Cue sports are commonly known as the billiard sports. These sports consist of variety of games of skills which are generally played with a cue stick to hit the billiards balls. Sports cue has a quite long and rich history expanding from its beginning in the 15th century; to the wrapping of the body of Mary, Queen of Scots in her billiard table cover in 1586. However, all sports cue are generally considered to have evolved into indoor games from outdoor stick-and-ball lawn games and as such to be related to trucco, croquet and golf. However, the cue sports as we see today were developed during 1800s.
There are mainly three sub categories of games within professional cue sports including carom billiards, pool and snooker. Carom refers to games that are played on tables which have no pockets including among others, balkline and straight rail, cushion caroms, three cushions billiards and artistic billiards. Pool is basically played on a six pockets table, including among others eight balls, nine-ball, straight pool, one-pocket and bank pool. However, snooker is technically a pocket billiards game, and is categorized separately based on its historic divergence from other games, as well as a separate culture and terminology that characterize its play.
Since 1983, the games with regulated international professional competition have been referred to as "sports" or "sporting" events, not simply "games. Many of the variety of the of the particular games are the subject of present-day competition, including many of those already mentioned, with competition being especially broad in nine-ball, snooker, three-cushion and eight-ball. More obscurely, there are games that make use of obstacles and targets, and table-top games played with disks instead of balls. Snooker, being technically a pocket billiards variant, closely related to its equipment and origin to the game of English billiards, is a professional sport organized at the international level, and its rules bear little resemblance to those of pool games.
A ‘billiards’ category extensively pool, snooker and carom was featured in the World Games 2005 which was held in Duisburg, Germany. Moreover, we saw the introduction of cue sports category in the Asian Games 2006.
