21 Casino Review [updated for 2024]


21 Casino Review

21’s a number gamblers love, so this 2015-created casino site from seasoned industry operators White Hat Gaming Ltd has a head start into the affection of players.

21 means blackjack to most of us – the hand that pays the best in the world’s favourite casino card game. And you can enjoy the hell out of blackjack at 21 Casino, including lots of live versions. You can do a lot more than that too at this nicely designed and slick looking site.

21 Casino has hundreds and hundreds of games, taking in slots and casino simulators as well as those live casino tables.

White Hat Gaming are based in Malta, along with the majority of Europe’s online casino industry. The company operates as a turnkey and white label provider. Turnkey is a business term that means a business is sold ready to go: turn the key in the lock and open up! And turnkey casinos are fully-fledged casino sites that are developed and set-up by people like White Hat gaming and then sold for others to run. The White Label model is very similar. A company with the facilities – hosting, licensing, customer support – runs sites as franchises, with the end-operators putting their own branding on the site.

Both models are really popular in the industry. They have pros and cons for you, the customer, which we’ll cover in this review, but you can trust White Hat to live up to their name and provide a safe and legal service.

And beyond that, should you start counting to 21 at this site?

Let’s dive in and see.

21 Casino Pros & Cons

Casino sites are complex operations and judging them takes time, but let’s have a quick look at the headlines from 21 Casino.


A Licensed and Legal Site

Let’s get the most important thing out of the way first. White Hat are licensed to provide a number of remote gambling services to UK consumers by the UK Gambling Commission. In fact, they’re also licensed by the authorities in Malta.

Both these authorities are considered good quality regulators. To more important for you, though, is the UK Gambling Commission licence.

We’ve checked it, and it’s up to date, and there are no sanctions against the company, who are confirmed as the operators of a number of sites in their own right – including 21 Prive, Diamond 7 Casino, and Gday Casino – and of white label site. The white labels include this one, 666 Casino, Miami Dice, Reel Island and many more.

The Malta licence is for the company.

Together, along with industry body memberships and the good quality safe gambling links on the front of the site it’s obvious that 21 Casino is a legitimate site that you can use safely.

A Big Selection of Games

We count 112 game providers at 21 Casino. From 1×2 Gaming to Yoloplay that’s a comprehensive alphabet of the industry, from big names like Red Tiger to smaller developers like Slide City.

These titles – which we’ll cover in full later – take in slots, jackpot slots, table games, live casino games, and other titles like virtual sports and scratch cards too.

The games are well arranged and easy to find – that providers list is there on the site to help you find your favourite makes – with a good search function and good site design.

Live, live, live!

Live casinos is what everyone seems to want from their casino sites these days.

We found a relatively small but good selection of live games from the best providers at 21 Casino.

The giants of the scene are NetEnt and Evolution Gaming, and 21 Casino has their titles, including all your casino favourites, like roulette and blackjack, but there are also game show games, virtual sports studios and more to check out.


Back to the technical stuff again, but 21 Casino do a great job on telling its customers what’s going on with the site. As it’s our job to find out about a casino site we love sites that make it easy to do so.

So we love the good quality and easy-to-find information at 21 Casino and you should too, because things like privacy policies, and how to contact the help team are important and you need to know how to find them too.


Nobody’s perfect, as they say! So here are some down sides at 21 Casino


Are you bored of sites that look the same and offer very similar levels of service and performance? 21 Casino does a lot of things very well indeed, but like all white label casino sites it comes from a standardized template. This doesn’t affect quality in a lot of ways, but if you want to see something different or if novelty is a big thing to you then you may find things a little stale here.


PayPal is the biggest and most trusted online payment system in the world, and unfortunately it’s not an option at 21 Casino.

There are lots of other great options, but PayPal – together with crypto or Bitcoin options in the near future – payments are a really great option to see at a casino site, but alas you will not see it here, for now.

Where are the offers?

One big plus is that the welcome offer is straightforwardly good value in coming in with a higher percentage return. And the loyalty programme is super simple to understand and doesn’t look like it was designed by someone with a degree in complex astrophysics like some such schemes.

But where’s the rest of the glitz and glamour? Offers and bonuses have a downside but it’s nice to be offered a choice and 21 Casino doesn’t have much going on on the promotions page at the moment.

21 Casino Games and Software

21 Casino

The site is run on White Hat’s own software, with games from over 100 developers.

Let’s go through some of them.

21 Casino Slots

Slots are the bread and butter of the online casino industry, and as you’d expect they are the main part of the offering at 21 Casino.

They arrange their games in a number of ways to preview them, including by provider, including:

Table Games

Casino games come in two flavours. The games we’re listing here are called Table Games at 21 Casino. These games are computer simulations of games, not live games, which we’ll cover later.

We found 40 games in total, taking in all the classics, and poker.


Everyone loves roulette – including casinos, who can make a nice profit from this classic game! At 21 Casino we found nine variants, including:

European Roulette, Roulette Nouveau, Double Ball Roulette, 3D European Roulette, Roulette Advance, European Roulette Gold Series, European Roulette, French Roulette, and American Roulette.


Blackjack has a few variants, and there are lots of branded titles and rule options that include different side bets and different player options. Please study the game – or play on demo mode – before you start to throw your chips on the table.

At 21 Casino we found:

Blackjack, Blackjack Pro Monte Carlo Pro MultiHand, Blackjack Pro Monte Carlo Single Hand, Blackjack 21 + 3, Blackjack Lucky Ladies, Blackjack Lucky Lucky, Buster Blackjack, 3D Blackjack, Atlantic City Blackjack Gold Series, 6 to 1 Blackjack, European Blackjack, and Blackjack Perfect Pairs.


Poker can be played as a live game, as a simulator, and in a slot variant called video poker. Here we’re looking at table game simulators, which deliver dealer games.

At 21 Casino you can play:

Casino Hold’em, Texas Hold’em, 3 hand, Casino Hold’em, All Aces, Poker, Mississippi Stud, Pai Gow Poker, DJ Wild Stud Poker, Jacks or Better, Let it Ride, and Texas Hedge ‘Em.

Other table games at 21 Casino

Also available at 21 Casino are baccarat, dice games, and Casino War.

Bonuses at 21 Casino

Every site will offer you a number of promotions. Typically these will include a welcome offer – always the biggest and most eye-catching – and a loyalty programme.

Welcome Bonus at 21 Casino

Talking of eye-catching, the welcome bonus here is styled around the name of the site, with an unusual 121% bonus.

Straight from the off that gives us a 21% headstart on the standard cash-match format – it also complicates the maths!

The maximum bonus is £300.

Sounds great! So let’s look at the restrictions.

The minimum deposit is £10.

There is a 35-times wagering requirement on this bonus. A wagering requirement is a sum of your own money that you must play with in order to release funds from the offer. In this case, the wagering requirement must be paid off with bonus funds – cash funds do not apply. At least that’s what the site tells us.

Games are weighted in relation to this wagering requirement, which means that not all wagering is equal. There is a list of the titles affected and their values at the site.

There is a maximum bet of £5 applied to all bonus funds.

There are lots of other restrictions on bonuses too. They include strict rules on play that are designed to stop people “taking advantage of” the bonus, but, which to you might just feel like common sense tactical or strategic decision making.

The figures mean that a bonus worth £100 needs a minimum of £3,500 of casino play before it can be withdrawn.

The terms at 21 Casino are fairly typical for the industry, and, in fact, we’ve seen much worse.

We are not big fans of the bonus scene in the UK casino market. And we don’t think that regulators are either. The purpose of a bonus is obvious – it is to get the player in through the door, but also to encourage them to deposit and play with a large amount of their own money, often in a very short time. Keep this in mind. The best way to use a bonus is as a free guide to the site. Forget about the money, and consider forfeiting it if you like the site and it’s worth your while to stick around in any case.

Other Promotions

Promotions come and go and are often tied to calendar events, game releases, and current events. They change regularly, and you should check in as you sign up to see what’s on offer and if you like it.


We found no tournament play at 21 Casino.

Daily Promotions

There were no daily promotions at 21 Casino when we visited.

21 Casino Loyalty Schemes and VIP

No modern casino doesn’t have a loyalty scheme. Most are triggered automatically as soon as you join the site. It’s another feature that regulators are believed not to be keen on, and – as their concerns are related to the extent to which loyalty schemes, and particularly VIP schemes could encourage dangerous gambling behaviours, it is something that you need to be aware of too.

21 Casino is no exception, and its loyalty scheme called, Royal Loyalty, is very simple and easy to understand.

Every time you bet you earn loyalty points. Once you have earned over 200 points you can start to redeem the points as bonus cash. The points are redeemed to the player at the rate of 200 points to £1, with a maximum daily limit of 10,000, worth £50.

Points are awarded on a differential scale, with £10 being worth 2 points on slots and scratch cards, 1 point on bingo, and video poker, and 0.5 points on blackjack, and 0.25 points on roulette games.

The 35-times wagering requirement applies to withdrawals of bonus funds, with the £5 maximum bet on bonus funds – though these funds do count towards your loyalty balance, and there is no maximum figure on the amount you can win from bonus fund bets.

You only get 30 days to use bonus funds.

Again, these terms are pretty good for the industry, but you need to be aware that the whole structure of the offer is designed to encourage you to play more and to spend more, and if that’s not a good thing for you then you need to make the right decisions for you – not the casino site!

We like that this offer is very simple, most loyalty programmes have multiple layers and bonus items – here it’s just cash for points and super-easy to understand.

21 Casino Live

Live casinos are taking players back to the future. The very latest in web tech is used to deliver what you could have got by walking into a casino in the past. Games are played at a remote location and a weblink handles the interface between the player and the dealer or croupier.

Be aware that live games are often slightly more expensive to play, because of the cost of staffing all those tables, and you can very rarely try out the games for free – so make sure you know the rules properly.

Also be aware of the use of sexualised imagery and attractive staff to encourage you to play and spend more. Make decisions that are good for your health and your bank balance, not based on a perceived relationship with casino staff. Always treat casino staff with the utmost respect too.

At 21 Casino we found a quite small but high quality selection of games.

Not all casino tables are available to all players at all times, so you need to be aware of that.

We found:

Live Roulette at 21 Casino including Evolution Gaming Roulette Live, NetEnt Classic Roulette, and Auto Roulette.

Live Blackjack at 21 Casino included Evolution Gaming Blackjack, and NetEnt Blackjack Live.

You can also play Baccarat Live, various poker titles (including Texas Hold’Em, Three Card Poker, and Caribbean Stud Poker.

Other titles included Mega Ball, Deal of no Deal, Dream Catcher, Dragon Tiger, Sic Bo, and Football Studio.

21 Mobile Casino and App

Mobile access provides access to the majority of games and services on the site via a mobile adapted website. There is no app to download.


Banking makes the casino world go around.

At 21 Casino there’s a good selection of the latest payment methods with which to open your account, fund your play, and receive winnings.

They include:

  • Visa debit cards,
  • MasterCard debit cards,
  • Maestro debit cards,
  • Trustly,
  • Paysafecard,
  • Skrill,
  • Neteller,
  • PayPal,
  • Bank Wire.

Customer Support

Customer service is just about the most important thing at a casino site – beyond the legality. Hopefully these are services that you’ll never need to use, but every player should make sure that they know what customer support is available to them and how they can access it.

At 21 Casino you can use a live chat button to open a chat window that is open 24/7. Or you can email support@21casino.com.

The Final Verdict

Casino 21 delivers a lot of good things without exactly setting the world on fire. In casino terms, it is a great mid-table premier league club but it’s not one of the big guys who you should expect to see in the Champions League every year.

The things it does deliver include:

Nice design that make a site that’s easy to use and a pleasure to look at.

Lots and lots of good games, that are well arranged and easy to find.

It also scores pretty well for the quality of information that is available around the site.

It’s great to see a simple, straightforward loyalty scheme that isn’t weighed down with bells and whistles and stupid jargon!

And the welcome offer is pretty good, though we’re not so sure about the clause that says only bonus funds count towards paying off a wagering requirement.

Everything at 21 Casino will give you a really good casino experience.

Our only real concern – beyond that strange welcome offer – is that what 21 Casino does is almost exactly the same as what a whole lot of other sites do. And because it is a white label site that means that in some cases it is exactly the same service and offer.

How should you rate this site? The best thing for players faced with a lot of quite similar sites is to shop around, but to be aware of the dangers of chasing bonuses. There’s enough at 21 Casino to make it a perfectly good site for the long-term, especially for new players, but if you already have a good favourite site then you might not want to switch. Take a look and judge for yourself.
