A playing card is a piece of specially prepared heavy paper, thin cardboard, plastic-coated paper, cotton-paper blend, or thin plastic, marked with distinguishing motifs and used as one of a set for playing card games. Playing cards are typically palm-sized for convenient handling. A complete set of cards is called a pack (UK English), deck (US English), or set (Universal), and the subset of cards held at one time by a player during a game is commonly called a hand. A pack of cards may be used for playing a variety of card games, with varying elements of skill and chance, some of which are played for money. Playing cards are also used for illusions, cardistry, building card structures, cartomancy and memory sport. The front (or “face”) of each card carries markings that distinguish it from the other cards in the pack and determine its use under the rules of the game being played. The back of each card is identical for all cards in any particular pack, and usually of a single colour or formalized design. Usually every card will be smooth; however, some packs have braille to allow blind people to read the card number and suit. The backs of playing cards are sometimes used for advertising. For most games, the cards are assembled into a pack, and their order is randomized by shuffling. Dedicated deck card games have sets that are used only for a specific game. The cards described in this article are used for many games and share a common origin stemming from the standards set in Mamluk Egypt. These sets divide their cards into four suits each consisting of three face cards and numbered or “pip” cards.
