21 Casino is a White Hat casino that’s been around since 2015.  The welcome offer speaks for itself!

About 21 Casino

21 Casino runs on the White Hat Gaming platform, which was set up in the early 2010s and has licenses from the UKGC, Malta, and Sweden’s regulator Spelinspektionen. The White Hat platform is well respected and was one of the first to be awarded a full UK Gambling Commission licence back in 2014 (yes! before a number of household names).

White Hat powers around 30 sites, including Slotnite, SpinYoo and Casimba, and grew rapidly in the late 2010s, striking a series of deals including a commercial partnership with the Kambi Group in 2018 which saw it expand into sports betting. Since 2020, it has also been providing gaming services to over 40 venues in the United States.

21 Casino is one of the earliest White Hat brands (it was launched in 2016), and it has many of the signature features of a White Hat site including a generous welcome bonus, slot RTPs set toward the higher end of the range, and a strong live casino section.

At the bottom of the home page you can find the site’s credentials, which include confirmation of its MGA and UKGC licenses. There are also links to six gambling support services, backed up by a comprehensive responsible gambling section. Our only criticism is that the information on this part of the site could be presented in a more user-friendly way rather than as a wall of text.

Getting Started at 21 Casino

21 Casino has the look of an old school online casino, with a very understated design showcasing the games against an almost plain black background with just a hint of gold. Apart from a crown motif and the fact that the welcome bonus is a quirky 121% deposit match, there isn’t much evidence of the theming throughout the site.

It may not be much to look at, but navigation between the various sections of the site feels more player friendly than at many sites. There are ten options across the top of the home page, including Top Games, New Games, Drops & Wins and you also have the ability to search by game provider, something which is often absent at online casinos these days.

The sign-up process is via a standard online form and only takes a couple of minutes; you don’t have to make a deposit to complete the registration process, which is good to see. Identity verification is required, although we would welcome more transparency about the KYC process on the site.

Slots at 21 Casino

Another feature that stands out at 21 Casino, and that we’d like to see more of at online casinos in general, is the information that is provided about the available games through the game tile. By mousing over or touching the tile you can see details about the number of reels the game has, how many win lines and the volatility, all of which is really helpful to players when browsing the game library.

Other useful tools include the ‘related tags’ and ‘related features’ that help you to track down similar games. Each game has these attached, and they’re very handy. For instance, What The Fox Megaways has the tags, ‘fox’ and ‘money’ and ‘bonus wheel’, ‘cascading wins’ and ‘spins feature multiplier’ as the searchable features.

The game library is the standard White Hat gaming platform, with a little over 1,000 carefully curated games, drawn mainly from the high-profile developers with which White Hat has partnerships, including Aristocrat, NetEnt, IGT, Evolution and WMS.

Between 2018 and 2020, the operator struck deals with Red Tiger, Push Gaming and Green Tube, so features games such as Rainbow Jackpots and Book of Ra , along with selection of titles from some of the operator’s smaller-scale partners including Route 777 and Ivanhoe from ELK Studios and Fruitopia from Tom Horn Gaming.

21 Casino goes big on jackpot slots, which number 194, almost 20% of the total game catalogue. The jackpot section includes many of the best in the genre including Rhino Rampage and Divine Fortune along with five variants of Mega Moolah and several Jackpot King games.

Table game fans can play around 40 titles, and there’s some variety to be found here, despite the relatively small collection. Games like Extreme Wildfire Roulette and Monopoly Travel World Tour are welcome additions. If you’re looking for more obscure table games, however, you’ll be out of luck. There’s only one keno title, two Sic Bo options and a couple of craps games. Even casino favourite Baccarat is underrepresented with just six titles.

The live casino section at 21 Casino is provided mainly by Evolution, Pragmatic Play, and Authentic Gaming and it features a small range of roulette, blackjack and game show variants, including Vegas Ball Bonanza and Cash or Crash. There is also a section entitled Other Games, which is where you’ll find the slingo, plinko and scratchcards.

Other Things To Consider

If 21 Casino has a clear weak area, it’s the promotions page. If you click on this menu option you’ll see details of the welcome bonus offer and nothing else. There is no evidence of regular reload bonuses, free spins promotions, loyalty schemes or any of the other promotions that you expect to see from a modern casino site.

Although this is one of the older sites in the UK market, it doesn’t operate on the old model of downloadable apps for each operating system. Mobile players can access the games and features through their mobile browser, which appears to run smoothly on most devices.

We came across reviews suggesting there were issues with accessing live casino games through the mobile browser, but we didn’t see any evidence of this, so perhaps it’s a problem that has been ironed out after customer complaints.

The site has a refreshingly accessible customer support service. Clicking on the contact option opens up a link to the help centre and an email address, as well as the live chat button. With some sites it can feel as though players are being deterred from getting in touch with customer service, and the 21 Casino model is one that a lot of operators should consider following.

Final Thoughts

If you’re looking for a flashy modern casino site full of gamification features and regularly updated promotions, 21 Casino is going to be a disappointment. The site doesn’t look at all flashy and does not stand out from the competition. It is also very much focused on slots and casino gaming, which is pretty old fashioned these days; most online casinos in the 2020s also offer bingo, sports betting, esports or even all three.

If you don’t mind that, you may appreciate the generous welcome offer with its relatively low wagering requirement and enjoy the game selection, which while it is not the biggest in the industry, covers all the bases and has a navigation system that is second to none. In fact, we haven’t found many sites that can rival 21 Casino for the range of features that make it easy to find the game you’re looking for. Factor in the good customer support, choice of payment options and the good reputation of the platform, and you’ve got an underrated casino site that scores highly where it counts.
