These drinking cards may look like a normal card game at first, but don't have any other similarities. The first player draws one card from the deck and reads whats written on the back. Every card has a different drinking rule that must be followed. You can see some example rules on the product photos. After the task is completed, the next player has to draw a card. Special "House Cards" are included that can be used to add your own house rule's into the mix and let you be a little creative. All cards are water- and alcoholproof which makes them durable and very easy to clean.
