Counting Cards for Blackjack Online
Author: Ben Morris | Last Updated: January 2025You can potentially use card counting in online blackjack to gain a valuable edge over the house. However, online casinos have a range of controls in place to prevent players from successfully counting cards, which makes it more difficult.
This guide breaks down the top three blackjack card counting systems and explains how to master them. We will discuss whether card counting in online blackjack works, and we will also highlight the best sites for anyone interested in playing live dealer blackjack.
Our Top Picks
Can You Count Cards in Live Dealer Blackjack?Can You Card Count Online Blackjack?
Yes, it is technically possible to count cards when playing live dealer blackjack at an online casino. You cannot count cards when playing virtual blackjack – which is powered by random number generators – so you will need to visit the live dealer section if you want to count cards.
However, counting cards in online blackjack is significantly harder than counting cards at a physical casino. Many brick-and-mortar casinos now use continuous shuffling machines to minimize the effectiveness of card counting. Pit bosses and other casino workers are also trained to identify and eject card counters. They look out for players that display unusual betting patterns and act accordingly.
When you play online, it is even easier for the site to monitor your bet sizes. If the software notices that you are engaging in unusual betting patterns – essentially ramping up the size of your bets when you feel the shoe is tilted in your favor – it can alert the staff, and you may find that your account is limited or suspended. Some online casinos also use continuous shuffling machines to deter live dealer blackjack card counting, so it is challenging.
How to Practice Counting Cards in Live Dealer BlackjackHow to Practice Counting Cards in Live Dealer Blackjack
If you would like to practice card counting at an online casino, simply head to the live dealer section and select a blackjack game. We have highlighted the top three blackjack card counting strategies below, so you can choose one and give it a go.
Here are some tips for anyone interested in counting cards at an online casino offering live dealer blackjack games:
- Start Simple: If you’re new to card counting, you might like to start with a simple approach such as the Hi-Lo system. Practice keeping a running count of the cards as they are dealt and adjust your bets accordingly. However, do not engage in especially wild fluctuations, which can cause the online casino to grow suspicious.
- Focus on Accuracy and Speed: Live dealer blackjack can unfold at a reasonably fast pace, so practice maintaining an accurate count while keeping up with the pace of the game.
- Use Card Counting Drills: There are lots of free online resources and apps that offer card counting drills and simulations to help you hone your skills. They can provide feedback on your accuracy and speed, helping you improve over time.
- Stay Disciplined: Successful card counting requires discipline and patience. Stick to your strategy and do not be discouraged by short-term losses or any fluctuations in the count.
- Learn Perfect Blackjack Strategy: Before you begin counting cards, make sure you know how to play blackjack with the optimal strategy. This requires you to know when to hit, stand, double down, split cards, or surrender.
Most Popular Blackjack Card Counting Systems
Card counting is a strategy that requires you to keep track of which cards have already been dealt. The basic idea is to assign a value to each card and then maintain a running tally, which is known as the count.
You can use this information to estimate the proportion of high-value and low-value cards remaining in the deck or the shoe (multiple decks). The goal is to significantly increase your bet size when the shoe tilts in your favor, at which point you will have an edge over the house.
There are a few different systems to consider:
- Hi-Lo System: This is one of the simplest and most widely used card counting strategies. You assign a value of +1 to cards 2-6, 0 to cards 7-9, and -1 to cards 10-Ace. Keep a running count of the cards as they are dealt and adjust your bets based on the count.
- Omega II System: This system is a more advanced card counting strategy than the Hi-Lo System. The Omega II System assigns +1 to cards 3, 4, 5, and 6, +2 to cards 2 and 7, +3 to cards 8, and -2 to cards 9, 10, and Aces.
- KO System: The Knock-Out System simplifies the Hi-Lo system by eliminating the need to convert the running count into a true count. It uses the same card values as the Hi-Lo system, but it does not require you to adjust the count based on the number of decks remaining in the shoe, so it is easier for casual players.
There are plenty of other card counting systems for blackjack, including the Griffin Ultimate. It’s super accurate, but it’s very difficult to keep up with. Most pro card counters can keep up with the calculations for a few hands, but it’s near impossible to use it for a full shoe without help from a computer.
What's the Best Blackjack Card Counting System?The Hi-Lo system is the most reliable in terms of sustainability. You can keep a running count for a long time, and you can gain between a 0.5% and 1.5% edge over the house.
