Single Deck Blackjack Strategy

Blackjack remains one of the most popular table games today because it offers the best chance of winning. The Single-deck blackjack variant is fantastic, as it has the lowest house edge of all the blackjack games. This means that this variant of blackjack games gives players multiple advantages over blackjack games with higher decks.

In this article, we’ll discuss the single-deck blackjack game as well as how it differs from other variants of blackjack games in terms of gameplay and rules.

What is Single Deck Blackjack and Its Profitability?

In single-deck blackjack, you’re just dealing with one deck of cards, which makes things a bit easier and quicker compared to other versions of blackjack. With fewer cards in play, it’s also a bit easier for players because there’s less chance of getting busted.

Single deck blackjack can be profitable due to its lower house edge compared to multiple deck games. The single-deck blackjack has a house edge of around 0.15%. This means that players can easily win this variant of blackjack game. With fewer cards in play, skilled players can employ better strategies and card counting techniques, increasing their chances of winning. However, casinos often adjust rules to offset this advantage.

Single-deck vs multiple deck Blackjack games

Unlike multi-deck versions of blackjack, single-deck blackjack games offer payouts of 6:5, while multi-deck games pay 3:2. The single-deck blackjack game is widely played around the world and has a house edge of around 0.15%.

The single-deck blackjack game is much easier to play when compared to the multi-deck blackjack — because it’s possible to count cards in this variant of blackjack. That’s why casinos have begun offering blackjack games that have two or more decks — this makes it hard for players to count cards during gameplay.

Gameplay of the single deck blackjack

Unlike blackjack games with two or more decks, the single-deck blackjack game has interesting features and gameplay. You only need to get 21 points or as close to 21 as possible without going over it to win.

In the game, you only need to place your bet while allowing the dealer to deal the hands. At the table, you’ll get two face-up cards, and the dealer will get one face-up and one face-down.

Then you’ll need to evaluate your cards and the dealer’s one face-up card to decide whether to hit, stand, split, or double down. 

Rules of the single deck blackjack

Furthermore, when it comes to the rules of the blackjack games, they differ from single-deck to multi-deck and are as follows:

  • The Dealers must stand on soft 17.
  • Players can double down on any two cards.
  • Players can double down after splitting.
  • Players can or cannot resplit aces.
  • After splitting, an ace and ten value card (or Vice Versa) is not a blackjack.

In single-deck blackjack, whenever the dealer stands on soft 17, then it means that the dealer has no chance of improving his/her hand — this allows the player to make a move that may result in a win.

As for the double-down rules, this often adds an advantage to your bet. For instance, when a player double-down after splitting a pair, it gives the house a disadvantage while giving the player up to 13% in advantage.

Moreover, make sure that you have a surrender rule included in your game as this can be useful during gameplay. However, it’s best to use the surrender strategically and not aggressively.

Basic strategy for the single-deck blackjack

Similar to any other variant of blackjack, the single-deck blackjack is a lovely game that can be utilized if studied carefully. In a game of blackjack, every single card that is played has an impact in the game — more than it does in multi-deck games.

So, players with a unique skill such as card counting can use this loophole to their advantage, by always paying attention to the cards being played to decode what possible card the dealer may be holding.

But one more thing, keep in mind that blackjack skills and strategies need to be learned and understood before they can be used effectively during gameplay. Also, the single-deck blackjack strategy often depends on the house rules and this may differ according to the different varieties of blackjack game.

There are a lot of strategies you can utilize when playing single-deck blackjack such as card counting and more. However, you shouldn’t forget the basic strategies when you are at the table or playing single deck blackjack online.

So, it’s best to implement your basic knowledge of distributing cards when necessary without taking insurance or even money because the house edge on insurance is around 5.9% in single-deck blackjack — and that’s high.

Lastly, always bet responsibly according to your bankroll — thereby wagering what you can afford to lose. Remember, gambling is a game of luck and it’s all about having fun!


The single-deck blackjack game has only one deck which is important because it allows the players with card counting skills and other strategies to decode the remaining cards in the deck during gameplay — thereby being able to know what cards a dealer could have or is likely to have.
