Why Single Deck Blackjack Games are Better for Players Why is a better for the player than a multiple deck game?
I must get asked that question at least once a week because the reason isn't very obvious to most.

Henry's website is But one of the major reasons is simply due to the fact that you will be dealt more blackjack hands in a single deck game compared to a multiple deck game.
Here's why this is so.
Suppose you took a single deck of cards, shuffled them, and then randomly picked one card.
What is the probability that you'll pick an ace?
Since there are four aces in a single deck of cards, the chance of drawing one of those aces is the ratio of 4 over 52.
Once you draw the ace, you are left with 51 cards to draw a ten-value card.
There are 16 ten-value cards in a deck of cards the four tens, jacks, queens and kings so the chance of drawing one is the ratio of 16 over 51.
If you multiply these two ratios, you will compute the probability of getting an ace followed by a ten-value card in a single deck to be 2.
However, you could have just as easily drawn the ten-value card first then the ace.
Therefore, the overall hand in a single deck game is twice 2.
This translates into one blackjack out of every 20.
For a 6-deck game the chance of drawing the ace as the first card is the ratio 24 over 312.
The chance of drawing the ten-value as the second card is the ratio 96 over 311.
Multiply the two ratios and you get 2.
Double it and you get 4.
In fact, if you do the math for 2, 4 and 8 decks here is what you'll calculate as the probability of getting a blackjack hand.
Single deck 1 in every 20.
Essentially the effect of removing a card from a single deck affects the percentages of the remaining cards to a much greater extent than in a multiple deck game.
This is another important point to remember when you playing blackjack.
Although getting more blackjacks is good for the player, it's even better when you get a blackjack and the dealer doesn't.
The exact probabilities of the dealer duplicating our blackjack in the same round are: Single deck 1 in every 27.
This makes a single deck game a much better game.
Another reason that a player's expectation is better in a single deck game is that a player is more likely to get a good hit when doubling down blackjack single deck game 10 or 11 compared to the same situation in a multiple deck game.
When you get a 10 or 11, it's usually made up of two undesirable small cards.
Their removal from the single deck increases our chances of getting a good hit.
Because of the dilution effect of so many more cards in multiple deck games, the probability of drawing a good card is less compared to the single deck game.
To summarize, single blackjack single deck game games are a better deal for blackjack single deck game players because: 1.
You will be dealt more blackjack hands 2.
The dealer is less likely to also have a blackjack hand and tie you, and 3.
You are more likely to draw a good card when you double down on 10 or 11.
Check first what the house pays for a blackjack because many casinos nowadays are paying only 6 to 5 for a blackjack rather than the traditional 3 to 2.
The 6 to 5 payoff is terrible and increases the house edge to over 1% against a player.
Therefore, single deck games are good but only when the house pays 3 to 2 for a blackjack.
If you plan to play in casinos, ensure that you are not breaking any local laws.
It's up to you to know the legality of your actions when you gamble.
