Blackjack Odds Explained

When playing any casino game, odds determine the statistical probability of specific outcomes and therefore influence decisions that can make or break your bankroll. Mastering blackjack odds helps shift the advantage back into your favour. 

But first, a quick recap of the fundamentals.

Blackjack Rules

The aim of blackjack is simple – beat the dealer by getting card totals as close to 21 as possible without going over. Numbered cards count as their face value while face cards count as 10. An ace can count as 1 or 11. The best hand is blackjack (an ace with a 10-point card) 뉴헤븐카지노쿠폰.

What Are Blackjack Odds?

Blackjack odds denote the statistical probability of a specific result, calculated by dividing the number of desired outcomes by the total number of possible outcomes. Understanding the odds for every potential scenario allows players to make optimal choices to boost their chances of winning.

Follow it and the house edge drops from 5% down to just 0.5%!

How do the Odds Between Different Blackjack Games Compare?

While the fundamentals remain the same, small tweaks in rules can affect odds and favorability across popular blackjack variants both online and in land-based casinos. Understanding these subtleties allows you to seek out or avoid specific games.

American / Classic Blackjack

The original incarnation of the game with the most balanced set of rules. The odds of winning generally hover close to 50/50 depending on the correct strategy.

European Blackjack

Played with only two decks offering slightly better odds for the player. The dealer does not take a hole card which reduces the house edge too. Popular online and with lower betting limits.

Handy Hint

Unless posted otherwise, always assume the dealer stands on soft 17 – where an ace can count as 11 without the total exceeding 21. This happens around 70% of the time, hurting the player’s odds significantly.

Blackjack Switch

Invented by Geoff Hall in 2009, players make two equal bets and receive two hands that they can switch top cards between to form better combinations. Improves player odds.

Face Up 21

In a proprietary game by Gabriel Technologies, the dealer receives two cards face up. All player blackjacks pay even money instead of 3:2 however, balancing overall odds.

Free Bet Blackjack

Like classic blackjack but with a twist – players automatically win if holding 20+ and dealer busts. You also get a free double down on hard totals of 9, 10 or 11 regardless of hand total. Boosts RTP to over 99%.

Online Blackjack – You vs The Computer

Fairly standard blackjack with odds hovering close to 99% RTP depending on specific rules. No need to wait for other players – it’s you against the machine.

Online Blackjack – Live Dealer Games

Streamed real-time action with a human dealer and table limits to suit all bankrolls. As authentic as visiting a land-based casino. Combined player odds are generally over 99% RTP.

Comparing the Odds: Blackjack Variations

Game Odds/RTP (Return to Player)

  • American Blackjack 99.54%
  • European Blackjack 99.65%
  • Free Bet Blackjack 99.65%
  • Blackjack Switch 99.87%
  • Single Deck Blackjack 99.92%
  • Double Deck Blackjack 99.64%
  • Face Up 21 99.46%
  • Live Dealer Blackjack Up to 99.95%

Blackjack Hands and Their Odds

Let’s examine how certain hands, options and side bets influence mathematical probability at the blackjack table. Understanding these intricacies allows you to manipulate the odds in your favour.


When the dealer shows an ace, the odds dictate they have a 1 in 3 chance of blackjack. Most players decline insurance when offered as the odds just don’t outweigh potential returns even accounting for strategy.


Surrender allows players to forfeit half their bet if unhappy with the initial deal. It cuts losses short against strong dealer hands. Factoring this into gameplay strategy adjusts overall odds favourably.

The Number of Decks Used

Single-deck blackjack offers the best odds but is extremely rare outside online games. Typically either 6 or 8 decks are used. More cards make card counting futile and swing odds back into the casino’s favour.

21+3 Rule

A popular side bet based on your first two cards and dealer upcard forming specific poker hands. Tough odds range from 100:1 for a straight flush down to just 3:1 on certain triples.

Perfect Pairs

Wager on your initial two cards forming a mixed, coloured or identical pair. Pays from 6:1 up to 25:1 depending on win odds rarity. Overall RTP is still well below 100% so more of a fun occasional flutter.


Doubling your wager when the odds are strongly in your favour is a powerful tool for boosting potential winnings. Learn the correct strategy to maximize without busting out!


Separating initial card pairs into two hands allows two chances to beat the dealer’s hand. Improves your odds significantly when played strategically. But avoid splitting 5’s or 10’s.

6 to 5 Odds

If a blackjack payout offers just 6:5 instead of the standard 3:2, walk away! This single change boosts the house edge up from around 0.5% to a massive 1.39% – almost triple.

Understanding A Blackjack Payout

Payouts vary based on the size of the player’s wager and the cards dealt. Let’s break down how standard returns are calculated and the impact of rule variations.

Blackjack Payout Chart

Hand Payout

Blackjack: 3 to 2 or 6 to 5

Winning hand: 1 to 1

Push (Tied player/dealer hands): Original bet returned

Insurance: 2 to 1

Blackjack Probability

Mastering odds and probabilities is key to optimal blackjack strategy and maximizing your edge. Let’s clarify the difference and break things down further.


The likelihood of any given outcome is expressed as a percentage. E.g. The probability of being dealt a natural blackjack is approx 4.8%.


The ratio between desired outcomes versus total possible outcomes. E.g. Odds of being dealt a 20 are 23.3% based on total potential card combinations.

The Probability of Winning Blackjack

Though affected by skill level, knowledge of probabilities allows card counters to flip the odds against the house:

Average player probability: 42-48%

Basic strategy player probability: 48-50%

Card counter probability: 50-55%

Blackjack House Advantage

What is the House Edge in Blackjack?

Also called the RTP (Return To Player), this denotes the average casino profit as a percentage of total wagers. Blackjack generally ranges from 0.28% up to 1.39% depending on specific rules and payouts.

How to Minimize the Blackjack House Edge

Follow basic strategy guidance for optimal gameplay decisions based on your hand versus the dealer’s upcard. This alone reduces the house advantage down to around just 0.5%.

Handy Hint

Seek out blackjack games offering surrender options and always avoid unfavourable rules like 6:5 payouts on blackjack which substantially increase the house edge.

Blackjack Odds vs Other Table Games

Game Odds Favorability

Baccarat 1.06% – 1.24% Most favorable

Blackjack 0.28% – 1.63% Second most favorable

Craps 1.41% Third most favorable

Roulette 2.7% Higher house edge

Poker (3% rake) Higher house edge when rake considered

Blackjack Return to Player (RTP)

The RTP denotes overall estimated returns to players over extended gameplay. The higher the RTP, the lower the house advantage. Live blackjack games often offer the highest RTP of 99.5% or more.
