Jacks and Queens are two of the four face CARDS in a standard deck of playing CARDS. They are usually represented by a royal figure, such as a king or queen, and are typically the highest-ranking CARDS in a game. Jacks and Queens are often used in card games, such as poker, blackjack, and bridge. The term 'Jacks and Queens' is also sometimes used to refer to a pair of CARDS that have the same rank, such as two Jacks or two Queens.
