Billiards
Balls are driven with a cue around a cushioned table; the tighter the pockets, the dearer precision becomes.
Nine-foot table
A smaller table, with wide pockets.
Nine feet (2.74 m) long. The pockets are noticeably wider than the ball and the table is shorter. Potting is easier, and so the game is less about making the ball than about where the cue ball will stand for the next stroke.
Pool balls
Under these rules: The balls from one to nine, and a cue ball.
Fifteen numbered coloured balls and a white cue ball.
The numbers and the colouring here are not decoration but rule: pool games are built on which ball is legal at any moment — by number, by group, or by call. Solids run from one to seven, stripes from nine to fifteen, with the black eight between them.
Cue
A long tapering stick used to strike the ball.
The stroke passes through the tip at the thin end — it decides where the ball goes after the collision and how it spins. Spin is exactly what separates billiards from simple pushing: a ball can be made to draw back, to stop dead, or to run off sideways after it has hit its target.
Rules of nine-ball
The balls
The balls from one to nine, and a .
Compulsory contact
On every stroke the cue ball must first touch the lowest-numbered ball remaining on the table.
Order
Potting the balls strictly in ascending order is not required: if another ball drops after a legal contact, it counts.
Winning
The player who legally pots the nine wins, however many balls are left on the table.
Worth knowing
A common form is given. The rules on fouls and on continuing a run are not opened up in the record.
