Blackjack games are among the most popular activities when it comes to (online) gambling. Each one of us will at least know about the crucial number 21, even though not everyone will be familiar with the actual Blackjack game rules. Casino games like Blackjack are not unified likewise and can show their face in all forms and variations. Actually, nowadays playing Blackjack is quite different from what it used to be in the past. One of those major changes is the ongoing disappearance of single-deck Blackjack games.

Easy enough to grasp that a single-deck Blackjack game is played with just one deck. Meaning that fewer cards overall are part of the shoe (if there is a shoe even). To be more precise, single-deck Blackjack contains 52 cards all in all. A single-deck game just like any other Blackjack game includes 2s to 10s with their respective value, face cards (Jacks, Queens, and Kings) which are also worth 10 as well as Aces which can either show a value of 1 or 11. Let us, first of all, find out why single-deck Blackjack games are not common anymore!

The Demise of Single-Deck Games

As every experienced Blackjack player will know, single-deck Blackjack used to be the big thing back in the day. Their clear advantage was that they offered a very low house edge which could go down to just 0.15%. This of course sparked the interest of Blackjack players using optimal strategy. Also playing single-deck Blackjack made it easy and convenient for card counters to have a running count and turn the tides towards player advantage.

Card counting is basically the act of attaching a value of each and every card within the deck starting with the dealt hand. Values can be either +1, 0, or +1. Counting cards is accordingly played upon the statistical evidence that high-value cards (every picture card, aces, 10s, and 9s) are more beneficial for the player.

Contrarily, lower-valued cards such as 2s to 7s are considered helpful for the Blackjack dealer. You can read more about this Blackjack strategy of card counting  in our following article around the subject of how to count cards, and more.

Casinos were aware of this though and went on to change the structure of decks. The lowest house edge was now replaced by double-deck and furthermore multi-deck Blackjack games. This was happening in order to both prevent card counting to be as non-complicated as before and also to increase the house edge once more.

This also occurred in online casinos which either way shuffled the deck before every new hand. A running count was made hard to follow up on in any case under those circumstances.

 

More Decks counteract the Lowest House Edges

Instead of single-deck Blackjack, many casinos all over the world started to commonly capitalize on six to eight decks. Multiple decks complicate matters for sure.

Not only do the remaining cards increase with each additional deck but multiple-deck Blackjack also fosters the house edge. Additionally, the payouts in single-deck Blackjack were usually 6:5. Meanwhile, multi-deck Blackjack cuts this down to 3:2. 

Online Blackjack even stirs up the ingredient of automated shuffling after each hand. Both the computerized version and also live dealer Blackjack use up to eight decks.

Any type of Blackjack strategy becomes harder and harder with those multi-deck games. Only one deck was a delight for pretty much every type of Blackjack player but a multi-deck game needs more investment in each sense.

 

Single-Deck Blackjack House Edge

As we already mentioned beforehand, single-deck Blackjack offers a house edge of only 0.15%. This circumstance aligns with the casino rules nonetheless. Since this is not just a matter of how many decks are actually played at this specific moment. The specific rules which have an influence on the house edge are:

  • Dealer hits on soft 17 vs. dealer stands on soft 17 (the latter reduces the house edge)
  • Pair splitting is only allowed once vs. re-split
  • Double down rules: You can double down after a split vs. you cannot (the latter increases the house edge)
  • You are allowed to surrender vs. you are not allowed to surrender
  • Payouts of Blackjack variations

The Best Single-Deck Blackjack Strategy

Blackjack Charts

In order to read the Blackjack strategy chart, you analyze the vertical line as your own first two dealt cards. The horizontal line on the other hand is the dealer’s up-card.

The single-deck Blackjack chart also both deals with hard totals (no Ace is established within the first two cards) and soft totals (an Ace with the value 11 is included in the player’s hand).

Additionally, you will discover suggestions on when to split or hit if you have two of the same cards in your hand.

Keep in mind that 10s are left out of the equation since it is not always aligned whether you can split ten-valued cards in general or only ten-valued cards of the same rank. Like for example a pair of Jacks but not a Queen and a Jack.

  • on a hard total of 9, you should double down vs. dealer’s up-card 2-6. If this is not possible, then you should hit. Other than that hitting is the preferable option.
  • on a hard 10, you should double down vs. dealer’s upcard 2-9. If not applicable, always hit also in cases beyond this.
