Fluxx: Star Fluxx
Like its brethren, Star Fluxx is the game of ever changing rules. It starts out as Draw 1, Play 1, but even that can change. When a Goal card is played, you can win by meeting the Goal, usually by having the correct Keeper cards in front of you. Action and Surprise cards help you to meet the Goal, or stop your oppenent. Creeper cards usually prevent you from winning, but are sometimes necessary to meet the Goal.
