In little time, you’ll also be able to make a few more tricks of your own. At that time, the fourteen pocketed balls are racked with no apex ball, and the rack is so placed so that if the apex ball were in the rack, its center would rest directly over the table's foot spot. In both one-pocket and bank pool all fifteen object balls are racked entirely at random, with the center of the apex ball placed directly over the foot spot. If a player commits a table scratch, the opposing player takes over with ball in hand anywhere on the table. British style pool is another billiard game that makes use of 15 object balls and a cue ball. Because the game is played to a number of points normally far in excess of the fifteen points total available in the initial rack (in tournament play, one-hundred fifty points), multiple intragame racks are necessary.

Straight pool is played to a specific number of points agreed on prior to the match's start, with each pocketed ball being worth one point to the shooter. It is played using a cue stick, one white ball (the cue ball), fifteen red balls and six colours: a yellow (worth two points), green (three points), brown (four points), blue (five points), pink (six points) and black ball (seven points). Finally, the black ball is placed on a spot 12.75 inches from the top cushion on a full-size table. The game of English billiards is played on a relatively large table, usually 6 feet 1.5 inches by 12 feet (1.9 by 3.7 m); it is played with three balls as in carom-a plain white, a white with a spot, and a red. At one end of the table (the "baulk end" ) is the so-called baulk line, which is 29 inches from the baulk end cushion. The acid mixture was changed to two parts sulfuric acid to one part nitric. The yields are about 85%, with losses attributed to complete oxidation of the cellulose to oxalic acid.

The process uses a mixture of nitric acid and sulfuric acid to convert cellulose into nitrocellulose. The principal uses of cellulose nitrate is for the production of lacquers and coatings, explosives, and celluloid. One of its first major uses was as guncotton, a replacement for gunpowder as propellant in firearms. Because of this, it is possible for a game to end with only one of the players having shot, which is known as "running the table" or a "denial"; conversely, it's also possible to win a game without taking a shot; such a scenario may occur if the opposing player illegally pockets the 8 ball on any shot other than the break (such as sinking the 8 ball in an uncalled pocket, knocking the 8 ball off the table, sinking the 8 ball when a player is not yet on the black ball, or sinking both the 8 ball and the cue ball off a single shot).

If there is no available spot, it is placed as close to its own spot as possible in a direct line between that spot and the top (black end) cushion, without touching another ball. If there is no room this side of the spot, it will be placed as close to the spot as possible in a straight line towards the bottom cushion, without touching another ball. Further up the table is the pink ball, which sits midway between the blue spot and the top cushion, followed by the red balls (one each), placed in a tightly-packed triangle behind the pink. The apex must be as close as possible to the pink ball without touching it. A number of rules have developed which detail what must be done when one or both of the cue ball and fifteenth object ball are either in the rack area at the time an intragame rack is necessary, or are in such close proximity to the intragame racking area, that the physical rack cannot be used without moving the one or the other. Millions of individuals play casually, using informal "house rules" which vary not only from area to area but even from venue to venue.
