A card​ game is defined as any game that uses playing cards as the primary means by which the game is played[1]. These cards can either be of a traditional design or specifically created for the game[1]. The variety of card games available is immense, including related game families like poker[1]. While some card games played with traditional decks have standardized rules and international tournaments, the rules for most are folk games that vary depending on region, culture, location, or even social circle[1]. Playing cards are made from specially prepared card stock, heavy paper, thin cardboard, plastic-coated paper, a cotton-paper blend, or thin plastic[4].
