Four cardboard coasters are all you get in this classic bluffing game. You place them face down one by one until someone challenges the table by declaring how many discs they can flip without hitting a skull. The tension comes when you look at your own hidden skull card and try to bait your friends into flipping it. If you guess wrong, you lose a card permanently from your hand. It is brutal because there is nowhere to hide when someone calls your bluff. The artwork is beautiful, but the game is literally just a few pieces of cardboard.
