A classical set of card consists 52 unique cards, categorized by suit and by rank. The four suits of the french deck are hearts (♥), spades (♠), clubs (♣), and diamonds (♦). The ranks include Ace, the numbers two through ten, and the face cards Jack, Queen, and King. A joker or two may or not be present. These cards are used for various games, such as solitaire, poker, blackjack, etc. Often with gambling involved.
If characters are playing games with these cards, remember to tag the card faces accordingly. However, if the cards are too difficult to discern (for example they're very far away, stacked atop each other, depicted as loose scribbles, or are a nonstandard playing card), you don't need to tag the faces of those cards.
Additionally, if the actual playing card were played rather than being a simple prop or motif (i.e simply being held by the character), the tag card game is also applicable.
