Not only does the slate weigh a lot (450 pounds, on average), but the rest of the table weighs a lot, too. At one end of the table (the "baulk end" ) is the so-called baulk line, which is 29 inches from the baulk end cushion. After the initial rack, what is billiards the balls are played until only the cue ball and one object ball remain on the table's surface. A player wins the game if that player legally pockets the 8 ball into a designated pocket after all of their object balls have been pocketed. "Gotta have some chalk, gotta have some chalk," I’ll mumble, as I walk in circles around the pool table, looking underneath it and in all the pockets until I find some. The standard pool table, however consists of 6 pockets that are enclosed at the table edges. The evolution to what we in America know as Pool has been long and drawn out. The English refer to this technique as 'side', only in America is it alluded to as 'English'. If you imagine the cue ball with different markings, it’s easy to understand English.

The rules also vary depending on whether the cue ball or fifteenth ball are resting on the table's head spot. Nitrocellulose (also known as cellulose nitrate, flash paper, flash cotton, guncotton, pyroxylin and flash string, depending on form) is a highly flammable compound formed by nitrating cellulose through exposure to a mixture of nitric acid and sulfuric acid. Depending on the manufacturing process, nitrocellulose is esterified to varying degrees. In 2014, the Philae comet lander failed to deploy its harpoons because its 0.3 grams of nitrocellulose propulsion charges failed to fire during the landing. Nitrocellulose lacquer is spin-coated onto aluminium or glass discs, then a groove is cut with a lathe, to make one-off phonograph records, used as masters for pressing or for play in dance clubs. Guncotton, dissolved at about 25% in acetone, forms a lacquer used in preliminary stages of wood finishing to develop a hard finish with a deep lustre. In the form of collodion it was also a critical component in an early photographic emulsion, the use of which revolutionized photography in the 1860s. In the 20th century it was adapted to automobile lacquer and adhesives.

The film was also used for many years in the field of medicine, where its hazardous nature was most acute, especially in its application to X-ray photography. Collodion, a solution of nitrocellulose, is used today in topical skin applications, such as liquid skin and in the application of salicylic acid, the active ingredient in Compound W wart remover. Nail polish contains nitrocellulose, as it is inexpensive, dries quickly to a hard film, and does not damage skin. Magicians' flash paper are sheets of paper consisting of pure nitrocellulose, which burn almost instantly with a bright flash, leaving no ash or smoke. A nitrocellulose slide, nitrocellulose membrane, or nitrocellulose paper is a sticky membrane used for immobilizing nucleic acids in southern blots and northern blots. A few years later in 1838, another French chemist, Théophile-Jules Pelouze (teacher of Ascanio Sobrero and Alfred Nobel), treated paper and cardboard in the same way. Around 1846 Christian Friedrich Schönbein, a German-Swiss chemist, discovered a more practical formulation. The decision largely depends on personal preference and whether the table is more for practice or decoration. Naturally, it also helps to clean your pool table often! You’ll rarely find any other color in pool halls or tournament settings.

Snooker is played on a large table (full, pro tournament size is 12 × 6 ft). There is an especially large interest in competitive success among players in Egypt. There are many varieties of billiards played all over the world. World Championship: What makes the perfect snooker player? In nine-ball games where a handicap is given by one player being spotted a ball, some tournament venues enforce a rule that the spotted ball must be racked as one of the two balls in the row directly behind the 1 ball. When scratching on an 8 ball shot, the offending player forfeits the game to his or her opponent and the game is over. In nine-ball, the basic principles are the same as detailed in the eight-ball section above, but only balls 1 through 9 are used; the 1 ball is always placed at the rack's apex (because in nine-ball every legal shot, including the break, must strike the lowest numbered ball first) over the table's foot spot, and the 9 ball is placed in the center of the rack. The 8 ball must be in the center of the rack (the second ball in the three-balls-wide row).
