless balls are still sitting on top of it). Manufacturers such as Magic Ball Rack insist that racking templates are designed "to affect the balls to a minimum", and while pro player Mike Immonen has endorsed that particular brand as a retail product, as of September 2010, no professional tours nor amateur leagues have adopted that or any other racking template. Although Magic Ball Rack implies development work since 2006, other evidence suggests invention, by Magic Ball Rack's founder, in mid 2009, with product announcement taking place in September of that year.

In snooker and British pool, the successful potting of all object balls-on in a single frame.
