Blackjack, which is the most popular game in online casinos, is also known for its strategies. If you have been a casino player for some time you will know which strategies I am talking about here. Most of the casino strategies we follow today were originated from blackjack, including the famous card counting technique.

Card counting is a casino game strategy that involves predicting the next hand based on the remaining cards in a pool. In the streets of casinos, it is infamous as a cheating method of beating casinos. In most casinos, it is prohibited and you might be thrown out if you were found counting the cards. However, that doesn’t stop people from trying.

When it comes to playing at your home, you will be more than comfortable playing with just one of these, or you can use two of these. However, when it comes to casinos, we can see that the commonest number of decks is between 6 and 8 decks. We are talking about the standard decks, without using jokers in the process, of course. Blackjack comes in several variants. The game can be played with 1, 2, 4, 6, and 8 dec. But step into any casino, you will find at least five to eight decks of cards used in Blackjack game! Excluding jokers, each of these decks come with a standard 52 cards.

Card counting is not illegal. The worst a casino can do is throw you out from their premises or ban you for life. Now, if you are wondering whether card counting is actually possible, then the answer is yes. Although it takes years of practice and dedication to actually master this strategy, it is worth it.

Card counting is said to be a definite winning strategy for casino games, especially for blackjack. As per rough calculation, this technique is known to increase the player’s long-term winning odds by as much as 102% in a casino game. It doesn’t get better than this.

The things are, however, a little different when we talk about online gambling. Online casinos are more strict, based on automatic software and have less to no human intervention. So, the real question is whether card counting is possible in online blackjack or not.

## Card Counting in Online Casinos – Deck Penetration

The simple answer to your question is No. Card counting strategy is not at all usable in online blackjack or any other online casino games, including live casinos.

Deck penetration is a term closely related to the strategy of card counting. It refers to the percentage of cards that have been dealt at a given time. For example, if the dealer is in the half of a 6-deck game, that means you have 50% deck penetration. The deeper is the dealt set of cards, the higher is the penetration rate, the fewer cards are on the table, and the easier it is to make a count or a prediction of what the next card will be.

This is not possible in online casinos as the decks are automatically reshuffled after each hand in an **online blackjack** game, so it is impossible to count cards.

In live blackjack games, however, the cards are not shuffled after each hand, but the dealers are given instructions to shuffle the cards (deck) at close to 50% deck penetration to minimize the chances of anyone using card counting strategy. The number of cards on the table is way too high before 50% deck penetration to make any prediction for the next card. So, again it is impossible to count cards in live casino gaming.

There are different methods of card counting, out of which Knockout (KO) and Hi-Low are the two most famous ones. If you are planning to try your hand at this blackjack strategy, you should research about these two methods.

You’ve heard it time and time again – the fewer decks used in a game of blackjack, the better your odds.

Have you ever stopped to wonder why this is?

I got the inspiration to write this blog post after fielding a question from a buddy of mine who isn’t much of a gambler. He’s preparing to head to a bachelor party in Vegas and started to study blackjack. He noticed that everyone says “fewer decks is better,” but didn’t understand. After all, he said, the overall proportion of each rank of card is the same no matter how many decks are shuffled together.

This post is all about deck size and blackjack. We’ll cover why fewer decks is better, in detail, and include a little bit of math where appropriate.

**Fewer Decks = More Blackjacks**

The main reason we say that fewer decks is better for players is that, in each deck, exactly 1/13^{th} of all cards are Aces.

Yes, my friend was right, the initial proportions of card values to one another is equal no matter how many decks you play with. The reason you’ll be dealt more blackjacks with a smaller shoe is that the impact of removing a card from the game is greater in a game with fewer overall cards.

**Odds of Drawing Blackjack in a Single-Deck Game**

Let’s start by getting an idea of how often a player will draw blackjack in a single-deck game. To get to the probability of drawing a blackjack from a one-deck shoe, all you have to do is multiply the odds of drawing an Ace by the odds of drawing any card with a value of ten points. We know that a single deck of fifty-two cards contains four Aces and sixteen cards worth ten points – four tens, four Jacks, four Queens, and four Kings.

That means probability of drawing any Ace is 4/52, which we simplify to 1/13. Once you’ve drawn your Ace, the probability of then drawing any ten-point card is 16/51. Notice anything about those two numbers? 7bit no deposit. The first probability is based on a fifty-two card deck, but since you’ve already drawn a card, you have to now work out the probability of drawing one of sixteen ten-point cards from a deck of fifty-one.

This change in the divisor is the reason why a smaller number of decks is advantageous to the blackjack player, and gives the house a distinct disadvantage.

If you want to get an accurate number of the likelihood of drawing a blackjack from a single-deck shoe, you actually need to double your result, since you could technically get a blackjack with either a ten-point card OR an Ace at the start.

All told, the probability of drawing a blackjack from a single deck shoe is 4.83%. That’s the probability of drawing an Ace (1/13) multiplied by the probability of drawing any ten-point card (16/51), multiplied by two.

**Odds of Drawing Blackjack in a Two-Deck Game**

To give you an idea of the statistical difference between one and two decks, let’s look at the odds of drawing a blackjack when you start with 104 cards instead of 52.

The probability of drawing any Ace from a two-deck shoe is 8/104. The probability of then drawing any ten-point card from the same shoe is 32/103. When we multiply those two together, then double the result, we get 4.78%.

Odds of drawing a blackjack in a one-deck shoe = 4.83%. Odds of drawing a blackjack in a two-deck shoe = 4.78%. By adding a deck (and not changing any rules of the game), the casino has decreased your likelihood of drawing a blackjack by 0.05%. Remember, though, that each one of those lost blackjacks would have been a win under standard casino rules at a 3:2 payout. Losing those 3:2 payouts makes a big impact on your bottom line, and on the casino’s.

**Why do Double Downs Work Better with Fewer Decks?**

If you’re following along closely, you’ve probably already figured out that the same phenomenon that makes blackjacks more likely with fewer decks probably also affects the likelihood of a successful Double Down. If you double your initial hand (6 and 5), you’ll be more likely to draw a face card to form a total of 21 if the game uses fewer decks.

Here’s where things get tricky – don’t forget that your dealer also benefits from these changes at lower deck counts. It’s not just the player that has a shot at more blackjacks. The reason why this fact doesn’t impact the game as much as it might is that players win 3:2 for blackjack, while the house wins just even money. Also, the dealer can’t Double Down, while the player can. That additional doubled-win gives the player a bigger advantage than the dealer.

**Conclusion**

## Blackjack Double Down

All things being equal, meaning all rules being pretty much identical, a blackjack game that uses a smaller number of decks to build the shoe is advantageous for the player. One situation I’d warn blackjack players about – casinos that offer single-deck blackjack with a 6:5 or even 1:1 payout for player blackjack. The implication is that the casino is only willing to give you those improved single-deck odds in exchange for a reduced penalty at the point of player blackjack. In the case of games that don’t pay the traditional 3:2, don’t play them just because of the appeal of the single deck setup.
