Undercover
Same prompt. Secret roles.
Undercover is BluffUp’s spy-at-the-party mode. Civilians see the secret topic; undercover players only see the prompt and must blend in. Compare answers, vote for who seems off, then reveal the topic and spies.
Three ways to play
Classic
FreeEveryone answers the same prompt. Civilians know the secret topic; undercover players don't. Discuss, vote for suspicious players, then reveal.
Silent
FreeSame roles as Classic — no discussion phase. Answer, vote immediately, reveal.
Chaos
PremiumClassic flow plus a random twist each round — anonymous answers, speed round, lightning discussion, or reverse reveal.
