A card game where the rules change as you play, and there isn't a goal until someone plays one. The goal changes just as often as the rules do, but most goals revolve around collecting particular "Keepers."

The Fluxx tag should be used on all Fluxx games, because they're so similar. This includes:

  1. Fluxx
  2. Cthulhu Fluxx
  3. Oz Fluxx
  4. Star Fluxx
  5. Pirate Fluxx
  6. Zombie Fluxx
  7. Monty Python Fluxx
  8. Martian Fluxx
  9. Family Fluxx
  10. Eco Fluxx
  11. Stoner Fluxx
  12. Regular Show Fluxx
  13. Monster Fluxx (Target Exclusive)

There are small variations between the versions of Fluxx (some have Creepers and others don't; only Cthulhu has the Doom Count), but they are quite small, so we only have one tag for this family of games.
