How To Set Up Billiards
A rack (sometimes called a triangle) is a piece of equipment that is used to place billiard balls in their starting positions at the beginning of a pocket billiards game. Rack may also be used equally a verb to draw the act of setting billiard balls in their starting positions (e.yard. "to rack the assurance"), or as a noun to draw a set of assurance that are in their starting positions (due east.thousand. "a rack of balls", more oft called a pack or a pyramid in British English).
Traditional racks are in the class of triangular frames, usually fabricated from woods, plastic or metal. A mod variation, called a template rack, is made from a sparse material (usually 0.fourteen mm or less) that contains precision cutting-outs to agree the balls in identify. Purported benefits of template racks include a more than consequent racking, and their popularity has warranted specific inclusion in profession rules.[ane] Unlike traditional racks, template racks are left on the tabular array during the intermission shot and removed at the players' earliest convenience. For this reason, template racks are almost never used for games where it is mutual to tiresome-intermission (i.due east. not create a large spread of balls) since it is significantly more likely that the rack will interfere with slow-rolling balls.
The well-nigh common shape of a rack is that of an equilateral triangle. Triangular racks are used for 8-brawl, straight pool, 1-pocket, bank pool, snooker and many other games. Diamond-shaped frames are sometimes used for the game of nine-ball (although a triangular rack tin can also be used) and template racks come in a diversity of shapes.
Racking in specific billiards games [edit]
8-ball [edit]

In eight-ball, 15 object assurance are used. Nether the world standardized rules, information technology is prescribed that:[two]
- The 8 ball must be in the centre of the rack (the second brawl in the three-assurance-wide row).
- The showtime brawl must be placed at the noon position (front of the rack and then the center of that ball is straight over the tabular array's foot spot ).
- The ii corner balls must exist a stripe and a solid.
- All balls other than the 8 ball are placed at random, but in conformance with the preceding corner ball rule.
- The balls should be pressed tightly together without gaps, every bit this allows the best break possible.
Nine-ball [edit]

In nine-brawl, the basic principles are the same as detailed in the eight-ball section above, but merely balls 1 through ix are used; the 1 ball is always placed at the rack's apex (considering in nine-ball every legal shot, including the intermission, must strike the lowest numbered ball first) over the table'south foot spot, and the 9 ball is placed in the center of the rack.
Some players (most oftentimes amateurs) place the balls in numeric gild but for the 9 ball; from the superlative of the triangle downwards and from left to correct, i.e., the ane on the foot spot, followed by the 2 and so 3 in the second row, and so on. Nonetheless, all balls other than the ane and ix may be randomly placed.
In ix-ball games where a handicap is given past one player being spotted a brawl , some tournament venues enforce a dominion that the spotted ball must be racked every bit one of the two assurance in the row direct backside the 1 ball.
Directly pool (14.1 continuous) [edit]
In the initial rack in straight pool, fifteen balls are racked in a triangular rack, with the center of the apex brawl placed over the human foot spot Traditionally, the ane ball is placed on the rack'due south right corner, and the 5 brawl on left corner from the racker's vantage point to maximize contrast between the corner assurance and the background, as the 1 and 5 are the brightest colored balls, still the world standardized rules do not crave this. All other balls are placed at random.
Straight pool is played to a specific number of points agreed on prior to the friction match's start, with each pocketed brawl being worth one point to the shooter. 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, 1-hundred l points), multiple intragame racks are necessary. Intragame racking employs a separate set of rules from those in place at the game'south start.
Later the initial rack, the assurance are played until only the cue brawl and ane object ball remain on the table's surface. At that time, the xiv pocketed balls are racked with no noon ball, and the rack is and so placed so that if the apex brawl were in the rack, its center would remainder directly over the table's foot spot. Play then continues with the cue brawl shot from where information technology rested and the fifteenth brawl from where it rested prior to racking.
A number of rules have developed which item what must exist 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 i or the other. The rules also vary depending on whether the cue ball or fifteenth ball are resting on the table's caput spot. Such rules are detailed on the post-obit chart (annotation therein that the kitchen refers to the area backside the tabular array'due south head cord ).
| 15th ball lies | Cue ball lies | ||
|---|---|---|---|
| In the rack | Not in the rack and not touching the head spot | Touching the head spot | |
| In the rack | 15th ball: foot spot Cue ball: in kitchen | 15th ball: head spot Cue brawl: in position | 15th brawl: center spot Cue ball: in position |
| Pocketed | 15th brawl: foot spot Cue brawl: in kitchen | 15th ball: foot spot Cue ball: in position | 15th brawl: foot spot Cue ball: in position |
| Behind head string but not on caput spot | 15th brawl: in position Cue ball: head spot | ||
| Not behind caput string and not in the rack | 15th ball: in position Cue ball: in kitchen | ||
| On caput spot | 15th ball: in position Cue ball: center spot | ||
I-pocket and bank pool [edit]
In both one-pocket and banking concern pool all 15 object balls are racked entirely at random, with the center of the apex ball placed straight over the human foot spot.
Snooker [edit]
Snooker table in starting position
Snooker is played on a big table (total, pro tournament size is 12 × six ft). It is played using a cue stick, i white ball (the cue ball), 15 red balls and six colours: a xanthous (worth 2 points), green (three points), brown (4 points), blue (five points), pink (six points) and black ball (seven points). At one end of the table (the "baulk end" ) is the so-called baulk line , which is 29 inches from the baulk terminate cushion. A semicircle of radius 11.five inches, called the "D" , is drawn behind this line, centred on the middle of the line.
On the baulk line, looking up the tabular array from the 'baulk terminate', the xanthous ball is located where the "D" meets the line on the right, the light-green ball where the "D" meets the line on the left, and the brown brawl in the middle of the line. An easy mode to remember these positions is with the mnemonic, 'God Bless Y'all', with the outset letter of each discussion beingness the first letter of the three colours as they are racked from left to right on the baulk line. At the exact middle of the table sits the blueish ball. Further up the table is the pink brawl, which sits midway between the bluish spot and the meridian cushion, followed past the red balls (one each), placed in a tightly-packed triangle backside the pink. The noon must be every bit shut every bit possible to the pink ball without touching it. Finally, the black ball is placed on a spot 12.75 inches from the top absorber on a full-size table.
Coloured ball racking positions must be remembered with intendance, equally each time a coloured ball is potted, it is immediately replaced to its starting position, which occurs multiple times per frame, whereas reds are non returned to the table's surface afterward being potted.
If the starting position spot for a coloured ball is covered past another ball, the ball is placed on the highest available spot. If there is no available spot, it is placed equally close to its own spot equally 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, information technology will exist placed equally close to the spot as possible in a direct line towards the bottom cushion, without touching some other brawl.
