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
(poker and blackjack games at a casino). Playing cards are also used for illusions,
cardistry, building card structures, cartomancy and memory sport.
