In the game of blackjack, “blackjack” refers to a hand that consists of an ace and a 10-valued card. This hand is the strongest hand in blackjack, and it automatically wins unless the dealer also has a blackjack. A blackjack pays out at a rate of 3 to 2, which means that a player who bets $10 and gets a blackjack will win $15 in addition to their original bet. Blackjacks are relatively rare in blackjack, as there are only four 10-valued cards in each deck (10, jack, queen, and king) and only one ace. Players can improve their chances of getting a blackjack by counting cards or using other strategies.
