Best Online Blackjack UK Sites in 2025 – Classic, European, Spanish 21

This version of blackjack is usually played with one to eight decks. Both you and the dealer get two cards each. If the dealer gets a soft 17, they are required to stand. Similarly, you can decide what you want to do with your hand based on the card values. However, remember that this version of blackjack doesn’t allow you to make any side bets, meaning you can focus on the main gameplay.

Instead of up to eight decks, this version of blackjack requires only two decks. When the croupier deals the cards, they receive only one card that is face up. Based on the value of this card, you can determine whether it’s wise to up the ante or if you would want to surrender the hand.

A version of blackjack that’s quite common, Vegas Strip requires four decks to make the gameplay work. Similar to classic blackjack tables, the dealer will stand on a soft 17, while you are allowed to decide whether you want to double down, split, or resplit as cards are revealed.

Another interesting version of this popular table, Spanish 21 blackjack requires between 6 and 8 decks. Instead of using the entire deck, you’ll find that 10s are eliminated, while the face cards get values of 10 each, just like in classic blackjack. In addition to standard rules, you can also decide to surrender the hand late, while you can split your cards more than once to try and form a winning hand.

Depending on the type of blackjack table you choose to focus on, you can come across various rules. It’s essential to look into these specifics before you start wagering so that you don’t risk making bets that are not allowed. Here are some of the blackjack rules that you should know:

• Atlantic City Blackjack: In this version of the game, you play with eight decks but are required to stand on a soft 17. If you don’t have this specific hand, you can decide to split, resplit, double down after splitting your cards, or do a late surrender if you can’t form a good hand.
• Single Deck Blackjack: This version has one of the lowest house edges, making it highly suitable for newbie players who don’t want to risk significant losses. However, this feature makes it quite rare in online casinos.
• Double Deck Blackjack: You can play this version of blackjack with two decks, which means that you will enjoy a higher player advantage than when playing with 6 or 8 decks.

Considering the popularity of blackjack, some casinos choose to offer additional versions besides the highly popular versions we’ve mentioned thus far. Some of the games you should definitely look into include:

• Blackjack Switch: In this version, you are dealt two hands with two cards each. Depending on the specific cards, you can choose which hand you want to use, while you can also switch top cards between hands.
• Zappit Blackjack: One of the more flexible versions of the game, this type of blackjack includes the rule that hands with values between 15 and 18 can be entirely replaced by the croupier if the player decides they don’t want to play with their cards.
• Perfect Pairs Blackjack: This version often includes making side bets, which can be mixed pairs, colored pairs, or perfect pairs. This means that you are betting on cards of the same rank, same color, or cards that are entirely the same, forming a perfect pair.
• 21+3 Blackjack: A combination between a blackjack hand and a 3-card poker hand. This is one of the harder versions to master because you also need knowledge on poker hands and values.
