Definition of 4 pins

Four-ball is a carom billiards game. The game is played on a pocketless table with four balls, usually one light red, one dark red, and two whites (or just two reds and two whites). Each player is assigned one of the white balls as his own cue ball. A point is scored when a shooter caroms on any two other balls. Two points are scored when the player caroms on each of the three other balls.

24 Random Essential Billiards Terms

Any standard pool cue used to shoot the majority of shots in a match.
Also slop shot. A luck shot. Compare fish, fluke and Lorengo; contrast mark and call. Also sloppy. Descriptive of any game where the rules have been varied to allow luck shots not normally allowed or where no foul rules apply.
A slang term for a cue, usually used with "piece", as in "that's a nice piece of wood".
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.
Describing a ball that is safe because it is in close proximity to one or more other balls, and would need to be developed before it becomes pottable.
In one pocket pool this means that you change your play based on where the count is during the game. If you are ahead you might choose more conservative shots, and if you are behind you could choose more aggressive shots.
In snooker, the colour ball worth 5 points, whose spot is at the center of the table.
In snooker, after particular fouls are committed, the referee can call a "free ball." This allows the next player to assign any ball as "ball on" if he or she is shooting next.
Also highs, high balls, high ones. In eight-ball and related games, to be shooting the striped suit (group) of balls (9 through 15); "you're high balls" or "I've got the highs" ("you're high" is rare, because of the "intoxication" ambiguity). Compare stripes, yellows, big ones, overs; contrast low.
A thin sheet of rigid material in the size and shape of a physical ball rack (e.g. a diamond for nine-ball), with holes drilled though it, which is used to make permanent divots in the cloth of the table, one at a time for each ball in the racking pattern, by placing a ball in one of the holes in the carefully placed template and tapping it sharply from above to create the cloth indentation. The holes are spaced slightly closer than the regulation ball width of 21/2 inch (57.15 mm) apart, so that when the balls settle partially into their divots, the outer sides of these indentations create ball-on-ball pressure, pushing the balls together tightly. The purpose of the template is to do away with using a physical rack, with racking instead being performed simply by placing the balls into position, and the divots aligning them into the tightest possible formation automatically. This prevents accidental loose racks, and also thwarts the possibility of cheating by carefully manipulating the ball positions while racking. The European Pocket Billiard Federation (EPBF, Europe's WPA affiliate organization) has adopted this racking technique for its professional Euro-Tour event series.
This is the act of disturbing you opponents good looking balls in the hope that they might move over and help you out in the game of one pocket.
This is when a ball is spotted because of a foul or a handicap.
This is a shot that attempts to move a number of balls onto your side of the table in a kind of herding attempt.
A pejorative term for an improper rack in which the balls are not properly in contact with their neighbors, often resulting in a poor spread on the break.
A tournament format in which a player must lose two matches in order to be eliminated.
A cluster of balls. In snooker, the bunch of reds that are typically left below the pink spot in the early stages of a frame, not including those reds that have been released into pottable positions.
In the eight-ball game variant blackball, also known as eight-ball pool, a differently colored but otherwise identical replacement for the red group (i.e., what would be the solids in an American-style pool ball set).
Any ball that may be legally struck by the cue ball.
Also bar rules, pub pool, tavern pool. Pool, almost always a variant of eight-ball, that is played by bar players on a bar table. Bar pool has rules that vary from region to region, sometimes even from venue to venue in the same city, especially in the U.S. Wise players thus ensure understanding of and agreement to the rules before engaging in a money game under bar rules. Typical differences between bar pool and tournament eight-ball are the lack of ball-in-hand after a foul, the elimination of a number of fouls, and (with numbered ball sets) the requirement that most aspects of a shot be called (including cushions and other object balls to be contacted) not just the target ball and pocket. Bar pool has evolved into this "nitpicky" version principally to make the games last longer, since bar pool is typically played on coin-operated tables that cost money per-game rather than per-hour. Competitive league pool played on bar tables, however, usually uses international, national or local/regional league rules, and is not what is usually meant by "bar pool".
This a shot that hits the object ball at the nine ball to see if you can get lucky by sinking the nine ball in any pocket. (also see Rolling the Cheese and Cheese the Nine).
This is when you strike a cue ball off center to gain control on the movement on the cue ball.
This when you receive the first legitimate shot on the next "ball on" after there had been a series of safeties to try and hurt the other players chances. This term is often used in one pocket pool.
This is the portion of the joint that actually connects the two sides of the cue, often called the pin or male end. This comes in a number of different sizes and shapes which some believe has an influence on the hit of the cue stick.
In eight-ball and related games, describes the situation in which neither player has yet claimed a suit (group) of balls. Often shortened to simply open: "Is it still an open table?" "Yes, it's open."
