Blackjack players are always looking for an advantage. The easiest way is to find a game that pays 3:2 when a player is dealt a natural blackjack. The 6:5 blackjack game has a much higher house edge.
The house edge is even larger when a player doesn’t play with perfectbasic strategy. Casinos allow players to use a basic strategy card at the table. Unfortunately, not many players that could use the help from a blackjack card carry one.
There’s another way to find an edge when playing blackjack that’s often overlooked. It’s actually one of the easiest ways to decrease the house edge in a blackjack game. The fewer decks in play during a blackjack game, the lower the house edge. It’s that simple.
Blackjack House Edge By Number Of Decks
Playing a blackjack game with fewer decks single-handedly lower the house edge. This isn’t the only way to lower the house edge. There are plenty of blackjack rules that can make a game more player-friendly. If all rules are the same, the house edge in a blackjack game will be lower whether the casino pays 3:2, 6:5, or even money when a player is dealt a natural blackjack.
The House Advantage in Blackjack The house advantage, or house edge, is the percent of a player’s initial bet that the casino will expect to make in the long run. Flip it around, and it is the amount you would expect to lose.

Here are the different advantages for the casino using the blackjack house edge calculator from Wizard of Odds. Remember, the house edge is based on perfect basic strategy. Every misplayed hand increases the house edge for the casino.
- 1 Deck: 0.16%
- 2 Decks: 0.46%
- 4 Decks: 0.60%
- 6 Decks: 0.64%
- 8 Decks: 0.66%
As you can see the house edge for the casino increases when there are more cards in play. The same holds true for a game that pays 6:5 on a natural blackjack. Here’s the house edge for the same game with the adjusted payout for blackjack:
- 1 Deck: 1.55%
- 2 Decks: 1.83%
- 4 Decks: 1.96%
- 6 Decks: 1.99% (2% rounded up)
- 8 Decks: 2.019%
As you probably expected, the house edge is higher playing a 6:5 blackjack game. This example shows that the house edge is lower when the game has fewer decks in play.
Differences In Gameplay Depending On Deck Size
Single deck and double deck blackjack are often played differently than six and eight deck blackjack. The latter two games are the blackjack games players see most often in a casino. These games are dealt from a shoe or a continuous shuffle machine. Cards are dealt face up and the player uses hand signals to show the eye in the sky what play they want t make.
Single and double deck blackjack are considered “pitch” blackjack games. The dealer holds the cards and flings (or pitches) them face down to the players. That’s not the only difference from traditional blackjack games.
The player swipes the cards towards themselves to hit. If a player is dealt a blackjack, they flip the cards over to show the dealer. A player that wants to double or split they will flip the cards over and place the additional money next to the original wager.
When the player is ready to stay, the cards are placed under the wager. Don’t touch the money. Just slide the cards under the wager. The eye in the sky doesn’t like when you touch the money after placing a wager.
Blackjack players have different preferences. While most players seem to dislike any game with a continuous shuffle machine, others seem to have a preference for a shoe or pitch game.
Personally, I prefer the pitch blackjack games. The lower house edge is an obvious positive but that’s not the only reason. While I can’t really count cards, playing a game with fewer decks makes tracking cards a little easier. Lastly, the game is slower because the dealer has to shuffle or pick up a new deck every few games.

Blackjack is one of the most popular gambling card games. It is often hailed for being one of the few games where the player can get an edge over the house. This varies within the different variations and playing rules, but nonetheless, it is still one of more favorable games for the player. To get a picture of the probabilities behind Blackjack, the house edge, and how a player may favor their odds, we take a look at the mathematics of blackjack.
Click here if you are interested to know more about blackjack basics.
Basic Assumptions
Popular slot machines at casinos. To explain blackjack mathematics, we will look at a Blackjack game played with one standard deck.
- This deck pays 1:1 when a player beats the dealer
- 3:2 payed immediately when a player gets Blackjack (21 on the first 2 cards, unless the dealer also gets a Blackjack)
- Returns the bets when there is a “push” or a tie (when the dealer and player have the same numerical value in their hands)
- Dealer stands on 17.
- NOTE: this is the most basic example for illustration purposes and most casinos will have different rules which improve their edge, such as paying 6:5 for Blackjack.
The first and easiest probabilities to look at are those of “busting” after being dealt the first two cards. That is, asking for a third card and going over 21:
| Total Hand Value | Probability of Going Bust |
|---|---|
| 21 | 100% |
| 20 | 92% |
| 19 | 85% |
| 18 | 77% |
| 17 | 69% |
| 16 | 62% |
| 15 | 58% |
| 14 | 56% |
| 13 | 39% |
| 12 | 31% |
| 11 or less | 0% |
Likelihood of Hitting a Blackjack on the First 2 Cards
Here are the possible initial 2-card hands and their probability of being dealt:
| Two Card Combination | Frequency % | Description |
|---|---|---|
| Natural 21 Blackjack | 4.8% | An ace and a 10, J, Q, K |
| Hard Standing (17 – 20) | 30.0% | Two cards that sum 17-20, neither of which is an ace |
| Decision Hands (2-16) | 38.7% | Any hard hand (two non-ace cards) 16 or lower and any soft hand (at least one card is an ace and the other is 9 or lower) |
| No Bust | 26.5% | Any soft hand (Ace plus any card lower than ten) or hard hand (any non-ace cards) summing less than 11. |
| Total (all two card hands) | 100% |
How the House Improves its Edge at Blackjack
House Of Blackjack Game
Here is where the house can improve their edge by including more decks. The probability of hitting a Blackjack is reduced from 4.83% to 4.78%. Even though the proportion of cards remains the same when an additional deck is added (4/52 cards are aces in 1 deck = 8/104 cards are aces in 2 decks), the probability of getting a certain hand is not the same (think about removing 1 of four aces in the first deck vs removing 1 out of 8 aces in the case of two decks).
The house can also improve its edge by paying less whenever a player is dealt a Blackjack. While the likelihood of a payout is the same, the payout will be less and the house will increase its edge.
The third basic measure to understand is to look at what the dealer’s final hand will be. Given that the dealer in this case must hit on 16 and stand on 17, the only possible outcomes are that the dealer will have a hand between 17 and 21, or a bust in the following proportions:
| Dealer Final Hand | Probability of Getting Final Hand |
|---|---|
| Natural Blackjack | 4.82% |
| 21 (more than 2 cards) | 7.36% |
| 20 | 17.58% |
| 19 | 13.48% |
| 18 | 13.81% |
| 17 | 14.58% |
| Non-Bust (less than 21) | 71.63% |
| Bust (more than 21) | 28.37% |
Optimizing your Hand
Given this conclusion, and the knowledge of one of the cards that the dealer holds, a player’s own hand, and the payouts, a strategy can be developed to optimize a player’s earning at blackjack and reduce the house edge from about 8% to below 1%. Such a strategy was developed and is called the basic strategy:
| Dealer’s Up Card | Dealer’s Odds of Busting | Player Advantage Percentage |
|---|---|---|
| 2 | 35.30% | 9.8% |
| 3 | 37.56% | 13.4% |
| 4 | 40.28% | 18.0% |
| 5 | 42.89% | 23.2% |
| 6 | 42.08% | 23.9% |
| 7 | 25.99% | 14.3% |
| 8 | 23.86% | 5.4% |
| 9 | 23.34% | -4.3% |
| 10 | 21.43% | -16.9% |
| J | 21.43% | -16.9% |
| Q | 21.43% | -16.9% |
| K | 21.43% | -16.9% |
| A | 11.65% | -16.0% |
How does Card Counting Work?
House Of Blackjack 21
There are numerous websites where one can find the basic strategy when playing blackjack under different rules or numbers of decks. However, these do not take into consideration the changing odds after cards are dealt. For that, there is a system of card counting which was developed to increase the probability of winning. This strategy allows a player to gain enough of an edge to beat the house in the long run. But that is a subject for another blog post and is not particularly relevant to online gaming.
