What Is Blackjack?

Also known as 21, Blackjack is one of the most popular casino games around and readily available at any online casino – virtually all reputable casinos will offer you the chance to take on the dealer and that will include playing for real money, where you can try your best to land some wins.

The game itself is you against the dealer as you try and get your card hand to as close to 21 as possible without going “bust” which means that your hand exceeds this number. Whilst it is straightforward to pick up, there are multiple things to consider before playing – and this page will help you on your way to become a better player.

There are different variations to the game. Each one will appeal to different players and blackjack casinos will push certain ones. Regardless, whether you prefer the authentic experience of live dealer or a more relaxed session against the computer, you will always have options. Below are five recommendations from Slotsia.

Blackjack Switch

In this instance, you are given two pairs of cards, which are dealt face-up, and you can improve your hand by switching if you choose to. In this instance, pay-outs for blackjack are 1:1 instead of 3:2.

Spanish 21

The main difference with Spanish 21 is that the ten cards are removed, meaning you are operating with a 48-card deck. That, in turn, increases the house edge. Another difference is that the dealer can look at their hole card.

Super Fun 21

Using only a single deck, the rules are like classic blackjack but there are different payment methods. Pleasingly for players, any time you have a natural blackjack, you will always beat the dealer. Plus, you can get a 2:1 return on a diamond blackjack.

Pontoon

As in Spanish 21, the 10 cards are removed from this game, whilst the terminology used is also different, but the way you actually play is similar to traditional blackjack.

3D Blackjack

While the rules and winning potential stay the same as any standard game of blackjack, the 3D element ensures that the game adds extra realism and lasts long in the memory.

This is undoubtedly the most popular game and it’s the one that most players will have come across, whether it’s online or in a land-based casino. Essentially, it’s played with up to eight decks and you and the dealer are initially given two cards, one of which is face down for the dealer. From there, it plays out as normal, with the aim to get 21, or as close to it as possible, and you can request additional cards if they’re needed.

Blackjack Bonus and Odds

generic blackjack

As you will be able to see already, there are plenty of reasons to play blackjack. It’s a game that will deliver tension, excitement and fun when you play – but it can get even better. That’s because you will be able to take advantage of a blackjack bonus when you sign up at a new casino

Whilst most welcome offers will not specify that they can be used for blackjack, the reality is that you can use them on casino games that you want, so they can be used on the table game. This could be as simple as a matched deposit, whilst certain casinos may offer specific blackjack bonuses, whether that’s to a new player or an existing one. The bonuses are always worth checking out as they can be an easy way for you to get off to a good start when you play. As always, though, check the terms and conditions before you take an offer.

How to Find the Best Blackjack Bonus Offers?

You can find the latest offers on various sites, which will allow you to compare which blackjack bonus is going to be ideally suited to your game. It’s crucial to note that different offers could suit different players depending on how often you’ll play the game. So, check the sites, compare, and pick the bonus that suits you; there are some great offers on this page. Everything you will need can be found online, so do your research first. 

Blackjack Odds Explained

Part of the attraction of blackjack is the fact it’s a simple game, both to play and to understand how you win. And, with a house edge of around 0.5-1.5%, it’s one of the better casino games around in terms of players trying to secure wins. 

Obviously, that still means the house should win over a longer period, but your chances are significantly better than if you played other games, such as slots. 

How to Play Blackjack Online for Free

You don’t have to play real money blackjack to experience why it is so popular. As mentioned, part of the thrill of the game is the suspense as you wait to see which card is turned over and the in-game decisions that you need to make. If you want to do that without risking cash, it’s possible. There are many different sites that will offer you the chance to play for free – including in our list of casinos on this page – and it’s a great option for novices too, who may want to learn about the game before staking cash.

In order to do this, in most cases you will simply have to:

  • Choose your favourite casino, taking into account the range of games.
  • Register your details and create an account.
  • Get playing, you will not have to make a deposit in order to play blackjack for free.

How to Play Blackjack on Mobile

The way we play games has changed considerably in recent years, with mobile gaming transforming the casino industry. The demand of players to be able to access their favourite games, like blackjack, on the move means that providers are optimising everything to the small screen. 

Obviously, the benefits of that are clear to see. It means you can play blackjack wherever and whenever you want, and it means the fun of the game is only ever a few clicks away. Furthermore, the quality of the game isn’t sacrificed on your mobile, with the graphics and gameplay faultless, ensuring you will enjoy what’s on offer. 

In terms of playing blackjack on your mobile, some casinos will have dedicated apps, although you can still access games through your browser. Either way, it’s extremely straightforward to play a game of blackjack on the move.

Blackjack Rules in Short

As touched upon, another part of the attraction of blackjack is that it’s so simple to play. Whilst different variations will have specific differences, generally, it’s a game that players will pick up in no time. 

You vs the dealer

Firstly, it’s just you against the dealer, where you will be given two cards initially and the aim of the game is straightforward: get 21, or as close to it as possible, and closer to it than the dealer. If you do that, you’ll win. 

In-play decisions

In an ideal world, you’d get an ace, which can be valued as one or 11, and a ten-card, whether that’s a number card or a face card. Then, you have blackjack. 

Unfortunately, it doesn’t always work like that, and when you don’t get the cards you want, you will have to make some big calls. You can stand if you want, which means you are happy with your number and feel it will beat the dealer. 

If not, you hit, meaning you get another card, but remember, you can’t exceed 21 or you’re bust. You can hit as many times as you want if you don’t go over 21. 

Furthermore, you can double down, which will see you increase your bet size for one more card, or split, if you receive two of the same cards, opening yourself up to two bets. If you decide to split or double down, the rules of the game don’t change, it’s still about getting closer to 21 than the dealer. 

Once you’ve settled on your number, the dealer will turn their cards over, play out if needs be, and the winner will be determined. It’s a quick game, although it does require both skill and luck.

Blackjack Terminology

Perhaps the only confusing aspect of blackjack is the words that a novice player will come across. If you don’t know what they mean it can be quite daunting, so here we will explain exactly what these blackjack terms are all about.

As well as being the name of the game, it’s the best possible hand, when you get an ace and a card valued at ten.
This is when your cards exceed 21 and you’re out of the game.
After seeing your initial hand, you can choose to double your bet, increasing the risk but also the potential reward, in return for one card only.
This is when you ask for an additional card.
The card that the dealer has that is face down. The one you can’t see until the game is played out.
If the dealer’s upcard is an ace, you can choose to take insurance. It’s an additional wager up to half the value of your stake, and you will be paid at 2:1 if the dealer has blackjack. If they don’t, you lose that side bet, and the game will carry on regardless.
If you and the dealer have the same values when the cards are revealed, it’s a tie. That’s known as a push and usually means your stake is returned.
If you have two cards that are the same value, you can choose to split. You will effectively have another bet and play with two hands for that game.
When you are happy with your cards, you don’t want another so you stand.

Blackjack Strategy

As blackjack is not just a game of pure luck, there are strategies that players will adopt to help them along the way. Of course, as we’ve stressed, nothing will ever guarantee you success when you are playing this game, as you don’t know which card will be turned over, which is what makes it great.  However, there are certain tips and strategies that you should always follow. 

  • Firstly, you should always split 8s and Aces. The latter is obvious because there are more 10 cards than any other in the deck, so if you can match that up with an ace, you will have 21. Whilst splitting 8s doesn’t provide you with the instant win, it could give you a high number. 
  • Elsewhere, you should double down on a hard 11, as the next card could get you the magic number. Meanwhile, players are advised to never split 5s or 10s.
  • There are plenty of ways for players to read up on the best blackjack tips and strategies, so it’s always possible to find out different ways you should be playing. It’s important to remember that no strategy is going to guarantee success, but because it’s a game that requires decision making, there are approaches you can take to playing that can help.

Blackjack Payouts

Now, to the question you will have all been asking – how much can I win from blackjack?

Sticking to the proof that blackjack is a relatively simple game to play, the pay-outs follow suit as it’s easy to understand. Generally, you will receive a return of 3:2 if you get a natural blackjack, which is an ace and a ten, from your first two cards. 

If the game plays out and you beat the dealer without a natural blackjack, the pay-out is 1:1, which means you double your money. The number that will be doubled will be the initial stake that you put down before the game starts. So, if you put down $10, you would get $20 back. If you bet $50 initially, you would receive $100, and so on. 

Different variations of the game can mean the pay-outs differ, so it’s important to check that you are playing in a game that will give you a suitable return – a paytable will always be provided.

FAQs

This page has looked at many of the key elements of blackjack that will help with your understanding and make your next visit to the table a special one. However, if you have any burning questions remaining then it is likely that they have been answered below

Frequently Asked Questions

Yes, of course it can. Some feel that because you are up against the dealer, therefore the house, you will lose. Of course, that’s not the case. You can lose, but all casinos are registered and licensed, so when you play on these regulated sites there’s nothing to worry about.

It’s a bit of both. You undoubtedly need the luck of the cards to help you get a win, but your decision-making will also play a part too. Did you hit at the right time? Did you double down when you shouldn’t? Players must make some big calls that will help determine the outcome of the game.

Understand the rules and apply certain strategies. Your decisions will play a part in whether you win or not. So, make sure you know when you should double down or when you should split. There’s no guarantee of success, but it will increase your chances if you do those things correctly.

Counting cards is when you keep a tally of the cards that have been dealt, meaning you have an increased chance of knowing what’s next, helping you to win. It’s extremely hard to master and it’s something that wouldn’t go down well at the casino!

Yes, they are. There are various names for blackjack, and some will call it 21. We’ve given you a rundown of the different variations, but they all generally follow the same way of playing.

Not if you are playing at the right casinos. At Slotsia we only recommend fully regulated and licensed casinos, and that should give you peace of mind whichever brand you choose.
