Mystery Rummy: Al Capone and the Chicago Underworld is a board game released in 2003 for 2–4 players, 20–40 minutes per game, and ages 8 and up. It was designed by Mike Fitzgerald and Nick Sauer and its main mechanics are Hand Management and Set Collection.
Mystery Rummy: Al Capone and the Chicago Underworld, the fourth title in the Mystery Rummy series, introduces some elements of Canasta with players scoring bonuses for collecting complete sets. Sets have varying numbers of cards in them, from Mike Heitler with four cards up to Al Capone with eight. The four types of gavel card make cards accessible everywhere: "Agent Meeting" searches other players' hands, "Eliot Ness" searches the deck, "Search Warrant" looks in the discard pile, and "Raid" allows you to take an opponent's already melded cards, provided you have at least three melded. All these mechanisms help make completing entire sets for their bonuses something you can reasonably strive for – while also putting you on guard against your opponent doing the same.
Mystery Rummy: Al Capone and the Chicago Underworld supports 2–4 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 Mystery Rummy: Al Capone and the Chicago Underworld is 20–40 minutes. This is the publisher’s estimate for a full game.

Setup and teaching time are not included in this estimate.
