A wild card is a card that can be used to represent some other card that a player needs to make up a poker hand, sometimes with some restrictions. This enables higher ranking hands to be made more often, which for some players makes the game more exciting. Since the introduction of the joker to the American deck in the 19th century, some poker games have been played with a wild joker. More often, however, some cards in the existing 52-card deck such as deuces (twos) or one-eyed jacks (jacks shown in profile with only one eye visible) are declared as wild. Some variants have wild cards that are determined in the course of the deal, and may change as more cards are dealt.
The index below includes both traditional poker variants with wild cards and invented variants (listed in italics). The columns show other categories to which some games also belong. See also the full index of poker variants, which includes an explanation of the categories.
