Free Bets Bonuses for Online Blackjack

All the best online blackjack sites will offer bonuses and even free bets to new players. Most of these bonuses are given when you deposit funds into your casino account and then you get a percentage match up to a certain amount. Many casino bonuses also include free spins. It is important to note that not all casino bonuses are suitable for playing blackjack and this is because the game has such a low house edge making it one of the excluded options when playing with bonuses. When bonuses are available, you may find that the wagering contributions are quite small. Whether you are a new player or an exciting player at platforms in the UK, you will find bonuses to use, and listed below are the most common options.

Blackjack Sign Up Bonus

The casino signup bonus is reserved for new players who open an account. In most cases, this is a percentage match on your first deposit and an example would be a 100% match offer up to £100 which means if you deposit £100 you'll receive £100 in free bets, essentially doubling your bankroll. Welcome bonuses are another popular online casino bonus for new players in 2024 and this is where you receive a percentage match on your first number of deposits resulting in a high bonus amount and these packages often come with free spins.

Are there No Deposit Bonuses For Online Blackjack Players?

The most sought-after bonus at the best blackjack sites UK offers is the no deposit bonus and while these may be hard to find, there are some sites that still offer them. They are for new players and are relatively small. You might get £5 in free chips bonuses to play casino table games and the great thing is that you can win real money from top no deposit bonuses. It's a great way to get started at a new bonus casino and there is no risk involved. You might also come across excellent free spins promotions where you can use the winnings to enjoy the classic game of 21. Just make sure to evaluate the terms and conditions before claiming such an offer in 2024.

First Deposit Bonus

The first deposit bonus is a percentage match given when you first fund your new best blackjack site account. A typical example of this is a 100% match bonus up to £100 although there are higher bonus amounts available too. Be sure to check our top 10 first deposit bonus deals for 2024 for more information.

Cashback Rewards

Cashback rewards are for existing casino players and at the best online blackjack sites they are often reserved for high roller players who like to spend big. The casino rewards them by offering cashback on their losses. As a high roller reward, cashback bonuses usually don't come with wagering requirements.

Bonus Terms - How To Win & Keep Real Money

Because blackjack is a game that has a very high RTP, it can often be excluded from casino bonuses. When you do find a bonus that allow you to play for free, you need to check the terms and conditions especially if you want to win real money. The first thing to look at is the wagering requirement contributions. Having has such a low house edge, you'll likely find that betting on it rarely counts 100% towards the wagering requirement set for the bonus. The typical contribution percentage is 10% but it can be lower and this means it will take you longer to clear the playthrough and cashout your winnings. Another area to look at is the maximum cashout amount. Many blackjack sites in the UK have a cap on winnings derived from playing with a bonus and this could be around £100.

The Top 10 Online Blackjack Best Odds To Win

If you want to best odds of winning when playing UK online blackjack games, our top 10 list below can help. The table lists the RTP percentages making it easier for you to pick the one that will increase your chances of winning.

Game RTP Software Blackjack Switch 99.92% Playtech Vegas Single Deck Blackjack 99.69% Microgaming Blackjack Surrender 99.66% Playtech Atlantic City Blackjack Gold 99.65% Microgaming Vegas Strip Blackjack 99.65% Microgaming Blackjack Classic 99.65% NetEnt Pontoon 99.64% Playtech Multiplayer Blackjack Surrender 99.62% Playtech Vegas Downtown Blackjack 99.62% Microgaming Player's Suite Blackjack 99.60% IGT

Blackjack House Edge and RTP Explained

The house edge is the casinos winning advantage and while best online blackjack sites in the UK offer plenty of fun and excitement, the online casino still want to make money and they do this by having a house edge or a built-in advantage. It is essentially the percentage of bets kept as profit by the casino online.

The RTP stands for Return to Player, and this is a percentage of the total bets that is returned to a player as winnings. The RTP percentage will vary depending on the variant you choose to play. Single deck titles have a high RTP and lower house edge whereas multi-hand ones have a lower RTP and higher house edge. The percentages will vary from one to another casino, so it is always advisable to look at this before deciding which variation to try. The house edge should be visible to players and all titles should display their RTP.

Live Dealer Blackjack Vs Casino Computer RNG

While both live dealer and RNG options are exciting there is a difference between UK regular online and the best live blackjack sites. Online gaming blackjack is a computerised version that uses Random Number Generator (RNG) software. When you choose your title, all you have to do is place your bets and the entire process is then automated. Live dealer, on the other hand, is a more immersive experience that allows for interaction. Instead of playing against a computer-generated dealer, you actually get to enjoy with a real live dealer and everything is streamed onto your computer from a live studio or casino. The dealer deals the cards, and they will be shown on your screen. You then place your bets in the same way as you normally would, and the dealer is notified. So live blackjack is really like playing at a brick-and-mortar casino without having to leave your home.

Both versions are available at the best blackjack casino sites but if you are looking for more engagement and interaction, the live dealer experience is the best choice.

You can play on mobile and desktop and there are even apps you can add to your iOS or Android smartphone. Simulators are like the free play for fun option you can choose at many of the best blackjack casinos in 2024. With the freeplay mode, you can learn the basics for free and try out all the different variants before you choose to use real money.

The big difference between free simulators and real money online games is of course the ability to win real cash. With simulators or fun play titles you are using virtual credits and a deposit at the casino is not required. In order to use real money you must make a deposit or use a no deposit bonus which will allow you to try and win real money.

Printable Blackjack Strategy Chart

The basic strategy is recommended for anyone playing for real money and it essentially tells you what to do based on the cards you receive and the dealer's up card. Below is a printable strategy chart.

Most Popular Betting Systems

There are a number of betting systems you can use when playing at online black jack casinos and these include:

basic blackjack rules

Basic Guide For Beginners

Now that we've explained and recommended the greatest platforms, let's take a look at how to actually play the game and what makes it so popular. There are fair payouts and the rules are easy to learn. We recommend starting out by playing at trusted minimum deposit casinos where you can deposit £5, £3, or even £1. This is ideal for beginners who want to play on a budget. The following sections will also help you learn more about the game.

How to Play Blackjack

Often called 21, the aim is to get a card hand value closest to 21 to win. If you score above this you go bust or lose. You also have to beat the dealer's hand. In all cases, you place your bets, then the cards are dealt, and you have to decide whether to hit or stand. There are other decisions such as split or double down as well. The dealer will then take his turn and reveal his facedown card. You will win if you have a higher hand value than the dealer. You lose if it is lower. Before you decide to use real money at any of our top 10 UK online black jack casinos there are some rules that you will want to follow and understand.

Rules of the Game

Vasinos have become increasingly popular and with so many variations to play there's so much fun to be hand. Before you play for real money it is important to understand the rules. The main rules are simple and we've listed them below.

The rules are easy enough to understand but as there are hundreds of variations available, each will have its own specific house rules and these will affect the RTP and your odds of winning.

Blackjack Odds and Payouts

The game has the highest RTP and it usually over 98%. This means your odds of winning are better. The house edge tends to vary considerably depending on the type you are playing, and it can be between 0.5% and 8%. Your odds of winning increase significantly when you choose titles that have a 3:2 blackjack payout.

A 3:2 payout means that if you bet £10 and get a blackjack you win £15. If you play a variant that has a 6:5 payout you would only win £12 for the same bet. This means that if you play 6:5 versions your probability of winning is going to be lower.

Odds can also be affected by side bets, so it is important to look at these. Side bets will usually have a higher house edge. The house will always have an advantage but this is the game with the lowest house edge. The difference in the rules can affect the house edge and it is important to choose options with the highest RTP when using real money. You'll find the highest RTP titles at our recommended casino sites.

Popularity of Online Blackjack at UK Casino Sites in 2024

Black Jack is the second more popular game after slots at UK online casinos. It seems Brits spend hours playing this card game and with so many variants and even live dealer titles it's easy to see why. Most people believe the standard variant is the most popular choice but it seems Brits actually prefer to play Atlantic City, Multi-Hand, Spanish 21, and even Vegas Strip all of which can be found at our highest-ranked casinos.

Side Bets

Side bets are additional bets that you can make during your gameplay. These bets do have a lower RTP than the main game so if you use them, be aware that they will make it more difficult to win money from them. The side bets do add extra excitement and of course, if you win they offer big returns.


This is a type of side bet that pays out if the dealer gets a blackjack with their first two cards. While you still lose your hand, you also get some of your wagers back.

Bet Behind

Bet behind lets you bet on another person's hand instead of your own. You have no control over the decisions that are made but you do win if they win.

Pair Bets

There are three different pair bets depending on the different types of pairs you can get on your first couple of cards. These bets are placed before the round starts. With Perfect Pairs you bet on getting the two same cards of the same suit and this has odds of 30/1. Coloured Pairs is betting on getting two cards of the same colour and value, but a different suit and it has odds of 15/1. The Mixed Pairs bet is betting on getting a pair of different colours and this has odds of 7/1.


This is a side bet based on your first two cards and the dealer's face-up card making a strong poker hand. The better the hand created the more you win. This side bet was inspired by Poker and a suited three-of-a-kind is the best and has odds of 100/1. Other bets include betting on a Flush, a Straight, a three of a kind, and a straight flush. The odds range from 5/1 up to 40/1.

Basic Strategy

When you play UK online black jack casino games a basic strategy takes the guess work out of what moves to make. It literally tells you what decision you should make based on the two cards you have been dealt and the dealer's face-up card. There are strategy charts available for different variations but some of the basics never change and these include hitting on a hard 11 or less and standing on a hard 17 or higher.

When to Surrender

Surrendering allows you to pull out of the game and get a portion of your bet back. It is only available in certain types of games. It is worth using if the dealer has an ace or a 10 and you have a weak hand such as a hard 12 or 17 with no ace. These are situations where you are likely to lose so using the surrender option is a good idea.

When to Double Down

Doubling down is where you double your bet in exchange for one more card. You should only do this when you have better cards than the dealer's face up card and there is no possibility of you going bust with whatever other card you may receive. This strategy works well where you have a hard 9, 10, or 11, or a soft 16, 17, or 18.

When to Split Pairs

When you split pairs it gives you two chances of winning and also doubles your bet. It is recommended that you split aces so that you get two strong hands. The decision can often come down to what card the dealer is showing but general consensus says that you should avoid splitting 10s, 5s, and 4s. You should only split pairs when you want to create two strong hands.
