CAPO is played with two decks: CAPO cards and Territory cards. CAPO cards represent the city's five mafia families and are numbered from 1 - 10 (#1 being the CAPO) and also contains two Polizia (police) cards. Territory cards depict the city's districts. The game's objective is to collect 4 Territory cards of the same color. Territory cards can be obtained by winning a round or winning a 'Battle'. During a round players try to be the first to get rid of their CAPO cards and win a Territory card. Players can get rid of their cards by playing one card, two cards (a duo) or a combination of 4 cards (a CAPO hand). Some cards have special features. The #9 (Cugine) for instance allows a player to challenge another player for a 'Battle'.
