Blackjack is a casino card game in which players try to get closer to 21 than the dealer. It is a fast-paced and exciting game, but there are some things that you should know before you play. First, always be aware of the house edge – the higher the house edge, the less likely you are to win. Second, know what to do when you are dealt your cards – stand (or stay) if your total is higher than the dealer’s; hit if your total is lower than the dealer’s. Third, split 8s and aces whenever possible. This will usually give you a better chance of beating the dealer, and it will also reduce your losses if your hand is bad.
Some casinos use different rules for blackjack, so it is important to check the table rules before you start playing. For example, some tables only pay 3 to 2 for blackjacks while others pay 6 to 5. This makes a difference because it changes the odds of winning. Also, some casinos have more liberal rules on side bets, which can change the overall house edge of the game.
Card counting is another way to minimize the house edge, but it is difficult and requires practice. Basically, you count the number of high cards in the deck and subtract it from the number of low cards. This is called the running count, and it is usually calculated on a blackjack strategy chart. A more accurate way to count is to keep a true count, which takes into account the number of decks remaining in the shoe. This is more complex and requires a calculator.
The basic strategy chart is a great place to start for those new to the game. It will help you make the right decisions in most situations, but there are some exceptions. For instance, it is recommended to hit any total of 16 or more against the dealer’s up card, but you should only double down on hard totals of 11 or less.
Many blackjack games offer side bets, which can be fun and increase the excitement of the game. However, these bets come with a high house edge and should be avoided if you want to maintain the best odds of winning. It is also a good idea to set a budget for your blackjack sessions, so you don’t spend more than you can afford to lose. This is one of the most important responsible gambling tips and will improve your chances of winning.
