Card games are the Games played with
a deck of 52 standard cards. The deck
consists of a fixed number of pieces
of printed cardboard known as cards.
The cards in a deck are identical in
size and shape. Each card has two sides,
the face and the back. The backs of the
cards in a deck are indistinguishable.
The faces of the cards in a deck may
all be unique, or may include duplicates,
depending on the game. In either case,
any card is readily identifiable by its
face. The set of cards that make up the
deck are known to all of the players
using that deck.
In addition to games that use the standard deck, there are also games that use some modification of the standard deck, for example excluding all cards of rank lower than some rank (e.g., a pinochle deck), or adding a special card, joker, to the standard deck. Many European regions have their own variants of the standard deck having different names and imagery for suits, or having a different set of ranks in the cards.
