This manual acquaints you with the odds of twenty-one, likelihood, the house edge, and how to optimize your wagers. Therefore, let us commence.
Twenty-One Rules
The rules of twenty-one are quite simple. Familiarizing yourself with them prior to proceeding will facilitate a better understanding of how twenty-one odds and likelihood operate. Hence, we have compiled some essential details to serve as your groundwork.
- During a round of twenty-one, each card possesses a distinct value:
- Cards 2-10 maintain their face value
- Picture cards (Jack, Queen, and King) each hold a value of 10.
- Aces are more adaptable and can be valued as 1 or 11 based on what suits your hand better.
- The objective of twenty-one is to exceed the dealer’s hand without surpassing 21.
- Going over 21 results in a “bust,” causing you to forfeit your bet and hand participation.
- A hand totaling precisely 21 constitutes twenty-one and secures an automatic victory.
What Are Twenty-One Odds & Stats?
Prior to delving into twenty-one odds, let us initially review the odds. Odds shed light on two aspects for a twenty-one participant: their chances of succeeding in a specific wager and the amount they could potentially earn upon winning.
Within twenty-one, there exist two sets of odds: the player’s odds (that’s you) and the dealer’s odds (if you are engaged in online play, this corresponds to the computer.) Let us delve deeper into each set.
Participant’s Twenty-One Odds Chart
You can heighten your twenty-one probability using various techniques such as strategic card counting (albeit unachievable in online play).
Nevertheless, a casino can lower your odds through methods such as reducing payouts, incorporating more decks into the shoe, or imposing regulations like disallowing doubling after splitting.
<p/Hence, a solid comprehension of your twenty-one probability offers the optimal approach to identify any advantages you might possess.The table below showcases a chart of twenty-one odds, outlining the likelihood of deciding to hit following the dealer dealing your initial two cards.
The Player – Bust Probability
Hand Value | Probability |
11 or below | 0% |
12 | 31% |
13 | 39% |
14 | 56% |
15 | 58% |
16 | 62% |
17 | 69% |
18 | 77% |
19 | 89% |
20 | 92% |
21 | 100% |
Dealer’s Twenty-One Odds Chart – Statistics
All twenty-one casinos enforce a house edge, granting the dealer an inherent advantage and superior odds of triumphing in twenty-one over you. The dealer’s ability to act after you, basing decisions on your outcomes, further solidifies their edge.
<p/Nonetheless, remember that the house policies governing the game will impact the dealer’s twenty-one odds. For example, a dealer compelled to hit on soft 17 possesses a higher success likelihood compared to one required to stand on soft 17.<p/Referenced below are the probabilities of a dealer going bust and how modifications to house rules can influence this scenario.Twenty-One Dealer’s Probability of Busting
Dealer’s Card | Probability – Stand on 17 | Probability – Hit on 17 |
Ace | 17% | 20% |
2 | 35% | 36% |
3 | 37% | 38% |
4 | 40% | 40% |

What Are the Odds of Succeeding in Twenty-One?
<p/Your chances of winning in twenty-one can skyrocket to 42.22%. Nevertheless, this does not signify that the remaining 57.78% automatically favors the house.<p/Instead, a third scenario exists where the round culminates in a push (a draw between the player and dealer). Typically, a twenty-one match possesses an 8.48% likelihood of concluding in a push.<p/In essence, the probability of losing in twenty-one stands at about 49.10%.
Informative Pointer
<p/In twenty-one, a “push” signifies a situation where both player and dealer end up with identical hand values, resulting in the player receiving their initial wager back.
<p/Your chances of triumphing in twenty-one can fluctuate and predominantly hinge on the game version you select, the player and dealer regulations enforced, and your gameplay approach.<p/For instance, opting for arbitrary stakes rather than adhering to a consistent strategy significantly diminishes your winning prospects. To enhance your chances of success, it is advisable to thoroughly grasp the techniques of playing twenty-one and implement one or more strategies to sustain a smooth run.
How do the Chances Vary Across Various Blackjack Games?
Comparing the odds of winning at blackjack predominantly hinges on the type of game you opt to engage in, making it crucial to examine the different variations and their distinct probabilities. Have a glance below.
American / Classic Blackjack
The prevalent type of blackjack in most casinos is Classic or American Blackjack. This version involves playing with a deck of 52 cards. In this game, the probability of winning blackjack stands at 42.22%, while the likelihood of hitting 21 is 4.75%.
Considering the house advantage in classic blackjack generally stands at 0.61%, it indicates that if you bet $100 on a game, the casino will gain $0.61. The odds being set at 3/2 mean that if you win your bet, you will receive 1.5 times your original wager.
Therefore, by betting $100 and emerging victorious, your profit would amount to $150, resulting in a total payout of $250 (original bet + profit).
The chances of acquiring a specific hand in classic blackjack are detailed as follows:
Hand Value | Likelihood |
21 | 4.8% |
17-20 | 30% |
1-16 | 38.7% |
No Bust | 26.5% |
European Blackjack
European blackjack slightly deviates from the classic variant. The gameplay involves utilizing two 52-card decks. Furthermore, in this iteration, the dealer refrains from drawing additional cards after reaching a soft 17; however, given that they don’t peek at their cards, you might be wagering for naught in case they secure the winning hand.
Due to these balancing factors, the odds of winning at European blackjack closely resemble those of classic blackjack, hovering around 42%.
Though the odds in the European version are also configured at 3/2, the game proves to be more lucrative owing to a diminished house advantage of 0.39%, thus leading to higher profits upon winning.
Useful Tip
In the realm of blackjack, “hitting” denotes opting to draw another card to attempt to reach 21. However, if an additional card risks exceeding 21, you may opt to refrain from drawing further cards or “stand.”
Blackjack Switch
Another rendition of blackjack is blackjack switch, where you play with two hands while adhering to the regulations of American or classic blackjack. Nonetheless, you have the liberty to ‘switch’ between hands during gameplay.
For instance, if your hands comprise cards like 3 and 11 in one hand and 9 and 10 in the other, you can interchange the 3 and 10 to culminate in 21 (blackjack) in one hand and 12 in the other.
Blackjack switch boasts the same likelihood as other versions, set at 42%, owing to distinct rules such as all wagers resulting in a draw if the dealer hits 22.
Furthermore, the house edge for switch blackjack is inferior to that of classic blackjack, standing at 0.58% – among the most lenient. Nonetheless, the odds are established at 1/1, translating to lower payouts than those in American blackjack. In this scenario, for every $100 staked, you retrieve $100 in profits.
Face Up 21
In this favored rendition of the game, all cards are displayed face up, facilitating visibility of the dealer’s cards. The chances of winning in Face Up approximate 42%. Nevertheless, in Face Up, a tie doesn’t culminate in a draw but rather a loss.
Here, the house advantage in blackjack surpasses that of all other versions, reaching 0.85%, with winning odds set at 1/1. Consequently, players seeking profitability seldom opt for this variation.
Nonetheless, it serves as an ideal choice for novices endeavoring to refine their strategies or individuals merely seeking recreational play.
Free Bet Blackjack
In this distinctive variation, you can incorporate specific augmentations to your gameplay at no additional cost.
For instance, you are permitted to split pairs or utilize one card for each hand when they match. Alternatively, you could double your bet mid-hand upon possessing a hard 9, hard 10, or hard 11.
Free bet blackjack demonstrates the highest house edge thus far, tallying at 1%; however, this is somewhat offset by the odds of 3/2.
Online Blackjack – You vs The Computer
Participating in blackjack against a computerized opponent at an online casino, commonly referred to as video blackjack, entails the utilization of random number generation (RNG) software by the casino to ensure equitable gameplay. Typically, this variant entails utilizing only a solitary deck.
The house edge here can fluctuate between 0.5% and 2% contingent upon the casino you select. Again, the odds present a range between 1/1 and 3/2.
Online Blackjack – Live Dealer Games
For an authentic blackjack experience in the online realm, opt for live dealer gaming. This avenue provides the opportunity to partake in a live casino game from the comforts of your abode.
In essence, live dealer blackjack adheres to the regulations and format of classic blackjack. The house advantage in blackjack herein oscillates between 0.49% and 0.72%, contingent upon your chosen casino. Furthermore, the odds are favorable, typically configured at 3/2.
Comparing the Odds: Blackjack Variations
Though an option like a blackjack odds calculator remains available to help you evaluate the odds for each of the aforementioned variations, we opted for a simplified approach by compiling a comparative table:
Blackjack Variation | Odds | House Edge |
American/Classic Blackjack | 3:2 | 0.61% |
European Blackjack | 3:2 | 0.39% |
Switch Blackjack | 1:1 | 0.58% |
Face Up 21 | 1:1 | 0.85% |
Free Bet | 3:2 | 1% |
Online – Video Blackjack | 1:1 or 3:2 | 0.5% and 2% |
Online – Live Dealer Blackjack | 3:2 | 0.49% and 0.72% |
Blackjack Hands and Their Odds
In addition to conventional blackjack, an array of other options or side bets can be explored. These alternatives adjust the blackjack odds and the ensuing payouts, underscoring the importance of understanding their function, mechanism, and impact on your likelihood of success.
Insurance
Among the prevalent side bets within blackjack is insurance. This wager, present across all variants of the game, affords you the opportunity to safeguard half of your stake. Simply put, if the dealer reveals an Ace and achieves a blackjack, you secure a payout and manage to break even.
Surrender
If you harbor suspicions regarding the adequacy of the true odds of triumphing in blackjack, the casino might permit you to surrender. Two approaches exist:
- Early surrender enables you to forfeit half of your bet prior to the dealer inspecting for a blackjack. However, casinos seldom extend this privilege.
- Late surrender allows you to abandon half of your wager subsequent to the dealer verifying their cards. Typically, this option is standard at casinos.
Deck Quantity Utilized
The number of decks featured in a blackjack game at a casino spans from one to eight. While the blackjack odds persist unchanged, the likelihood undergoes slight permutations.
Though the probability of winning at blackjack remains consistent, the likelihood of achieving blackjack (21) fluctuates. Moreover, the house edge is also influenced by the number of decks employed, with the variance extending by 0.56% from a one-deck game to an eight-deck game.
21+3
Thisside wager gives you the opportunity to bet on the dealer’s face-up card and your initial two cards. In this scenario, you have five choices to place your wager on and we’ll examine each of them along with their corresponding odds below:
Wager Kind | Bet Explanation | Chances |
Flush | Three cards of the same kind or suit (for example, all hearts or all spades). | 5:1 |
Straight | Three cards in consecutive order (for instance, 3,4,5). | 10:1 |
Triplet | Three cards of identical face or total value (such as a queen of diamonds, a queen of clubs, and a queen of spades). | 30:1 |
Straight Flush | Three cards of the same suit in consecutive sequence (like three of diamonds, four of diamonds, and five of diamonds). | 40:1 |
Identical Triplet | In games with multiple decks, all three cards must have the same face value and suit (such as three jacks of spades). | 100:1 |
Despite the exceptional odds provided for 21+3, the likelihood of hitting one of these bets is minimal. Additionally, bear in mind that the house advantage in blackjack is high, varying between 6.29% and 8.78%, based on the number of decks in play. However, it works inversely here, as the more decks used, the lower the house edge.
Perfect Matching
This bet functions akin to 21+3, but concentrates solely on your cards and their matches. Here, you have three types of perfect matches to bet on:
Wager Kind | Bet Explanation | Chances | Probability |
Identical Pair | Two cards that are the same (for instance, 2 x two of spades). | 25:1 | 1.69% |
Colored Pair | Two cards of the same value and color (for example, king of hearts and king of diamonds – both red). | 12:1 | 1.93% |
Mixed Pair | Two cards of the same value (like a two of diamonds and a two of hearts). | 5:1 | 3.86% |
Even though the odds are appealing here, the chances are extremely slim. Additionally, the house edge falls between 2% – 11%, which is comparatively high when compared to other blackjack bets.
Doubling Down
This choice enables you to double your bet during a hand. While the odds remain steady at 3:2, you have the potential to double your winnings since you are essentially betting on the result twice.
Division
Certain casinos permit division, where you can “split” your initial two cards into separate hands. Nevertheless, the casino mandates a second bet on your newly formed hand.
Splitting can prove advantageous if the dealer has a weak hand. In this case, the blackjack odds stand at 3:2 upon division.
6 to 5 Chances
Although 3:2 odds are commonplace in casinos, 6:5 odds are becoming more prevalent as the standard in Vegas blackjack odds. Nonetheless, it is crucial to discern the distinction here:
- 3:2 odds yield 1.5 times your initial wager
- 6:5 odds yield 1.2 times your original bet
To simplify, 6:5 odds offer lower returns and could lead to losses. Hence, when presented with both 3:2 and 6:5 odds, always opt for the 3:2 alternative.
Comprehending A Blackjack Payout
Your blackjack payout varies based on the casino you engage with. Typically, a casino will present blackjack payout chances of 3:2 with a house edge hovering around 0.5%. Nevertheless, other establishments might propose payout odds of 6:5 or 1:1 (even money). The payout odds directly impact the house edge.
Blackjack Payout Table
Given that blackjack payouts are relatively straightforward and typically set at 3:2, 6:5, or 1:1, they are straightforward to calculate. However, their implication on the blackjack house advantage is slightly more complex. Therefore, we have crafted the following blackjack payout table for your convenience:
Blackjack Payout | Blackjack House Edge |
3:2 | 0.5% |
6:5 | 1.9% |
1:1 (even money) | 2.8% |
Blackjack Likelihood
Although the terms odds and probability are often used interchangeably, they carry distinct connotations and have several notable variances. We outline these variations below:
Likelihood
We utilize probability to gauge the likelihood of our blackjack bet succeeding. Calculating probability is straightforward, involving dividing the anticipated winning likelihood by all feasible outcomes.
Assume we have five cards and must select one, our probability calculation is as follows:
1 (anticipated win likelihood) / 5 (all possibilities) = 0.2 or 20%.
Odds
Blackjack odds provide a measure of probability and the potential payout we can receive on a specific bet. For example, having five cards and selecting one yields odds of 4:1. In this scenario, we have four chances of losing and one chance of winning.
However, typically, the second figure doesn’t actually signify the likelihood of winning blackjack but rather the payout offered for that particular bet.
The Likelihood of Winning Blackjack
Playing blackjack with a single deck comprising 52 cards places the odds of drawing blackjack (21) at 32/663 or 4.83%. In simpler terms, your chances amount to 1 in every 20 rounds.
However, if you are exploring the finest online gambling platforms employing RNG software, the blackjack likelihood remains steady at 4.83% when engaging in single-deck blackjack.
Transitioning to multi-deck blackjack slightly lowers the probability, albeit minimally. For instance, a standard six-deck setup typically carries a 4.75% probability.
To save you the trouble of computing the probabilities for various deck numbers using a blackjack odds calculator, we have designed the subsequent chart:
Number of Decks | Probability |
1 | 4.827% |
2 | 4.78% |
3 | 4.764% |
4 | 4.757% |
5 | 4.752% |
100 | 4.735% |
Blackjack House Edge
Blackjack distinguishes itself as one of the casino games with the most meager house edge or advantage. By deploying the optimal blackjack strategies, you can further minimize the blackjack house odds. Below, we delve into the blackjack house advantage and its mechanisms.
Decoding the House Edge in Blackjack
The house edge signifies the casino’s competitive edge over its patrons. Given that the casino provides the entertainment, it charges a commission, utilizing the house edge to calculate the portion of your initial wager it can categorize as profit.
Physical and remote online casinos employ the game rules to compute the blackjack house edge they impose. Introducing a house edge is one strategy utilized by casinos to mitigate losses when a significant win occurs. Furthermore, the blackjack house advantage diminishes the likelihood of a substantial loss and enhances the establishment’s profit retention.
Secure a victory in your game, assisting the casino in upholding its profits and edge.
Blackjack is favored by players for possessing one of the most advantageous house edges. Nevertheless, it’s essential to bear in mind that while a classic blackjack game may entail minimal blackjack house odds, alterations to the game could introduce a slightly elevated house edge.
Strategies for Reducing the Blackjack House Edge
To diminish the blackjack house advantage and heighten your likelihood of success, it’s crucial to grasp which decisions to execute and precisely when to make them, such as determining the right moments to stand or hit.
Maintaining a composed and controlled demeanor during the game is also essential. Despite how simple it is to become engulfed in the thrill, this is when inadvertent errors may arise. Thus, adhering to your selected strategy and maintaining unwavering focus on the game is key.
Useful Tip
Physical casinos generally enforce a marginally increased house edge compared to their online counterparts due to higher operational costs. Therefore, if you aim for the most favorable blackjack house odds, consider utilizing an online casino.
Blackjack Odds Compared to Other Table Games
Blackjack boasts some of the finest odds available. Nonetheless, you might be curious to discover how these odds stack up against those offered by other renowned casino games. Below is a table displaying the top casino games with their respective odds.
Casino Game | House Edge |
Blackjack | 0.43% – 2% |
Bingo | 2.5% – 11% |
Baccarat | 1.06% – 1.24% |
Roulette (Single Zero) | 2.7% |
Roulette (Double Zero) | 5.3% |
Craps | 1.36% – 1.41% |
Ultimate Texas Hold’em | 2.20% |
Pai Gow Poker | 2.84% |
Video Poker | 0.05% – 2% |
Video Keno | 8% – 15% |
Slots | 5% – 15% |
Blackjack Return to Player (RTP)
The RTP, or return to player, represents the inverse of the house edge. This figure elucidates the expected returns you could receive by engaging in numerous rounds of blackjack. Essentially, while the house edge signifies the casino’s advantage, the RTP showcases that of the player.
For instance, if a game bears an RTP of 97%, it signifies that, on average, for every $100 wagered, you might expect a return of $97 over an extended period. Nevertheless, this outcome is not guaranteed.
Blackjack features a relatively high RTP of 99.5%; however, this may fluctuate depending on the online variant being played, with popular iterations typically offering a more elevated RTP. It’s advisable to verify the RTP of an online game by referring to the game’s information section. Opting for games with the highest RTPs is typically recommended.
Frequently Asked Questions About Blackjack Odds
What are the optimum odds at the blackjack table?
Presently, you can encounter blackjack odds of 6:5 and 3:2. Although 6:5 odds may appear superior, they do not offer the best value. Odds of 3:2 provide a payout of 1.5 times your initial stake, while 6:5 odds result in a payout of 1.2 times your root stake. Consequently, the most advantageous odds at a blackjack table are 3:2.
