card (sports)

In sports, a card comprises a listing of the matches taking place in a title-match combat-sport event. Organizers divide overall cards into a main-event match and the undercard, which encompasses the rest of the matches. One can also further subdivide the undercard into midcard and lower card, according to the perceived importance of the matches. Promoters schedule matches to occur in ascending order of importance.

A card game is any game using playing cards as the primary device with which the game is played, be they traditional or game-specific. Countless card games exist, including families of related games (such as poker). A small number of card games played with traditional decks have formally standardized rules, but most are folk games whose rules vary by region, culture, and person.
