How many decks in Blackjack

Are you curious to give Blackjack a try? Here’s what you need to know about the gameplay and how the rules influence the house edge.

The main aim of our guide

One of the most critical factors impacting Blackjack is the number of decks used. Not only can it affect your house edge, but it can also determine the success of your strategy and payout limit. That’s why knowing this information is essential before you play it for real money.

Standard Blackjack decks of cards range from one to eight. However, finding a UK casino site offering games with a higher number of decks wouldn’t be out of place.

While people play a random game of 21 with one or two packs at home, land-based and online casinos usually feature tables with six to eight packs of 52 playing cards.

Although single deck variations still exist, they aren’t as common as six or eight-deck games, which have fast become the industry’s standard number of decks.

Like brick and mortar versions, online Blackjack games usually feature between six to eight decks of cards. However, you will still find single-deck options available at some internet casinos.

The plus side of single-deck Blackjack

One of the reasons players love playing single-deck games is because it aids in card counting. With only one deck, you can easily calculate the remaining cards and use them to your advantage.

However, it is challenging to apply this method online because the Random Number Generators (RNGs) casino sites use it to automatically shuffle their cards. 

Playing single-deck or multi-deck 21 variations online still opens you to several perks and favourable house edges.
