The Ace of Spades is the strongest card in a deck of cards. A complete set of playing cards is also called a deck. The cards in a deck are of the same shape and size. The cards are also used for fortune-telling and divination. Each card has two sides - face and back. The backs of the cards in the deck are the same and the cards are identified by their faces. For most modern games, the usual 52-card deck or its shortened version of 7 to Ace is used. Many games use special decks. The deck may also contain additional joker cards. The cards are divided into 4 suits - hearts, diamonds, spades and spades. Each suit consists of 13 cards, which, in order of increasing strength, are: 2, 3, 4, 5, 6, 7, 8, 9, 10, Jack, Queen, King, Ace. Depending on the rules of the game, the order may differ.
