Slate bed tables usually feature sturdier frame construction that can hold up better to both the elements that sneak into the garage and the normal wear-and-tear that comes from playing. This allows for a broad spectrum of light that should cover the bed of the table and reduce or eliminate dim spots. The classic green has been the reigning champ for many years - after all, it was the original pool table cloth color - but Tournament Blue has become more popular in recent years, especially in televised tournaments. The Color of Money (film), Richard Price (screenplay, based on the novel by Walter Tevis), Martin Scorsese (director), 1986; uses a lot of pool terminology in-context. In terms of lacquers and coatings, nitrocellulose dissolves readily in organic solvents, which upon evaporation leave a colorless, transparent, flexible film. Nitrocellulose lacquers have been used as a finish on furniture and musical instruments. Most lacquers are prepared from the dinitrate, whereas explosives are mainly the trinitrate. The principal uses of cellulose nitrate is for the production of lacquers and coatings, explosives, and celluloid. In precise chemical terms, nitrocellulose is not a nitro compound, but a nitrate ester. Membrane filters made of a mesh of nitrocellulose threads with various porosities are used in laboratory procedures for particle retention and cell capture in liquid or gaseous solutions and, reversely, obtaining particle-free filtrates.

The rules also vary depending on whether the cue ball or fifteenth ball are resting on the table's head spot. These three - billiards, pool, and snooker - all use cue sticks, tables, and balls. 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. 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. The glucose repeat unit (anhydroglucose) within the cellulose chain has three OH groups, each of which can form a nitrate ester. 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). 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.

In the initial rack in straight pool, fifteen balls are racked in a triangular rack, with the center of the apex ball placed over the 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. 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 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. Some players (most often amateurs) place the balls in numeric order but for the 9 ball; from the top of the triangle down and from left to right, i.e., the 1 on the foot spot, followed by the 2 then 3 in the second row, and so on.

On the baulk line, looking up the table from the 'baulk end', the yellow ball is located where the "D" meets the line on the right, the green ball where the "D" meets the line on the left, and the brown ball in the middle of the line. At one end of the table (the "baulk end" ) is the so-called baulk line, which is 29 inches from the baulk end cushion.

However, purely negative play is rarely a winning strategy; successful players (in all versions other than golf croquet) will use all four balls to set up a break for themselves, rather than simply making the game as difficult as possible for their opponents. As of 2023, the Golf Croquet World Champion was Matthew Essick (USA), and the Women's Golf Croquet World Champion was Jamie Gumbrell (Australia). World Pool-Billiards Association (March 15, 2016). "Pool Billiards - The Rules of Play" (PDF). Traditionally, the 1 ball is placed on the rack’s right corner, and the 5 ball on the left corner from the racker's vantage point to maximize contrast between the corner balls and the background, as the 1 and 5 are the brightest colored balls, however, what is billiards the world standardized rules do not require this.
