Each participant gets four cards face up. Each player takes turns being the dealer. The dealer turns over a card from the deck. If the card they turn over matches the number of one of your cards you drink. The amount you drink is determined by the dealer. The dealer spins the quarter, and each player who had a matching card on that deal chugs the beer until the quarter falls to the table or floor. You play until the deck of cards is used up and then you start the next round with new cards. After a few rounds of this, everyone will be way too drunk to spin the quarter and will make for an entertaining drunken party.
