Playing cards is the name for the 52 cards used in card games like poker, bridge, blackjack, solitaire and other games.
There are 52 basic cards in a deck (not including the jokers). These cards have a suit and a number (called the value or rank). There are 4 suits and 13 ranks in each suit.

The English pattern of cards is so widespread that it is often also known as the International or Anglo-American pattern.
