Card counting is a controversial but fascinating strategy for blackjack that has been around for decades. Made famous by Hollywood and professional casino players, card counting is an approach that allows expert players a way to modify the house edge. Is card counting truly a game changer, or does the risk involved cancel out any conceivable advantage? Let’s examine a little closer what card counting does, how effective it is, and if it’s worth all the effort at casinos today.
How Card Counting Functions in Blackjack
Card counting is essentially a method used to track the ratio of high cards to low cards remaining in a shoe or deck. Since blackjack relies on a prearranged deck of cards rather than random spins or rolls, the players observing what has been played can estimate the likelihood of drawing advantageous cards.
The Fundamental Idea of Card Counting
The most widely used card counting system is the Hi-Lo system, which assigns a value to different cards as below:
- Low cards (2-6): +1
- Neutral cards (7-9): 0
- High cards (10, J, Q, K, A): -1
While the cards are being dealt, players mentally count. When the count is high and positive, it means there are a lot of high-value cards remaining in the deck, increasing the chances of blackjack or favorable hands. A negative count means a deck full of low-value cards, decreasing the chances of blackjack. Players increase their bets if the count is positive.
The Legality and Risks of Card Counting
Is Card Counting Illegal?
Unlike common myths, card counting is not illegal. There are no laws against players using psychological tricks to beat the house. However, casinos can exclude any player they believe is getting an unfair advantage. This means while you will not be criminalized for card counting, you may be excluded from a casino or even blacklisted from several clubs.
Casino Countermeasures Against Card Counters
Modern-day casinos employ several techniques to spot and counter card counting:
- Multiple Decks: Casinos today use six to eight decks in one shoe, so it is harder to know which cards are left.
- More Frequent Shuffling: Some shuffle more often, cutting off the count before it reaches its usefulness.
- Betting Pattern Monitoring: Strange bettors who tend to unexpectedly increase bets when they are ahead of the count may be noticed by pit bosses and surveillance teams.
- Facial Recognition and Player Tracking: Sophisticated surveillance can identify repeat offenders and known card counters.
Thanks to these countermeasures, card counting is far from being an infallible path to riches. Even the best players have a hard time winning reliably without getting caught and thrown out.
Does Card Counting Still Work Today?
The Effectiveness of Card Counting in Modern Casinos
While card counting was once extremely profitable, modern casino tactics have made it much harder to achieve long-term profits. Professional blackjack teams, like the famous MIT Blackjack Team, used to rake in millions using this method. Today, however, the use of automatic shufflers, multi-deck shoes, and casino heat security has reduced its effectiveness.
Is It Worth the Effort?
For recreational players, learning to card count can be a challenge and an enjoyable one, but maybe not the best way to make money. With the big risks of being banned and the practice that goes into becoming proficient at the skill, most gamblers prefer that simply playing basic strategy gives an important decrease in the house edge without the added stress.
Professional card counters typically work in groups and hide their play to avoid detection. Even under ideal conditions, however, winning a consistent profit using card counting requires self-discipline, a large bankroll, and thousands of practice sessions. Most players attempting it become frustrated and abandon the effort or are intimidated by casinos into abandoning it.
Other Ways to Win at Blackjack
Master Basic Strategy
Even without card counting, employing a solid blackjack basic strategy will cut the house edge to around 0.5%. Becoming proficient at the mathematical probabilities of when to hit, stand, double down, or split is one of the best ways to improve your chances of winning.
Choosing the Right Casino Games
Blackjack games are not created equal. Seek out:
- Tables with beneficial rules (for instance, 3:2 blackjack payouts as opposed to 6:5)
- Less Decks (double- or single-deck games are better for players)
- Rules Accepting Doubling Down More Hands
Getting the Most From Casino Promotions
Online casinos offer blackjack promotions, cashbacks, and VIP rewards that inflate your bankroll with no further risk. Crypto casinos, as well, typically present high roller promotions for blackjack players.
While card counting remains a viable strategy in theory, it is extremely difficult to execute in modern casinos. Most players will find that mastering basic strategy and managing their bankroll wisely offers a more sustainable and enjoyable blackjack experience. If you’re willing to put in the time, effort, and risk of being banned, card counting can still offer an edge — but for the vast majority of players, the risks outweigh the rewards.
