A playing car is a piece of specially prepared heavy paper or thin card, figured with distinguishing motifs and used as one of a set for playing card games. Playing cards are typically palm-sized for convenient handling and since the mid 20th century have sometimes been manufactured from plastic. A complete set of cards is called a pack or deck. A deck of cards may be used for playing a great variety of card games, some of which may also incorporate gambling. Because playing cards are both standardized and commonly available, they are often adapted for other uses, such as magic tricks, cartomancy, encryption, boardgames, or building a house of cards. The first ever printed cards were developed and crafted in Dresden, Germany.
