Optional card on the decks that has a free value and a stick, so you can take the place of any other in a game. Although it does not have an assigned drawing, the custom is to use the image of a jester, since its original name in English is The jolly Joker ("The Jolly Jester"). It is called a wildcard to any element that can take any value of its type, or that easily accommodates in a group, even at their expense. See also King, Horse, Jack, Ace.
