From the box:
Welcome to the Roaring Twenties! It's the heyday of organized crime in Chicago and you are the boss!
You must take control of legal and illegal sources of profit: speakeasies, gambling houses, jazz clubs, and breweries.
You could do this by sending a few of your boys down to intimidate the owners, but sometimes it's easier to take over at the poker table!
The first boss to take control of the racket becomes teh winner of Chicago Poker!
Chicago Poker includes 20 hexagonal "business" tiles, 87 cards, 4 shootout markers, and 1 rules booklet.
