Scorekeeper for the pool game of Ninety-Nine
The game of Ninety-Nine (or simply '99') was created by Pool & Billiard Magazine. The original rules can be found here. The modified rules for this version are below.
'99' is played with nine object balls numbered one through nine, and a cue ball. For those familiar with 'playing the Ghost', '99' is like playing the 9-ball Ghost but a partial score is awarded for breaking well and pocketing balls.
Play is divided into Nine Frames (racks) for each player, with a maximum Frame Score of 11 (Eleven) Points, and thus a maximum Game Score of 99 Points. On each shot after the break, the first ball contacted by the cue ball must be the lowest numbered ball on the table. When this requirement is met on a legal shot, any ball pocketed as a result is scored and allows the player to continue their frame. A player’s frame will end when they fail to legally pocket a ball, commit a foul, or complete the frame by legally pocketing the last ball. The incoming player then begins their frame with a new rack and play rotates after each frame ends. If the player is playing alone, they re-rack the balls and begin the next frame and continue in the same manner for each frame.
The object balls are racked in a normal 9-ball diamond shape. With the 1-ball on the foot spot, the 9-ball in the center and the remaing balls racked randomly. Each player racks for themself.
Players begin each frame with the cue ball “in hand” behind the head string. After the break, no matter what the outcome, the player begins with ball in hand anywhere on the table, and continues until the player fails to legally pocket a ball or pockets all the balls. Balls pocketed on the break and all legally pocketed balls after the break, count as one point each toward the player’s “Ball Count” points (see Scoring). Scratching on the break does NOT end the player’s frame, and balls made on a “Scratch Break” are treated just as if the player did not scratch. They stay off the table and are counted in the player’s “Ball Count” score for the frame. However, if the nine ball is made on a break in which the player scratches, remains off the table and the player continues the frame. A nine ball made on a any break is counted as 2 “Ball Count” points.
If the player legally pockets one or more balls on the break, they are awarded 1 “Break Bonus” point.
Balls pocketed during a scratch on the break are counted toward a players “Ball Count” for the frame, however the Break Bonus is not awarded because of the scratch.
The total number of object balls pocketed both during and legally after the break during a frame. A maximum of 10 “Ball Count” points are available in each frame. The 9-ball has a value of 2 "Ball Count" points and each of the other balls has a value of 1 "Ball Count" point.
Pocketing the 9-ball on the break shot or as a combination during the frame does not end the frame. The 9-Ball is counted as 2 "Ball Count" points and the player continues until a missed shot or pocketing the remaing balls.
Balls pocketed on a Scratch (except on the break), foul or other illegal shot DO NOT count toward a player’s score and end the frame. Touching an object ball is not a foul (cue ball fouls only), but a disturbed object ball must be replaced as close as possible to its original position. Driving an object ball off the table on any shot (except on the break) is a foul and ends the player’s frame. An un-pocketed object ball is considered to be driven off the table if it comes to rest anywhere other than the playing surface. balls driven off the table on the break shot will be spotted as closely as possible to the foot spot.
The use of break cues and jump cues is allowed. Use of template ("magic") racks is legal.
