Two rival spy teams are competing to see who can make contact with all of their agents first. Their spymasters know who all the agents are, but the teams only know their codenames. The spymasters will give one-word clues that relate to as many possible codenames of their own team as they can, and it's up to the teams to figure out the clues. Be careful - you might expose your world of espionage to a normal civilian, or worse yet, attract the attention of an assassin hot on the trail of both teams.
Codenames is a game for 2 to 8 (or more) spies ages 14 and up. Average playing time is 15 minutes.
