How Many Decks in Blackjack? Tips for Different Variations
Having multiple cards in a deck is now a common and standard practice in casinos. You can learn how to play live blackjack in a few steps.
Card Decks in Blackjack
Blackjack: how many decks originally? Casinos initially offered the classic single-deck blackjack. Before mathematician Edward O. Thorp published his popular book, “Beat the Dealer,” in the 1960s, advantage play in blackjack had a limited understanding. However, the book arrived and popularized card counting as a winning blackjack strategy.
The blackjack strategy reduces the house edge by teaching players how to keep track of dealt and undealt cards. And using a single-card deck puts the casinos at a greater disadvantage because it simplifies card counting. The casino’s only solution to regain balance was to increase the number of card decks.
Multi-deck blackjack makes it difficult for players to count cards. The cards are placed in a blackjack card shoe. The device also makes it more challenging to predict high and low cards while eliminating the need for constant reshuffling of cards.

Single-deck blackjack
How many cards in a blackjack deck? Single-deck blackjack contains the 52 standard playing cards. These few cards in play improve the odds of receiving favorable hands. It is also favorable for card counters as they can quickly and effectively take note of the cards the dealer distributes. You only have to assign values to each card and adjust your bets according to your count.
The main advantage of a single-deck blackjack is its lower house edge ( 0.5%), which can be reduced to 0.15% using strategies. Learn how to play American blackjack to stretch out your fun!
Multi-Deck Blackjack Variations
How many decks of cards in blackjack? The number of card decks used in multi-deck blackjack varies between two to eight. The higher it is, the higher the blackjack number of cards. The double-deck (74 cards), six-deck (312 cards), and eight-deck (416 cards) blackjack variations are the most common in casinos. More deck numbers, up to 12, are also available in some others.
However, all you need to know about blackjack online betting is the same for single-deck and multi-deck blackjack in terms of the gaming objective, which is to achieve a hand value of 21 or near enough, but not to go over it. Gameplay only becomes more complex due to the higher number of cards to manage.
Spanish Blackjack.
A less common version of the 21-card game is Spanish Blackjack. This variant uses a deck containing 48 cards (all 10s are removed) and a special table.
Impact of Blackjack Decks on Odds and House Edge
Single-Deck Blackjack
The chances of being dealt an Ace and a 10-value card are higher in a single-deck blackjack. As mentioned, the house edge can go as low as 0.15%. This means you have higher winning odds in this variation.
Multi-Deck Blackjack
Multi-deck Blackjack has a slightly higher house edge than the single-deck variation at optimal play. A 2-deck blackjack game has a house edge of 0.20% to 0.40%. A 4-deck game has a house edge ranging from 0.30% to 0.50%. In a 6-deck game, you can expect a house edge of approximately 0.40% to 0.60%. An 8-deck game often has a house edge of 0.50% to 0.70%.
Due to these higher house edges, favorable outcomes can be more challenging to get; either way, it’s always good to know how to play double-deck blackjack, since it’s the most common one.
Single vs. Multi-Deck Blackjack Strategies
The optimal strategy used for a single deck becomes much less effective with an increasing number of decks, meaning you have to adjust accordingly.
Adjusting Basic Strategy
The blackjack basic strategy chart shows when to take actions like doubling down, standing, hitting, and splitting on soft hands, which are great for a single-deck game. However, you may need a more conservative approach when playing multi-deck variations.
For example, it is good to double down on a soft 17 (Ace-6) when facing a dealer’s upcard of three to six in a single-deck game. However, in an eight deck game, you may want to avoid this move.
Betting Approach Differences
Adapting your betting strategy to the number of decks in play is also vital to your success. In single-deck games, you can increase your bets during favorable counts and when the deck is to your advantage. However, bet management becomes more intense in multi-deck games where card counting can be less effective.
Assessing Risk and Reward
Always balance risk and reward as you switch between single and multi-deck blackjack. For instance, where you wager $100 for single-deck blackjack, you want to wager $10 on a multi-deck table.
In a Nutshell
How many decks in blackjack? One for single deck and two to eight for multi-deck games. The variation for you is the one that fits your personal preferences, goals, and bankroll. Also, the odds, house edges, and strategies are factors you should consider when opting for a single or multi-deck table.
