Bottle pool is a billiards game. It combines aspects of both carom and pocket billiards. Played on a standard pool table, the game utilizes three balls and a narrow-necked bottle called a shake or tally bottle. The bottle is traditionally made from leather, and 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.
