Firstly put the mug in the middle of the table and fill it to the top with beer. The game starts off with everyone getting one card. Once everyone has a card they all flip it over. Whoever has the highest card has to have a swig of their beer. If two people get the same card or their cards equal to the one number (eg. two people have 10 and Queen or Jack or King). If the cards are equal to each then there is a "Poker Playoff". This involves all of the people who have got the same cards. Play a game of poker and whoever loses that game of poker has to skull the mug in the middle of the table, if the person cannot finish that mug in one go then they have to refill the mug and try again until they skull the whole mug.
