The way we played it, you had to put at least one card down on your turn. So, if you didn’t have any of that card, you had to bluff. You could put as many cards down as you wanted. You had to state how many cards you were adding to the stack. It was funny when someone got called on their bluff, picked up the stack and looked at it, and then announced incredulously that everyone before them had been lying too.
