Codenames is a game for two teams. There is a grid of 25 words. Some of them are secretly assigned to the Red Team, some to the Blue Team. One player from each team is the Spymaster, and only Spymasters see which words belong to which team. Spymasters take turns giving clues to their teammates (Operatives), trying to lead them to guessing their team's words. The team that guesses all their words first wins the game.
