Official BCA One Pocket Rules Page 2
6.4 Continued Typically, any owed scratches are indicated by placement of a small coin on the rail top adjacent to the offending player's pocket. An additional coin is placed to represent each additional scratch without a scored ball to spot. One coin is removed for each owed ball repaid by spotting at the end of the first inning or innings in which they are scored, until all owed scratches have been repaid, and standard scoring can commence.
6.5 Driving either the cue ball or an object ball off the table is a foul, whenever either comes to rest off the playing surface, or comes in contact with anything other than the table itself while airborne. Please note that One Pocket has been traditionally played in many areas without a foul charged for jumping an object ball off the table, contrary to current general pocket billiards rules; therefore it is important to verify house rules or your tournament director's interpretation prior to an important match.
6.6 Intentional fouls are an accepted part of One Pocket tactics as long as they are played by use of a legal stroke, such as by lightly touching the cue ball with the cue tip; by rolling the cue ball to a new location without regard for legal contact with either an object ball or a cushion; by pocket scratching the cue ball; or by using a legal jump technique to force the cue ball off the table. However, if the acting official rules that a player has used an illegal technique to direct the cue ball or any object balls to a more desirable location, then the incoming player has the option of either playing the balls where they lie, or requesting the official to restore all such moved balls to their location prior to the illegal maneuver. The offending player is charged the standard one ball foul penalty, and in addition may be further penalized at the discretion of the acting official under the general rules of unsportsmanlike conduct.
6.7 It shall not be a foul to accidentally touch the cue ball while removing an object ball from an adjacent pocket, or when spotting a ball where the cue ball interferes. It shall be a foul for the incoming shooter to accidentally touch an object ball with the cue ball while placing it in a ball in hand situation.
7. Three fouls in a row Three consecutive fouls is loss of game, however the opponent or tournament referee must notify the player that is on two fouls, prior to their third foul. Should no notice occur until after the shot resulting in the third foul is in motion, it is not immediate loss of game, but the player will be considered to be on two fouls for their next shot.The three fouls rule is often waived in after hours situations by agreement between the players.
8. Frozen balls For a foul to result from failure to legally strike a rail after contacting a frozen ball, the ball in question must be inspected and designated as frozen prior to a player's shot, otherwise the ball is not considered frozen. If the cue ball becomes wedged between an object ball and the cushion and frozen to both, then legal shot requirements must be met by pocketing the frozen ball, or by contacting either another ball or another cushion enroute to a legal shot. Failure to do so is a foul.
9. Spotting balls 9.1 Balls are to be spotted on the foot spot, or in a direct line below the foot spot, and tightly frozen to other object balls that fall in or interfere with that line. However if the cue ball interferes, the spotted ball is to be placed on that line close to, but not quite frozen to the cue ball. In the event that the line below the foot spot is full and the bottom rail interferes with a spotted ball then balls are to be spotted on the same line, but above the foot spot.
9.2 Any penalty balls owed by the shooter, or balls pocketed in a neutral pocket, are to be spotted at the end of the shooter's inning. However, if a player runs off all the balls on the table without reaching a winning score, then all such balls are spotted immediately (all at once, not one ball at a time), and the shooter continues their inning. At no other time in One Pocket are balls spotted during any shooter's ongoing inning.
9.3 In the event of a handicapped game with the combined winning ball count needed by the two players or teams totals greater than sixteen at the start of the game, then the player going to the longer count must spot the first ball or balls they score, immediately at the end of the first inning in which they score, as necessary to bring the combined winning ball count back down to sixteen, at which point the game continues in standard fashion.
9.4 If any owed balls, or balls that have fallen into a neutral pocket are forgotten and later remembered, then instead of being spotted after the current shooter's inning, they are spotted after the end of the next player's inning, unless there are no balls left on the table, in which case they are all spotted immediately. In any case, any owed balls are not forgiven, but still must be paid. In practice, forgotten balls may be spotted at any time after they are remembered, as long as both players agree on the timing; if either player objects to an earlier spotting, then rule 9.4 should be followed.
Please note that playing 'snooze you lose' is the rare exception in house rules; it is by no means the standard rule, and it should only be accepted when it is clearly and mutually agreed on by both players before play begins.
9.5 In the event of a scratch with the offending player having no balls to spot when all of the balls are located behind the head string, the ball nearest the head string may be spotted at the request of the incoming player. If two or more balls are equally close to the head string, the highest numbered ball would be spotted.
10. Keeping score10.1 It is the responsibility of the shooting player to verify their own ball count as they approach their out ball, and the non-shooting player should avoid making comments about how many balls are needed. However, if the non-shooting player disturbs the balls, or breaks down their stick, or in the judgment of the acting official otherwise significantly disturbs the shooter in the assumption that the shooter is already out, such acts are considered a concession, and the shooter is considered to have won, regardless of whether a subsequent count reveals that more balls are needed. Likewise, if it can be verified that the non-shooting player's mistaken statement of the number of balls needed leads directly to the shooter pocketingsaid number of balls and the assumption of the game being over, then the shooter wins, even if it is subsequently determined that the non-shooting player's statement of balls needed was in error.
10.2 If the shooting player disturbs only one of the remaining balls on the table under their own mistaken assumption that the game is over, play continues under the terms of rule 6.1. However, if the shooting player disturbs two or more of the remaining balls in play on their own mistaken assumption that the game is over, then it is the shooting player that forfeits the game.Players should refrain from moving or removing balls from their opponent's pocket or scoring tray for any reason, except to spot a ball following a scratch or to sufficiently clear a pocket to permit entry of additional balls for an impending shot, and should only do so with respect for their opponent's scoring preferences.
