How Many Decks In Blackjack

Blackjack is a card game that can be played with a single or multiple decks of cards. Historically, blackjack was always played with a single deck but this quickly changed with the birth and democratization of card counting.

Blackjack in Las Vegas can use one to eight decks. How many decks may not make any difference to a beginner player who knows just knows and plays basic strategy without paying attention to the cards played. However, the main thing you need to pay attention to is the rules of the specific table AND blackjack payouts. To know how many decks of cards do casinos use for blackjack also depends on the number of decks that the players will use different games, if most players are playing 8 deck blackjack games, then more cards will be used than how many decks in casino blackjack compared to users who use single decks Most casinos claim to offer single-deck games. Just to give you an example, suppose you are playing blackjack with eight decks and have reached a running count of +8 while there are four undealt decks in the shoe. In this case, the true count is equal to +8/4 = +2. If the running count is negative, say -8, so will be the true count (in this case -8/4= -2). Any blackjack game with more than 2 decks will be dealt from a shoe. Shoe games are completely beatable by card counting. The increased number of decks DOES decrease the advantage of the game, but that is often counterbalanced by other factors like better rules and more tolerance.

In fact, the numbers of decks used in a game, which can of course vary, affect factors like the house edge and the basic strategy to follow. So, let’s find out more about the decks used in blackjack.

How Many Cards Are Used In Blackjack

A single deck of cards used to play blackjack contains 52 cards. Among these, the cards, two to ten have their respective values that are, 2 to 10. The aces can be worth 1 o 11 depending on the game. The face cards, which are the King, Queen, and Jack, have a value of 10. The sum of the cards’ value is a player’s “hand value”. Since blackjack is all about numbers and the quest to achieve 21, the ace and the face cards are of high significance, a combination of two of which is also quite sought after in the game.

Once the initial cards are dealt, players can opt for additional cards, place side bets and the game goes on. Modern blackjack is seldom played with a single deck of cards, whether in land-based casinos or online. At least six to eight decks of cards are used leading to a game of about 416 cards and 96 face cards, shuffled and reshuffled well for each round of blackjack.

Technically, there is no restriction or upper limit to how many decks of cards can be used in blackjack. However, the more the number of cards, the greater is the complexity of the game. Modern blackjack, as played in most land-based casinos from Las Vegas to Macau, uses six to eight decks of the standard 52 playing cards. In fact, depending on the number of decks used, many Las Vegas casinos have introduced several interesting variants of this card game.

It is necessary to remember that a higher number of decks in a game increases the house edge. The standard house edge in blackjack, which is considered to be 0.5%, applies only when a single deck game is played with player-friendly rules in place. Card counting also becomes difficult in a six to eight deck blackjack.

How Many Decks of Cards Are Used In Online Blackjack

In online blackjack, games are generally played with up to eight decks of cards. Additionally, some online casinos may shuffle a single deck automatically at every hand. Virtually, this means you cannot count cards whatsoever in online blackjack.

This computerized reshuffling at each round leads to a randomization of the cards, making it difficult for card counters to implement a solid blackjack strategy.

Wondering why online blackjack sites do that? As we know, every deck of cards has a predetermined amount of cards with fixed values. As such, the aces are 1 or 11 and the face cards that are Kings, Queens, and Jacks are 10. These two varieties are the most important cards for a player to get a blackjack.

Now, when at least six decks of cards are so automatically shuffled and randomized, as it happens in online casinos, there are 96 of these high-value cards. Out of these, landing up with a strong 2-card hand that is blackjack or close to 21 becomes difficult. Online blackjack played with multiple decks, as a result, significantly increases the house edge.

Live dealer blackjack is streamed online but players get the feel of being in a real casino because of the live dealer initiating the game. About 8 decks of cards are used in live dealer blackjack, much like in the land-based casinos. Some live dealer blackjack games are played with six decks also.

There are a few deck related rules followed in live dealer blackjack to ensure a fair game for all. For instance, the shoe penetration is 50% of the shoe and also, the same is changed after only 4 decks have been dealt. On some tables, auto shuffling is facilitated. Most importantly, the cards are burned, that is, the top card or the face-down cards from the deck are removed before the hands are dealt. This burning takes place either at the beginning of the shoe or at some points before each new game round.
