Counting cards when playing Blackjack can provide a player with information on how best to wager. If done correctly a player can get an advantage over the house which means more profits over time. It’s as simple as that. Counting cards is not illegal as long as external devices such as a smartphone are not used while at the tables.

Counting cards is not as difficult as you might think. Most people assume you have to remember every single card that has been played. Fortunately, that isn’t the case. Card Counter can teach you various counting systems but defaults to the “High-Lo Count” system that was created by Harvey Dubner in 1963. It is the most widely used counting system for both amateur and professional players because of its power and simplicity. You don’t have be a math genius to learn and use this system. All you have to do is use Card Counter to study, practice, and sharpen your skills.

The counting system works by keeping a running total in your head that tracks the ratio between high and low cards. The counting system will have a positive running count when the deck has more high cards than low cards. A deck that has more high cards than low cards is called a hot deck and offers the player several advantages. First, the player is more likely to get Blackjack or at least dealt a higher starting hand. Second, the dealer is more likely to bust which means the player wins. When a deck is hot the player should increase their bet as the chances for winning increases.
A cold deck means there are a higher number of low cards than high cards. The running count will be a negative number when this is the case. Based on this information the player should just bet the minimum and wait for the deck to get hot again.


The Hi-Lo counting system is the most popular counting system and the default in Card Counter (although you can change it in settings). Hi-Lo works by assigning each card a number value of +1, -1, or 0. For every card that is flipped up you add that value to your running count. Here are the card assignments for Hi-Lo:

  • Cards between 2-6 are +1
  • Cards between 7-9 are 0
  • Cards between 10-A are -1

For example, let’s say the following cards were dealt:
Blackjack Hand
The 5 adds +1 to the count, the 2 is +1, the King is -1, the 8 is 0, the 6 is +1, the Ace is -1, and the 3 is +1. Adding those numbers together would equal a count of 2.
The count carries over to the next deal unless the dealer shuffles to reset the count back to 0.


Card Counter scores as follows: A correct answer yields $1,000. If a correct answer is provided quickly, bonus points are awarded based on the time taken to answer. The maximum amount of bonus points you can earn is $1,000 for answering quickly. For every previous round you guessed correctly you get a multiplier bonus up to 5 times the round score. That means if you answer correctly and quick enough you get $2,000. If you correctly answered the last 5 rounds then you would get a 5x multiplier and earn $10,000 for that round. If the provided answer is incorrect, but the count is only 1 off from the correct answer you will receive $100 for the effort. If the provided answer is 2 away from the correct answer, you will receive $25.


Tutorial: 3 Rounds with count displayed on the card. Just add them to your running count and dial it in to get a perfect score.

Easy: 5 Rounds and the count has been removed from the card. The running count is always set at the start of each round. After this round you will have to remember the running count as it won’t be set for you.

Medium: 5 Rounds and the running count is no longer set at the start of each round. You will need to remember it and start with the count from the previous round because the controls will go back to 0. You’ll also notice more cards, faster deals, and a new blackjack simulation showing how a typical deal will look so you can learn to quickly scan a table.

Hard: 10 Rounds with more cards, faster deals, and faster flipping of cards after the deal. The pedals also will hide while the cards are dealing forcing you to keep the count in your head while you deal. If you can get perfect on this level then you are doing great and ready for the tables.”));

Expert: This level is the most difficult and puts your counting abilities to the test. Achieving perfect on Hard level is more than enough to have all the skills you need, but if you can get a perfect score on this level then you are truly a master at counting.

Challenge: Unlimited rounds to see how much money you can earn. Only Blackjack is dealt so you can really focus your skills while at the table. Each round will get harder by either getting faster or having another player join the table which means more cards. If you answer incorrectly then the game is over and you take your score. See how much money you can earn!


The home screen has poker chip buttons to display the Study guide, Play the Game, Show Leaderboards, and Show Awards. Game Settings are available at the top left of the screen and is where you can change the card counting rule system, toggle voice/sounds/music, enable help advice on wrong answers, and reset all settings. The default rule system is Hi-Lo which is recommended if you are just learning to count cards. If you are already trained on another system (KO for example) or if you want to input a different custom system then that is also an option.


The true count should be used in determining how much to bet. It is calculated by taking the running count and dividing it by the number of decks remaining in the shoe. For example, if the running count is 6 and there are an estimated 2 decks left in the shoe, then the true count is 6 / 2 = 3. Typically a bet factor is applied based on the true count and what you normally bet. For example, if you usually bet $10 then you would do the following:

True CountBet FactorAmount
111 x $10 = $10
2 – 322 x $10 = $20
4 – 533 x $10 = $30
6 – 744 x $10 = $40
8 or more55 x $10 = $50
