How to Play Undercover:

  1. Each player receives a secret word - most players get the same "civilian" word, while undercover players get a similar but different word.
  2. Players take turns describing their word without saying it directly.
  3. After each round, use our large, easy-to-tap buttons to vote on who you think is the undercover.
  4. The person with the most votes is eliminated.
  5. Game continues until either all undercover players are found (civilians win) or number of undercover equals civilians (undercover wins).

How to Play Mr White (Blank Card Mode):

  1. One or more players receive a blank card (Mr White) instead of the regular word.
  2. Mr White must listen to other players' descriptions and try to figure out the word without revealing they don't know it.
  3. Other players vote to eliminate the person they think is Mr White.
  4. If Mr White is eliminated before discovering the word, civilians win. If Mr White guesses correctly, they win!
  5. Mr White adds an extra layer of deception and challenge to the game.

Pro Tips:

  • Be Subtle: Avoid revealing whether you're a civilian, undercover, or Mr White in your descriptions!
  • Listen Carefully: Pay attention to subtle differences in how others describe their words - especially for Mr White detection
  • Mr White Strategy: If you're Mr White, listen for common themes and clues. Pay attention to what descriptions have in common!
