Four of a kind, also known as quads, is a poker hand such as on the board , that contains all four cards of one rank and any other (unmatched) card.
Quads with higher-ranking cards defeat lower-ranking ones. In community-card games (such as Texas Hold 'em) or games with wildcards or multiple decks it is possible for two or more players to obtain the same quad; in this instance, the unmatched card acts as a kicker. If two hands have the same kicker, they tie and the pot is split.
In Texas Hold'em and Omaha, four of a kind defeats all full houses and loses to any straight flush.
