 Black cards: can be used to add or subtract as you wish, you have to speak out while playing the card. 
 Double-order card: If a player plays the double-order card, it means the players have to complete 24 slices to win the round. 
 On the house card: If a player plays this card, it means they have a special coupon for that round.
