Card counting is a strategy used primarily in blackjack to track the ratio of high to low-value cards left in a deck. It allows players to make informed decisions on when to bet higher or lower based on the likelihood of favorable cards being dealt.
However, the legality of card counting exists in a gray area. Technically, it’s not illegal as long as players don’t use external devices or software. Some casinos, however, reserve the right to refuse service to anyone. Let’s figure out why here.
Disrupts the Casino’s House Edge in Blackjack
Card counting, particularly in Blackjack, allows players to monitor the remaining deck for favorable cards. Players use this knowledge to make more informed betting decisions, increasing or decreasing their bets when they predict advantageous outcomes. While it doesn’t assure a win every time, card counting enhances the player’s odds of making successful plays when the deck is more likely to favor them.
Casinos rely on a house edge to remain profitable over time. This edge ensures that, on average, the house will win more often than the player. Card counting disrupts this balance by allowing skilled players to predict more favorable outcomes. When players can consistently turn the odds in their favor, the casino’s profit margins are affected, which is why they take card counting seriously.
Creates an Uneven Playing Field
Casinos are designed to offer games of chance where anyone, regardless of skill, has the opportunity to win. Card counting shifts this balance, making the game less about luck and more about skill for those who know how to use it effectively. Players who understand card counting can gain a distinct advantage, leaving those who rely on chance at a disadvantage.
This unequal playing field detracts from the fairness of casino games, which are supposed to be about luck and entertainment rather than strategy and skill. Card counting tilts that balance too far toward strategy. This can lead to frustration among casual players who feel they are at an unfair disadvantage.
Loss of Revenue
Casinos depend on a consistent flow of income, which largely comes from the predictable nature of their house edge. As stated, card counters can consistently beat this system and reduce the casino’s overall revenue when they enter the equation. A single skilled card counter may not make a noticeable dent in profits, but when several counters frequent the same establishment, the losses can add up over time.
Card counting often involves players increasing their bets when the count is in their favor. This means that, when done correctly, counters can win larger amounts during favorable moments. While most players win and lose small amounts over time, card counters can walk away with significant winnings, impacting the casino’s bottom line more drastically.
Unwanted Attention
Card counting also brings unwanted attention to the casino environment. Casinos thrive on offering an exciting and fair gaming experience where anyone can win big. If skilled card counters were allowed to dominate Blackjack tables, the perception of the game might shift. Word could spread that specific individuals are consistently winning, which could discourage casual players from participating.
Most casino patrons are there to have fun and test their luck. If the tables are dominated by players using card-counting strategies to win consistently, the atmosphere can quickly change. Casual players may feel outmatched and less inclined to play if they believe they’re up against professionals using strategies beyond their reach. This could lead to decreased player engagement and a loss of clientele.
Challenges in Maintaining Security and Control
Allowing card counting would put additional pressure on casino security and management. Casinos already employ various surveillance techniques to monitor players and ensure fair play, but card counting requires even more vigilance. Detecting it involves closely watching players’ betting patterns and behaviors, which can be resource-intensive for casino staff.
While card counting isn’t illegal, casinos consider it an unfair advantage and go to great lengths to spot potential counters. This typically requires a database shared between casinos like BOLOs (Be On the Lookouts), sophisticated surveillance equipment, and experienced staff who can identify and intervene when necessary. The resources needed to maintain this level of security can be costly, especially if card counting were allowed to continue unchecked.
Prevents Team Play Exploits
Card counting isn’t always done by individuals acting alone. In many cases, teams of players work together to exploit the system. One or more players will count cards at different tables, signaling others when the count is favorable. Once the count reaches a point where the odds are in their favor, a high-betting player joins the table and places larger bets based on the information provided. This coordinated effort significantly amplifies the advantage over the house.
Team play introduces a new level of complexity that casinos must monitor. A single card counter may be difficult enough to detect, but when a team works together, it becomes much harder to track their movements and behavior. Coordinated efforts make it easier for teams to evade detection, which can lead to even greater losses for the casino. Team card counting has been documented in famous cases, such as the MIT Blackjack Team, making casinos more wary of these tactics.
Final Thoughts
Most casinos have implemented strict policies against card counting to protect their interests and maintain a fair gaming environment for all. In other words, this response isn’t because card counting breaks any laws but rather because it disrupts the casino’s advantage.
