Blackjack Odds and Payouts

Some Blackjack players play the game for the entertainment, others for the thrill. Some just want the big money that comes from playing smart and betting appropriately. One of the biggest influencers of that outcome is the odds. It’s important to know what the odds of winning are in any given game and in Blackjack, the odds are complex and often changing. It can be difficult for players to keep up with. However, we’ve got a great resource for you to utilize when calculating Blackjack odds while you play.

Calculating The Blackjack House Edge

The first thing to consider in any Blackjack game is the house edge. There are so many different rules and characteristics that can influence the house edge in a game of Blackjack. Fortunately, every online Blackjack game has to display the house edge in the full game rules. We couldn’t possibly trace all the games and list their rules with the associated house edge. However, what we can do is explain what factors influence the house edge and offer a few examples.

When it comes to the characteristics that influence the house edge, the biggest impact will come from how many decks are being used. Most games will tend to incorporate an even number of decks up to eight, though some do utilize five decks of playing cards.

The second influencer is the Dealer hit/stand rule on a soft 17. Whether they are forced to stand with a soft 17 or Hit with a soft 17 will directly influence the house odds on any given hand.

Doubling down on a player’s hand has two components that influence the house edge. The first is whether or not they are able to double after splitting a hand. The second will come into play depending on whether a player can double down on any hand, only 9-11, or only 10-11.

Splitting a hand has three component that influence the house edge to a large degree. Those include how many hands the player is allowed to resplit into, whether or not the player can re-split aces, and whether or not that player can hit on split aces.

Dealer Blackjack is another thing to consider. In this case, one must consider if the player loses their original bet to the dealer or any following bets, as well.

When it comes to the surrender rule, whether a player can utilize the rule at all and if, so, can they do so late will impact the house edge.

The last major influencer of house edge comes in the form of payout for a Blackjack. Blackjack tends to pay 3:2 or 6:5.

Taking all of these criteria into account, let’s try some examples:

Criteria Set #1 Rule Set #1
Number of Decks 1
Dealer Hit or Stand on Soft 17 Stands
Player Can Double After Split No
Player Can Double On Any
Player Can Resplit to 2 hands
Player Can Resplit Aces No
Player Can Hit on Split Aces No
Player Loses original bet to Dealer Blackjack No
Surrender Allowed None
Blackjack Payout 3 to 2
House Edge (basic strategy) 0.08093%

 

Criteria Set #2 Rule Set #2
Number of Decks 8
Dealer Hit or Stand on Soft 17 Hits
Player Can Double After Split Yes
Player Can Double On 10-11 Only
Player Can Resplit to 4 hands
Player Can Resplit Aces Yes
Player Can Hit on Split Aces Yes
Player Loses original bet to Dealer Blackjack Yes
Surrender Allowed Late
Blackjack Payout 6 to 5
House Edge (basic strategy) 1.86893%

 

As you can see, the two different sets of rules produce significantly different results. This is why doing a bit of homework to find the right combinations of rules that result in a lower house edge can mean a lot.

Blackjack Hand Odds

There are so many permutations of Blackjack hands and how they can be played against the dealer that even the most expert of players can be left frustrated in trying to think of the best next move.

Blackjack Insurance House Edge

As we’ve mentioned in our other Blackjack resources, insurance may or may not be offered as a way for players to minimize their losses at the tables. The efficacy for players’ benefit has been widely disputed. As a result, we’ve decided to include a little info on the house edge when it comes to insurance and the number of decks available in a given game of Blackjack. Here is the house edge compared to number of decks in play:

Number of Decks House Edge
1 5.9%
2 6.8%
4 7.25%
6 7.40%
8 7.47%

 

Blackjack Payouts

Blackjack games are not significantly different across variations when it comes to payouts. They most typically will pay out 3:2 or 6:5 for a Blackjack. However, there are Blackjack variations that increase the payouts to incredibly high amounts based on unique card configurations that reach 21. Take for instance a game which utilizes eight decks of cards. If the player can reach a hand valued at 21 with a hand consisting of suited 7s, they can win a payout of 100:1 or more. It’s a longshot to create such a hand, but that’s why the payouts for such configurations reach so high.

Now you know just about all there is to know when it comes to the most popular Roulette variations. Use this information to your advantage on the tables and enjoy lasting entertainment while you beat the house at their own game.
