==Variants==
Some versions of snooker, such as [[six-red]] or [[ten-red snooker]], are played with almost identical rules to the standard game but with fewer object balls, reducing the time taken to play each frame.<ref name="BBC Super 6" /><ref name="WPBSA_Official_Rules" />{{rp|34}} The [[Six-red World Championship|{{nowrap|Six-red}} World Championship]], contested annually in [[Bangkok]], Thailand, was a regular fixture on the World Snooker Tour between [[2012 Six-red World Championship|2012]] and [[2023 Six-red World Championship|2023]].<ref name="WST Six Red History" /> A World Women's {{nowrap|10-Red}} Championship was held annually in Leeds, England, from 2017 to 2019.<ref name="S1tVF" /><ref name="NOKNf" /><ref name="c4a7C" />

Geographic variations exist in the United States and Brazil, while speed versions of the standard game have been developed in the United Kingdom. [[American snooker]] is an amateur version of the game played almost exclusively in the United States.{{sfn|Collender|1925|pages=40–48}} With simplified rules and generally played on smaller tables, this variant dates back to 1925.{{efn|Despite its name, American snooker is not governed or recognised by the [[United States Snooker Association]], but by the [[Billiard Congress of America]].<ref name="BCA 2008" />}}{{sfn|Collender|1925|pages=40–48}} ''[[Sinuca brasileira]]'' (or "Brazilian snooker") is a variant of snooker played exclusively in Brazil, with fully divergent rules from the standard game and using only one red ball instead of fifteen. At the start of the game, the single red is positioned halfway between the pink ball and the side cushion, and the {{nowrap|break-off}} shot cannot be used to pot the red or place the opponent in a snooker.<ref name="sinu_Hist" /> The [[Snooker Shoot Out]] is a variant snooker tournament consisting of single frame matches for an accelerated format. First staged in [[1990 Shoot-Out|1990]], the idea was resurrected in [[2011 Snooker Shoot-Out|2011]] with a modified version that was added to the professional tour in the [[2010–11 snooker season|2010–11 season]] and upgraded to a ranking event in [[2017 Snooker Shoot Out|2017]].<ref name="Eurosport shoot out" /><ref name="7DxzR" />

Other games have been designed with an increased number of object balls in play. One example is "snooker plus", which included two additional colours: an orange ball worth eight points positioned between pink and blue, and a purple ball worth ten points positioned between brown and blue, increasing the maximum possible break to 210.<ref name="8NWyU" /> Introduced at the [[1959 News of the World Snooker Plus Tournament]], this variant failed to gain popularity and is no longer played.{{sfn|Shamos|2002|pp=140–150}} [[Power Snooker]] was a {{nowrap|short-lived}} cue sport based on aspects of snooker and pool; this was first played competitively in [[2010 Power Snooker Masters Trophy|2010]] and again in [[2011 Power Snooker Masters Trophy|2011]], but the format was discontinued after it failed to gain widespread appeal.<ref name="Eurosport shoot out" /> Using nine red balls racked in a diamond shaped pack at the start of the game, the matches were limited to a fixed {{nowrap|game-play}} period of 30&nbsp;minutes.<ref name="GuardianPower" /> [[Tenball]] was a snooker variant designed specifically for the television show of the same name, an [[LWT]] production that was broadcast for one series in 1995. An extra ball worth ten points (the yellow and black "tenball") was added between the blue and pink, and the game had a slightly revised set of rules compared to the standard game.<ref name="ukgameshow" />
