How to Play Undercover (Who's the Spy)
- 1
The AI host secretly assigns words: most players get the same word (Civilians); one player gets a similar but different word (Undercover); optionally one player gets no word (Mr. White).
- 2
Starting with a random player, each person gives a one-sentence description of their word — without saying the word itself.
- 3
After everyone has described, players vote to eliminate the most suspicious player.
- 4
The eliminated player reveals their role and word.
- 5
Repeat until the Undercover is found or wins by surviving to the final 3.
Roles
Civilian
You have the common word. Describe it clearly enough to convince others you're not the spy — without making it obvious.
Undercover
Your word is close but different. Listen, blend in, and survive. Win by reaching the final 3.
Mr. White
You have no word at all. Bluff your way through — and win by guessing the Civilians' word when eliminated.
