A card combo is a combination of three cards in a card game, usually consisting of a tenace, a PAIR, and a MELD. A tenace is a holding of two cards in the same suit that are one rank apart, such as a king and a queen. A PAIR is two cards of the same rank, such as two jacks. A MELD is a set of three or more cards of the same rank, such as three aces. Together, these three cards form a powerful card combo that can be used to win a game.
