A Guide to Proficiency with the KO Card Counting System

The Knock Out System, sometimes called the KO count, is one of the most widely used systems for counting cards. Because it is so straightforward, it is frequently chosen by blackjack players who take the game for recreational purposes. Compared to other, more sophisticated procedures, it is generally acknowledged to have a lower level of accuracy. Nevertheless, it helps determine if the odds are favorable or unfavorable.

The KO System is a card counting system known for being the easiest to learn and utilize. Given that all you need to do is award a +1, -1, or 0 to each card dealt, this method is advised for those just starting out in the game. Using a system such as the Zen or Uston Advanced Count, in which you must assign three or more values and maintain running, accurate, and side counts, is significantly more complex than this.

On the other hand, the players were having trouble computing the actual count, and they continue to have this problem. Some people could be better at division, particularly in fractions, and have to figure out arithmetic while playing.

The KO card counting system was developed by Ken Fuchs and Olaf Vancura in 1998 after they saw this phenomenon. Comparable to the Hi/Lo method, the KO strategy requires you to assign a +1, -1, or 0; however, it differs from the Hi/Lo strategy in that you only need to look at the running count. There is a compelling reason to perform complex numerical computations because you do not have to determine the actual count.

Basics of the KO Card Counting System

By maintaining an accurate count during the game, players can discern if the shoe contains a heavy concentration of favorable or unfavorable cards. This is because all card-counting methods assign specific point values to the cards within the deck. That is, whether more high cards than low cards still need to be played. Although it operates the same way as other systems, such as the Hi-Lo count, the Knock Out System is considered an unbalanced counting system. This is in contrast to other conventional counting systems.

Basics of the KO System

The unequal distribution of cards with positive and negative values sets it apart from similar products. Under the KO couting, cards from two through six are counted as one point, while aces, tens, and face cards are given a point value of one point. According to this method, the value of an eight or a 9 equals zero, but a seven is also given a value of one point. When we count this way, we will eventually reach a running total of +4 per deck. This shows that we will ultimately reach this point.

These numbers are as follows: 

  • 2, 3, 4, 5, 6, 7 – +1 
  • 8, 9 – 0 
  • 10, J, Q, K, and A – -1

Keeping Running Count Using KO System

The most critical component of the KO card counting system is the ability to keep a running count, which also presents a potential risk. We use the term “pitfall” because it is possible for players to suffer significant losses if they are unable to comprehend the concept of a running count and become proficient in the ability to maintain a running count.

Keeping Running Count Using KO System

The regulations of the KO card counting system require players to provide a value of either +1, 0, or -1 to each card that is dealt at the blackjack table. Players are required to have this value assigned. All cards from two through seven are given a value of one, while the eights and nines are given a value of zero, and the tens through the ace are given a value of one; this is the way of counting cards.

To begin their running count, players must start with a count of zero in most other card-counting techniques. On the other hand, the starting count is determined by the number of decks utilized in the game when using the KO card counting system. Therefore, there is no longer a requirement to turn the running count into an accurate count because of this particular factor.


  • 4 – (4 times the number of decks that are currently being used)
  • In other words, if a person were to play blackjack with eight decks, they would start their running count at –28. In other words, (4 minus (4 x 8) = 4 minus 32 = -28

Now that we have gone over the fundamentals of this card-counting system, it is time to describe how it is utilized to compute the number of cards at the blackjack table. Because the only thing that players are required to do is maintain track of their running count, they only need to add or subtract one as the blackjack dealer deals cards to them.

To begin, players must establish the starting count based on the total number of decks. The next step is for them to determine whether they should add one to their running count whenever a 2, 3, 4, 5, 6, or 7 emerges, whether they should do nothing when an 8 or a 9 is dealt, or if they should deduct one whenever the dealer deals a 10, J, Q, K, or an ace.

If you play a game of blackjack with eight decks, for instance, this indicates that your starting count is -28 before you begin playing. After the dealer deals a pair of fives, you must add one to your running count. To put this into perspective, your current running count is -27. If the following card is a 3, you will add one more point to your running card, which will now be -26.

Because the KO system is a very straightforward way of card counting, it nevertheless requires significant expertise. Counting a full deck at home multiple times is a fantastic method to get started with this approach and is an excellent opportunity to practice it. After assigning the card values mentioned earlier, you will need to proceed through the deck until all 52 cards have been removed.
