Bank pool has been gaining popularity in recent years. Bank pool can be played with a full rack (can be a long game), but is more typically played with nine balls (frequently called "nine-ball bank"). The balls are racked in nine-ball formation, but in no particular order.
The object of the game is simple: to be the first player to bank five balls in any order (eight balls when played with a full rack). Penalties and fouls are similar to one pocket in that the player committing the foul must spot a ball for each foul. This must be done before the incoming player shoots.
