Our Top 5 Online Blackjack Bonuses

We ranked blackjack bonus casinos in the UK by their welcome bonus offers, blackjack contribution percentages, and blackjack game availability, making it easy for you to pick from.

1. BetVictor - 100% Blackjack Contribution

I picked BetVictor as the best site because there you can start playing blackjack right away with a 100% contribution to playthrough.

Once I had wagered the deposit, I received a daily bonus for four days, including £5 in cash for live casino titles. But I should note that the winnings also carry a 10x wagering requirement, so I wasn't able to cash out right away.

• Bonus: 200%/£20 + 50 bonus spins
• Blackjack game recommendation: Easy Blackjack by Evolution Gaming

It's still an excellent choice for beginners, since you can start with as little as a £10 minimum deposit. You'll find all the eligible deposit options, bonus terms, and more on our BetVictor casino review. I loved this rare welcome promotion package because you get a 4-part bonus with good terms, such as no wagering for the bonus spins, and everything with a single deposit.

2. No Bonus Casino - 10% Daily Cashback From Blackjack

Second, I chose a unique bonus of daily cashback on No Bonus Casino because you get it from the losses of playing blackjack. It's completely wager-free, so no need to worry about the contribution percentages.

The cashback is activated every 24 hours, and after that, you can choose to withdraw or play more blackjack from top providers like Microgaming, Stakelogic, Relax Gaming, among others.

• Bonus: 10% cashback
• Blackjack game recommendation: One Blackjack by Pragmatic Play

As our No Bonus expert review notes, there are a few things to consider before signing up for this site, like the high minimum deposit of £25. It can be quite high for beginners and casual players, but other than that, this is a straightforward way to enjoy blackjack with a small safety net from cashback.

3. Parimatch - Wager On Blackjack and Enjoy Multi-Part Bonus

Parimatch has a similar multi-part offer to BetVictor, with blackjack contributing 100% to wagering. While BetVictor has a bigger bonus, £20, and more bonus spins, 50, I really liked this one, too. I got to start clearing the wagering requirements on high-quality blackjack games from the get-go.

• Bonus: 150%/£15 + 30 bonus spins
• Blackjack game recommendation: Parimatch Premium Blackjack

Checking the full review of Parimatch shows all details related to claiming the bonus, including which payment options are available, and more. It's not the best option on our list, but the fair win cap of £150 and availability on blackjack games make it the third-best option.

4. 21.co.uk - Live Casino Bonus With Low Wagering

21.co.uk is my fourth pick because it offers a £5 live casino bonus, low wagering of 1x(D), and you can grab it with just a minimum deposit of £10. It's a solid offer as you can wager the deposit on any live casino game available. However, live blackjack contributes only 20% towards fulfilling the playthrough terms. This is enough for fourth place on our list, as it takes five times the effort compared to BetVictor.

• Bonus: £5 live casino chips
• Blackjack game recommendation: Blackjack Unlimited by Ezugi

Bojoko's review of 21.co.uk also highlighted the player-friendliness of this offer: low deposit, minimal wagering, no wagering on winnings, and what's more, the bonus has no win caps. It's also a great deal for those who like trying out different games, since there are over 50 live blackjack titles and over 150 other live dealer options available on 21.co.uk.

5. Videoslots - Best Selection of Blackjack

Videoslots has the best game options for fans of blackjack, with over 500 video blackjack and live dealer titles. As a newly registering player, you can claim a welcome bonus and wager it on blackjack, but note that it contributes only 10%.

• Bonus: 100%/£50 + 11 bonus spins
• Blackjack game recommendation: Classic Blackjack Gold by Microgaming

Although the contribution rate of blackjack is low on the welcome offer, our Videoslots casino review highlights the excellence of this brand in every other aspect. It's still the largest bonus on our list, so you have a chance to try out many titles with this one.

Our Take on the Bonuses

How Our Experts Rate Blackjack Offers

Bojoko's experts rate these bonuses by testing the sites first-hand and assessing key aspects like how much playing blackjack contributes towards wagering the bonus, where to find the most games to play the bonuses, and what the actual value of the promotions is for players.

Read more on our criteria on the casino reviews UK page and find out what it takes to become a top-rated site.

Blackjack Contribution Rate

We appreciate blackjack bonuses from sites like BetVictor and Parimatch that allow a full 100% contribution towards wagering on blackjack games. However, contributions between 20% and 100% are rare. It's more common to see a low contribution of 10% for blackjack, but 100% for slot games, like on Videoslots. This is because slots are considered simpler, faster, and their RTPs are lower than those of blackjack, so the house edge is lower on blackjack.

We advise avoiding sites that have slot-focused bonuses since those don't usually allow wagering on blackjack. For example, there are top-quality casinos like BetMGM and Play Jango that have excluded blackjack games altogether from contributing towards wagering.

Wagering Requirements

Wager-free bonuses are superior to bonuses with wagering because they allow players to convert their winnings into cash straightaway. On top of no wagering bonuses, we consider low-wager options with 1x-9x wagering worth the effort. In contrast, bonuses with 10x wagering on both the deposit and the bonus are considered high in our books, but they can be compensated with 100% bonus contribution.

Let's break it down to an example of different wagering contributions, so you can see how much you have to bet to be able to clear wagering. For example, when you get a game contributing 100% for a £50 bonus, 1x wagering will cost you £50, but with 10x wagering, you have to place £500 in bets.

Game Selection & Live Blackjack Access

Another important factor to consider is which games you can play the bonus on. Here, I am most certain that the more options there are, the better. A blackjack selection of 500+ games, like at Videoslots, increases the chance of finding eligible titles that you want to play. We also love that Videoslots has so many variants, from Classic to European and even Multi-Hand options.

Some sites may only allow playing RNG titles with bonuses and exclude live casino titles. There are exceptions with live games, like BetVictor and Parimatch. There were also brands that almost made it to our top list, like The Vic's Slots and Live Casino Bonus, but unfortunately, the list of eligible games doesn't include any BJ titles.

Bonus Value vs. Practical Value

A bigger bonus is not always better if it comes with bad terms like over 10x wagering, low win caps, and fast expiry times. 21.co.uk is a prime example of great practical value, as it has 20% contribution on BJ, low wagering of 1x(D), no win caps, and zero wagering on potential winnings. On the other hand, Parimatch and BetVictor have higher wagering requirements of 10x(B), but playing blackjack contributes 100% towards wagering.

The practical value is why Videoslots is in fifth place, since it has a wagering of 10x(B), and playing BJ only contributes 10%, so it makes sense to try out the other sites with better value first.

Types of Blackjack Bonuses

Here, we break down bonus types, how they work and share our honest opinions on which give the best value for blackjack gamers.

How to Pick the Right Blackjack Bonus

Aspects like game contribution and wagering are important to consider. Putting in the effort to compare bonuses ensures you get the best value for every pound you put in.

Check Blackjack Contribution First

We always check first what the contribution percentage is for wagering on blackjack games. It will tell whether you can start playing blackjack titles as soon as you have claimed the offer, or if blackjack titles are excluded.

If I didn't spot the contribution rates right away, as a practical tip, I headed to the casino's T&Cs, did a word search with keywords like 'blackjack' or 'table games', which helped me to find the percentages.

Calculate Effective Wagering

Effective wagering can be calculated before claiming the bonus, and here's how it works: Bonus/Deposit × Wagering ÷ Contribution Rate = Total bets needed.

For example, 21.co.uk has a £5 bonus, a minimum deposit of £10, a wagering requirement of 1x for the deposit, and a blackjack contribution of 20%. Total bets needed is the result of £10 deposit x 1 ÷ 0.20 = £50. Here you can see that low wagering and low contribution are big factors, and reasons why we rank 21.co.uk above Videoslots despite the smaller bonus.

For Videoslots, the bonus is a 100% match-up offer, wagering is 10x for the bonus, and the contribution is 10%. So all in all, you'd have to play through £5,000 on blackjack games, which is a lot more than the other sites.

Understand Time Limits

Welcome offers usually have a certain window you can claim the bonus, and a separate time frame to wager the bonus. We think a good bonus will be available for a week after joining the site. Depending on the wagering requirements, casinos should allow between 1 day and a couple of weeks to complete the playthrough.

Read the Game Restrictions

Checking out game options for a bonus offer is crucial, as many sites may exclude live blackjack or individual blackjack titles. We think a great blackjack bonus can be played on all blackjack titles, like at Videoslots.

I have come across bonuses that have a bet limit, which may directly exclude some game options, like options with very low min stakes of £0.01 or bets above £5, for example.

Pros and Cons of Using Bonuses for Blackjack

After accruing plenty of experience playing blackjack at online casinos, here are our expert conclusions of the upsides and downsides of BJ bonuses:

How to Claim a Blackjack Bonus

1. Check bonus terms and conditions: See our reviews for contribution percentages, wagering, win caps, time restrictions, and max bets
2. Pick a site and register: Head to the casino via our green links, create your account, and verify your profile
3. Claim the bonus: Opt-in if necessary and place a deposit
4. Enjoy your blackjack bonus!

Casinos usually direct their customers towards slots for bonus wagering, so exclusive blackjack bonuses are uncommon. This can mean overcoming a couple more hurdles, such as finding eligible games for wagering. Due to blackjack's lower house edge, however, bonuses that allow 100% contribution from blackjack can offer an easier conversion route.
