How We Ranked the Best Blackjack Bonuses for You

Choosing the right blackjack bonuses involves looking at more than just the bonus amount. Crucially, you should always read the terms and conditions of any bonus offer, especially the wagering contributions of blackjack games.

The best bonuses offer a higher contribution percentage towards these requirements, making them more valuable for blackjack enthusiasts. The casino sign up bonus is not always the most important consideration.

Wagering requirements and games weighting are also important things to weigh up. That’s why the best blackjack bonuses always come with the greatest contribution percentage towards the wagering requirements.

By tracking this percentage along with a few other important factors, experienced players are able to pick the best offers. In the rest of this article, we’ll take you through some things to keep in mind while looking for the best blackjack offers and bonus offers at UK online casinos.


Bonus Terms and Wagering Requirements

These conditions can usually be found within the pages for bonus and promotional terms or alternatively they will be located within the site’s general FAQs and Terms and Conditions pages.

Read carefully all the information regarding the wagering requirements because it is essential for knowing how many times you need to wager your bonus money to turn your winnings into real money that you can withdraw.

For example, let’s say the wagering requirement is 40x. That means that if you deposit £20, you will have to bet a total of £800 before you can request a withdrawal of the bonus money and the winnings.

Make sure to also look out for the validity period of your bonus. The best blackjack bonuses last for 30 days or perhaps even more, but others have much smaller periods of a week. Check out our detailed casino bonus page to learn more about the specifics of the wagering requirements during the bonus duration.

The major drawback of a blackjack bonus is its lower level of contribution compared to other casino games. As blackjack has a small house edge, it generally will not count entirely towards bonus wagering. Operators will occassionally offer a no wagering bonus, and you can check out our dedicated page on the subject if you would like to learn more.


Contribution Percentages

To give a real example of the importance of blackjack game weightings, some operators offer 20% contribution of their blackjack games towards the wagering requirements. Let’s see what this means.

In this example, if you deposit £20, you will get another £20 in your account. To clear the playthrough requirement of 30x, you will have to place a total of £600 in wagers.

However, only 8% of the money you bet on blackjack games will count towards fulfilling this requirement – this means that if you play only blackjack, you will have to bet a total of £7,500, which is a bit too much.

By contrast, if the playthrough requirement is 40x for blackjack, you will need to wager £800. However, this type of table casino game offers a much more substantial 20% contribution. This means that a total of £4,000 bet on blackjack will be enough to clear the requirement.


Maximum Bonus Amounts

The maximum amount of what you get for free becomes the next factor that determines how appealing a blackjack offer is. Some British casinos feature one-off offers also known as 1st deposit bonuses and in this case, you get the complete amount at once.

Other casinos offer multi-staged bonuses where the maximum amount is usually spread within the first, second and third deposit. Note that we didn’t include the free spins in this comparison because they can only be played on slots.

Top 3 UK Online Blackjack Bonuses


Blackjack-specific Offers

Most casinos have special bonuses offered on a regular basis and some of the most attractive ones are blackjack offer. For instance, you could be reaping the benefits of extra bonus money by entering a special code upon depositing.

You could also claim cashback on live blackjack side bets during the weekends. A perfect match if you enjoy placing Perfect Pairs side bets on live casino games at the best live casino blackjack sites!

This is only an example of how certain online blackjack offers could make one online casino more attractive than another. In some ways, there are casinos with welcome bonuses that are not available for blackjack games but their regular promotions can be the sole reason for your absolutely pleasant gambling experience.

By the same token, there could be a £5 deposit casino with a bonus not championing blackjack at all. Sometimes, exactly the live blackjack games create the best conditions for unforgettable and profitable casino sessions. There’s no accounting for taste!


Options for Live Online Blackjack Fans

The ‘Side Bet Insurance’ is a typical offer that makes any casino a top choice among others. This is especially true if you love playing live blackjack games with side bets such as Perfect Pairs. This popular side bet pays out if your first two cards contain a pair.

The best blackjack tables are broadcasted by top live dealer game developers, each offering great graphics, sound effects, side bets, statistics, live chats, etc. The number of hosted live blackjack tables and their max bet limits is also a very important factor to consider the more, the better.

For instance, our recommended operators offer over 15 live blackjack variants broadcasted by top developers such as Playtech, with table limits of up to £5000. Many of their games also provide you with the option to place additional bets like ‘Bet Behind’, ‘21+3 Bet’ or ‘Perfect Pairs’.

Blackjack side bets offer a shot at bigger payouts. Although they do come with a bigger house edge. For something extra while enjoying those live tables, check out our ranking of the best bonus Playtech offers and grab a deal.

If these table limits sound to you like the perfect choice for a high roller casinos, imagine what the stakes could be with 20% cashback up to £100! You can find that ‘Side Bet Insurance’ at the top British gambling sites. Shortly put, playing at a casino with special blackjack offers for the live dealer lobby is always beneficial.


Betting Limits

Many casinos will limit the maximum bet you can place on blackjack games to prevent bonus abuse. Many of the best bonuses for online blackjack limit the max bet with bonus funds to 10% of the deposited amount or £5. Keep this in mind if you prefer to play multi-hand blackjack.

Additionally, pay attention to table limits when you play either RNG or live blackjack games. The lower betting limits mean more favourable conditions for low-stakes players. If you prefer high-roller tables, then tables with higher betting limits are the right choice for you.


Payment Methods

Last but not least, don’t forget to check out the Payments page at the casino you want to play. Complying with the accepted payment methods plays a major role for a quick and effortless deposit.

PayPal is the banking method of choice for most blackjack players and this is mostly due to the easy and instant transactions.

Another reason for this is because many online casino blackjack bonus offers are not valid if depositing via Skrill or Neteller. Therefore, it’s pretty much PayPal that’s left as a main e-Wallet option for making a transaction.

When it comes to withdrawing your winnings, you should also know in advance which are the accepted payment methods, the timeframes, and the applicable fees. Luckily, there are no withdrawal limits, regardless of the chosen method.

If it is possible to withdraw by using the same method as for depositing – good, but that’s not always the case. Some UK casinos approve withdrawals only via direct bank transfers.


Comparing and Choosing Blackjack Offers

The factors we’ve outlined above should be useful in helping you choose from our list of excellent operators and their welcome bonus packages. There are still further considerations you can keep in mind when making your decision. Examples include type, variations, the availability of Perfect Pairs and other side bets, and software providers.

Again, be sure to carefully check terms and conditions of the blackjack offers and bonus offers and make use of the high contribution percentage of the blackjack games the higher maximum bonus amount.

  • The bonus money can be wagered on a wide variety of blackjack games;
  • The best blackjack bonuses usually come in a pack with other benefits.

Here are the major Cons that you also need to know upon choosing your favourite UK casino to play blackjack:

  • Lower contribution of blackjack and other table games in comparison with video slots, to compensate for the small house edge. Slots typically offer a complete 100% contribution towards the wagering requirements and you can find further details in our specially dedicated ‘slot bonus’ page.
