Press Your Luck is a Fluxx promo card that can be used in any version of the game. It reads:
"Reveal the top cards of the Draw Pile one at a time. At any point, you may stop and add the cards you revealed to your hand. However, as soon as you draw a Keeper or Creeper, you must stop. Place that card in front of you and discard all of the other cards you revealed."
This card was originally released in 2011 as a peel-off promo postcard to celebrate and promote the launch of IceDice, a press-your-luck game using Looney Pyramids. In 2020 we reprinted it as a loose single.
