What is Double Deck Blackjack?

Double Deck Blackjack is a popular variation of the classic blackjack game played with only two decks of cards. This variation offers a unique blend of strategy and excitement, making it a favorite among experienced players.

In double-deck game, the rules and objectives remain the same: players aim to get a hand value as close to 21 as possible without exceeding it, while also beating the dealer’s hand. However, the use of only two decks introduces several strategic differences compared to games played with six or eight decks.

Double Deck Blackjack rules & strategy

When transitioning from a six- or eight-deck game to double-deck game, strategy adjustments are crucial. Let’s explore these changes under two scenarios: when the dealer must stand on soft 17 (S17) or hit soft 17 (H17).

If playing rules are S17 and Doubling After pair Splitting (DAS)

For a Double Deck Blackjack where the dealer stands on soft 17 and doubling after pair splitting (DAS) is allowed, implement these strategy changes:

  • Double on a hard 9 versus a dealer’s 2.
  • Double on a hard 11 against a dealer’s ace.
  • Split 6-6 against a dealer 7.
  • Split 7-7 against a dealer 8.

If the Double Deck rules require hitting on soft 17 and allow double after split

When the dealer hits on soft 17 (H17) and double after split is allowed, incorporate these adjustments to the S17 strategy:

  • Double on A-3 (soft 14) versus a dealer’s 4.
  • Double on A-7 (soft 18) versus a dealer’s 2.
  • Double on A-8 (soft 19) versus a dealer’s 6.

By incorporating these strategies, you can face the lowest house edge: -0.18% for S17/DAS and -0.38% for H17/DAS.

  • Tip: Before playing any double-deck game, check the Blackjack rules and payoffs. Avoid games that pay only 6-5 for a Blackjack or don’t allow doubling down after pair splitting. 

Prefer games where Blackjack pays 3-2, DAS is allowed, and the dealer stands on soft 17 (S17). If H17 rules apply, it’s still acceptable but less favorable.

Counting cards in Double Deck Blackjack

Card counting in double-deck game requires several adjustments to your betting strategy. The primary differences between counting in a double-deck game versus a six-deck game include:

  • The true count fluctuates more often.
  • You’ll be playing more hands where you have the edge.

In a six-deck game, card counters must be patient, as it often takes several rounds after a shuffle for the count to become positive. This is when the edge swings in their favor, prompting increased bets. 

Sometimes, the count may never go positive during an entire six-deck shoe. However, once the count does go positive, it often remains positive for several rounds, allowing for substantial betting.

In contrast, the true count in double-deck game is more volatile. It can quickly go positive after just a round or two, but it can also drop into negative territory just as swiftly. 

Because you’ll encounter more hands where you have the edge, a smaller bet spread is required compared to a six-deck game.

While a 1-10 or 1-12 spread is needed for a six-deck game to maintain a respectable edge, a 1-6 or 1-8 spread often suffices for Double Deck Blackjack.

  • Penetration:
    • Penetration, or the percentage of cards dealt before shuffling, is crucial in double-deck game.
    • Many casinos place the cut card at 50%, meaning the decks are shuffled after one deck is played.
    • A game with 50% penetration is less profitable for card counters compared to one with 60% to 75% penetration (1.2 to 1.5 decks played).
    • Ensuring penetration greater than 50% is essential for card counters.
  • Additional tip:
    • With only 104 cards in play, a few extra cards dealt before shuffling can significantly increase your advantage.
    • If the count is positive and the next round is the last before the shuffle, spread and play two or three spots.
    • This strategy allows you to play more hands with an edge while consuming more undealt cards, resulting in deeper penetration.
    • Avoid using this tactic at the end of every positive deal to prevent attracting attention from pit supervisors.

Double Deck Blackjack odds & payouts

Double Deck Blackjack stands out as one of the best variations of blackjack available to gamblers. The primary reason lies in the favorable math:

  • The house edge in Double Deck Blackjack is approximately 0.34%, but it can drop below 0.25% under optimal conditions.
  • This edge depends significantly on the game’s rules. With a player using basic strategy and making correct decisions, the house edge can be better than 0.34%.

However, not all Double Deck Blackjack games are created equal. Some games can have a house edge exceeding 1.80%, which is far less favorable for the player.

When more decks are added to the game, the odds decrease for the player. Six- and eight-deck games typically employ automatic shufflers, further reducing the player’s advantage. In an eight-deck game, the house edge can surpass 2%.
