Section 2. Definitions

1. Game

A game is the period of play from the opening stroke until it is completed by

reaching the end of a specified period of time,
either side reaching the number of points specified, or
being awarded by the referee under Section 4 Rule 2.

2. Match

A match is an agreed or stipulated number of games.

3. Balls

The cue-ball is the ball of the striker
The other white ball and the red are object balls.

4. Stringing

Stringing is when both players (or one from each side) play together from the Baulk-line on either side of the "D" to the top cushion, with the object of leaving the ball played closer to the bottom cushion that the ball played by the opponent.

5. Striker

The person about to play or in play is the striker and remains so until the referee has decided he has left the table at the end of his turn.

6. Stroke

A stroke is made when the striker strikes the cue-ball with the tip of the cue.
A stroke is fair when no infringement of Rule is made.
A stroke is not completed until all balls have come to rest.
A stroke may be made directly or indirectly, thus:
- a stroke is direct when the cue-ball strikes an object ball without first striking a cushion
- a stroke is indirect when the cue-ball strikes one or more cushions before striking the first, or second object ball.

7. Pot

A pot is when an object ball, after contact with another ball and without any infringement of these Rules, enters a pocket. Causing a ball to be potted is known as potting. A pot is also known as a winning hazard.

8. In-off

An in-off is when the cue-ball, after contacting an object ball and without any infringement of these Rules, enters a pocket. If both object balls are contacted by the cue-ball, it is held to have gone in-off the first object ball contacted. An in-off is also known as a losing hazard.

a pot,
an in-off,
two pots,
a pot and an in-off, or

It remains in-hand until
- it is played fairly from in-hand,
- a foul is committed whilst the ball is on the table, or
- it is spotted under Section 3 Rules 10(c)or 15(c) (ii).
The striker is said to be in-hand when the cue-ball is in-hand as above.

A player's ball is in play when it is not in-hand.
The red is in play when spotted and remains so until pocketed or forced off the table.

14. Ball in Baulk

A ball is in Baulk when it rests on the Baulk-line or between that line and the bottom cushion.

15. Forced off the table

A ball is forced off the table if it comes to rest other than on the bed of the table or in a pocket, or if it is picked up by the striker whilst it is in play.

17. Running a coup

The striker when in hand directly pockets his cue ball when no ball(s) are in play.

20. Push Stroke

A push stroke is made when the tip of the cue remains in contact with the cue-ball

after the cue-ball has commenced its forward motion, or
as the cue-ball makes contact with an object ball except, where the cue-ball and an object ball are almost touching, it shall not be deemed a push stroke if the cue-ball hits a very fine edge of the object ball.

21. Jump shot

A jump shot is made when the cue-ball passes over any part of an object ball, whether touching it in the process or not, except:

when the cue-ball first strikes one object ball and then jumps over the other ball.
when the cue-ball jumps and strikes an object ball, but does not land on the far side of that ball.
When, after striking a ball lawfully, the cue-ball jumps over that ball after hitting a cushion or another ball.

Section 3. The Game

1. Description

English Billiards is played by two persons or sides and the game can be summarised as follows:

Three balls are used: a plain white by one side, a spot white (with two or more black spots for identification) by the other side, and a red.
Scoring strokes in a player's turn are made by pots, in-offs and cannons singly or in combination.
Points awarded for scoring strokes are added to the score of the striker.
Penalty points from fouls and misses are added to the opponent's score.
A tactic employed at any time during a game is to leave both object balls in Baulk when the next player is in-hand such that any attempt at disturbing the balls must be by means of an indirect stroke.
The winner of a game is the player or side
- who has scored most points in the agreed or stipulated time,
- who first reaches the agreed or stipulated number of points,
- to whom the game is awarded under Section 4 Rule 2, or
- to whom the game is conceded.
The winner of a match is the player or side winning most games or, where aggregate points are relevant, with the greatest total.

2. Start of Game

The choice of white ball and which side is to play first shall be decided by stringing or any mutually agreed manner, the winner having both options unless all players mutually agree on these options.

The order of play thus determined must remain unaltered throughout the game.
The red is placed on the Spot and the first player plays from in-hand, the game commencing when the cue-ball has been placed on the table and contacted with the tip of the cue, either
- as a stroke is made, or
- while addressing the cue-ball
If the wrong white ball is used for the opening stroke, that stroke is void and the game must be started with the correct ball. Once the game has started, it is the responsibility of the striker to ensure that he plays with the correct white ball even if the wrong white ball is passed to him by the referee.

3. Mode of Play

The players play alternately, or in turn, unless a score is made, in which case the striker continues the break playing from the position left or, after an in-off or if touching another ball as provided for in Section 3 Rule13, from in-hand. When the striker fails to score, his turn ends and the next player plays from the position then left, this being from in-hand if his cue-ball is off the table or touching another ball as provided for in Section 3 Rule 13. After a foul the next player has the additional option of playing from in-hand with both object balls spotted as provided for in Section 3 Rule 15 (c) (ii).

4. Scoring

Points are awarded as follows:

A cannon, pot white and in-off white shall each score two.
A pot red and an in-off red shall each score three.
If more than one hazard or a combination of hazard/s and cannon are made in the same stroke, all are scored.
When an in-off is combined with a cannon, the in-off shall score (additionally to the cannon)
- three points if the red was struck first by the cue-ball,
- two points if the object white was struck first, or
- two points if both object balls were struck simultaneously.

5. End of Session and Game

At the end of the period of time set for any session, the referee shall call TIME. Any stroke that has been made shall be allowed to finish and any points scored shall be added to the appropriate side. If other sessions are to follow, the position of all balls shall be measured and noted by the referee so that the next session may commence from the point of interruption.
The end of the final session as above is the end of a game in a time format.
In a game or match played to a time limit, it is possible that the scores could be level at the end of the period of time allowed and the rules setting the period of time should include any provision for any necessary tie-break.
When playing to an agreed or stipulated number of points, the end of the game is reached when a player first reaches or passes the required number. Only the points required are counted, though the player shall be credited with a break that includes all points scored.

6. Playing from In-hand

To play from in-hand, the cue-ball must be struck from a position on or within the lines of the "D", and

the referee will state, if asked, whether the cue-ball is properly placed (that is, not outside the lines of the "D").
if the tip of the cue should touch the cue-ball while positioning it, and the referee is satisfied that the striker was not attempting to play a stroke, then the cue-ball is not in play.
The cue-ball must be played out of Baulk. If it contacts an object ball then it is out of Baulk, the cue-ball is held to have been played out of Baulk even though it may not physically cross the Baulk-line. (d) The cue-ball must contact a cushion or ball out of Baulk before re-entering and coming to rest in Baulk, or before hitting a ball in Baulk.
The cue-ball may be played against a cushion in Baulk before hitting a ball out of Baulk.
If an object ball is in Baulk, no part of its surface may be played on directly from in-hand, even if that part of its surface is above the Baulk-line.

7. Ball on Baulk-line

The referee shall state, if asked, whether a ball on or near the Baulk-line is in Baulk or out of Baulk.

8. Spotting Object Balls

If the red is pocketed or forced off the table, it is placed on the Spot, or
- if the Spot is occupied, it shall be placed on the Pyramid Spot
- if both the Spot and the Pyramid Spot are occupied, it shall be placed on the Centre Spot.
If the red is potted twice in succession in one break from the Spot or from the Pyramid Spot, not in conjunction with another score, it shall be placed on the Centre Spot, or
- if the Centre Spot is occupied, it shall be placed on the Pyramid Spot.
- if both the Centre Spot and the Pyramid Spot are occupied, it shall be placed on the Spot.
For continued pots of the red, not in conjunction with another score, it shall be placed on the Spot twice, then the Centre Spot once, in sequence while those spots are not occupied.
The referee shall inform the striker upon request how many consecutive pots have been made off the same spot.
A ball is not considered to be on any spot unless it was placed there by hand.
If another ball should touch any ball that has been placed by hand on a spot, that ball is no longer considered to be on that spot, even though it may not have moved.
A player shall not be held responsible for any mistake by the referee in failing to spot correctly any object ball.

9. Limitation of Cannons

Consecutive cannons, not in conjunction with a hazard, are limited to seventy-five.

After seventy such cannons, the referee shall state SEVENTY CANNONS. If the referee should fail to announce when seventy cannons have been made, the striker shall be entitled to make five more such cannons after the referee does announce SEVENTY CANNONS.
The referee shall inform the striker upon request how many consecutive strokes of cannons have been made.

10. Limitation of Hazards

Consecutive hazards, not in conjunction with a cannon, are limited to fifteen strokes.

After ten such strokes of hazards, the referee shall state TEN HAZARDS. If the referee should fail to announce when ten hazards have been made, the striker shall be entitled to make five more such hazards after the referee does announce TEN HAZARDS.
The referee shall inform the striker upon request how many consecutive strokes of hazards have been made.
If the non-striker's ball is off the table as a result of the non-striker's last stroke, it shall be placed on the Middle of the Baulk-line after the fifteenth hazard or, if that is occupied, on the right-hand corner of the "D", viewed from the bottom end of the table.

11. Ball on Edge of Pocket

If a ball falls into a pocket without being hit by another ball, and being no part of any stroke in progress, it shall be replaced and any points scored shall count.
If it would have been hit by any ball involved in a stroke:
- with no infringement of these Rules, all balls will be replaced and the same stroke played again, or a different stroke may be played at his discretion, by the same striker.
- if a foul is committed all balls will be replaced and the next player has the usual options after a foul.
If a ball balances momentarily on the edge of a pocket and then falls in, it shall count as in the pocket and not be replaced.

12. Ball Moved by Other than Striker

If a ball, stationary or moving, is disturbed other than by the striker, it shall be re-positioned by the referee to the place he judges the ball was, or would have finished.

This Rule shall include cases where another occurrence or person, other than the striker's partner, causes the striker to move a ball.
No player shall be penalised for any disturbance of balls by the referee.

13. Touching Ball

When the striker's ball remains touching another ball, red shall be placed on the Spot, the non-striker's ball, if on the table, shall be placed on the Centre Spot, and the striker shall play from in-hand.

All points scored in a break before a foul is awarded are allowed but the striker shall not score any points in a stroke called foul.
All fouls will incur a penalty of two points but not more than two points shall be forfeited in any one stroke. Additionally, the next player shall have the option of playing
- from where the balls have come to rest, the red if not correctly spotted remaining where positioned except that if off the table it shall be correctly spotted, or
- from in-hand with the red placed on the Spot and the object white placed on the Centre Spot.
If the foul is neither awarded by the referee, nor successfully claimed by the non-striker before the next stroke is made, it is condoned.

16. Action after a Miss

If a miss is made, by other than a stroke made directly into a pocket or off a shoulder of a pocket when the striker is in-hand with no object ball out of Baulk, the referee shall call MISS. A penalty of two points is incurred, which is added to the opponent's score. Any other miss is a foul, and all direct 'coups' are fouls.

17. Four-handed Billiards

The side to make the first stroke is decided by the winner of the stringing, as per Section 3 Rule 2. The order of play is then determined by the next player after which the order must remain unchanged throughout the game.
Partners may confer during a game but not
- whilst one is the striker and at the table, nor
- after the first stroke of the striker's turn until the break ends.

18. Use of Ancillary Equipment

It is the responsibility if the striker to both place and remove any equipment he may use at the table.

The striker is responsible for all items including, but not limited to, rests and extensions that he brings to the table, whether owned by him or borrowed (except from the referee), and he will be penalised for any fouls made by him when using this equipment.
Equipment normally found at the table which has been provided by another party including the referee are not responsibility of the striker. Should this equipment prove to be faulty and thereby cause the striker to touch a ball or balls, no foul will be called. The referee will, if necessary, reposition any balls in accordance with Rule 12 above and the striker, if in a break, will be allowed to continue without penalty.

19. Interpretation

Throughout these Rules and Definitions, words implying the masculine gender shall equally apply to and include the female gender.
Circumstances may necessitate adjustment in how Rules are applied for persons with physical handicaps. In particular and for example Section 3 Rule 14(c) cannot be applied to players in wheelchairs.
When there is no referee, such as in a social game, the opposing player will be regarded as such for the purpose of these Rules.

Section 4. The Players
