In the game, players split into two teams, with each team selecting a spymaster. The spymasters know the secret identities of the words on a 5x5 grid of cards, while the other players, known as field operatives, do not. The objective of "Codenames" is for the spymasters to give one-word clues that relate to multiple words on the grid, guiding their teammates to guess those words correctly. However, they must be careful, as giving a clue that leads to an opponent's word or the assassin card ends the game immediately. The team that correctly identifies all of their words first wins the game. "Codenames" is celebrated for its simplicity, replayability, and ability to accommodate large groups of players. It encourages creativity, strategic thinking, and communication, making it a hit at parties and game nights. The game has also spawned numerous variations and expansions, providing players with even more opportunities for fun and entertainment.
