You and your partner are on a secret mission to a crowded city. Your objective: to contact 15 agents while avoiding a band of enemy assassins. You know the agents that your partner can contact safely. Your partner knows the agents you can contact safely. By giving each other one-word clues that can point to multiple words on the board, you try to find all the agents before your turns run out.
Codenames: Duet includes 400 new words so you do not need any other Codenames game to play. On the other hand, if you own the original Codenames, you can use the word cards from the two games interchangeably.
