Online blackjack is a popular game that offers players the chance to win big by using strategy and skill. One of the most effective strategies in blackjack is card counting, a technique that can give players a significant advantage over the house. While many believe that card counting is only possible in physical casinos, the truth is that it can also be successfully used in online blackjack games. In this article, we will teach you how to count cards like a pro in online blackjack.

Understanding Card Counting in Blackjack

Card counting is a strategy used by expert blackjack players to keep track of the cards that have been dealt and predict the likelihood of certain cards coming up. By keeping a mental tally of high and low cards, players can adjust their bets and playing decisions to maximize their chances of winning. The theory behind card counting is that when there are more high cards remaining in the deck, the player has a higher probability of getting blackjack or beating the dealer.

The High-Low Card Counting System

One of the most popular and effective card counting systems is the High-Low system. In this system, players assign a value of +1 to low cards (2-6), 0 to neutral cards (7-9), and -1 to high cards (10-Ace). By keeping a running count of these values as cards are dealt, players can determine the true count – the running count divided by the number of decks remaining in the shoe. A high true count indicates that the deck is favorable to the player, while a low true count favors the dealer.

Practicing Your Card Counting Skills

Before you start counting cards in online blackjack, it is essential to practice and hone your skills. There are many online resources and apps available that can help you improve your card counting abilities. Start by practicing with a single deck and gradually work your way up to multiple decks. Remember, the key to successful card counting is to maintain an accurate count while also playing your hands correctly.

Implementing Card Counting in Online Blackjack

When playing online blackjack, there are a few tips to keep in mind to effectively count cards. First, choose a game with fewer decks, as this will make it easier to keep track of the cards that have been dealt. Second, pay attention to the speed of the game and adjust your counting strategy accordingly. Finally, practice good bankroll management to ensure that you can take advantage of favorable situations when they arise.

Avoiding Detection

While card counting is not illegal, casinos frown upon players who use this strategy to gain an advantage. In online blackjack, it is essential to avoid detection by varying your bet sizes and playing patterns. Remember, the goal of card counting is not to win every hand but to increase your overall chances of coming out ahead in the long run.


Card counting in online blackjack can be a powerful tool for skilled players looking to increase their odds of winning. By understanding the basics of card counting, practicing diligently, and implementing your skills in online games, you can take your blackjack strategy to the next level. Remember, successful card counting requires patience, discipline, and a solid understanding of the game. So, the next time you sit down to play online blackjack, channel your inner pro and count cards like a true master.
