You and your partner are on a secret mission in a crowded city. Your objective is to contact 15 agents while avoiding a band of enemy assassins. You know which agents your partner can contact safely, and your partner knows which 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. However, if you own the original Codenames, you can use the word cards from both games interchangeably. This game is designed for 2 to 4 players, ages 10 and up, with a playtime of 15 to 30 minutes.
