As with all versions of Fluxx, the rules start in Monster Fluxx as "Draw 1, Play 1", but players can play New Rule cards to change the rules of the game. Goal cards change the winning conditions, which are met by a player having certain Keeper cards in front of him. Players also play Action cards for one-time effects.
