It’s often not the rules or the components that make a game. With Skull, it’s the little noises. The tut of tongue against teeth. A soft sigh. A full-throated chuckle. Ambigous sounds uttered before a card gets flipped over and all hell breaks loose.
Skull is a bluffing game. Everyone starts with four cards , three showing flowers and one a skull. You place one face down, maybe more. Then you start wagering with other players to see how many flowers you think you can flip.
