Liar LiarA Hilarious Party Game for all ages. Who's the best LIAR in your friend group? Each round players share a short, personal statement relating to one of their topic cards. If you get the secret role of LIAR, you have to lie! Everybody else has to tell the truth. You win by identifying the liar, and by tricking your friends into thinking YOU are the liar. The player who wins the most rounds, wins the game.
