Ace - Definition and Overview

This article is about the playing card. For alternate uses see Ace (disambiguation).

An ace is a playing card. In the standard deck, an ace has a single suit symbol (a heart, diamond, spade, or club) located in the center of the card, sometimes large and decorated, especially in the case of the ace of spades, which also often bears the name or emblem of the deck's printer. In most card games, aces have the highest value of all cards in a suit; in some, they have the lowest value, commonly representing a one. Many games, such as poker and blackjack, allow the player to choose whether the ace is used as a high or low card. When aces are high, spades are occasionally deemed to be trump cards, meaning that if it came down to a tie, the ace of spades would naturally win.
