why do you have jokers in a pack of cards
The Joker is a playing card found in most modern card decks, as an addition to the standard four suits (clubs, diamonds, hearts, and spades). The Joker originated in the United States during the Civil War and was created as a trump card for the game of Euchre. It has since been adopted into many other card games, where it may function as a wild card. The card is unique in that it lacks an industry-wide standard appearance.
