Bank pool

Bank pool is a pool game that has as its most fundamental requirement that all scoring shots in the game must be made by banking a called ball off a cushion and into a called pocket.^[1]

While the game has multiple variations, the predominant version through much of its history was played with a full fifteen-ball rack, of which the winning player was required to legally pocket eight balls. A shortened version of the game using nine balls of which the players must legally pocket five for the win, often called "nine-ball banks," gained popularity in the 1990s and 2000s and is the subject of international professional competition and televised matches.
