Bottle pool

Bottle pool, also known as bottle-billiards and bottle pocket billiards, is a hybrid billiards game combining aspects of both carom billiards and pocket billiards. Played on a standard pool table, the game uses just two object balls, a cue ball, and a 6¾ inch (171 mm) tall, narrow-necked bottle called a shake bottle or tally bottle, traditionally made from leather, that is placed on the table and used as a target for caroms. Those unfamiliar with the game sometimes mistakenly use its name as a synonym for the very different game of kelly pool. Bottle pool has been described as combining "elements of billiards, straight pool and chess under a set of rules that lavishly rewards strategic shot making and punishes mistakes with Sisyphean point reversals."

Although bottle pool's origins remain obscure, tournament records and newspaper articles confirm that the game has been played since at least the late 19th century. A mention appears in an 1894 New York Times newspaper article announcing a 64 player tournament to be played at a certain Hanover Clubhouse in Brooklyn, New York. The game was more well known in the early-to-mid-20th century, during which references to it appear in numerous books and publications including Sinclair Lewis's Main Street. It is also known to have been played by some notable individuals, such as world-renowned quantum chemist and biochemist Linus Pauling.
