The ace in blackjack is the highest card on the player’s hand. When it is played, the dealer gives the player one additional card, rather than drawing from the deck.
The ace can greatly increase the player’s chances of winning, provided that it is placed in a position where it can be used to make aces or tens. In fact, depending on the number of decks used in a particular blackjack game, an ace can be worth anywhere from one to four points.
