A little like charades, Codenames is a social word game with a really simple premise. Two rival spymasters know the secret identities of 25 agents. Their teammates know the agents only by their codenames. The teams compete to see who can make contact with all of their agents first. Spymasters give one-word clues that can point to multiple words on the table. Their teammates try to guess words of their team colour while avoiding those that belong to the opposing team. All this while avoiding the 'assassin' words that will lead to the team losing immediately.
