Two rival spymasters face a grid of 25 word cards, each secretly hiding red agents, blue agents, innocent bystanders and one deadly assassin. The spymaster offers a single-word clue plus a number, and their team debates which words fit. Contact all of your agents first to win, but stumble onto the assassin and the game ends instantly, so every clue is a balancing act between ambition and caution.
Codenames plays with 2–8+ players in around 15 minutes, is light and easy to teach, and is recommended for ages 14+. Notable mechanics include team-based play, word association, deduction, communication limits and push-your-luck clue giving.
Designed by Vlaada Chvátil and published by Czech Games Edition in 2015, Codenames won the 2016 Spiel des Jahres and became a modern classic. Its success spawned stand-alone follow-ups such as Codenames: Pictures, which swaps words for images, and Codenames Duet, a cooperative take built for two players.
