You'll need a deck of cards with all 8s, 9s and the red 10 tens removed, people, and the ever-important beer. The buzz factor starts out low, but with lots of people, dealing last can be dangerous at best. The game is played just like BlackJack but to 7.5 points. Deal will go from highest draw to lowest. Dealer takes deck, deals one card face down to first player, one card face down to self.
Player looks at card, then bets any amount of beer, a large shot glass is usually a good limit.
Player keeps first card face down, and can take as many hits as he wants. If he goes over 7.5, he must announce that fact, and then drink the bet. If not, when he stops, dealer turns over his card, and then hits until he thinks he has the player beat. If dealer busts, he drinks the bet. When the dealer is satisfied with his hand, the player turns over his card.
