Learning card counting is an idea that is incredibly daunting to most blackjack players. The very idea of card counting has been mythologised in popular culture to the point where it feels like something only the most experienced blackjack players could learn. However, this is not the case, with single-card counting systems like K-O making card counting much easier. In this guide to how to use K-O in blackjack, we are going to explore how the method is used, how to learn it, and more.
What is K-O?
K-O is a single-card, balanced, card-counting system. Unlike more complex methods like the Hi-Lo card counting system, players do not need to work out their total compared to how many cards are in the deck. Instead, they simply keep a running total in their head, with each card being either worth plus one, minus one, or nothing.

How does K-O work?
K-O is an easy-to-understand system where players keep a running count of the deck’s value throughout the game. Each card is assigned a numerical value. If the deck’s overall value is positive, this is good for players, and if it is negative, it is bad for players.
- +1 Cards: Players can add +1 to their total whenever a card of seven or lower comes from the deck. Ace is not included in this.
- Neutral cards: Eights, nines, and Aces are neutral cards. When these come out, players do not add or subtract anything from their total.
- -1 Cards: Any card that is valued at ten or higher is considered a negative, and players should remove one from their total.
How Can I Use the K-O System when Playing Blackjack?
While the K-O system is one of the simplest card counting strategies to use, it can still be tricky for new players to learn. As such, it is essential that you practise using the system at home before you attempt to use it at a real-life casino.
Here is an example of the K-O system being used.
Cards: 7, 6, 10, K, A, 4, 5, 8, K
Running score: +1, +2, +1, +1, +2, +3, +3, +2 In this instance, the bulk of the cards that have come out have been positive, with only the two tens seeing you minus a score. When the score is positive, players can go with bigger bets because the number of higher-paying cards in the deck is greater. If the running total is negative, players should adopt a more cautious approach.

Can I Use K-O Playing Blackjack Online
No. Due to the nature of online blackjack, it is nearly impossible to use card counting techniques. This is because they use random number generators (RNGs) with multiple virtual decks.
Is it illegal to use the K-O system in Blackjack?
No. While card counting may be frowned upon in certain casinos, it is not illegal to use. Proving that someone is card counting is incredibly difficult, largely because it all takes place in a player’s head.
Popular culture always portrays card counting as something that will ensure you get a lifetime ban from a casino, but in reality, if you were winning often, a casino may just ask you to leave a certain table.
Conclusion: Is K-O Effective?
There are many misconceptions around using card counting systems, and one of the biggest is that they will guarantee you a win. This is not the case. All card counting systems, like K-O, do is help you minimise your potential losses.
Players should remember that no matter what tactic they use, they will never be able to defeat the house edge. As such, they should always ensure they are practising responsible gambling techniques and should seek support if they believe their gambling is becoming an issue.
