There has never been a prosecution of all the players who have done this and even been caught. The issue only comes in the form of casino rules.

The process is relative to a player’s mindset and determination. If you put enough practice and dedication into any field, you’ll succeed. The card counting technique is certainly a craft, those beginning will start with a single deck game, for players online, the issue is that there is no clarification of how many decks are actually used.

So, let us first look at the pros and cons of the technique which give users a high advantage over the dealer and the casinos they play in.

Pros of Counting

  • It is a hard skill to learn, though everyone can do it, not everyone has the determination to practice.
  • To do it in casinos, card counters are now finding it increasingly difficult to get away with it whilst playing their games. The number caught has more than doubled since the 80s.
  • If caught by the staff running the table, you will be banned from returning to the casino.
  • Players online will have no idea of the number of decks being used, so a budding card counter may struggle at first until they can suss out a working method.

There are a number of things to weigh up, is it good, bad, worth the time, worth the rewards? Yes, it is hard at first, but what isn’t when it comes to learning a new skill. Is it easy once you know it? Well, the results speak for themselves.

How to Count Cards in Blackjack

The principle of the counting system is, of course, to gauge what cards remain within a deck whilst the game is played. The strategy of High-Low is a system that looks to subtract high cards from the lower ones through a points-based system.

Let’s discuss how the steps work for you to be able to become a true don of this deck counting system.

Step One: Points System

The Hi-Lo method is the easiest of all systems to practice. To start, the rule is to designate scores to the cards.

  • +1 point for cards 2 to 6
  • 0 points for cards 7 to 9
  • -1 point for 10 to Ace

This is the simplicity of the rules and as each one is dealt you will then begin to add the points or subtract to help know what is left in the deck’s shoe.

Step Two: Keeping Count

Examples of keeping count as the cards begin to be dealt from the shoe.

Game 1:

  • Player 1: 2 of Hearts and an Ace = 0 points
  • Player 2: Jack of Clubs and 10 of Clubs = -2 points
  • Player 3: 7 of Hearts and 3 of Spades = +1 point
  • Dealer: 6 of Diamonds = +1 point

The total of this round would be a score of zero points.

Game 2:

  • Player 1: Ace and 3 of Hearts = 0 points
  • Player 2: King of Diamonds and 5 of Diamonds = 0 points
  • Player 3: 7 of Hearts and 2 of Spades = +1 point
  • Dealer: 8 of Clubs = 0 point

The total of this round would be a score of +1 point

Game 3: With players hitting

  • Player 1: Ace and 3 of Hearts and a 9 of Clubs = 0 points
  • Player 2: King of Diamonds and 5 of Diamonds and 6 of Diamonds = +1 point
  • Player 3: 7 of Hearts and 2 of Spades and a 10 of Spades = 0 point
  • Dealer: 8 of Clubs and a Jack of Spades and a 6 of Spades = 0 point

The total of this round would be a score of +1 point

The pattern of play does this for every round and for every game until the cards are shuffled. This is why many will play and bet through single-deck games if the option of the table is clear that 52 cards will be used.

Step Three: Calculations

In order for casinos to stop counter for playing games like this, they add multiple decks, which as you can imagine, would require a longer time to learn and therefore pick up a more difficult technique.

In order to retain an edge over the house, the counter can use the ‘True Count’ approach. Having a score of +5 with 6 decks remaining in a game poses something totally different if there was only 1 deck remaining.

There are two instances for the ‘True Count’ to become a necessity.

  1. If there was 1 less high card per deck, there would be no advantage, the number of high cards bears no importance but it’s the concentration of them in relation to the low numbers.
  2. If in a game your count is +5 and only a single deck remained, we’d know that there are going to be five 10’s and Aces, this gives the player the edge.

The True Count is, therefore, the Running Count divided by the Decks Remaining.

The Running Count is 10 and Decks Remaining is 5, the True Count score is 2 because of 10 ÷ 5 = 2.
If the Running Count is at -7 and Deck Remaining is 2, the True Count score is -3 because -7 ÷ 2 = -3.

This is a good way to keep on top of the scores as decks clear round after round. This is the most basic online technique, which will take time to master as each hand is dealt over a long game.

Step Three: Bet Changes

There are now two areas the player has to keep count of in order for them to gain advantages over the house. The bet changes come with the score of the True Count, the higher the score rises, the more you increase your blackjack bets. So, if the scores in the negative and the casino has the edge, perform low bets.

Card counting in a casino is by no means an easy task, but your time playing online can work if you simply use this method and start to practice the systems with a pen and paper to hand.

How can I practice counting cards by myself?

Part Two: Running Count

Focus on counting through a deck of cards with their points, you should read the end of the deck with a score of zero. If this is not the case, then something has gone wrong and try again. You need to start familiarizing yourself with how the cards become a whole new language, by this, you need to start reading cards not as their number or suit but as their points value.

Part Three: True Count

The old-school approach of this is to write numbers down on scrap pieces of paper and to draw them from a hat and learn to start dividing the results by six, assuming we are practicing for a 6 deck game, you can alternate relative to the number of decks you wish to learn.

Is the movie 21 based on a true story?

Before you take on the house and have your cards dealt, you may want to watch the movie 21. One of the best blackjack related movies made with the game being the central focus.

With the skills acquired, they took millions from Vegas casinos.
