Russian pyramid

• Table: Playing-surface sizes vary. The official tournament size is {{convert|12|x|6|ft|cm}}, the same size used for professional snooker. Smaller sizes as used by other cue sports are also found in less-formal venues. The {{cuegloss|slate}} used in Russian pyramid tables are typically much thinner than those of pool and snooker tables, but is occasionally heated, similar to carom billiards tables.
• Balls: There are sixteen balls, fifteen {{cuegloss|object ball|numbered object balls}} and a {{cuegloss|cue ball|cue ball}}, but in contrast to pool, the numbered balls are usually white, and the cue ball is red or yellow. They are typically larger and heavier than other types of billiard balls. The official tournament size is {{cvt|67|mm|in|frac=16}} in diameter, weighing approximately 255 g (9 oz), while smaller balls – e.g., {{cvt|63|mm|in|frac=16}}, {{cvt|60|mm|in|frac=16}}, and {{convert|57.15|mm|in|frac=16}} (regular pool ball size) – are available for smaller table sizes. The old tournament size was 68 mm in diameter.
• Pockets: The {{Cuegloss|Corner pocket|corner pockets}} are only 3 mm (approx. {{frac|3|16}} in) wider than the diameter of the ball, while the {{cuegloss|middle pocket|middle pockets}} are 12–13 mm (approx. {{frac|1|2}}–{{frac|3|4}} in) wider than the diameter of the ball. This requires great precision to pocket a ball in such tight pockets.
• Cues: Due to larger ball size, the cues used for Russian pyramid are slightly thicker and heavier than those of pool cues, and the tip diameter is wider (up to 15 mm), in comparison to 10–13 mm used in pool cues. Specialty shots like {{cuegloss|massé|massé}} and {{cuegloss|jump shot|jump shots}} are usually more difficult to perform with a Russian pyramid cue, due to its heavier nature. These shots are also not allowed in official tournaments, doing so may result in a {{cuegloss|foul}}.

There are several rule variations of Russian pyramid. All games begin with fifteen numbered white balls {{cuegloss|rack|racked}} in a {{cuegloss|pyramid}} {{cuegloss|pack}}, as in straight pool, eight-ball, and blackball. Players may pocket any object balls on the table regardless of number, and the first player to pocket eight or more balls wins the {{cuegloss|frame}}. In addition, shots do not have to be {{cuegloss|call shot|called}}.

Depending on the game variant, some specific balls may have to be in specific positions within the rack. The first player firmly {{cuegloss|break}}s the rack with the {{cuegloss|cue ball}} from just in front of the {{cuegloss|baulk line}}.

The most common varieties are the following, each of which has slight local variations on the rules:{{cite web |url=http://www.wpa-pool.com/pdf/web/Official%20International%20IPC%20Rules.pdf |title=Archived copy |website=www.wpa-pool.com |access-date=13 January 2022 |archive-url=https://web.archive.org/web/20161108220643/http://www.wpa-pool.com/pdf/web/Official%20International%20IPC%20Rules.pdf |archive-date=8 November 2016 |url-status=dead}}

• Free pyramid (also known as American pyramid)

:Any ball may be used as the cue ball. Players can pocket the ball they struck if it hits another ball first, with the goal being to {{cuegloss|carom}} the struck ball off one or more other balls into a pocket. Should the struck ball be pocketed without striking any other balls, the shot is a {{cuegloss|foul}}, and that ball is {{cuegloss|spotted}} behind the baulk line.{{Cite web|url=http://ebc-billiard.com/rules/pyramid/free-pyramid-rules|title=Free Pyramid rules - East European Billiard Council|website=ebc-billiard.com|access-date=2020-02-23}}

• Dynamic pyramid (also known as Siberian pyramid or Nevsky pyramid)

:Only one ball is the cue ball. Players can pocket the cue ball with a carom shot off another ball and then the scorer must choose an object ball to be taken off the table. The player then has {{cuegloss|ball-in-hand}} and may place it anywhere on the table but may not pocket it until the next stroke; otherwise, it is a foul.

• Combined pyramid (also known as Moscow pyramid or combo pyramid)

:The rules are the same as in dynamic pyramid, except that, after the cue ball is pocketed, the cue ball is spotted between the {{cuegloss|head rail}} ({{cuegloss|bottom cushion}}) and head or baulk, but not on top of that line; from here until the next stroke, balls can be only pocketed in the side and far-corner pockets. In pool, this part of the table is called the {{cuegloss|kitchen}} and the Russian equivalent is {{lang|ru|дом}} (dom), 'house'.

• Classical pyramid

:The rules are similar to fifteen-ball pool. The object is to score at least 71 points. For each correctly pocketed object ball, the player wins the number of points on the ball (except for the 1-ball, which scores 11 points). The last remaining ball on the table, regardless of its number, is worth 10 points. The total number of points is 130.{{cite web |url=http://www.billiard-prime.com/en/poleznaya-informaciya/pravila-russkoy-piramidy/classic-piramid.html |url-status=usurped |archive-url=https://web.archive.org/web/20180522042710/http://www.billiard-prime.com/en/poleznaya-informaciya/pravila-russkoy-piramidy/classic-piramid.html |archive-date=2018-05-22 |title=Classical pyramid}}

• 14.1 pyramid (also known as straight pyramid or long pyramid)

:The rules are very similar to free pyramid, except that a frame continues until 14 balls are pocketed, similar to straight pool; these 14 balls are then re-spotted into an incomplete pyramid.{{cite web|url=https://www.llb.su/rules/pyramid/14+1_llb|title=Свободная пирамида с продолжением ЛЛБ|access-date=2022-08-20|website=lib.su}} The objective is to score at least a given number of points.

• Scratch pyramid (also known as SVOI)

:Similar to free pyramid, but pocketing object balls before the cue ball is a foul; therefore, the player must pocket the cue ball after hitting object balls. Other balls can be pocketed as long as the cue ball is potted first.{{cite web|url=https://www.gamezer.com/en/rules/billiards/scratch_pyramid|title=Scratch Pyramid|access-date=2022-08-22|website=gamezer.com}}

Versions of the game have featured prominently in notable Russian films such as The Meeting Place Cannot Be Changed (1979) and The New Adventures of the Elusive Avengers (1968). An episode of the popular animated television series Kikoriki has two characters playing the game. The main characters of Dead Man's Bluff, or Zhmurki (Russian: Жмурки) play Russian pool in the bar scene.

A Russian pool configuration can be seen in “Tulsa King” starring Sylvester Stallone in Season 1, episode 5, while making a phone call, he walks around a pool table with all-white balls racked, and a white cue ball.

Russian pyramid has been adapted into video games, both in stand-alone form and as a play mode in multi-cue-sports video games. Many recent releases have been mobile games for Android and iOS.{{cn|date=August 2022}}

Colored numbered balls for playing eight-ball, nine-ball, and other pool games on Russian billiards tables are also produced. The balls are 68 mm ({{frac|2|11|16}} in) in diameter, like the standard ones for Russian pyramid, and thus much larger than the American-style balls they are patterned after {{crossreference|(as illustrated in the comparison image)}}.

Sanctioned by the World Pool-Billiard Association (WPA).
