Blackjack is a popular casino game because it has a low house edge and interesting gameplay. Your choices can impact the game. While having a good strategy helps, the casino’s rules can make it harder to win, often giving the casino an advantage.
One way casinos increase their edge is by using more card decks. The more decks there are, the harder it is to win. That’s why many blackjack games use six or eight decks.
So, how many decks are used in blackjack? We’ll answer that and explain why casinos use multiple decks and how multi-deck games differ from single-deck games.
Blackjack rules don’t limit how many decks can be used; theoretically, you could have as many decks as you want if you have a big enough “shoe” to shuffle them.
In practice, casinos usually use up to eight decks for blackjack. Using more than eight decks would be impractical because you’d need huge “shoes” and big tables for all the cards and players.
Casinos often use four, six, or up to eight 52-card decks for blackjack. With more decks, the odds change, so it’s important to understand how the number of decks affects the game.
Casinos use more decks in blackjack for several reasons:
Single-deck blackjack, also known as pitch blackjack, is rare because its low house edge makes it too favorable for players. In single-deck games, players can use card counting and strategy charts to have a better chance of winning.
To balance this advantage, casinos usually add stricter rules for single-deck games. For example, while a natural blackjack (a 10 and an Ace) typically pays 3 to 2 in multi-deck games, it pays only 6 to 5 in single-deck games. This changes the house edge to 1.39%.
You’ll mostly find multiple-deck blackjack at casinos, both online and in person. Casinos use multiple decks to make it harder for players to keep track of the cards, which helps them make more money and keeps the game exciting.
Most casinos use six or eight decks because these setups give the casino the highest advantage (0.64% and 0.66%, respectively) and have the most cards (312 and 416). This setup makes it tougher for players to count cards and manage their budget.
Four-deck blackjack is a bit better for players because it has a lower house edge (with 208 cards to keep track of). However, it’s less common, so it’s worth looking for.
In Atlantic City, casinos must be careful about skilled players because they can’t ban them just for card counting. Instead, casinos use more decks to protect themselves.
Most Atlantic City casinos use six or eight decks, which increases the house edge. For example:
With six or eight decks, the house edge is more than double that of a single deck, which helps casinos defend against skilled players.
Atlantic City also offers Spanish 21 more often, but not because it’s more generous. The house edge in Spanish 21 can be up to 4%, though expert players can sometimes reduce it to around 0.45% with a strong strategy.
Las Vegas provides a wide range of blackjack games. While single and double-deck games are less common, you can still find them if you look carefully. Most casinos will have six or eight-deck games, but some popular resorts might offer single-deck blackjack as well.
The types of games and their minimum bets vary depending on the casino & your budget. For example, at MGM Las Vegas, you can play:
It’s interesting to note that the minimum bet for single-deck blackjack is $15, which is the same as for six-deck games and lower than for double-deck games. This is because single-deck games often offer a lower payout for a natural blackjack (5 to 6) compared to the standard 3 to 2 payout for other games. This adjustment increases the house edge from 0.25% to 1.24%. So, it’s important to know the specific rules of the game you’re playing to avoid any surprises.
In online blackjack, it doesn’t matter much how many decks are used because the Random Number Generator (RNG) shuffles the cards after every hand. This means card counting won’t help you. Instead, focus on strategies like doubling down and splitting.
In live dealer blackjack games, casinos usually use 6 to 8 decks. This is because using multiple decks means there’s less shuffling, so the game keeps moving quickly. Some live tables might use just one deck with an automatic shuffler to keep things flowing smoothly.
While playing blackjack, remember:
In blackjack, your goal is to win against the dealer by getting as close to 21 as possible without going over. If you reach 21 or if the dealer goes over 21, you win. During the game, you can choose to stand, hit, double down, split, or sometimes surrender your hand. Some variations of the game also offer side bets and special rules to make it more interesting.
After you get your first two cards, you can choose from these four common actions:
Blackjack has one of the lowest house edges in online casino games, which is why it’s becoming as popular as poker and jackpot slots! However, it’s easy to get caught up in the fun, so it’s important to gamble responsibly. Set a budget & bet what you can afford to lose, and a time limit before you start playing.

In summary, the number of decks in blackjack affects the game’s rules and house edge. Single-deck games are best for players but are rare because they’re easier to count cards in. Multi-deck games are more common and give the casino a bigger advantage while making the game more complex. Knowing how many decks are used can help you plan your strategy and manage your expectations, whether you’re playing online or in a casino. Understanding this helps you make better decisions and enjoy the game more.
