Cue sports (sometimes written cuesports), also known as billiard sports,[1][2] are a wide variety of games of skill generally played with a cue stick, which is used to strike billiard balls and thereby cause them to move around a cloth-covered billiards table bounded by elastic bumpers known as cushions.

Historically, the umbrella term was billiards. While that familiar name is still employed by some as a generic label for all such games, the word’s usage has splintered into more exclusive competing meanings in various parts of the world. For example, in British and Australian English, “billiards” usually refers exclusively to the game of English billiards, while in American and Canadian English it is sometimes used to refer to a particular game or class of games, or to all cue games in general, depending upon dialectand context. In colloquial usage, the term “billiards” may be used colloquially to refer to pocket billiards games, such as poolsnooker, or Russian pyramid.

There are 3 major subdivisions of games within cue sports:

There are other variants that make use of obstacles and targets, and table-top games played with disks instead of balls.

Billiards has a long and rich history stretching from its inception in the 15th century, to the wrapping of the body of Mary, Queen of Scots, in her billiard table cover in 1586, through its many mentions in the works of Shakespeare, including the famous line “let’s to billiards” in Antony and Cleopatra (1606–07), and through the many famous enthusiasts of the sport such as: MozartLouis XIV of FranceMarie AntoinetteImmanuel KantNapoleonAbraham LincolnMark TwainGeorge Washington, French president Jules GrévyCharles DickensGeorge Armstrong CusterTheodore RooseveltLewis CarrollW.C. FieldsBabe RuthBob Hope, and Jackie Gleason.
