Technically, blackjack is a straightforward game. That said, as soon as you dig deeper than the basics, you’ll be dealing with terms like odds and different numerical probabilities. Without letting your intuition run the game, you should be prepared for all situations and make decisions based on your best blackjack odds.

After reading this guide, you will know the basics of the house edge and whether you can do something about it. We’ll go over five effective methods, give you practical tips on how you can apply them, and explain how they can affect the results. These efforts will help you develop a general understanding of what odds are and what makes them important.

In blackjack, the house edge or advantage is a statistical advantage of the casino over the player. A dealer of the casino is present at every blackjack table. Because the dealer is allowed to react last in a hand, the dealer has an edge over the player by seeing their.

The house advantage increases or decreases based on the rules set by the casino. For instance, a game with more decks in play will have a greater house advantage compared to one with less. Usually, players will opt for a casino offering the lowest house edge. The lowest house advantage in blackjack can go as low as 0.13%. Play Blackjack Online. It affects blackjack odds to a point where the probability of winning / house advantage is 0.5% or less. But one should know the rules of the game and how to play one’s cards correctly. If the player does not employ a specific-strategy and play impulsively, his hous-edge will be in favour of the casino in the range of 2-5%. In blackjack, the house edge or advantage is a statistical advantage of the casino over the player. A dealer of the casino is present at every blackjack table. Because the dealer is allowed to react last in a hand, the dealer has an edge over the player by seeing their cards, knowing their actions and potential mistakes.

What is the House Edge in Blackjack?

A lot of players are asking themselves: “What are the odds of winning blackjack?” and “How can I increase my odds of winning a blackjack hand?” These topics are essential to understand, especially for players who are just starting out.

Casinos have a mathematical advantage, otherwise referred to as the house edge. The reason is that players make a bet depending on the dealer’s first card. For example, players hit a card and bust about 28% of the time. And, even though the dealer goes bust as well, we will lose in this scenario. This number varies on the game-by-game basis, but it’s an inevitable situation that we have to play along with.

Despite not being able to eliminate the edge, there are effective ways to create more favorable blackjack odds. Right from the start, the house has a serious edge, but with the right plan, you’ll get that number down.

The Importance of Blackjack Odds

The effects of particular moves on the odds of winning blackjack have long been a topic of discussion. Namely, a mathematics professor and blackjack researcher, Edward O. Thorp, published a paper on favorable situations in certain games. These discoveries, such as specifically calculating the blackjack odds chart, have contributed greatly to the game we know today.

For example, it shows that the player’s probability to bust on an extra card starts from 0% (for the hard value of 11 or lower) and gradually increases – 31% (for 12), 39% (for 13) all the way to 92% (for 20). The importance of these values gets bigger when you consider how likely it is for the dealer to bust after the first card is revealed.

Many players make the mistake of predominantly fixating on their own hand, whereas the dealer’s odds are just as crucial. For example, it may seem that hitting on a hand value of 12 is what you should do. However, if the dealer also has a weak hand (i.e., a six), the advantage will be on their side, so it’s necessary to evaluate the probability of busting on both sides.

The odds of winning blackjack counting cards have a bad reputation, so it’s not always optimal to use a blackjack odds table. Instead, we have other methods to help you in the game.

House Edge of Different Variations of the Game

When the rules are slightly altered from the baseline, it affects the house edge and, by extension, your potential profits. Some of them can affect the outcome positively, whereas other variants will put the house at a further advantage.

The biggest variable in the game is how many decks are included. Generally, as you add another pack of cards, the casino benefits more. Casino blackjack odds are simple mathematics – the more cards are in the game, the lesser the chance of having a natural blackjack.

Also, the fact of whether you can double down or split makes a big difference for both the establishment and the person. The rule of thumb is that more options to choose from signify that your position will be looking up.

Here is a quick rundown of alternatives that play a significant role in the outcomes:

Always consider these factors before entering the game. It goes without saying that you want to avoid the unfavorable variants – those that add to the casino’s edge. There are many other variations affecting the blackjack house odds, but these ones are the most common.

Composition-Dependent Strategy

Blackjack basic strategy odds are decent, but this approach has some drawbacks. It only considers the total size of your hand regardless of what it is made up of. For example, 12 can be made up of 7+5, 8+4, or 10+2, and your actions depend on which composition you have at the time.

The composition-dependent strategy is a slight deviation, which works best in blackjack single deck odds since it makes the biggest impact on each hand.

16 Against a Dealer 10

You might be holding 16 made up of two cards (10+6 or 9+7), three cards (4+5+7), or even more, and it will make a difference on your blackjack casino odds and subsequent actions. Generally, 16 vs. 10 = Stand regardless of how many cards you have.

Exceptions for three cards:

  • 16 (6+6+4) vs 10 = Hit
  • 16 (7+6+3) vs 10 = Hit
  • 16 (8+6+2) vs 10 = Hit
  • 16 (9+6+A) vs 10 = Hit

Exceptions for four cards:

  • 16 (6+6+2+2) vs 10 = Hit
  • 16 (6+6+3+A) vs 10 = Hit
  • 16 (7+6+2+A) vs 10 = Hit
  • 16 (8+6+A+A) vs 10 = Hit
  • 16 (10+2+2+2) vs 10 = Hit

Since your hand contains smaller cards, there will be fewer of them in the pack. This slightly shifts the odds – rather than hit, you are advised to stand (but bear in mind those exceptions). Also, if you have 8+8, you should split (but remember about blackjack free bet odds).

12 Against a Dealer 4

Once again, you will receive different recommendations depending on what your 12 is made up of. If you have a ten-value card, you’re less likely to break with a hit. If you draw another card, you’re putting yourself at a slight advantage.

Two cards:

  • 12 (10+2) vs 4 = Hit
  • 9+3, 8+4, or 7+5 vs 4 = Stand
  • 12 (6+6) = Split

15 Against a Dealer 10

When you have an 8+7 combination, go for the hitting option rather than surrendering. However, it’s not the case for 10+5 or 9+6, where surrendering will be a slightly better move. While it doesn’t give you any guarantees, there is a higher probability of saving more money down the line.

Exceptions for three cards:

  • 15 (5+5+5) vs 10 = Stand
  • 15 (6+5+4) vs 10 = Stand
  • 15 (6+6+3) vs 10 = Stand

Exceptions for fours cards:

  • 5 (A+4+5+5) vs 10 = Stand
  • 15 (A+3+5+6) vs 10 = Stand
  • 15 (A+2+6+6) vs 10 = Stand

Here’s a more comprehensive table of the actions you should take during the game:

Casino Coupons

Another option for increasing odds in blackjack over house edge match is playing coupons. For example, you can bet $10 along with a coupon of the same amount. You can get paid double or lose only $10 of your own money, which is a good deal in either case.

We’ve already touched on the point that your odds of winning under normal circumstances are less than 50/50 considering the house edge. However, when you are paid double, you tip the scale and make the edge work in your favor.

There are also promo chips, which casinos hand out to encourage players to go back. One of the coupon types that is unique to blackjack are special bonuses that pay 2-1 on your first blackjack. Each casino has its own conditions to collect coupons and provide different instructions for using them.

Casino Complimentary Items

Comps are offered by the establishments as a reward. It can be a dinner, a hotel room, or even airfare with the goal of inviting more gambling activity from players. Your comps vary depending on how the casino perceives your contribution. Some advice to score better:

  • Play games with good odds because sometimes it can reach up to 1.5% for certain games.
  • Make your first bet slightly bigger – the supervisor will take notice of it.
  • Play at a crowded blackjack table to slow down the pace.
  • Adjust your bet size at the right time.

What are the odds for the blackjack game after you apply complimentary benefits? Let’s get into the details of how it works. Suppose the house edge is at 0.5%, and your award for playing is estimated at 0.3%. Some casinos offer double points at specific times on certain days of the week, which increases your comp percentage up to 0.6. Thus, you’ll be playing with a 0.1% edge over the casino.

By combining this method with other ones, you might be able to create the blackjack best odds, at least to the extent they can be.

Loss Rebate

What are the odds in blackjack when you successfully negotiate your gambling losses with the casino? The term “loss rebate” was introduced after Don Johnson was in the news with his successful act of social engineering. This case was unusual even for high-rolling gamblers, so it may not apply to everyone. Still, it’s worth taking a look at.

Don Johnson negotiated the following terms:

  • Substantial loss rebate – 20% on losses over $500,000 per day
  • Liberal house edge of 0.263%
  • Large wager size of $100,000
  • $50,000 per day of show up money
  • Entourage at the table

These conditions gave him better blackjack odds than card counting, so he didn’t even bother with cheating. He simply rebated at the exact time when his advantage over the casino was wearing out.

More often, casinos offer loss-based rebates, like 5% for $100,000 or 15% for $500,000. If the player loses big, then they cash out their rebate and move on to another place with a similar deal. If the player wins big, they take their winnings while they still have an advantage, which is what Don Johnson did.

Hand Interaction

Are blackjack odds better with more players? It might be with this method. If you’re shy, this method might not be for you as it’s based on tight interaction with other players at the table. What would you do if the other player had a pair of 7s against a 3, but had no money? Should you take one of their 7s? Or should you fill in for the other player that doubled down?

Let’s take an example when a player should double down but, for some reason, hesitates to put down more money. In this case, a more well-informed player could front the wager on the hesitating player’s behalf, possibly taking advantage of a good hand.

Casino Blackjack House Advantage

In another scenario, your odds when playing blackjack could be better if you give part of a bad hand to another player. Granted, it should be a beginner if you expect another player to accept the proposal, like having them front some cash on a losing hand. However, you could get some backlash because of that move. The unofficial code of conduct states that you play against the house, and you shouldn’t set others up for failure.

Most players understand that the casino holds an advantage in blackjack. This advantage is known as the house advantage or house edge, and is usually under 1% in most blackjack games, provided players play using the optimal basic strategy under the rules of the game they’re playing.

What does the house edge or advantage mean? It is an expression of how much of each unit wagered that the casino can expect to win on average. In other words, if the house advantage is 1% and you make bets of $100, you can expect the casino to win $1 for every bet you make over the long run. The results of doubling down, splits, blackjacks and everything else are included in that calculation.

Obviously, no bet in blackjack would cause you to lose exactly $1 on any given $100 bet. However, if you played tens of thousands of hands, or looked at the aggregated results of thousands of customers playing at the casino, you would see that the casino was coming out ahead by about that 1% margin. This assumes of course that everyone plays perfect basic strategy. The reality is that casinos make more than that because of players that don’t know about basic strategy or prefer to gamble and bet with their gut when they are feeling lucky.

Blackjack Rules and the House Edge

Not surprisingly, different blackjack rules can have an impact on the size of the house edge. Some rules variations are beneficial to the player, while others increase the casino’s advantage.

The following is a rundown of how different rule changes can affect the house advantage. Credit to The Wizard of Odds for their excellent analysis of how rules affect the casino’s advantage. All rule changes and their effects are rated against a typical game with the following rules: a blackjack game with an eight deck shoe, where the dealer stands on all 17s, the player may double on any two cards, the player can double down after splitting, and the maximum number of hands the player may split to is four. This game would have a house edge of about 0.45%.

Remember, the lower the house edge the better. So negative values below are better for the player while positive values are better for the casino.

Promotional Rules

Many promotional rules are sometimes offered which can offer a lot of help to the player. For instance, if blackjacks pay 2-1, the house advantage is reduced by 2.27%. The following are some possible promotional rules variations that help the player, along with the amount by which they reduce the house edge:

  • All blackjacks pay 2-1: -2.27%
  • Triple down: -1.64%
  • Five card Charlie: -1.46%
  • 2-1 on suited blackjacks: -0.57%
  • Six card Charlie: -0.16%
  • Seven card Charlie: -0.01%

Using Fewer Decks

Most players have heard that blackjack games with fewer decks are friendly to players, but you might be surprised to find that the differences between these games are relatively small. In fact, the player will see almost no advantage unless only one or two decks are being used. Here’s how reducing the number of decks affects the house advantage:

  • Six Decks: -0.02%
  • Five Decks: -0.03%
  • Four Decks: -0.06%
  • Two Decks: -0.19%
  • One Deck: -0.48%

Changing How the Dealer Plays

One of the biggest rules variations between various casino blackjack games is whether the dealer stands on all 17s, or hits on soft 17s (an Ace with another card or cards that total up to 17). The common rule of standing on all 17s is actually better for the player.

  • Dealer hits on soft 17: +0.22%

Player Options

Changing the options available to the player can also have an impact on the house edge. For instance, allowing surrender, the option to hand in your cards and get half your money back before the hand is played, reduces the house edge. Allowing this before the dealer checks for blackjack is known as early surrender, while allowing it only after the dealer has checked for blackjack (and not received one) is known as late surrender. This is the effect of some common player-friendly rule variations:

  • Early surrender against an Ace: -0.39%
  • Late surrender against an Ace: 0%
  • Early surrender against a Ten: -0.24%
  • Late surrender against a Ten: -0.07%
  • Hit after splitting Aces: -0.19%
  • Drawing a Ten after splitting Aces counts as blackjack: -0.19%

However, in most cases, casinos are more likely to eliminate player options rather than give players a helping hand. Here are some rule changes that limit what the player can do, and their associated increases in the house advantage.

  • Players can only split to three hands: +0.01%
  • Players can only split to two hands: +0.10%
  • Players may double down only on 9, 10 or 11: +0.09%
  • Players may not double down after splitting: +0.14%
  • Players may not split aces: +0.18%

Blackjack Short Pays

Perhaps the worst rules variation that can be found at casinos these days is the short pay blackjack. Traditionally blackjacks will pay 3-2 on your wager, meaning our example $100 bet wins $150. However, some casinos, particularly in Las Vegas, are now dealing blackjack games that offer less than this. While it may seem like a minor change, even a small reduction in the odds paid for a blackjack can have a huge impact on the house edge, turning what looks like a good blackjack game into a poor one. You should be particularly wary of games advertising “player friendly” rules such as single deck blackjack that only pay 6-5 or worse on a blackjack. Here’s how short paying blackjacks increases the house edge:

  • Blackjack Pays 7-5: +0.45%
  • Blackjack Pays 6-5: +1.39%
  • Blackjack Pays 1-1: +2.27%
