Key West: Mafiosi expansion is an expansion for Key West released in 2011 for 3–5 players, 60 minutes per game, and ages 12 and up. Its main mechanics are Auction / Bidding and Action Points.
Two Mafiosi cards will be placed on two of the seven Key West decks already assembled. Both decks have to be placed aside, they are used in play rounds 6 and 7. In those rounds, during the bid phase, 7 instead of 6 cards are available. In round 8 again only 6 Key West cards can be used. The player who obtains a Mafiosi card acts immediately in the following way: He removes a wood disk which indicates the ownership of a hotel, a factory or a plantation and gives it back to the owner. Instead he places one of his own wood disks. This replacement is free of charge.
Key West: Mafiosi expansion supports 3–5 players according to the catalogue. This range comes from the publisher’s listed player count, so the game can be set up for any group size within it. Some setups, rules and scoring details may still vary by player count, so check your edition’s rulebook for the exact configuration.
The listed playing time for Key West: Mafiosi expansion is 60 minutes. This is the publisher’s estimate for a full game.

Setup and teaching time are not included in this estimate.
The catalogue lists Key West: Mafiosi expansion for ages 12 and up. This is the publisher’s recommendation and reflects reading demands, rule complexity and small components rather than theme alone. Younger players can often join with help from an adult, so check the age guidance on your edition and consider your group’s experience with board games.
