Tutorial: How to Count Cards in Blackjack

According to mathematic terms, blackjack is the most profitable game the casino has to offer. In fact, this is the only game where the casino has no mathematical edge, and strong players can gain an edge by using card counts. The scientific theory of the game appeared in the United States in the early 1960s and has been all the time evolving since then, opening up new and new possibilities for players.

American universities hold conferences on blackjack periodicals are published, and numerous new books appear regularly (both for ordinary players and professionals). But, despite all this, the best online casinos for Canadians and Americans have a constant and tangible profit on blackjack. And the majority of players suffer losses. This is most likely due to the fact that not all players are able to count cards in blackjack correctly.

Rules of the Game

Depending on the rules of a particular casino, a standard deck of fifty-two cards is used (a game with one deck) in the game. However, 2 or even 8 standard decks can be used as well. This especially refers to multi-deck games.

The task of a blackjack player is to score twenty-one points or a number close to it; in this case, it is impossible to exceed 21 points (this is called “bust”). In the case of bust, a player loses unambiguously. Some online casinos introduce additional restrictions, so it is worth taking at least a quick glance at them before playing blackjack.

What Is Card Counting in Blackjack and How It Works?

Counting cards is one strategy that players can use to gain a one-point advantage over the dealer. In a typical blackjack game with one deck of cards, the house edge, which is the odds of winning the casino, is usually zero. This means that if you’ve chosen the right approach based on this method, then you will stay with your friends or win in the long run. This may not give absolute superiority. However, blackjack is the only card game where such an opportunity exists, and the gambling house will not have an edge.

This makes it easier and more profitable to count cards in the long run. This means exactly keeping the account of certain cards while the dealer issues cards from the deck. By keeping this count, you will roughly know which cards are most likely to fall next to you and the dealer. Such a small amount of information can tell you when to make a big bet and when the opposite approach will work best.

The card counting technique is based on probabilities and counting all the cards in the playing deck or decks. As the player sees a played (and subsequently discarded) card, one adds up the values โ€‹โ€‹of these cards. With the starting point equal to 0, this current account can take both negative and positive values. If the first hand from the deck has two (+1), nine (0), king (-1), ace (-1), ten (-1), and jack (-1), the current score will be -3 (minus three).

The higher the current score gets, the more low cards have been used, which means a higher percentage of high cards in the deck. Why is this so important? The basic strategy system is based on the assumption that the next card will be worth 10 points. If you know that the percentage of high cards in the deck is getting higher than usual, then the gambling strategy becomes more effective.
