In this game, each player has a deck of 30 Animal cards consisting of 5 each of Cricket, Spider, Fish, Chicken, Rabbit, and the almighty Mascot Worker!
Players shuffle their deck and draw 5 hand cards at the beginning of each round. The start player will announce whether they will play with legs or wings in the current round by saying "I bet there are X (number of) Y (animals) with Z (amount of) legs (or wings) among all animals in all players' hand cards."
And players take turns to raise the bet by increasing X, Y (animals' hierarchy), or Z, OR they can call the previous player BLUFF!

Play smart with the information in your hand, and play cunning when you raise the bet. But beware, don't let the Mascot Workers fool you!

Why You Lying! Duel is a small box with 2 decks of cards for 2 players to enjoy. You can also combine it with the base game to have a epic 5-6 players bluffing war!
