An ace is a playing card, die or domino with a single pip. In the standard French deck, an ace has a single suit symbol located in the middle of the card, sometimes large and decorated, especially in the case of the ace of spades. This embellishment on the ace of spades started when King James VI of Scotland and I of England required an insignia of the printing house to be printed on the ace of spades. This insignia was necessary for identifying the printing house and stamping it as having paid the new stamp tax. Although this requirement was abolished in 1960, the tradition has been kept by many card makers. In other countries the stamp and embellishments are usually found on ace cards; clubs in France, diamonds in Russia, and hearts in Genoa because they have the most blank space.

In playing cards, a suit is one of the categories into which the cards of a deck are divided. Most often, each card bears one of several pips (symbols) showing to which suit it belongs; the suit may alternatively or additionally be indicated by the color printed on the card. The rank for each card is determined by the number of pips on it, except on face cards. Ranking indicates which cards within a suit are better, higher or more valuable than others, whereas there is no order between the suits unless defined in the rules of a specific card game. In a single deck, there is exactly one card of any given rank in any given suit. A deck may include special cards that belong to no suit, often called jokers.
