Bluff or tell the truth, it's your choice - just as long as you don't lose! Swap and exchange cards to work out who's fibbing. If you wrongly call a bluff you must place that card face up in front of you for all the other players to see. As soon as a player has four of the same cards in front of them they lose. Good luck sniffing out the stink bug!
All cards are dealt to all players: take one card secretly and pass to the player on your left, basically like bluff. Avoid having four cards of the same card. A great bluff-game, not too good for families as there is only one loser!
