Blackjack is a game of chance played using one or more 52-card decks. Each card has a value, ranging from 1 for the number cards to 10 for face cards and 11 for aces. Players compete against a dealer in an attempt to build hands that total as close to 21 as possible without going over. A player who beats the dealer’s hand is paid one times his or her wager. Ties are a push and the bet is returned to the player.
The game is usually played on a semi-circular table that can seat between five and seven players (or “spots”). Players choose their seats and place chips in the betting circle or box in front of them. If the table is full, it’s best to wait for an empty spot before joining a hand, unless a player’s coat or a stack of chips holds the space. Some casinos have a no-midshoe entry policy for Blackjack games, which means players must be seated before the dealer begins dealing.
Once the players have placed their bets, the dealer will deal two cards to each player. Then the players must decide whether to hit, stand, or double their bets depending on the situation.
If a player has a total of 21 on their first two cards, they have a natural or blackjack and win immediately. If the dealer also has a blackjack, the hand is a tie and bets are returned to their players. If the dealer’s initial two cards total 17 through 21, he or she must draw until the hand is closer to 21 than the player’s. If the dealer has a higher hand, he or she sweeps the player’s bet.
Several situations in blackjack may deviate from the procedures outlined above. For example, some casinos will offer a side bet called insurance, which pays if the dealer has an ace up and a player has an ace as well. This bet costs half of the original bet and pays 2-1 if the dealer has blackjack.
Another variation on blackjack is Spanish 21, which allows doubling after splitting and allows players to re-double after splits. In this game, the ten-value cards are removed from the shoe, which significantly reduces the house edge for the player. Players can find Spanish 21 games in many casino and some online gambling sites. While learning the rules of blackjack is simple, mastering the game requires a strong memory and knowledge of probability theory. In addition, many players choose to employ advanced strategies such as counting cards to gain a significant advantage over the dealer. These methods require extensive study and practice, but are worth the effort for those willing to make a commitment to success in blackjack.
