Card counting is a popular strategy used by blackjack players to try and gain an edge over the casino. While many people believe this technique is illegal, the truth is that it’s not against the law.
Card counting is simply a mental strategy that players use to track cards and adjust their bets based on the likelihood of certain cards being dealt.
However, despite its legality, casinos strongly discourage card counting and have the right to take action if they suspect a player is using this method. This could include banning the player from the casino, denying service, or even sharing the player’s information with other casinos.
What is card counting
Card counting is a technique used primarily in blackjack to track the ratio of high to low cards remaining in the deck. Players assign values to the cards dealt, typically +1 for low cards (2-6) and -1 for high cards (10-Ace), and maintain a running count to estimate the remaining deck’s composition.
The goal is to try and determine when the deck is in the player’s favour, allowing them to adjust their bets accordingly. While card counting is a legal mental strategy, it’s frowned upon by casinos, which may take action against players who use it.
How does counting cards work
Card counting involves tracking the ratio of high and low cards remaining in the deck. Here’s a simple step-by-step guide that I’ve put together:
- Assign values: Low cards (2-6) are given +1, high cards (10-Ace) are -1, and 7-9 are neutral (0).
- Keep a running count: Add or subtract the values as each card is dealt.
- Calculate the true count: Divide the running count by the number of decks left to get the “true count,” which reflects the actual advantage.
- Adjust bets: Bet higher when the count is in your favour and lower when it’s not.
Why shouldn’t you count cards at a casino?
While card counting can offer a small advantage, it does also come with significant risks. Casinos actively monitor for card counters and take immediate action to prevent players from gaining an edge at the table. The consequences of using this strategy can range from being banned to financial loss and even legal complications.
#1 It can get you banned
Casinos have the right to ban any player suspected of counting cards. If caught, you’ll likely be asked to leave, and your access to the casino, and potentially others in the area, can be permanently revoked. Casinos take such behaviour seriously to protect their business.
#2 There are more cons than pros
Although card counting can slightly shift the odds in your favour, it’s not guaranteed to lead to significant winnings. The time, effort, and stress involved often outweigh the small potential gain, making the overall experience less enjoyable and profitable than it seems.
#3 Legal Issues
Card counting itself is not illegal, but using devices or teams to enhance the process can lead to legal troubles. Casinos are private property, and they can eject you for any reason, including card counting. In some cases, returning after being banned can result in trespassing charges.
#4 Disguising the Strategy
To avoid detection, card counters must maintain a calm, unsuspecting demeanour at all times. This can be exhausting, as you’re forced to constantly monitor your behaviour while focusing on counting. Failing to do so effectively increases your chances of getting caught, so it’s not really worth it.
#5 Increased Risk of Losing
Card counting doesn’t guarantee profits. Many players still experience losses, especially if they don’t fully master the technique or if the casino takes measures like shuffling more frequently. The house still holds a significant edge, and inconsistent outcomes are often common.
FAQ
Is counting cards ethical?
Card counting is often seen as ethically neutral. It’s a skill-based strategy that doesn’t involve cheating or breaking laws. However, casinos view it negatively because it undermines their profits. While it may be fair game for players, the ethics depend on one’s perspective.
Why is counting cards banned at casinos?
Casinos ban card counting because it gives skilled players a small advantage, reducing the house edge. Although not illegal, it disrupts the casino’s business model. As private establishments, casinos reserve the right to refuse service to anyone suspected of using this strategy.
Are there professional card counters?
Yes, some players have mastered card counting professionally, often forming teams to increase their odds. Famous examples include the MIT Blackjack Team. However, professional card counters face constant risks, including being banned from multiple casinos, making it a challenging and almost impossible career path.
Is counting cards illegal in vegas?
Card counting is not illegal in Las Vegas, Nevada or anywhere else in the U.S. However, casinos have the right to ban players suspected of counting cards. They may also use security measures like shuffling more frequently or asking players to leave the premises.
