What is this Fluxx you speak of?
It's a card game where the rules are Draw one, Play one.
Except some of the cards are extra rules and "goals" which means the criteria to win is always changing.
I highly recommend picking up the basic deck. it's great fun even if you only have two people but it's much better with more. I find 6 to be ideal though I've played a game that had 13 of us and it was amazing chaos.
