Chicago (pool)

Chicago is a "money ball" pool gambling game.

"Chicago" often refers to a variation of rotation pool in which the balls are initially placed in positions against the rails of the table.

Another variation of Chicago is played in a similar fashion to nine-ball and rotation, where balls must be played in order starting with the 1 ball. In Chicago, all fifteen balls are used. The money balls are the 1, 5, 8, 10, 13 and 15. These six balls are racked to the front of the rack with the 1 ball at the head of the rack. A player continues his turn as long as a ball is pocketed. A score is kept as to how many money balls are made by each player.

Once all balls are pocketed the players will "settle up" based on the amount of money balls they made during the game. The loser pays the winner a previously agreed upon amount multiplied by the difference in money balls between the two players (i.e., if Player A makes five money balls and Player B makes one then Player B owes Player A four times the amount of the wager.)

The game can also simply be played recreationally for points instead of money.

Fouls: If a player does not hit the object ball it is considered a push. In the event of a push the incoming player has the option to either take the next shot or give it back to the person who pushed. If there are two fouls in a row, the incoming player gets ball in hand anywhere on the table. A scratch, i.e. pocketing the cue ball, results in ball in hand behind the headstring, and the incoming player must shoot at object balls forward of that line.
