Blackjack is one of the most popular casino games in the world. The game has simple rules that can be learned easily, and the house edge can be brought down to less than 2% with proper strategy. The game can be played with a variety of side bets, as well. These side bets can increase the payouts and odds of winning. But before you can make these secondary bets, you must know basic blackjack strategy.

To play blackjack, the dealer will deal each player two cards face up. Players can then choose to hit and receive additional cards or stand, depending on predetermined rules. When a player has a higher hand value than the dealer, they win and are paid an amount equal to their original wager. If the dealer has a blackjack, all other hands lose. If a player has a blackjack and the dealer does not, it is a push (a tie), and the player gets their original bet back.

Counting cards is an extremely useful technique for blackjack, but it’s important to remember that it is only part of the overall game strategy. There are many other factors to consider, including the number of decks in use and the strength of the dealer’s up card. For example, it makes more sense to double down in a single-deck game, where the odds of getting a 10-value card are much higher, than in a game with multiple decks.

The decision to hit in blackjack is generally based on the dealer’s up card and whether your starting cards have a high value, such as a pair of tens. A good rule of thumb is to hit when your cards are worth 12-16 and the dealer has a weak card, like a five or six.

Another way to increase your chances of winning at blackjack is to split pairs, such as two threes or two nines. This increases the value of each hand and the probability that you will get a blackjack, which is paid at 6 to 5 or 3 to 2. However, always be sure to follow the rules of the table when splitting, as some casinos don’t allow it.

To avoid making costly mistakes, it is a good idea to practice your strategy at home before playing for real money. In addition, effective bankroll management is essential to long-term success in any casino game. Players should determine in advance how much they are willing to risk per hand and stick to it. This will prevent them from making emotional decisions that could result in financial strain.
