Team-based word association game — give one-word clues to reach your agents
Opens in a new tab · No downloads required
The smartest party word game available free in a browser. The Spymaster role rewards lateral thinking, while guessers reward confident teamwork — it plays differently every session.
The minimum is 4 players (2 per team, each with a Spymaster). codenames.game supports up to 16 players. The game also has a Duet mode for 2 players working cooperatively against a shared board.
Guessing wrong ends your team's turn immediately. If you hit a neutral word, it is revealed and play passes to the other team. If you hit an opponent's word, it counts for them — a costly mistake that can win them the game. Hitting the Assassin word is an instant loss.
codenames.game is the widely used free browser adaptation — it is not published by Czech Games Edition, but it faithfully replicates the board game rules and is the de facto standard for online play.
