Complete Analysis of Blackjack Odds.

Casino Edge in Blackjack

All casino games have a certain percentage of casino advantage, which can be a major factor in determining whether a player decides to wager on a particular game.

Each variant of Blackjack has a different casino edge, which usually differs depending on the additional rules and the number of decks used in the game. The casino edge shows the advantage the casino has in playing the casino game. The lower the casino edge, the better it is for the player.

In the game of Blackjack, the dealer has the option of being the last to make a decision. So they can make decisions based on what the rest of the blackjack players are doing. This gives them a slight advantage.

The house advantage in blackjack will be higher if someone is a beginner and chooses not to use a blackjack optimal strategy. An exaggerated example of this would be someone who decides to take every card. If the player did this, the casino’s advantage would be 100%. This example is extreme, but it perfectly illustrates the importance of using some form of strategy. Every player who plays blackjack with a basic strategy can reduce the casino’s advantage to 0.5%.

Blackjack has one of the lowest percentages of casino advantage compared to all other casino games. Even without a basic strategy, the odds of winning at Blackjack are still lower than most casino games.

The Basics to Playing Blackjack of Blackjack

The main goal of the game is always to defeat the dealer, who, like the players, receives two cards.

  • The cards are evaluated as follows:
  • cards 2-10 are valued at face value;
  • K, Q, J bring 10 points each;
  • Ace gives from 1 to 11 points, at the player’s request.

It is worth noting that it is not always possible to collect 21 points at the first time. That’s why the winner of the game is the one who has the amount closest to this number, but does not exceed it. By the way, if a participant receives 22 or more points, he or she automatically loses, as this is a “surplus”. Luck can also smile if the dealer gets more than 22 points and the player gets less.

Both one and several decks are used in the game. As a rule, up to 6 decks of 52 cards are used.

How to Play Blackjack: Step-By-Step Instructions

Playing Blackjack requires some knowledge. Here is a step-by-step guide on what to do and how to play:

  1. The beginning.
    Each participant receives 2 cards. One dealer’s card is hidden.
  2. Distribution of additional cards.
    The player can pick up cards if he wishes and count cards. If the sum exceeds 21, he loses. In the example below, we can see the “surplus” or “overbuy”: 6+10+6 = 22.
  3. Counting cards.
    If at this stage someone has 21 points or close to this value, they are the winner. Winnings are awarded.
  4. Draw.
    When the number of points is the same, the bet is returned in the same amount. This outcome of the hand is called a “push”.
  5. A perfect hand.
    This is the name given to a combination that totals 21 points. In this case, the winnings are awarded at odds of 3 to 2 or 2 to 1. But you need lowest house edges for this.

The Main Stroke in Blackjack

You should also keep in mind the following moves.

StrokeStroke value
StandYou keep the hand value and end your turn in the round.
HitYou request another card from the deck to be added to your hand.
Split (if available)Creates two hands from a pair of cards of the same value. Another bet is required.
Double Down (if available)Requests one card and adds another bet equal to the original bet. The player’s turn ends when the third card is dealt.
Surrender (if applicable)Get rid of your hand and lose only half of your original bet.
Insurance (if applicable)A common additional bet in Blackjack when the dealer shows an ace. Typically, you’ll put half of your bet on the second bet. If the dealer has a Blackjack (21 of the first two cards), you get your insurance bet back, plus more money you wagered on the hand. If the dealer doesn’t have Blackjack, you lose your security bet. In essence, when you place a safety bet, you are betting that the dealer has Blackjack.

Blackjack Basic Strategy Odds

The odds of winning in blackjack can reach 42.22%. However, this does not mean that the casino will win 57.78% of the time. That is because there is a third possible outcome – a push. On average, 8.48% of blackjack games end in a push, which guarantees a 49.10% loss.

Blackjack Basic Strategy Odds.

These figures can fluctuate, and in some cases, significantly. It all depends on the variant of Blackjack, the rules for the player and dealer, and your playing style. For example, players who do not have a odds in blackjack with basic strategy. Their chances of winning at blackjack will be drastically reduced. It’s best to have a basic game strategy that will give you the best odds and an understanding of when to hit and when to stop.

Use the Blackjack Perfect Strategy ODDS to Win Tough Hands

In Blackjack, some hands are particularly difficult to win because the dealer and player have very little chance of winning. Although the dealer with the hole card is a useful tool, it can also cause problems.

That’s why our team of experts has selected the most difficult combinations of your hand and the dealer’s open card. We’re going to look at a few ways you can improve your chances of blackjack success by knowing the odds of winning for these hands:

15 against the dealer’s 10

The combination will give you a 22% chance of winning. Meanwhile, if you decide to stay, you will have the smallest advantage – a 23% chance of winning. You might as well take your chances and hit.

Hard 16

In Blackjack, a “hard 16” – is a hand that divides players into two camps. If the dealer shows a 7 or 8, you should call using basic strategy.

However. If the number 9 or 10 is dealt, you should consider folding. Although the possibility of being eliminated from the game is high, it is lower than with a dealer with 17 or more.

Low pairs

Let’s start with the easy ones. If you have a pair of fours, you should always split your bet on dealer 5 or 6. If you have a pair of fives, you should never split them. Conversely, a pair of aces should always be split.

More complicated decisions come when you get pairs of 2, 3 or 6. In these cases, you should split if the dealer shows a card between 2 and 6. You should also split 2 and 3 on the dealer’s 7. In any other situation, you should not split these cards.

If you don’t split, you should collect the twos, threes, and fours, regardless of the dealer’s card. Similarly, a pair of fives has the same reaction regardless of the dealer’s hand. However, here you should double your bet, as the odds are 20 in your favour when the dealer has 2-9. If you have a pair of sixes and the dealer has more than seven, you’ll want to call. But if the dealer has 6 or less, you should split the bet and hope that the dealer loses.

12 vs. 4 of a dealer

If the dealer is dealt a 4, there is a 40% chance of going bankrupt. This means that if you stay away, you will lose the hand in 60% of cases.

Your chances will increase if you decide to hit, because the probability of losing is 58%, and the probability of a push is 2%. Despite the slight advantage, we recommend staying away and waiting for the dealer to come.

12 versus the dealer’s 3

If you have 12 and the dealer has 3, you should bet once. The basic strategy is to stand here to receive any additional card added to your hand. The probability of a push here is 5%, which means that you won’t lose anything, but you won’t win either.

By the way, if you hit a 12 with two aces, the logic is different, as you should always split aces in Blackjack.

Table of Odds for the Player

While a player can playing basic strategy to reduce the casino’s advantage and get more favourable odds of winning at Blackjack, there is a way for land-based and online casinos to reduce the odds of players winning. This can be achieved by adding an extra deck to the game, adding certain restrictive game rules such as a ban on doubling after splitting, or even lowering the payout. All of this can significantly reduce the odds at the blackjack table. To do so, players need to understand blackjack probability and how it affects their chances of winning the game. Knowing blackjack probability will show players their edge in the game, which is crucial to reducing the risk of losing big money and maximising their profits.

We show the probability that you will pick one of the first two cards from the dealer to help our readers understand the game better. Below is a table of blackjack odds with examples of probabilities.

Dealer Payout Table

The chances of winning in Blackjack are higher for the dealer than for the players. This is possible due to the dealer’s ability to act as the latter, which is much easier as they make decisions based on their position. For example, if there is only one player at the table and they know that the player has twenty points, they can try to beat this score without fear of going bankrupt. However, the dealer’s chances of winning in Blackjack may vary depending on the internal rules of the game. For example, if the dealer is required to stand on a hand with a soft 17, this will affect many blackjack hands.

The Probability of Dealer Bankruptcy

Continuing with what we outlined in the previous section, we will provide a blackjack probability table that shows the probability of a dealer going bankrupt and how it can change depending on the house rules. Below is a table of statistics for the selected Blackjack.

Blackjack Payout

It’s a dream scenario to hit Blackjack with your first two cards. However, the size of the reward for this coveted opportunity varies from casino to casino.

While most of the best online casinos offer 3:2 payouts with a 0.5% casino edge, this is not always the case. Some sites pay out 6:5 or, in some cases, even cash for a blackjack payout.

Changes to the Rules and the Impact on Casino Benefits

Even minor changes in the rules affect the final results. This is especially true for the casino advantage and the dealer’s winning chances.

The Main Rules and Their Impact

Our team of experts reviewed the main rules that affect the house advantage in blackjack.

Hit or stand on Soft 17

The casino advantage is higher when the dealer stands has to hit a Soft 17 rather than stand on this value. The difference with the house edge increases by about 0.2% when the dealer hits a soft 17.

Re-split rules: If a player can make a hand with split aces, it reduces the casino advantage by 0.13%. If the aces can be split again, the house advantage is reduced by another 0.03%. The more restrictions the game places on your ability to split, the more likely it is that the casino will have a blackjack advantage.

Natural Blackjack Payouts

The standard payout for a Blackjack win is 3:2. Some blackjack tables pay 6:5 for a win in kind, or sometimes just pay even money. A 6:5 payout increases the casino’s edge by 1.4%, while a cash payout increases it by 2.3%.

Number of decks

The standard number of decks used by most online casinos today is eight. The fewer decks used, the more profitable it is for the player. If a casino offers blackjack with fewer decks and fewer disadvantageous rule changes, the casino advantage should be significantly lower than in other casinos.

No face card

Playing blackjack without the dealer’s face cards can change the blackjack odds with perfect strategy. This is because the player has no information about the probability and odds of winning blackjack of a complete win by the dealer. The result is a 0.11% increase in the Casino Advantage if all bets are lost as a result of the dealer’s blackjack, and no increase in the Casino Advantage if only the initial bet is lost as a result of the dealer’s blackjack.

What is the Charlie Card

Many variants of Blackjack allow players to automatically win if they draw a certain number of cards without being dealt. The addition of this rule is always beneficial to the player, but it is often accompanied by less favourable rules. Some variants also pay out “5 Card Charlies” with higher natural Blackjack odds of 3:2.

Blackjack Switch

Added features can change the nature of more unusual blackjack games. For example, in Blackjack Switch, players are dealt two cards and can swap the second card. This rule benefits the player, but it is countered by strange rules, such as the dealer hitting 22.


As you can see, there are many factors and blackjack strategies that influence the winning. Even a minimal change in the rules can increase the house advantage several times. That is why, before you sit down at the table (real or playing online blackjack), you should at least familiarise yourself with the basic concepts and rules. This will not only help you to win, but also save money from losing.
