Are you a fan of blackjack? Do you enjoy playing this popular card game at casinos or online? If so, you might be wondering what the winning odds of blackjack are and how to improve your chances of beating the dealer. Well, you’re in luck because in this blog post I’m going to share with you some tips and tricks to help you win more often at blackjack.

First, let’s talk about the basics. Blackjack is a game where you and the dealer each get two cards, and you can either hit (get another card) or stand (keep your cards) until you reach a total value of 21 or as close as possible without going over. The dealer must follow certain rules, such as hitting on 16 or less and standing on 17 or more. The goal is to have a higher value than the dealer without busting (going over 21).

What Are the Winning Odds of Blackjack?

Well, it depends on several factors, such as the number of decks used, the rules of the game, and your strategy. In general, the more decks used, the lower your odds are because it makes it harder to count cards and predict what’s coming next.

The rules of the game also affect your odds, such as whether the dealer hits or stands on soft 17 (a hand with an ace that can be counted as 1 or 11), whether you can double down (double your bet and get one more card) or split (separate your cards into two hands) on any two cards or only certain ones, whether you can surrender (give up half your bet and end the round) or not, and so on. Your strategy also matters a lot because it determines how you play your cards based on the dealer’s up card and the probabilities of getting certain outcomes.

Online Blackjack Strategy

The best way to improve your odds is to use basic strategy, which is a set of rules that tells you the optimal way to play every possible hand based on mathematical calculations. You can find basic strategy charts online or in books that show you what to do for every combination of your cards and the dealer’s up card.

For example, if you have a 10 and a 6 and the dealer has a 7, basic strategy tells you to hit because you have a low chance of busting and a high chance of improving your hand. If you have a pair of 8s and the dealer has a 10, basic strategy tells you to split because you have a better chance of making two good hands than one bad one.

By following basic strategy, you can reduce the house edge (the advantage that the casino has over you) to as low as 0.5% in some games. That means that for every $100 you bet, you can expect to lose only $0.50 on average in the long run. Of course, this doesn’t mean that you will win every time or that you won’t have losing streaks, but it does mean that you will have better odds than if you play randomly or based on intuition.

Another way to improve your odds is to count cards, which is a technique that involves keeping track of the ratio of high cards (10s and aces) to low cards (2s through 6s) in the deck. The idea is that when there are more high cards than low cards left in the deck, you have an advantage over the dealer because you are more likely to get a blackjack (a 10 and an ace) or a high-value hand, while the dealer is more likely to bust.

When this happens, you can increase your bet size to take advantage of the favourable situation. Conversely, when there are more low cards than high cards left in the deck, you have a disadvantage because you are more likely to get a low-value hand or bust, while the dealer is more likely to get a good hand. When this happens, you can decrease your bet size or even stop playing until the deck becomes favourable again.


To sum up, blackjack is a fun and exciting game that can also be profitable if you know how to play it well. By using basic strategy and counting cards, you can increase your winning odds and beat the dealer more often. However, remember that blackjack is still a game of chance and that nothing is guaranteed in gambling. Always play responsibly and within your limits and enjoy the thrill of the game.
