Counting cards is an in-depth method that is difficult to cover on a single page, but when you learn how to count cards in blackjack, you can gain an edge against the casino. Because blackjacks pay more than even money and you have the opportunity to double and split in favorable situations, if you can change the bet size based on the remaining cards in the single or multiple decks you can shift the house edge to your advantage when you play blackjack and other casino card games.

Almost anyone can learn to count cards. I won’t tell you it’s easy, but it’s probably not as hard as you think. Statistically, if more high cards remain in a deck than low cards, the edge moves toward the player. When the high cards have been played at a higher rate than low cards the edge is shifting toward the house. From the top of the deck or shoe, the house edge is strong.
Basic strategy counting systems only require the ability to add or subtract one at a time and keep the total in your head.
Here’s an example. If you start at zero (where many counts start) and the following hands are played, you end up with a count of +1 using the popular Hi Lo system.
When you learn how to count cards in blackjack, you can gain an edge against the casino.
In Hi Lo, all cards 6 and below are +1 and all cards 10 and higher (including aces) are -1. You see six +1 cards and 5 -1 cards, so the new count is +1.
If you can do that, you can learn how to count cards.
Card counting systems are generally put into groups depending on their supposed difficulty.
Some counts are harder than others, and if you can’t keep an accurate count you’ll lose the edge counting is supposed to give you.
You’re always better off playing a less effective system perfectly than a more advanced system with mistakes. Pick an effective system and master it. Don’t worry about finding the most powerful system known to man.
Each of the system summaries below includes a level. The level is simply the highest number you need to add or subtract from the count. A system that only adds or subtracts one is a level 1 system and a system that adds or subtracts two is a level 2 etc.
The Omega II system listed below uses an ace side count.

When it comes to counting cards, though it’s not illegal at the federal or state level, it is frowned upon by pit bosses at brick-and-mortar casinos. Back when card counting was a new concept, casinos lost a lot of money to it! Now they often have automatic shufflers which will shuffle cards between plays. You may also find yourself escorted off the premises if they suspect you of counting cards.
If you count cards when playing online, you don’t have to worry about pit bosses or consider the “eyes in the sky” tracking your strategy. It’s a more peaceful and less stressful experience. That said, legal online gambling sites in the USA use Random Number Generator technology which makes card counting impossible.

The pit boss will be happy every time you take insurance and perfect strategy requires avoiding it at all costs. No, card counting is different than basic strategy. Each will lower the house edge and benefit the player, but basic strategy is making the right choices based on the odds of each hand, without accounting for the cards remaining in the shoe.
