2-3 decks of cards
deal everyone 9 cards
put 3 face down without looking
put "best" 3 cards on top of face down ones (2, 10, Ace, King, etc)
2 plays on anything
7 reverses
8 skips
9 the next person plays a card under 9
10 "blows up" the pile. Then the cards are out of play. Can't play on a 2
4 of a kind also blow up the pile (can use 5, 6 etc if want)
If you can't play on card, you have to pick up the pile
The last one with cards is the Poo Head.
