Game played using many decks of playing cards, typically for entertainment or financial gain. In card games, each card is distinguishable from a single side. So that each player is aware only of the cards in his hand and not those in anyone else’s.

To participate in a game of cards, you’ll need a deck, a special set of playing cards designed for that game. Card decks have a predefined number of individual playing pieces made of paper or cardboard with designs on them. A deck of cards has uniform sizes and shapes.

A card’s face and its back are both visible. Each card’s back in a standard deck looks the same. Based on the rules of the game, the deck can contain unique card faces or duplicates. The appearance of a card can tell you what it is. Everyone who is using the same deck is familiar with the same set of cards.
