Worlds most famous Game-- Playing cards

Worlds most famous game and without which not even single casino can sustain--- Playing Cards.

Playing cards were invented in Imperial China. They were found in China as early as the 9th century during the Tang dynasty  (618–907).

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.
