|Play Black Jack the way you normally would. You can have as many people as you want. If you want you can switch the dealer after each hand. The dealer has to stand on 17. You deal out two cards, the dealer deals to everybody and then him/herself leaving the first card down and the second one up, the dealer can look at the down card to see what he has.
After he goes through everyone, he deals out his card, but he has to stop at five cards. Anyway, whoever wins the hand does not have to drink, the other people have to drink however many they lose by.
If one of the players get 19 and the dealer gets 17 and another player gets 23 then the dealer drinks 2 sips and the other player drinks 4 sips etc...
