The Basics of Online Blackjack

Online blackjack is a relatively simple game to understand once you learn the basics. What you should know before starting is that it’s a skill-based card game played between a player and a dealer. The dealer plays under a certain set of rules. The goal of blackjack players is to defeat the dealer by not busting their hand – or going over a count of 21. Playing blackjack at online casinos is easy as you can practise all you want with free blackjack variants. Here are some blackjack tips and strategies you can follow:

• Blackjack players will enjoy the fact you can play for free. Even as a blackjack beginner, this should give you a great idea of how the game works. A few rounds of blackjack and reading the rules guide and you’ll be ready to start. Of course, it takes a lot of practice to master blackjack, but beginners can learn the rules by heart with free practice or by playing with a casino bonus.
• At the beginning of each round, the dealer will deal two cards to themselves and you (the player). One of the cards will be face up, so you can have a better idea of how close the dealer is to a count of 21. Once the dealing is done, the player will decide to either compare hands, ask for another card to come closer to a count of 21, split their cards into two hands or double down if they have a favourable hand. After that, the hands will be compared and the winner declared.

Free online blackjack games will give you a pretty clear idea of what happens in the game of 21. You only need a bit of practice to understand the basics. The learning curve is not hard, especially as you progress. Applying a basic blackjack strategy is a good idea even for beginners that’ll help you learn more about the game.

How to Play Online Blackjack Games?

When playing online blackjack, the player on the left of the dealer will play first. The dealer will proceed to deal 2 face-up cards to the player, and 2 to themselves. One of the dealer’s cards is face-down, so you won’t see it until you’ve made your decision on what to do with your current hand.

When you’re ready to play blackjack online, you should think about what you do next. The best online blackjack strategies will tell you what to do in any situation. But, to make things easier for beginners, we’ll describe the initial steps below.

• Hit – you choose to receive another card from the Dealer in an attempt to take your hand value closer to 21 or hit 21 exactly.
• Stand – face the dealer’s total with your current total. The game will proceed to a hand comparison point where the winner is announced.
• Double Down – double your bet in the middle of a hand in return for one extra card. This option should only be used if you’re confident your hand will win.
• Split – turn your two cards into two separate hands before receiving one extra card for each hand.
• Surrender – surrender your hand and forfeit half of your bet to the dealer. You receive half of your bet back.

The only win condition in blackjack is that your hand is closer to 21 than the dealers. Once you’ve made your move, the dealer will reveal his down card, before continuing to draw cards until they go bust, or their hand totals 17 or over.Most blackjack variants follow a so-called Soft 17 rule. This means that the dealer either stands on a Soft 17 or higher or hits on that value. While you can do whatever you want with your hand, the dealer must follow strict rules, and this is one of them. The Soft 17 rule in use is usually written on the table. The usual return for a win against a dealer is even money. If you have a natural blackjack – an ace and a 10-card – you win 3:2 or 6:5 in some variants.

Card Values

Each card in online blackjack is identical to the face value shown on the card, with the exception of royals and aces. King, Queen and Jack are worth 10, while the ace will count 1 or 11. This is where soft and hard totals come into play. You can use them strategically to secure yourself a better hand if one of the cards in your hand is an ace – in this case, you have a soft hand then you’re believed to have a soft hand that can count as 1 or 11. If you have a hard hand, it means you have a hand without an ace or an ace that counts as 1. This heavily affects the way you play your hand. Here is a soft-hand example to make it more easy to understand:

• You receive an ace and an 8 after the dealing.
• The total count of the hand is now either 9 or 19. 

In this example, the player has a fairly strong hand against the dealer, no matter the dealer’s cards. If the player is happy with 19, then they stand against the dealer, who must stand on 17. Here’s an example of a hand where it won’t be beneficial to stand on a soft hand:

• You receive an ace and a 2. 
• The total of the hand is now either 3 or 13.

In this example, the player has a rather weak hand, but the presence of the ace makes things a bit better. The choice here would be to hit for another card to raise the total value, but there’s more of a safety net than there would be if you were dealt a hard 13. This is because the ace reverts to a value of 1 if the new card would cause the player to bust in normal circumstances. Let’s look at this example.

• You receive an ace and a 2. 
• The total of the hand is now either 3 or 13.
• The player decides to hit and gets a King.
• The total hand value is now hard 13. 

As you can see, the player isn’t bust as they’d normally be. The ace changes its value to 1, preventing a bust. The hand in this example is now a hard 13, and the player can hit for another card.

Splitting Pairs in Online Blackjack Games

Sometimes when you play blackjack online, you may get an opportunity to split your hand in to two. This means a double chance to win against the dealer. Of course, you shouldn’t just split any hand and you won’t be allowed to do so. Playing with two hands is a bit more complex than playing a single one, not to mention more expensive. The bet on the second hand must match the first one.

Once split, the two identical cards will become separate hands, and you’ll be able to stand or hit on each hand independently. Once you’ve stood or gone bust on one hand, then you may play the other. It might be tempting to split, but there are situations where you shouldn’t.

• Always split aces – in that way, you’ll have two great starting points.
• Never split 10’s as they offer great value firsthand.
• Split 9’s if the dealer’s total is 2-9, otherwise stand.
• Always Split 8’s.
• Split 7’s if the dealer’s total is 2-7, otherwise hit.
• Split 6’s if the dealer’s total is 2-6, otherwise hit. 

These are just some examples of what decisions to make with what hands, but how can you memorise it all? This is where blackjack strategies come in. We’re not talking about the complex strategies, but a basic one that can take your game to the next level.

Best Live Blackjack Sites For UK Players

The best live blackjack sites are right here on this page. Live blackjack games are getting a lot of attention and it’s no wonder why. They offer an immersive experience RNG blackjack variations can’t, while keeping the rules and specifics such as the house edge the same. Playing live blackjack online is almost the same as playing in brick-and-mortar casinos, and the fact it’s played in real time makes live online blackjack games even more attractive.

We strongly recommend you take a look at the Evolution Gaming live blackjack variations at the best live online casinos in the UK. They come in classic and exotic varieties with features such as multipliers or unlimited seats. We’ll break some of them down in the paragraphs below.

Variations of Live Blackjack Games

Let’s spice up your live blackjack experience, shall we? These unique variations promise an adrenaline rush like no other! Whether it’s the thrilling multipliers of Lightning Blackjack, the tempting Bonus Blackjack bets or the vibrant atmosphere of Multiplayer Live Blackjack, there’s plenty to keep you on the edge of your seat.

• Lightning Blackjack: Lightning Blackjack is an award-winning classic blackjack variant by Evolution Gaming. Just like Lightning Roulette, it introduces players to multiplier-boosted payouts for a truly unique experience at the table. In this variant, you’re always guaranteed an x2-x25 boosted on a winning score. Multipliers are also saved for the next round, so losses aren’t that hard if you win the next round. The house edge and rules remain the same, making it a suitable option for all blackjack players.
• Bonus Blackjack: Bonus blackjack is not a variant you can play with bonus funds. Almost all of them qualify for that. It’s a special variant with a standard house edge and gameplay, with the difference being in the Bonus bet. If you put your chips on it, you’re betting that either the dealer, you as a player or both receive a natural. If that happens, the player wins 15:1 regardless of the round outcome.
• Multiplayer Live Blackjack: Multiplayer live blackjack is exactly what it sounds. It allows for more players in a game, so you will wait your turn when you finish. It’s still a fast-paced variant of live blackjack you’ll find at the best blackjack site that follows traditional rules.

Online Blackjack Strategies

Playing blackjack online is best done with strategies. While on the subject of strategies, you’ve surely heard about the successful MIT blackjack team in the 1970s who made millions on the table. They used card counting to cheat their way to major wins. While card counting has been banned, you can use various strategies in a blackjack casino on the Internet to optimise your wins.

One thing about blackjack strategies – they can optimise your winning returns, but you can’t expect wins all the time. Despite the fact it’s a skill-based game, skill also plays a role when playing online blackjack. The good thing is that with a basic blackjack strategy or an advanced one, you can get the most out of your sessions at real money blackjack sites.

Basic Blackjack Strategy

A basic blackjack strategy isn’t a strategy per se. It’s more of a collection of Blackjack tips that will help you play each hand for optimal returns. This means memorising what you should do in each situation. Learning the hands by heart and learning when you should hit, stand, split or double down is the perfect basic strategy. You can also take a look at early payout blackjack tables to see what each situation requires.

With a simple blackjack strategy, you will be able to cut down the house edge from 1%-2% to 0.5%. That means a lot when playing blackjack online for real money. Cutting down the house edge means more successful returns per hand, and that’s why the basic blackjack strategy is a godsend for beginners.

If you have a basic blackjack strategy chart downloaded together with a chart, you can practise your moves on a free blackjack variant. This is something that you can’t do at land-based casinos. Visit any trusted real money blackjack site and try demos to practise your moves and learn how to play each hand perfectly.

Advanced Blackjack Strategies

When you master the game of blackjack, you will be able to play strategies that are a bit more advanced. There are many of those around and most are tied to the different blackjack variants. Of course, they work best when you play classic blackjack. Casino players with a better understanding of the game will resort to using advanced strategies to cut down the house edge and further improve their chances of winning each hand.

While there’s no guarantee that advanced strategies work, you can test them for free at most online casinos. This is highly recommended before you play real money blackjack. Below are the most popular advanced blackjack strategies, including a couple that can also be used on other casino games such as roulette.
