Blackjack is a gambling game in which the player competes against the dealer. The object of the game is to obtain a hand value as close to 21 as possible without exceeding it (busting). It is one of the most popular card games in casinos and is known for its high house edge.
The rules of blackjack are regulated by the gaming authorities at the casino where it is played. The basic strategy is to use a statistically optimal combination of cards, which minimizes the long-term house advantage while maximizing the player’s expected return.
Generally, the rules of blackjack involve players and the dealer making bets on each hand. Each player is dealt two cards, one face up and the other face down. The dealer acts last and must hit on 16 or less and stand on 17 through 21.
If a player holds a pair of aces, they can split the hand into two separate hands and place an additional bet on each hand. The split hands are then played independently of each other, and the bet on each is won or lost separately.
In some games, the dealers face up card is a burn card that can be turned into an insurance bet or surrendered to the player. This is an option that allows a player to increase their initial bet after seeing the dealer’s up card, and it increases their odds of winning.
This feature is especially useful in games where the dealer’s first card is an ace. Taking insurance gives you a chance to break even if the dealer has a ‘blackjack’, and it costs 50% of your bet amount in addition to the original bet.
The player may also choose to take a single bet instead of the standard double or split bets, but this is rare and increases the house edge by about 1.4%. In addition, some casinos have limits on the number of times that a player can split their aces.
Almost every blackjack variant has its own rules. Some variations, such as the Spanish shoe, pay even money on blackjacks and ties while increasing the house edge. Others, such as the double exposure game, have more liberal rules that attract new players.

Some people also employ a technique called “card counting,” which involves keeping track of the cards that have been dealt to the dealer and comparing them with those that have been played by the players.
