A deck of cards is a set of pieces of (traditionally) cardboard with a design on one side uniquely identifying the card, and on the other side a single design which is exactly the same for all cards in the deck.


Each of the elements of a deck of cards is a card.


The cards in a deck of cards are partitioned into a number of suits.

The traditional deck of cards that is usually discussed in the context of probability theory is divided into $4$ suits of $13$ cards each.

There may also be a small number (usually between $1$ and $3$) of extra cards, usually called jokers, which do not belong to any suit.

Older British books often refer to a deck of cards as a pack of cards, but the American English deck has effectively supplanted pack in Britain in recent decades.
