Website UX & Registration 9/10

Whilst many white label slot sites can appear rough and the edges, 21 Casino has a superior quality to it. The logo is refined with a crown motif and the black, grey and gold color scheme with smart font evoke the feel of a high-end casino. 21 have also taken the time to publish a ‘Why Us?’ statement outlining their background and commitment to fair and secure gaming. This is unusual for a small white label and another indicator of the integrity of the team behind it

Finding Important Information

Important information is easy to find. Links to promotional terms, legal information, complaints procedure, and responsible gambling are all clearly displayed on either the main menu or footer menu.  Another nice feature of the site is the Shield icon at the top of the screen on every page. Click it to reveal the Responsible Gambling page with links to set your limits or set up time outs. It’s all very clear and easily accessible.

Sign Up and First Deposit

The 21 Casino sign-up form and cashier are slick too. Registration through to completed deposit via Paypal took me just over 2 ½ minutes. It all takes place in a smart form that pops up in an overlay above the main site. It’s a four-step process and you’ll need to provide your email and mobile number as well as name and address for verification purposes.

It’s common practice now to make bonuses optional and 21 Casino have chosen to follow this trend. I like this as it allows you to avoid complex wagering and withdrawal restrictions. I chose to opt-in on this occasion for testing purposes.

My deposit of £10 was matched with a 121% bonus as advertised on the site and my balance updated to £10 cash and £12.10 bonus funds. Bonus Details linked from my account page show my remaining wagering requirements in both % and GBP (currently £423.50 – 35x £12.10).

Again, this is all clear and transparent and make tracking my wagering easy to do.

Online Slots 9/10

With the White Hat Gaming platform behind it, 21 Casino can boast an excellent games catalogue with just over 100 game providers supplying the content. Top names like NetEnt and Big Time Gaming sit alongside many smaller studios like Slot Factory, Shuffle Master and Red 7. Cult high variance studios like Nolimit City, Relax Gaming and Thunderkick are all present too. We checked for any glaring omissions and the only big providers not represented here are Quickspin, Novomatic and Yggdrasil.

In total there are over 2,500 slots to choose from.

Jackpot Slots

We reviewed the jackpots selection found via a Progressive Jackpots link in the game menu. There were games from the Mega Moolah series (Microgaming), Dream Drop Jackpots (Relax Gaming), Jackpot King games (Blueprint Gaming), Drops and Wins (Pragmatic Play) and Red Tiger’s Must Drop Jackpots. In total there were upwards of 150 to choose from.

New Slots

There is also a ‘New’ games tab which revealed a very up-to-date catalogue including slots that had only been released in the previous 7 days like Wild Outlaws by Light and Wonder and Wild Bandolier by Play n Go.

Megaways Slots

21 Casino has a good selection of 165 Megaways slots. You can search by hitting the Slots link then the Megaways button in the sub-menu, or list them all by typing ‘Megaways’ into the search box. The list includes classics like Bonanza as well as lots of variations like Ted Megaways and Genie Jackpots Megaways from Blueprint Gaming.

If you like Megaways games then we also recommend Casumo which has 176 Megaways titles.

Slingo Games

21 Casino also has a small selection of 18 Slingo games. These include Slingo Da Vinci Diamonds, Slingo Starburst and Slingo Cleopatra. If you like this format and want to find more games like these, try our Slingo Sites page.

Game Menu, Search Functions and Game Window

Like the rest of the site the game menu is slick and easy to use. The logos stand out nicely on the black background. Rollover each one and you’ll see the provider, the reels, winlines and volatility. It is a unique feature that will help you find a game you like as you search the long lists. You can also Favourite a game by clicking on the heart icon. This will save it in your Favourite list for quick access at a later date.

As well as searching by categories like New Games and Jackpot Slots there is also a Discover link that opens up more options. Scroll down and you’ll see groups of games like Megaways, Slingo and Last Played.

Or, choose the generic ‘slots’ link from the main menu and you’ll see a sub-menu with a choice of Cluster Pays, Megaways and Sticky Wilds, which is nice but could be improved by more filters. Skill on Net sites, for example, allow you to search by paylines, volatility and stake range. What you can do is hit the Providers link at the end of the menu to bring up a long list of them all, then hit your favourite to list all their available games.

Finally, the slots themselves load up in a frame with the 21 Casino branding. You can view your ‘Level Up’ bar whilst you are playing to check your progress before the next bonus drops. There is also a quick deposit link that opens up the cashier without closing the game down, and you can favourite a game and full size the window from here too.

Slots RTP at 21 Casino

Not all casinos run slot games at the same RTP level. Some providers now offer their games with a range of settings from 85% up to 96%. It is at the casino’s discretion to choose which level they set the games to. We verified 10 games that we know to have multiple RTP settings to see which level 21 Casino run them at. This is what we found:

NOTE: These RTP settings were verified on 23^rd May 2023.

Whilst in this sample all but Book of Dead are running under the optimum RTP, the chosen settings are still at the upper end of the range in most cases. This is standard for UK slot sites now. The only casino we have found where ALL games are set to the maximum RTP is Mr Q.

You can find out more about RTP and why it is important in this guide.

Overall, the slots experience at 21 Casino is very impressive with lots of choice backed up by great functionality to help you find the game of your choice.

Live Dealer 7/10

Live Casino at White Hat Gaming sites is powered by both Evolution Gaming and Pragmatic Play. These are the two most popular live dealer providers in the industry. If you open-up the games you will be playing with 10,000s of other casino players from around the world. There are no exclusive tables at 21 Casino but that is standard for white labels.

The Evolution suite is the busier of the two and certainly offers the biggest selection of tables with more than 150 Blackjacks, 30 Roulettes, Hold Em Pokers, Baccarat AND Sicbo, as well as a wide choice of Gameshows like Crazy Time, Lightning Roulette and Dream Catcher.

The Pragmatic lobby offers similar action though there is no Sicbo and the Gameshow area has fewer formats. What it does offer is Sweet Bonanza Candyland, a popular live version of the famous Pragmatic slot.

Whilst there are no Playtech, Authentic or Stake Logic tables to play at 21 Casino, for most slots players looking to dip their toe into live dealer, there is still enough from Evolution and Pragmatic to be getting on with here.

Loyalty Promotions 6/10

After a quality welcome package and excellent game catalogue, 21 Casino lets itself down somewhat with a very sparse promotions calendar. Aside from the sign up offer the only deal advertised is the level-up program. Every wager you make will progress you along the Level Up bar displayed top right of the screen when you are logged in. Only wagers of 20p or more contribute to your progress.

I really like rewards programs at slot sites, but I do take issue when it is not clear how much you have to wager to reach each new level. It feels arbitrary and open to abuse by the operator who can adjust the rates at any time without acknowledgement. On the plus side you will be credited with spins, super spins, mega spins and ultra spins at each new level and no one is going to argue with more free play. Ultra spins are worth up to £2 on some games making them a nice bonus to have.

There are no other promotions advertised at 21 Casino. This is disappointing but not uncommon at white label sites which don’t offer the same quality of experience as big independent casinos like Casumo, 888 or Leo Vegas.

Cashier Options 9/10

21 Casino is a £10 minimum deposit casino. The cashier offers a standard range of payment services including debit cards, eWallets and Paysafecard. If you want to make a deposit of less than £10 then you could try elsewhere. Casumo or Spin and Win both accept deposits of £5 for example.

There are a few popular payment services missing from the cashier here: Apple Pay, Google Pay and Trustly. If you would like to play with any of these then check our payment guides page for more information.

Here is a summary of the payment options at 21 Casino.

Payout Speed 8/10

We tested the withdrawal process at 21 Casino. Our transactions were not processed super-fast but they were completed in under 24 hours.

• £10 Paypal withdrawal made at 13.20 on Thursday 13.20 – processed on Friday at 12.44 – 23 hours 24 minutes.

This is within 24 hours which is fair, but not as fast as many other sites we have tested. One of the best for fast withdrawals was MrQ.

Customer Support 7/10

The support team at 21 casino can be contacted on live chat and email. There is no phone support.

• Live Chat:24/7 on site
• Email: support@21casino.com

The live chat function was straight forward, though it does require you to enter your full registration details the first time you use it. Make sure you set up a 4-digit PIN with the support agent once you are put through, so you don’t have to add your full details each time.

The response time on live chat was very quick – under a minute on 4 occasions when I contacted the team. However, it felt like the chat was populated by AI bots rather than real people. The answers lacked the personal touch but questions around KYC verification and deposits and withdrawals were all responded to accurately and quickly.

There is no hub of help pages at 21 Casino. So there is no FAQ sections on the site. That is quite typical of white label sites which are often short of the bells and whistles.

KYC Process 8/10

21 Casino use an automated 3^rd party tool called Hooyu to carry out KYC checks on customers who reach the required threshold on deposits or withdrawals. This is quicker and more efficient than sending documents on email for a staff member to review. With this system, if you submit complete scans of the right documents checks are done in minutes.

It can feel a bit strange being re-directed to another site to upload scans of personal documents like this. if you want to know more about how Hooyu works you can visit their website here.
