Circle of Death :
1 deck of cards minus the jokers are spread in a circle on a table (or floor if you've had to use it for firewood). There's no break in the circle.*
Each person takes it in turn to pick one up and reveals it :
2-5 drink that many shots/fingers
6-10 distrubute shots/fingers out to friends in anyway desired
J thumbmaster - this person holds this card until another J is picked up, and he places his thumb on the table, the last person to do the same, has to do 2 fingers/shots
Q questionmaster, this person can ask anybody a question, and they have to reply with a relevant question. Again, this person holds the Q until another is picked up.
K "I have never..."
A down your drink - though the A of Spades means you can get somebody else to join you

* if by picking up a new card somebody breaks the circle of cards - he has to down his drink
There are loads of sub rules, e.g. no pointing, no swearing, no slamming drinks onto the table. It's pretty expandable.
