1. Requirements of the Game
The billiards game shall be known as 9-Ball is a game played with a cue ball and nine object balls, numbered 1 through 9. In our game it is played on 9 foot Tournament billiard table, with play field size 4.5 X 9 foot = 50 inches by 100 inches; the balls used are 57,2 mm diameter.
Initially the numbered balls are racked with the 1-ball on the foot spot, the 9-ball in the center of the diamond, and the other balls in random order in a diamond formation. The game begins with cue ball in hand behind the head string.
2. Object of the Game
On each shot, the first ball the cue ball contacts, must be the lowest numbered ball on the table, and the shooter must pocket any numbered ball, or cause the cue ball or any numbered ball to contact a rail. If a player pockets any ball on a legal shot, he remains at the table for another shot, and continues until he misses, fouls, or wins the game by pocketing the 9-ball.
After a miss, the incoming player must shoot from the position left by the previous player. After any foul, the incoming player may start with the cue ball in hand anywhere on the table.
At any time, a player legally pots the 9-ball wins the frame.
3. The Legal Break shot
On the opening break the breaker must strike the 1-ball first and either pocket a numbered ball or drive at least four numbered balls to the rail. It is a Legal Break shot.
If the cue ball is pocketed, or the requirements of the opening break are not met, it is a foul, and the incoming player has cue ball in hand anywhere on the table.
If the breaker pockets one or more balls on the break shot without a fouls, he continues to shoot until he misses, fouls, or wins the game; pocketing the 9-ball on the Legal Break shot wins the game.
On the shot immediately following a Legal Break shot, the shooter may play a Push Out. If a player fouls on the break shot, the incoming player cannot play a Push Out.
4. The Push-Out shot
On the first shot immediately after a Legal Break regardless of whether any balls were potted off the break, or who is at the table, a player have option to play a push-out shot. This means that for one shot only the player does not need to hit any object ball nor any rail, unless if the cue ball is pocketed, it is a foul.
Any ball pocketed on a push-out does not count and remains pocketed except the 9-ball, but the striker does not get to play another shot in that turn even if an object ball is pocketed.
Following a legal push-out, the incoming player accepts to shoot from that position, the game then continues as normal.
The push-out shot is extremely useful if you are snookered after the break.
When a player takes a shot, he must always hit the lowest numbered ball that is still on the table. Any numbered ball can be legally potted, so long as the lowest numbered ball is the first one the cue ball makes contact with.
Combination shots are allowed provided that the player hits the lowest numbered ball first. Moreover, the first contacted lowest numbered ball can be used in the middle of combination to legally pocket the 9-ball and wins the game!
If the player misses or fouls, the other player shoots until he misses, fouls, or wins.
If the first object ball contacted by the cue ball is not the lowest numbered ball on the table, the shot is a foul.
If no object ball is pocketed, failure to drive the cue ball or any numbered ball to a rail after the cue ball contacts the object ball is a foul.
If a shot is not played within defined time, it is a foul.
When a player commits a foul, any numbered object ball is pocketed on the same shot a foul is committed, unless it is the 9-ball, remain pocketed; the 9-ball is spotted at the foot spot; the incoming player is awarded ball in hand and may place the cue ball anywhere on the table.
7. Three consecutive fouls
If a player fouls three consecutive times on three successive shots without making an intervening legal shot, he loses the game.
8. The End of Game
The game ends when the 9-ball is pocketed on a legal shot, or when a player forfeits the game as the result of three consecutive fouls.
