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. Other players can then overbid him, saying they can turn even more cards face up. The highest bidder must then turn that number of cards face up, starting with his own. If he shows only roses, he wins; if he reveals a skull, he loses, placing one of his cards out of play. Two successful challenges wins the game
