Bean to Bar Chocolate
Skull is a 'poker-esque' bluffing card game where you have to guess the number of cards you can reveal without revealing a skull.
Each player plays a face-down card, then each player in turn adds one more card – until someone feels safe enough to state that he can turn a number of cards face up and get only roses.
If they show only roses, they win; if they reveal a skull, they lose, placing one of their cards out of play. Other players can challenge them, saying they can turn even more cards face up. The highest bidder must then turn that number of cards face up, starting with their own.
