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. With wild cards in play, the best possible hand is a five of a kind. The common rule in casino

), but any four same-suit cards with a bug make a flush, and a hand such as 7-Joker-5-4-3 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).

 and Omaha hold'em do not play well with wild cards. For some players, the problem with wild card games is that the winner is almost always the hand with the most wild cards, making the other cards irrelevant, and making skill less important.

Another issue with wild cards is that they distort the hand frequencies. In 5-card stud, the stronger hands are less frequent than the weaker hands; i.e., no pair is most common, followed by one pair, two pair, three of a kind, etc. When you add wild cards, the stronger hands gain frequency while the weaker hands lose frequency. For example, if you have a pair and a wild card, you will always choose three of a kind rather than two pair. This causes three of a kind to be more common than two pair. But if two pair ranks above three of a kind, the two pair will become more common.
