Everything You Need To Know About Single Deck Blackjack
Single deck blackjack is the simplest form of the game, played with a single deck of cards, and offers a house edge which is smaller than games with multi-deck games.
What is Single Deck Blackjack: What You Need to Know
Single Hand Blackjack is a variant of the classic card game blackjack that is played with a single deck of 52 cards. The objective of the game is to beat the dealer’s hand by having a hand value closer to 21 without exceeding it.
Here are the key features of Single Deck Blackjack:
- Gameplay: Each player and the dealer get two cards, with one dealer card face up and one face down. Players can see the dealer’s visible card to make their decisions.
- Options: Players can hit for another card, or may stand, split pairs, or double down based on house rules.
- House Rules: Typically, the dealer hits on a soft 17. Players can split their hands up to three times, but splitting Aces allows only one additional card, and a split Ace with a ten does not count as blackjack.
- Winning Conditions: Players win if their hand is 21 or less and higher than the dealer’s total, or if the dealer busts.
- Advantages: A single deck provides a lower house edge than multiple decks, making card counting easier, although frequent shuffling can hinder this strategy.
Overall, Single Deck Blackjack is preferred for its simplicity and better odds.
Single-Deck Blackjack Strategy Chart
The first thing we need to do when examining single deck blackjack is to present a chart of basic blackjack strategy.
Many sites have broken down this basic strategy chart into three separate sections: hard totals, soft totals and pairs. Below, we have grouped them altogether for one simple single-deck blackjack cheat sheet.
Single Deck Blackjack vs Multideck
Single deck games offers the player better chances to win than multi-deck. The house take is low even when the deck is shuffled after each hand.
Typically the return to player (RTP) on the best single deck game is 99.8%, whereas with a 6-deck game or 8-deck game decks the RTP is around 99.5%.
This difference might not seem that significant, but if you start with a deposit of $100, you might place 1000 bets of $10 each. At the end of that time you would have, on average, $80 remaining at 99.8% but only $50 remaining if the RTP is 99.5%
Of course, with just a smidgeon of good luck you can come out ahead and most of the welcome offers cover the potential loss.
Perfect play, particularly with more than one seat at single-deck, is quite complicated, but, if you follow the chart above, you will do well.

Is Single Deck Blackjack Good Odds?
Yes, single-deck blackjack generally offers better odds for players compared to multi-deck blackjack games. This is primarily due to the following factors:
- Higher Probability of Blackjack: The probability of getting a blackjack (an ace followed by a ten-value card) in a single-deck game is approximately 4.82%, or about 1 in every 20.72 hands. In contrast, the probabilities are lower in multi-deck games (e.g., 4.74% for six decks). This means players have a better chance of hitting a blackjack in a single-deck game.
- Lower House Edge: The house edge in single-deck blackjack is around 1.45%, which is lower than the typical house edge of 0.46% to 0.65% found in multi-deck games. A lower house edge translates to better odds for the player.
- Impact of Card Removal: In single-deck games, removing a card significantly affects the probabilities of the remaining cards. This has a more pronounced impact compared to multi-deck games, where the effect of removing a card is diluted across many decks.
- Better Payouts: While the payout for blackjack may be different (6:5 in single-deck compared to 3:2 in multi-deck at some casinos), the overall probability of achieving a blackjack and the lower house edge in single-deck games can make them more favorable in the long run.
- Basic Strategy Differences: The basic strategy for single-deck blackjack can be more advantageous for players, as it is tailored to the specific dynamics and probabilities associated with a single deck.
In summary, single-deck blackjack can provide better odds for players, making it a more appealing option compared to games with multiple decks, especially for those who employ basic strategy and are aware of the house edge.

Who has the Advantage in Single Deck Blackjack?
In single-deck blackjack, players generally have a greater advantage compared to other variations of blackjack due to several key factors:
Lower House Edge
Classic single-deck blackjack typically has a lower house edge than multi-deck games. This means that players have a better chance of winning over the long run when playing single-deck compared to games that use multiple decks.
Easier to Learn
With only one deck of cards, the game is simpler and easier for players to learn and understand. New players can grasp the basic strategy more quickly, which can enhance their overall performance.
Predictability
One key difference for single deck blackjack versions is that fewer cards in play make the game more predictable. Players can more accurately calculate the odds of certain cards appearing, which can lead to better decision-making during play.
Card Counting
Single-deck blackjack allows for more effective card counting techniques. Since there is only one deck, players can track which cards have been played more easily, allowing them to adjust their betting and playing strategies accordingly.
Fewer Busted Cards
Compared to double-deck games, there are fewer cards that can contribute to a player busting, providing an advantage when attempting to approach 21 without going over.
While single-deck blackjack presents several advantages for players, it is important to remember that the dealer also has rules that may impact gameplay (such as when they must hit or stand), and the element of luck and optimal strategy always plays a role. Moreover, players must still practice skill and discipline to maximize their chances of success.
When To Take Insurance With Single-Deck Blackjack
Deciding whether to take insurance involves counting. It pays 2-1, and there are 41 cards remaining if you play five seats. If more than 13 of them are tens, then you should take the insurance bet. So, if you have seen only one or two tens, then it is right to take insurance.
The maximum number of tens on the table for it to be correct to take insurance depends on the number of seats playing, according to the following table:
| Seats | Tens |
|---|---|
| 1 | – |
| 2 | 0 |
| 3 | 0 |
| 4 | 1 |
| 5 | 2 |
If you are playing 2 or 3 seats, if you can see no ten on the table, then you should take insurance.
Counting Cards In Single Deck Blackjack
Every online single-deck game I have seen – and I have looked at over 140 online casinos who have welcome offers (most for slots) – shuffle after every hand, making it imporssible to keep a running count.
If you think you can count, then there are many live-dealer single-deck blackjack tables with six or more decks dealt from a shoe, which give the counter an edge, and that would be the subject of another article.
In Las Vegas, however, the couple of remaining single-deck games I have seen shuffle after about half a deck, and counting is relevant to the second and subsequent hands.
The casino may well ask customers to leave, however, if they increase their bet dramatically when the count is high. But this is true of the multitude of blackjack games.

Choosing An Online Casino For Single Deck Blackjack
It is very important to play only at reputable licensed casinos. Taking advantage of offers to join, and then playing single-deck blackjack correctly, gives you every chance to come out ahead over the house edge.
But, if there is a danger of not being paid, you want to avoid the site. Often bonuses seem too good to be true, and you should read the terms carefully, but more importantly, only play at top-rated casinos.
I did not find any single-deck play games using the increasingly popular live-dealer method in which the cards are dealt with a shoe and shuffled in full view of the players.
This is partly because the cards would have to be shuffled after each hand, or the player would have a clear advantage, and this takes time. Secondly, it requires a dealer all the time which costs money. Playing more than one deal without a shuffle gives the player a significant advantage.
If you follow even just one principle, that should be to play only games that offer the fairer odds of 3 to 2 for blackjack. Offering 6 to 5 adds around 1.3% to the casino edge.
Terms and Conditions
It is important to read the terms and conditions before signing up for a site which gives a welcome bonus, typically 100% of the amount you deposit. You would normally have to play through the bonus 35 times or more before you can withdraw your winnings.
Most sites also assign a percentage contribution to each game, and blackjack is usually 10% or 0%. If the latter, and you don’t want to play online slots or scratchcards, then you can look elsewhere.
Of course, you don’t have to take the bonus, but if you want to play a lot, then choose the site with the best bonus terms.
Best Single-Deck Blackjack Casino
Pride of place must go to HippodromeOnline.com. It took me 43 seconds to open an account and no time at all to find the single-deck blackjack games on there. Both were by Microgaming. The five-seat game offers a slightly higher return:
One game had a single seat and another allowed play on up to five seats. They claimed a return to player of 99.7%, with perfect play. This tallies with simulations on my software Diable, which gives 99.81%.
Both games have the same rules: Dealer peeks on tens or aces, no double after split, doubles only on 9, 10 and 11, and dealer must hit soft 17. This appears to be common for Microgaming.

Live Single Deck Blackjack In Vegas
Only two casinos were offering a single-deck game in Las Vegas, in October when I went for G2E, the International Casino Exhibition, in October.
One was El Cortez in Downtown Vegas, at 600 E Fremont Street. Their website now says that they only offer double-deck however.
Silverton Casino Lodge, 3333 Blue Diamond Road, has single-deck blackjack and both El Cortez and Silverton pay 3 to 2 for Blackjack. This is the first question to ask, as paying 6 to 5 is very hard to beat. Someone on a forum claimed that Silverton had gone to 6 to 5, but I cannot verify that.
There is certainly a single-deck game in land-based casinos in West Wendover, Nevada, and, like a remote beach, this city has not been discovered by that many players yet!
Single-deck games are also offered at some Indian casinos on reservations. Atlantic City does not have a single-deck game of which I am aware.
I am a member of many casinos in the UK (apart from one that excluded me!) and am not aware of any single-deck games. Two-deck games are common in European casinos, but again I do not know of any single-deck games.
Cheat Sheet for Microgaming Single-Deck Game
(Hole Card, Dealer Peeks, Dealer Hits Soft17, Double Hard 9-11 Only, No Double after Split, One Card to Split Aces)
*13 v 2 is a stand, whatever the composition, although Wizard thinks 10-3 v a 2 is a hit. Some three or four-card totals can be slightly different, but the error would be tiny.
