Single-Deck Blackjack FAQs
We all know that Blackjack is one of the most popular table games out there.
But have you tried Single-Deck Blackjack?
If you want to play the version of blackjack with the best chance of winning, you’ll need a simple single-deck blackjack strategy and a few tips.
What is Single Deck Blackjack?
Let’s start with a few fundamentals:
- Single-deck blackjack games have the lowest house edge of all games.
- The low house edge gives players multiple advantages over the classic multi-deck game.
But before you get excited and jump into a game, you’ll need to learn some key strategic points, as well as the differences between playing single-deck blackjack and standard multi-deck, and more about the rules.
Single-Deck vs Multiple Deck Blackjack
The key difference between single-deck and multi-deck versions of blackjack? Besides the number of decks, the other key difference is the payout — you’ll find that many casinos offer payouts of 6:5 in single-deck games, while multi-deck games generally pay 3:2.
Back in the good old days of classic blackjack, single-deck blackjack was the standard. It was a popular game, played widely around the world, with blissful players taking advantage of the 0.15% house edge.
The use of one card deck, made it much easier to count cards, and thus, the single-deck version became popular with card counters, who swooped in with their own single-deck blackjack strategy to take a piece of the pie.
Casinos quickly caught onto this, and began introducing blackjack games with two or more decks, in order to raise their own edge and make it harder to count cards.
What is House Edge?
The house edge tells a player the advantage that a casino has over them when playing a specific game, usually expressed as a percentage. House edge determines the chance of winning and a payout; games with a lower house edge have more chances of being won.
Rules & Gameplay for Single-Deck Blackjack
The basic concept and objective remain the same in single-deck blackjack: you want to get to 21 points or as close to 21 as possible without busting.
You’ll place your bet, then the dealer will deal the hands. You’ll get two face-up cards, and the dealer will get one face-up and one face-down.
You’ll study your cards and the dealer’s upcard, then decide to hit, stand, split, or double down.
Remember, both land-based and online casinos usually have specific rules for single-deck blackjack, which differ from multi-deck. These include:
- Whether or not the dealer hits or stands on soft 17
- Whether or not players may double down after a split
- If and when players can surrender
It’s common to have the dealer hit on a soft 17, to prohibit players from doubling down after a split, and to prohibit surrender because these rules increase the house edge.
However, these and other rules will vary depending on the online casino site of your choice

Single Deck Blackjack Strategy: Our Tips
It’s imperative you learn how to make a decision as a player and follow the basics of single-deck blackjack strategy as you play.
Remember that every single card that is played in the single-deck game has an appreciable impact on the distribution of the remaining cards in the deck, more so than in multi-deck games.
Use this to your advantage, and always pay attention to the cards being played.
It’s also a good idea to consult some blackjack basic strategy charts to figure out the optimal play for your hand.
Our Blackjack Cheat Sheet displays possible hands in conjunction with possible dealer upcards, telling whether you should split, double down, stand, or hit for that specific combination of cards.
The Optimal Plays for Single-Deck Blackjack
Assuming that the dealer hits on soft 17, doubling down after a split is not allowed, and surrender is not allowed, you can follow these guidelines:
Hard Hands Table
| Cards | The Play |
|---|---|
| 5-7 | Always hit |
| 8 | Double if dealer shows 5 or 6, otherwise hit |
| 9 | Double if dealer shows 2-6, otherwise hit |
| 10 | Double if dealer shows 2-9, otherwise hit |
| 11 | Always double |
| 12 | Stand if dealer shows 4-6, otherwise hit |
| 13 | Stand if dealer shows 2-6, otherwise hit |
| 14 | Stand if dealer shows 2-6, otherwise hit |
| 15 | Stand if dealer shows 2-6, hit on 7-ace |
| 16 | Stand if dealer shows 2-6, hit on 7-ace |
| 17-21 | Always stand |
Soft Hands Table
| Cards | The Play |
|---|---|
| A-2 | Double if dealer shows 4-6, otherwise hit |
| A-3 | Double if dealer shows 4-6, otherwise hit |
| A-4 | Double if dealer shows 4-6, otherwise hit |
| A-5 | Double if dealer shows 4-6, otherwise hit |
| A-6 | Double if dealer shows 2-6, otherwise hit |
| A-7 | Double if dealer shows 3-6, stand on 2, 7, & 8, hit on 9, 10 & ace |
| A-8 | Double if dealer shows 6, otherwise stand |
| A-9 | Always stand |
| A-10 | Always stand |
Pairs Table
| Cards | The Play |
|---|---|
| 2-2 | Split if dealer shows 3-7, otherwise hit |
| 3-3 | Split if dealer shows 4-7, otherwise hit |
| 4-4 | Split if dealer shows 4-6, otherwise hit |
| 5-5 | Double if dealer shows 2-9, hit on 10 & ace |
| 6-6 | Split if dealer shows 2-7, otherwise hit |
| 7-7 | Split if dealer shows 2-7, stand on 10, hit on 8, 9 & ace |
| 8-8 | Always split |
| 9-9 | Split if dealer shows 2-6 and 8-9, otherwise stand |
| 10-10 | Always stand |
| Ace-Ace | Always split |
Keep in mind that this is not an optimal strategy for every game, because you won’t just make different plays according to the dealer’s upcard; also your single deck blackjack basic strategy is dependent on the house rules.
Single-Deck Blackjack House Rule Variations
If the dealer stands on soft 17, you know that he has no chance of improving this hand. Keep this in mind as you make your decisions, because it actually increases your odds of beating him with certain plays.
Double-down rules will affect your bets, so pay close attention to them.
If you can double down after a split, you’ll want to be a bit more aggressive with your splits than the guide displays—for example, you could split a pair of 3s if the dealer shows 2 or 3, not just 4 through 6.
Likewise, if you can surrender, you’ll want to do so strategically. For example, if you have a pair of sevens and the dealer shows 10, you know your odds aren’t good, so surrendering would be the best option.
Single-Deck Blackjack Strategy: Tips for the Table
When you’re at the table, keep these tips for blackjack basic strategy in mind:
- Use your knowledge of the cards that have already been played to infer which cards may come up. Remember, this knowledge comes easier when you play with a single deck.
- Never take insurance or even money, because the house edge on insurance is 5.9% in single-deck blackjack
- Use a responsible betting strategy, making wagers which fit with your bankroll and allow you to bet for longer. Remember, it’s all about having fun.
Now that you know about single-deck blackjack strategy, it’s time to try a hand at the tables with this action-packed game.
Where to Play Single-Deck Blackjack Online

We’d also suggest the blackjack library at PokerStars Casino who operate in all legalized gambling states bar WV. Not only does their standard blackjack game provide an ideal opportunity to practice your strategy, but the PokerStars site also offers a number of ‘How to Play’ guides.
Outside of the states offering legal online blackjack, you can often find a free blackjack game at some of the bigger social casinos, although we can’t guarantee which variant of blackjack game you’ll be able to access on these sites. Nonetheless, brands like Chumba Casino, Pulsz Casino, and Slotomania should be top of mind if you want free single-deck blackjack.
