Wild card (cards)

Jokers are frequently used as wild cards, for example in games of the Rummy family.

Jokers, however, may also have other uses, such as being a permanent top trump in games like Euchre or 500, the odd one out in Old Maid, or high-value matching cards in Zwicker.

In the game of Perlaggen there are six or seven wild cards: four permanent Perlaggs - K or Maxl, 6 or Weli, 7 or Little Weli, the 7 of Bells or Bell-Spitz and 7 or Eichelspitz - as well as 3 "Trump Perlaggs" - the 7, Unter and Ober of Trumps.

Under this rule, for example, a hand with any natural pair and a wild card becomes three of a kind.

This is not common in casinos and should be treated as an exception to standard practice (as is the double-ace flush).
