Decks: How many packs of cards are used in blackjack? - July 10, 2025

The fewer decks there are, the better your Odds.

Well, sort of. However, it's easier to keep track of the tens and face cards that were in play when there are fewer decks in play, and it's good to use this knowledge to your advantage.

Genau wie zu Hause können Sie einen Tisch finden, an dem nur ein Kartenspiel verwendet wird, aber in einem Live casino ist es viel üblicher, dass sechs bis acht Maps im Spiel sind. Das Same gilt für Online-Plattformen wie TwinSpires Casino.

For most of us, it hardly makes a difference. We still get two cards, see what the dealer's face up card is, and then we can play our hand in the usual way. There's nothing strategically that you should do differently, except maybe try to keep track of the number of tens and face cards that have been in play.

Why casinos change the number of decks in blackjack

There are two good reasons why casinos prefer to play six to eight packs of cards at a time. Blackjack table to use.

Firstly, in a game with only one deck, the dealer has to reshuffle the cards after each round, and that takes time. And as you probably know, this is the time when the casino is not making money. A casino that doesn't make money is not a good business (at least not for the casino owner). However, if there are six to eight decks in play, you can play many hands of blackjack before the dealer has to shuffle the decks again.

The second reason why the number of packs of cards is so important in blackjack is that the House advantage is always slightly better in games with more packs of cards. One reason for this is that it is much more difficult for the players at the table to keep track of the cards they have seen. For you and me, card counting is not illegal, but it is frowned upon by casinos.

If you are playing with several decks, you will notice that the dealer cuts the cards with a blank coloured card before placing them all in the shoe. Therefore, not all the cards are used in the game, because as soon as the dealer gets to the cut card, the decks are reshuffled. So not only do you have to keep track of more cards between shuffles, but you also don't know how many tens or face cards are in play.


Decks in blackjack: One, four, eight or more?

Das kommt darauf an. Ein und vier Decks sind nicht gerade die Standardvarianten. Und selbst wenn sie es sind – die Karten werden vielleicht oft gemischt, aber auch das ist nicht unbedingt von Nachteil für Sie. Die meisten Kasinos halten jedoch acht Karten für einen guten Richtwert. Damit haben sie einen fairen Hausvorteil und bieten den Spielern eine Chance, trotzdem zu win. Dies und die Tatsache, dass Blackjack eine der höchsten Payments ensure a perfect gaming experience.

In the case of eight decks, many cards come into play at these tables. If you want to improve your chances, you need to keep track of 516 cards. While it's true that counting cards and being very good at it will most likely result in the casino escorting you out of the room, it's not illegal and it's perfectly fine to do your best. In fact, every croupier knows you're trying.

More decks mean a slightly better house edge for the casino. Of course, casinos use up cards in blackjack, and dealers can reshuffle the cards if they feel you are catching up on the number of cards in the deck too quickly. Overall, however, blackjack is considered a fair game and there is nothing to make you feel insecure as a player. However, if you want to minimise the process, it's better to focus on fewer decks. At least when it comes to land-based blackjack.

Does this mean that a blackjack with only one deck is always the best? That all depends. Casinos are also smart and know that you might just be sitting on the sidelines counting the cards. That's why some casinos won't let you play until the cards are played through or when the cards are reshuffled. The betting areas can also be limited at such tables. Again, there is nothing inherently unfair here, and blackjack remains one of the best and most balanced games. In Las Vegas the house edge is 0.5 % to 0.8 %.

Online Blackjack: Does the number of decks matter?

One fact you may not have realised is that the number of decks doesn't really matter in online gambling. Why is that? Because online casinos have a so-called Random number generator (RNG), which reshuffles the cards after each issue. What happens here is slightly different and not exactly a shuffle, but it still counts as such and has exactly the same effect.

The game simply draws cards at random from the number of decks you have selected to play, and sets them back after each betting round. You can't use your knowledge of card counting online and therefore shouldn't worry about the number of decks. Instead, concentrate on the betting limits and any additional features that are important to you, and that's it. But here's the big secret: as long as you don't count cards, shuffling the deck is always in your favour - whether you're playing in a land-based casino or online.


Play blackjack, um Spaß zu haben
Regardless of which blackjack variant you choose and no matter how many packs of cards are used, you should always remember that blackjack is all about one thing: having fun. Regardless of which option you ultimately choose, you should focus on the things that are important to you - which in the end are Rule the amount of the stakes and all side bets that you can place at the same time.
