One word is dealt to the table and everyone knows it — except one player. In turn, you each say a one-word clue about it. Too obvious and the agent learns the word; too vague and the table thinks you are the agent. Then everyone votes, one player is eliminated and their role is revealed.
The agent does not know the word but listens: after a few clues they have to guess the subject and say something that fits the same mood. The civilians have it no easier — a clean clue hands the word straight to the agent.
4 to 10 players. A match takes about 10 minutes. Clues are spoken, so the table needs to be able to talk; playing remotely, the built-in voice channel covers that.
