Trying to get rid of your "stockpile" of twenty cards is the object of the game while counting to 12 sounds super easy, but surprisingly this game seems to take forever. There are four piles that everyone builds in sequential order to twelve throughout the game. You may have up to four discard piles. During your turn you may use cards in your hand or discard pile.

Playing one round can take 30 minutes. Great game, but not my first pick.
