1 TABLES, BALLS, EQUIPMENT
All games described in these rules are designed for tables, balls and equipment meeting the standards prescribed in the WPA Equipment Specifications.
2 RACKING THE BALLS
When racking the balls a triangle must be used, and the apex ball is to be spotted on the foot spot. All the balls must be lined up behind the apex ball and pressed together so that they all have contact with each other.
3 STRIKING CUE BALL
Legal shots require that the cue ball be struck only with the cue tip. Failure to meet this requirement is a foul.
4 CALLING SHOTS
For games of call-shot a player may shoot any ball he chooses, but before he shoots, must designate the called ball and called pocket. He need not indicate any detail such as kisses, caroms, combinations, or cushions (all of which are legal). Any additionally pocketed ball(s) on a legal stroke is counted in the shooter’s favor.
5 FAILURE TO POCKET A BALL
If a player fails to pocket a ball on a legal shot, then the player’s inning is over, and it is the opponent’s turn at the table.
6 LAG FOR BREAK
The following procedure is used for the lag for the opening break. Each player should use balls of equal size and weight (preferably cue balls but, when not available, non-striped object balls). With the balls in hand behind the head string, one player to the left and one to the right of the head spot, the balls are shot simultaneously to the foot cushion and back to the head end of the table. The player whose ball is the closest to the innermost edge of the head cushion wins the lag. The lagged ball must contact the foot cushion at least once. Other cushion contacts are immaterial, except as prohibited below. It is an automatic loss of the lag if:
(a) The ball crosses into the opponent’s half of the table;
(b) The ball fails to contact the foot cushion;
(c) The ball drops into a pocket;
(d) The ball jumps the table;
(e) The ball touches the long cushion;
(f) The ball rests within the corner pocket and past the nose of the head cushion, or;
(g) The ball contacts the foot rail more than once. If both players violate automatic-loss lag rules, or if the referee is unable to determine which ball is closer, the lag is a tie and is replayed.
7 OPENING BREAK SHOT
The opening break shot is determined by either lag or lot. (The lag for break procedure is required for formal competition.) The player winning the lag or lot has the choice of performing the opening break shot or assigning it to the opponent.
8 CUE BALL ON OPENING BREAK
The opening break shot is taken with cue ball in hand behind the head string. The object balls are positioned according to specific game rules. On the opening break, the game is considered to have commenced once the cue ball has been struck by the cue tip.
On the break shot, stopping or deflecting the cue ball after it has crossed the head string and prior to hitting the racked balls is considered a foul and loss of turn. The opponent has the option of receiving cue ball in hand behind the head string or passing the cue ball in hand behind the head string back to the offending player. A warning must be given that a second violation during the match will result in the loss of the match by forfeiture.
10 CUE BALL IN HAND BEHIND THE HEAD STRING
This situation applies in specific games whereby the opening break is administered or a player’s scratching is penalized by the incoming player having cue ball in hand behind the head string. The incoming player may place the cue ball anywhere behind the head string. The shooting player may shoot at any object ball as long as the base of the object ball is on or below the head string. He may not shoot at any ball, the base of which is above the head string, unless he first shoots the cue ball below the head string and then by hitting a rail causes the cue ball to come back above the head string and hit the object ball. The base of the ball (the point of the ball touching the table) determines whether it is above or below the head string. If the incoming player inadvertently places the cue ball on or below the head string, the referee or the opposing player must inform the shooting player of improper positioning of the cue ball before the shot is made. If the opposing player does not so inform the shooting player before the shot is made, the shot is considered legal. If the shooting player is informed of improper positioning, he must then reposition the cue ball. If a player positions the cue ball completely and obviously outside the kitchen and shoots the cue ball, it is a foul. When the cue ball is in hand behind the head string, it remains in hand (not in play) until the player drives the cue ball past the head string by striking it with his cue tip. The cue ball may be adjusted by the player’s hand, cue, etc., so long as it remains in hand. Once the cue ball is in play per the above, it may not be impeded in any way by the player; to do so is to commit a foul. Additionally, if the shot fails to contact a legal object ball or fails to drive the cue ball over the head string, the shot is a foul and the opposing player has ball in hand according to the specific game rules.
11 POCKETED BALLS
A ball is considered pocketed if as a result of an otherwise legal shot, it drops off the bed of the table into the pocket and remains there. (A ball that drops out of a ball return system onto the floor is not to be construed as a ball that has not remained pocketed.) A ball that re-bounds from a pocket back onto the table bed is not a pocketed ball.
12 POSITION OF BALLS
The position of a ball is judged by where its base (or center) rests.
13 FOOT ON FLOOR
Player must have at least one foot in contact with the floor at the moment the cue tip contacts the cue ball, or the shot is a foul. Foot attire must be normal in regard to size, shape and manner in which it is worn.
14 SHOOTING WITH BALLS IN MOTION
It is a foul if a player shoots while the cue ball or any object ball is in motion (a spinning ball is in motion).
15 COMPLETION OF STROKE
A stroke is not complete (and therefore is not counted) until all balls on the table have become motionless after the stroke (a spinning ball is in motion).
16 HEAD STRING DEFINED
The area behind the head string does not include the head string. Thus, an object ball that is dead center on the head string is playable when specific game rules require that a player must shoot at a ball past the head string. Likewise, the cue ball when being put in play behind the head string (cue ball in hand behind the head string), may not be placed directly on the head string; it must be behind it.
17 GENERAL RULE, ALL FOULS
Though the penalties for fouls differ from game to game, the following apply to all fouls:
(a) Player’s inning ends;
(b) If on a stroke, the stroke is invalid and any pocketed balls are not counted to the shooter’s credit, and;
(c) Any ball(s) is respotted only if the rules of the specific game require it.
18 FAILURE TO CONTACT OBJECT BALL
It is a foul if on a stroke the cue ball fails to make contact with any legal object ball first. Playing away from a touching ball does not constitute having hit that ball.
Unless otherwise stated in a specific game rule, a player must cause the cue ball to contact a legal object ball and then:
(a) Pocket a numbered ball, or;
(b) Cause the cue ball or any numbered ball to contact a cushion or any part of the rail. Failure to meet these requirements is a foul.
20 CUE BALL SCRATCH
It is a foul (scratch) if on a stroke, the cue ball is pocketed. If the cue ball touches an object ball that was already pocketed (for example, in a pocket full of object balls), the shot is a foul.
21 FOULS BY TOUCHING BALLS
It is a foul to strike, touch or in any way make contact with the cue ball in play or any object balls in play with anything (the body, clothing, chalk, mechanical bridge, cue shaft, etc.) except the cue tip (while attached to the cue shaft), which may contact the cue ball in the execution of a legal shot. Whenever a referee is presiding over a match, any object ball moved during a standard foul must be returned as closely as possible to its original position as judged by the referee, and the incoming player does not have the option of restoration.
22 FOUL BY PLACEMENT
Touching any object ball with the cue ball while it is in hand is a foul.
23 FOULS BY DOUBLE HITS
If the cue ball is touching the required object ball prior to the shot, the player may shoot toward it, providing that any normal stroke is employed. If the cue stick strikes the cue ball more than once on a shot, or if the cue stick is in contact with the cue ball when or after the cue ball contacts an object ball, the shot is foul. If a third ball is close by, care should be taken not to foul that ball under the first part of this rule.
24 PUSH SHOT FOULS
It is a foul if the cue ball is pushed by the cue tip, with contact being maintained for more than the momentary time commensurate with a stroked shot. (Such shots are usually referred to as push shots.)
25 PLAYER RESPONSIBILITY FOULS
The player is responsible for chalk, bridges, files and any other items or equipment he brings to, uses at, or causes to approximate the table. If he drops a piece of chalk, or knocks off a mechanical bridge head, as examples, he is guilty of a foul should such an object make contact with any ball in play (or the cue ball only if no referee is presiding over the match).
26 ILLEGAL JUMPING OF BALL
It is a foul if a player strikes the cue ball below center (“digs under” it) and intentionally causes it to rise off the bed of the table in an effort to clear an obstructing ball. Such jumping action may occasionally occur accidentally, and such “jumps” are not to be considered fouls on their face; they may still be ruled foul strokes, if for example, the ferrule or cue shaft makes contact with the cue ball in the course of the shot.
