This game involves two-sided cards. Players place cards on one of three piles, adding a card that is exactly one more or less than the top card of the destination pile. If this is not possible then the player may courageously flip the top card to its other side. If the other side can be played on legally, play continues normally. Otherwise the player must take an entire pile of cards into his hand. The first player to run out of cards wins.
