Think Again! — a.k.a. C'est pas faux! (French for It's not false) — is a party trivia game in which all players know all the right answers – but where the right answer is not always what you are looking for.
Players take turns reading questions. After a player finishes reading a question; he reveals the back of the next question card; which indicates whether the other players need to answer correctly or incorrectly.
If the question card shows a green dot; the word Right or the genius (co-designer Bruno Cathala's face); players must give the correct answer. For the question What color are the Smurfs?; the first player to answer blue scores a point.
If the question card shows a red dot; the word Wrong or the dunce (co-designer Ludovic Maublanc's face); players must give a wrong answer. For the question above; the first player to answer any color EXCEPT blue scores a point.
If you speak too quickly and give a correct answer when an incorrect one is required (or vice versa); you lose 1 point. After each player has asked five questions; the player with the most points wins.
There are some absurd questions (e.g.: What colours are the letters of the alphabet?). It that case; the only correct answer is Think again.
Also include rule variants for play in teams over 3 rounds.
