TYPE OF GAME

CT-12-9 is variation of Cutthroat that uses 12 numbered balls and 9 solid color (no number) balls.   To win this game, the player must be the only shooter left in the game.

WARNING:   This game is HEAVY on Combinations and Caroms.

The game requires a combination or carom as the start of every scoring shot.   Combinations must start by striking one of the shooter's non-numbered balls first.   Caroms must strike one of the opponents' non-numbered balls first.

PLAYERS

Three (or three teams).

BALLS USED

The standard set of object-balls numbered 1-15 and cue-ball, plus 9 non-numbered balls (3 Yellows, 3 Reds, and 3 Blacks).   (The numbered balls 3, 8, and 13 are not used.)   The balls are split into three groups.

  1. Balls 1-5 plus Yellows  (low group, first shooter).
  2. Balls 6-10 plus Reds  (middle group, second shooter).
  3. Balls 11-15 plus Blacks  (high group, last shooter).

THE RACK

A 21-ball (baseball) triangle rack is used.   The apex is on the foot spot.   There should be an equal distribution of each group of balls in the various areas of the rack.   The following will achieve this.

Here is a sample rack.

                             Y
                           11 9  
                          10 Y 12
                         5  R B  4
                        6 15 Y 7 14
                       B 2  B R  1 R

OBJECT OF THE GAME

To be the only one with balls from his group on the table.   Balls are taken off the table by being pocketed on legal shots, or by being "dropped" as payment for a foul.

If after a player's turn there are no non-numbered balls on the table then one non-numbered ball for each player will be spotted before the incoming player takes their turn.   (See spotting non-numbered balls below.)

RULES OF PLAY

A player must have a numbered ball, from his group, on the table to be in the shooting order.

Legal scoring shots can be of two types.

  1. Starts as a COMBINATION
    At least one of the shooter's non-numbered balls must be involved in the combination action.

  2. Starts as a CAROM
    At least one non-numbered ball of either opponent must be involved in the carom action.

A player may shoot at any ball that he chooses, but before he shoots he must declare the ball and the intended pocket.   He need not call any detail such as kisses, caroms, combinations, or cushions.

Shooter continues at the table as long as he legally pockets any of his opponents' group or any of his numbered balls.   On any stroke where shooter drops any of his non-numbered balls his turn is over and the non-numbered ball(s) dropped stay down.

If a player sinks his last numbered ball he can still win the game that inning if he clears the table of his opponents' numbered balls.

Any time the shooter sinks any of his balls they will stay down, whether called or not.

OPENING BREAK

Shooting order is determined by lot or lag.   The player being third in the shooting order will rack the balls, while the player shooting first will break them.

The starting player must make an open break or pocket a ball.   If he fails to do so it is an illegal break (not a foul) and the next player in the shooting order has the choice of either:

  1. accepting the table in position and shooting, or
  2. having the balls re-racked and shooting the opening break shot himself.

Any balls which fall from a legal opening break count as legally pocketed balls if there were no fouls (note that a scratch is a foul).   The breaker continues to shoot.

If the breaker drops any of his non-numbered balls those will spot (see SPOTTING).   If any of the breaker's numbered balls drop they will stay down.

Should a player foul on a legal opening break, their opponent has cue-ball in hand behind the head string.   Any balls made on a foul break must be spotted (except for the breaker's numbered balls).   In addition the breaker must then "drop" (take it off the table and put it in a pocket) one of his numbered balls to pay for the foul.

LOSS OF GAME

Does not occur until the game is won.   This is necessary since a player can be put out of the game (when his last numbered ball is pocketed -- at the end of his inning if he pocketed it) and then later be brought back into the game by one of his opponents choosing to spot one of his numbered balls to pay for a foul they committed.

(When the game is over the last person to have been put out is the second player of the next game, the winner becomes the breaker, and the last person racks for the next game.   This usually results in a shuffling of who has which group from one game to the next.)

SPOTTING BALLS

Numbered balls will spot as usual (to the foot spot).

Non-numbered balls will spot around the center spot in a cross pattern as follows.   The first ball spotted will be on the center spot (if not possible proceed as spotting the second ball).   The next ball is spotted, on a 45-degree line, foot-ward of the center-string and on the right side of the table, with its center seeking the center spot.   Additional non-numbered balls that need spotting will continue clockwise along lines 45-degrees out from the center spot.

ILLEGALLY POCKETED BALLS

Any of the shooter's numbered balls pocketed on an illegal shot will not be spotted.   (Note that an uncalled shot is deemed an illegal shot.)

JUMPED OBJECT BALLS

Jumped balls will be spotted if they do not belong to the shooter.   If the jumped balls (numbered or non-numbered) belong to the shooter they will stay off the table.   The stroke is a foul.

CUE-BALL AFTER SCRATCH OR FOUL

Each of these requires the shooter to either:

After the penalty has been paid the cue ball is put in play from:

  1. Jumped (off table) -- out of the kitchen (from behind the head string).
  2. Scratch -- out of the kitchen (from behind the head string).
  3. Foul -- where it came to rest.
