There are several big benefits to putting your trust in our expert team, and we’ll go over just a few of the most important ones.
Our dedicated and experienced team has developed a foolproof testing method for reviewing and ranking sites. Seven criteria, all weighed by importance, help us make the final verdict. The main one is looking at the proper casino licences and security, so you can rest assured that every platform we mention is legitimate.
Instead of running around from site to site to sniff out good deals – a few websites at a time – you can just hop onto Gamblizard and have instant access to 50+ blackjack offers. You won’t be able to find some on any other site, not even the casino brand’s itself. That’s because we always look for respectable casinos and try to negotiate special deals for our community.
With Gamblizard, you get only the latest deals as they come out, so you never have to worry about missing out or getting stuck with an expired promotion. We also cover the biggest casinos around, provide top lists, and give you all the facts – no flamboyant claims.
Do you know how to tell a good online blackjack promotion from a mediocre one or even a scam? It’s incredibly important if you want to stay safe online and get a chance to actually win something. Here are a few things to keep an eye on.
First of all, you need to read the Terms and Conditions carefully to make sure the bonus offer extends to blackjack.
It’s tempting to claim and activate the first promo you see that says it’s available ‘on table games’ when looking for blackjack bonuses, since they are not the most popular player choice, compared to, say, slots. This is precisely when you need to pause for a second and ask yourself, ‘Does it feature the title I want to play from the provider I like?

Each blackjack offer is a bit different, and we’ll be covering the types of bonuses later, but there will usually be an amount you have to wager before you can withdraw your bonus winnings. It can be anywhere from 30x to 65x the bonus amount.
Here’s an example. For 100% deposit match sign up offers with a 35x requirement, if you deposit £100, you get another £100, but you have to gamble £3,500 with just the bonus money before you can get the payout, which also usually has a max upper limit.
If the bonus expires and you don’t get to the set number, you will be left with only your deposited sum and whatever winnings you’ve made with that.
Wagering requirements are one of the most important conditions to consider when choosing a promotion, as they have the biggest impact on the real-world value of your rewards. Bonuses that have low wagering requirements are much easier to convert to real money, which means on average you’ll keep a greater percentage of your rewards.
By finding promotions with wagering requirements of 20x or lower, you can potentially double the expected value of your bonus.

You also need to understand how much each bet contributes to meeting the wagering requirements. It’s typically 100% for slots but 10% for blackjack, although in some casinos it may be as low as 5%. That means your £10 bets will only count as £1 towards the total sum you have to meet.
If we get back to the previous example, you’d have to bet £35,000 playing blackjack to clear the £3,500 requirement.
Some blackjack offers will work more in your favour than others. While there is some overlap with the kind of bonuses available for slots, having a cashback bonus on top of additional funds is perfect for table games like blackjack, as it lets you recoup some of your losses throughout the day or week.
Ok, so you can now tell when you’ve come across a decent blackjack bonus, but there’s a couple of types you should know about.
Players across Great Britain and Northern Ireland have access to a wide range of blackjack casino bonuses, but the differences between them are not always obvious at first glance. Some offers are designed for new players, others for regulars or high-stakes play, and each comes with its own conditions.
To simplify the choice, we compare the three blackjack bonus types players encounter most often: deposit bonuses, no-deposit bonuses, and no-wagering bonuses. Together, they cover the main playing scenarios, from low-risk testing to playing without wagering restrictions.
Most blackjack bonuses players see at registration come packaged as part of a welcome offer, which can include one or more of the bonus types compared above. A blackjack sign up bonus usually comes in the form of a deposit match up to a defined maximum amount or a cashback offer, sometimes both.
As soon as you set up your account, you’ll find the extra funds available for play and a set of T&C you’ll have to follow.
As the name suggests, with this offer, the casino will give you additional bonus funds that match your initial deposit, usually capped at £100 with a 30x to 40x requirement – just bear in mind the 5–10% wagering contribution for blackjack that we’ve mentioned. It’s often combined with a cashback amount or free spins for slots.
A pretty rare type of blackjack promo that doesn’t come with any strings attached, i.e. you don’t have to reach any fixed amount using bonus funds, so you’re free to play how you like and cash out whenever you want. Don’t hold your breath for this one, but they do pop up occasionally.
This option is a tad more common than the previous one, though not nearly as the matched deposit option. It also comes with some limitations and fairly strict wagering requirements. First, the bonus value will frequently be only £5–10 and come with up to a 60x or 65x requirement, a lower max cashout cap of £50–100, and a contribution of 5%.
It’s not just the new players who can look forward to promos, as casinos often have a bonus available for regular players, which can come in several forms, depending on the casino.
A quite common option for both long-term and newer players is to give them something extra when they add more funds to their account after they’ve emptied it, or even as weekly or monthly blackjack promo codes. Of course, reload bonuses are under a time limit, with requirements in the 30x–40x range, and may ask for a higher deposit.
As we’ve mentioned, you’ll often find blackjack cashback combined with a match deposit deal. It’s usually set at either 5% or 10% of the net losses from your initial deposit, though some casinos even offer lifetime cashback after you sign up, capped at around £100 max.
Casinos like to reward those who play blackjack online relatively frequently and leave large deposits. High rollers get different kinds of preferential treatment, either through coupons and codes or unique sign up offers for larger deposit amounts. They also stand to gain the most from continuous cashback promotions.
Casinos will sometimes have special seasonal offers for holidays (Christmas, Halloween, and Easter being most common) and a blackjack coupon code for birthdays or other special occasions.

We’ve covered all the bonuses you’ll come across in the United Kingdom, so it’s time to take a look at what games are eligible for most of them.
Obviously, the main game you can play with these bonuses is blackjack, but you may be limited to certain variations. For instance, its live version that comes with a live blackjack bonus. That means you’ll be unable to use your bonus funds on other types of blackjack. The selection can vary from casino to casino, so as we like to stress, go over the terms and conditions thoroughly before playing.
We should also mention that the best live blackjack offers are often lumped together with free slot spins, or they come as part of the casino’s Wheel of Fortune during the sign-up phase. So you can also play some slot games if that is the case.
There are ample opportunities to find an online blackjack bonus and enough variation to keep things interesting. Just remember that they do come with stricter wagering requirements and that only 5% or 10% of each blackjack bet contributes towards the total required sum.
As always, the Gamblizard team would like to take this opportunity to remind you to gamble responsibly – don’t deposit more than you can afford to lose, take breaks, and if needed, use self-restriction tools or call a helpline.

Yes, each online casino will have a set upper limit for winnings using the bonus funds, though you’ll be able to continue playing to meet your wagering requirements. However, you can only get the payout for the maximum allowed amount, regardless of your total winnings.
You can often find bonus offers during holidays, but aside from that, there are also daily or weekly cashback promos, and reload bonuses may be available as a regular feature. It will depend on the platform, though, so be sure to check in from time to time.
No. Every site will only have a couple of specific offers available at any given time, all tailored to different scenarios or types of players. For instance, you can’t access a welcome bonus if you are a regular, and trying to open multiple accounts for the same person is considered cheating and will get you banned.
To claim a bonus, you have to go through a quick process on the casino site, and after completing it, the funds should be visible on your account immediately or after a short amount of time specified in the T&C.
The easiest way to opt out of a bonus is to just ignore it and not play with the extra funds, just betting from your deposit. There is a time limit on all these promotions, so it will be cancelled automatically if you don’t use it for a couple of days.
