Conspiracy is a board game released in 1973 for 3–4 players, 90 minutes per game, and ages 10 and up. It was designed by Eric Solomon and its main mechanics are Memory, Betting and Bluffing, and Pick-up and Deliver.
There are four capitals, four bankbooks, one top secret briefcase and eight greedy spies that anyone can control. The object is to move the briefcase to your headquarters. Players can either secretly pay off or openly move a spy one space on their turn. Each player has an account of $10,000 and can bribe spies in increments of at least $100. If you move a spy, another player may challenge the move. The two players then slowly reveal how much money they each have on the spy in question. If the challenger wins, the move is rescinded. If the defender wins, the move stays and the challenger loses his next turn. Players need to cooperate against whichever player is closest to victory. You can conspire openly to swipe the case or murder a spy and turn the tables on a player who is a mere one space away from winning. No dice, no cards, no luck involved. Learn to work together or games will end in a hurry. Amigo version (Casablanca) published 1991 supports 8 players.
Conspiracy supports 3–4 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 Conspiracy is 90 minutes. This is the publisher’s estimate for a full game. The actual duration depends on the group, the player count and familiarity with the rules: first sessions usually run longer, while experienced groups often finish faster. Setup and teaching time are not included in this estimate.
The catalogue lists Conspiracy for ages 10 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.
Conspiracy has a complexity rating of 1.9 out of 5 from BoardGameGeek players, which makes it a light game. The rating reflects how much rules knowledge, planning and decision-making a typical game demands. Expect a longer first teach for heavier games, and use a preparation guide before game night.
