Wild card (cards)
A wild card in card games is one that may be used to represent any other playing card, sometimes with certain restrictions. These may be jokers, for example in Rummy games, or ordinary ranked and suited cards may be designated as wild cards such as the J♣ and 9♦ in Classic Brag or the "deuces wild" in Poker. A card that is not wild may be referred to as a natural card. Jokers, however, may also have other uses, such as being a permanent top trump.
In most cases, the wild card or cards must be agreed upon by all players before the cards are dealt and play commences. There are two common rules regarding wild cards: "fully wild" cards and the "bug".
A card that is fully wild can be designated by its holder as any card they choose with no restrictions. Under this rule, for example, a hand with any natural pair and a wild card becomes three of a kind.
Conversely, a bug is a limited wild. The common rule in casinos is that a wild card plays as a bug, which is given the rank of ace unless designating it as a different card would complete a straight, flush, or straight flush. Under this rule, a hand such as is just a pair of kings (with an ace kicker), but any four same-suit cards with a bug make a flush, and a hand such as makes a straight.
There is also a variation of the "Fully Wild" rule in which the wild card (in this instance they are usually jokers as there are traditionally only two and there is only one black and one red) can be any card of the suits matching the cards colour or current suit. For example, in a jokers wild game with these rules, the red joker could be used as any card of hearts or diamonds. Inversely, the black joker would be any card of clubs or spades.
Two exceptions to standard poker practice sometimes seen in home games are the double-ace flush rule, and the natural wins rule. The latter rule states that between hands that would otherwise tie, the hand with fewer wild cards wins. This is not common in casinos and should be treated as an exception to standard practice (as is the double-ace flush).
In some Austrian and South Tyrolean card games, one or more other cards may be used as wild cards, including the Weli, a special 6 of Bells, the 7 of Bells and 7 of Acorns. 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.
