In order to determine how profitable this type of the game can be, it’s important to make a double deck blackjack vs 6 deck comparison. In the paragraphs below we highlight the advantages and shortcomings of each game and teach you how to beat double deck blackjack.

Generally speaking, the fewer decks in play, the better the odds are for blackjack players. This isn’t all about double deck blackjack card counting, which is obviously easier when there are few cards to keep track of. The main reason is that the frequency of two card 21 is higher if you play with just two decks. Since blackjack pays 3 to 2 at the best double deck blackjack in Vegas, this game can be profitable.

Only the player gets boosted profits for hitting blackjack, so you have an advantage over the dealer. Unfortunately, most casinos will only pay 6 to 5 on blackjack, which greatly reduces the long term winnings and makes the six deck version better. To determine which games are worth playing, try the free double deck blackjack at your casino of choice and pay close attention to the pay tables.

A profitable online blackjack strategy for double deck blackjack needs to factor in other elements. If the dealer stands at soft 17 and you are allowed to split any pairs, including aces, the game is worth trying.

Double deck blackjack tips and strategy

Playing double deck blackjack online is a relatively straightforward process, because the rules of the game are easy to learn and master. To be truly successful, you should first understand the double deck blackjack odds and use a blackjack cheat sheet to hit and stand correctly. In the paragraphs below, we take a closer look at the standard double deck blackjack strategy to help you improve the odds of winning.


👉 The first and most important thing to mention is that you should never take insurance at double deck blackjack casinos. It is a bankrupt strategy in the long run because the odds are stacked against you.

👉 Surrendering is generally a bad idea, but you can use it if your cards totals are 15 or 16 and the dealer has an ace. If the dealer hits on soft 17, you can also consider surrendering with a hand total of 17. You can find more in our “When to surrender in blackjack” guide.

👉 The best double deck blackjack strategy will require you to use a blackjack chart indicating when to hit and stand. Generally speaking, you should always stand at 12, 13, 14, 15 and 16 if the dealer shows a low card ranging from 2 to 6. Hitting is always recommended when you have an ace and a low card from 2 to 6, and double against the dealer showing a 5 or 6

👉  When to double down in blackjack is an important question that must be answered when playing double deck blackjack. You should always do it when your first two cards amount to 11 and double on a ten if the dealer shows anything but a ten or an ace. The same goes for splitting pairs of 8 or 9 if the game allows you and the dealer shows a 4, 5 or 6.

Card counting in double deck blackjack

When players try to figure out how to win double deck blackjack they immediately think of counting cards. It makes sense to consider this possibility, since fewer decks are in play and it should be easier to count. The ability to keep track of the cards that were already dealt can help you make the right decisions for the remaining hands. In conjunction with solid bankroll management, this allows you to double down when the odds of making blackjack are better, so the house edge is decreased.

However, this can only work in land-based casinos and game parlors, assuming the dealers and pit bosses are not careful. That’s because these casinos don’t reshuffle the decks after each hand, like their online counterparts. When this happens, it doesn’t matter if you are capable of keeping track of the cards dealt, as software will render your progress irrelevant. Instead of trying to beat the house edge in this way, you should try to master double deck blackjack strategy.

Best Las Vegas double deck blackjack games

Some of the best double deck blackjack games can be found online, but Las Vegas casinos have pretty strong games themselves. In order to find the very best game in town you should focus on some key elements.

♠️ First of all, you should always focus on games that will pay 3 to 2 on blackjack. These offer the best return to player while 6 to 5 games carry a high house edge that is crippling in the long run.

♠️ Equally important is for the dealer to stand on all 17 totals, soft and hard. Right from the start, you would reduce the house edge to 0.22%, which in the long run can make the difference between profits and losses.

♠️ The best Las Vegas double deck blackjack games will allow you to double down after splitting pairs, aces included. This reduces the house edge by an additional 0.11%, which is another big gain.

♠️ Insurance should never be considered, so it is irrelevant if the Las Vegas blackjack game offers it or not. On the other hand, it is useful to have a late surrender version, although this is a rarity at games using two decks. Although this option should be used rarely, it allows you to recuperate half of your stakes when your hand is speed against crushing odds.

  • Players can count cards if the decks are not reshuffled
