A 52-card deck is a standard set of playing cards used in many card games. It consists of four suits: hearts, diamonds, clubs, and spades. Each suit contains 13 cards, including numbered cards from 2 to 10, and face cards: a jack, queen, and king, along with an ace. The 52-card deck is commonly used in games like poker, bridge, and solitaire. In addition to the main cards, decks often include two jokers, which can be used as wild cards in some games. The design and artwork of the cards can vary, but the structure remains consistent.
