21 Casino is one of the earliest White Hat Gaming sites, from 2015. It sports a high-end casino theme that looks superb and it offers fair, safe and secure gaming thanks to a UK license. Here is a summary of the strengths and weaknesses as uncovered in our review.
Strengths
- High value match bonus – this site will really suit those looking to make a significant first deposit as they are matching by 100% up to £500. That’s one of the biggest available bonuses in the UK right now.
- Big slots list – there are more than 4,500 slots from a very diverse range of providers. Whether you want high variance mayhem with plenty of features or a simple low variance game, you’ll find it here.
- Extensive jackpots range – for progressive jackpot hunters there are plenty of options from Mega Moolahs to Dream Drop games.
- Very smart website – I loved using the website at 21 Casino. It looks great, loads smoothly and is functionally very good.
- Good range of responsible gambling tools – there are lots of ways to manage your own spend with deposit limits and time outs.
- £10 minimum deposit – unusually for a White Hat site you can deposit from just £10, and that qualifies you for the welcome bonus too.
Weaknesses
- High wagering requirements – offsetting that big sign-up offer are some of the strictest wagering terms you will see anywhere. You need to wager 40x the bonus AND deposit value to release your bonus balance.
- Loyalty program is not transparent – whilst there are level-ups for those who wager enough, it is not clear how much you need to spend to reach the next level each time.
- Game menu could be more sophisticated – I would like to have seen more powerful search and filter tools to help explore all those slot games. Filters for volatility, paylines and max win for example.

Steps To Register and Claim Your Bonus At 21 Casino
- Hit the yellow ‘Begin’ button on the home page or the ‘Sign Up’ button at the top of the screen.
- Enter your details in the registration form. You’ll need to provide a username and password, email, full name, date of birth, address and mobile number. Personal details are checked using 3rd party verification tools in accordance with gambling regulation so make sure you put these in correctly or your account may be rejected.
- If you are asked to provide documents to formally verify your ID and address, upload or email them as requested.
- You can set your own deposit limits at this point if you wish to.
- Click the yellow ‘Deposit’ button and choose your payment option from the list.
- Enter a deposit value. The minimum is £10.
- Choose the welcome bonus from the list of options to ‘opt in’.
- Confirm your deposit.
- The bonus funds will be credited to your bonus balance and you’re ready to play.

Sign Up Offer Terms
This welcome bonus is subject to terms and conditions. Make sure you understand them before you opt in. If you are not comfortable with the wagering requirements or cashout limits then you can choose not to accept the bonus.
Your bonus funds will appear on a bonus balance which is represented by a small gift box icon in your account. This is separate to your cash balance. You will play your cash balance first with any winnings generated paid back onto it. Only when your cash balance hits zero do you move onto the bonus balance.
Once you start playing with your bonus funds any wins are paid back onto the bonus balance. You need to wager 40 times the value of the bonus plus the deposit before the bonus balance is transferred to the cash balance. So, if you have made a deposit of £20 and received a £20 bonus then you will need to wager £1,600 (£20+£20 x 40). If you can reach that target without losing all your bonus funds then you have some cash to withdraw.
Wagers on slots, scratchcards and keno contribute 100% towards meeting the requirements. Wagers on table games count 10% and video poker, 5%.
21 Casino also set a limit of £5 on bets with bonus funds. If you go over this you will forfeit your winnings when you come to withdraw. White Hat Gaming sites are very strict on this. There are lots of reports on forums and review sites from players who fell foul of the bonus terms and had their winnings confiscated!
Is This A Good Deal?
This is a big match bonus with a high cap at £500 and a nice low minimum deposit threshold of £10. That makes it a competitive offer and one that will suit players who like a nice simple deposit match. This is offset by the wagering requirements which are very tight at 40x bonus plus deposit. And those who enjoy some free spins in their welcome offer will need to try elsewhere.
Promotions and Loyalty Program
21 Casino has limited promotions for regular players. There is a loyalty program with level-ups and a few seasonal offers.
| Promotions | Details | Key Terms |
|---|---|---|
| Sign Up Offer | 100% up to £500 match bonus | Min deposit: £10; WR: 40x bonus plus deposit |
| Loyalty Program | Earn points for wagering, complete progress bar to reach next level, earn bonus at each new level | WR: 35x bonus funds; Max Win: £200 from bonuses |
| Seasonal Deals | Free spins, bonuses and races advertised on website, email and SMS | Max Win: £100 from free spins; Winnings credited as bonus funds |
Level Ups – Earn Bonuses For Wagering
21 Casino has a very simple rewards system. Every bet you place takes you further up your progress bar until you complete and unlock another level. At each new level you are rewarded with a bonus or free spins. The size of the bonus is dependent on the average wager you made whilst completing the level.
The nice thing about this scheme is its very simple and I can easily view my progress in the bar at the top of the screen whilst I’m playing. You can see that in the screenshot below. The downside is, it’s not made clear how much you must wager between each level, so it’s not entirely transparent.

Seasonal Promotions – Races and Bonuses
21 Casino does also run seasonal promotions which are advertised on the website, on email and SMS if you opt in.
For example, at the time of writing there was a Spooky Hours promotion for Halloween where players could claim up to 30 free spins on Ghost of Dead every day for a week by playing during the Spooky Hours (18:00 to 23:00). Every 50 spins of 20p or more gets you 30 spins.
At the same time there was a slots race running for one week with the top 30 wagering players earning a share of £4,000, divided as follows: 1st: £1,000, 2nd: £700, 3rd: £500, 4th: £200, 5th: £150, 6th-9th: £100, 10th-30th: £50.
I like the free spins deal here. It means you can claim some extra spins quickly and at a good rate - you get 30 free spins just for playing 50 spins! The races are fun too, but it will be tough ask to get into the top 30 as the promotion is shared across 4 White Hat Gaming sites so there will be a lot of players going for it.

Here are 10 of the best and a selection of their games.

There are also over 200 Megaways games and a huge selection of Cluster Pays slots like Hand of Anubis, Moon Princess and Fire Hopper.
Tip For Browsing The List At 21 Casino
If you scroll over a game logo you’ll see the Reels, Winlines, Provider and Volatility rating (1 to 5). This can help you find a game you might like. You can also click the heart icon to save the game to your favourites.
There are too many to name them all, but I’ve found 15 here that I think give a flavour of the range of styles and pay models on offer at 21 Casino.

|---|---|---|---|---|

| Lil Devil | Big Time Gaming | 4,096 win ways | 96.43% | 50,000x |

*RTP verified at 21 Casino - games may have different RTP settings at other casinos
RTP Rates At 21 Casino
RTP rates on slots vary from one casino to the next. We spot-checked some popular slots to see what RTP setting 21 Casino had chosen. The following games have a range of between 88% and 96%. In each case, 21 Casino were choosing to run the games at around 94% which is just under the optimum.
Book of Dead – 94.25%
Razor Shark – 94.06%
Big Bass Bonanza – 94.02%
Reactoonz 2 – 94.2%
Itero – 94.24%
These RTP settings are good, if not optimal, for the UK. Many operators here now run games at closer to 90% or even less.
Jackpot Slots
21 Casino offers a good selection of progressive jackpots too. All the big ones are here, except for NetEnt’s Mega Fortune. In total you can play more than 200 games from 5 major networks - King Millions, Mega Moolah, WowPot, Jackpot King and Dream Drop. There is a big variety of themes and styles to enjoy whilst chasing down those big wins.
Here are 5 popular choices:
| Jackpot Slot | Provider | Seed Value | Features |
|---|---|---|---|
| Dream Drop Diamonds | Relax Gaming | £1,000,000 | Cascading reels, prize ladders, jackpots |
| Mega Moolah | Games Global | £2,000,000 | Free spins, wilds, jackpots |
| The Goonies Jackpot King | Blueprint Gaming | £500,000 | Wilds, expanding wilds, jackpots |
| Sister of Oz WowPot | Triple Edge Studios | £2,000,000 | Jumbo blocks, free spins, jackpots |
| Gold Blitz King Millions | Games Global | £2,000,000 | Free spins, multipliers wilds, jackpots |
Live Dealer
The live dealer area is powered by Evolution Gaming and Pragmatic Play. In my opinion that is all you need for a quality experience. Between them they offer the highest quality streaming of blackjacks, roulettes, pokers, baccarats and gameshows. Some of the best are in the latter category including Monopoly Live, Sweet Bonanza Candyland and Crazy Time.
Table Games
Whilst many players preference is for live table games, there are still some who prefer the virtual experience that kicked the whole internet casino age off. 21 Casino caters to these players with games from Microgaming, Switch Gaming, Inspired and Relax Gaming. There are a mix of traditional and new formats of blackjack and roulette like Roulette Wheel of Thunder and Space Invaders Roulette.
Slingos
21 Casino also has a small selection of 50 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.
Other Games
The selection of more than 50 alternative casino games is also worth checking out if you sign up at 21 Casino. These are entertaining options like plinko, ballon races, scratchcards and virtual racing.
Website and App Experience
9/10
I love the website at 21 Casino. Whilst many white label slot sites can appear rough around the edges, this one has a superior quality to it. The logo is refined with a crown motif whilst 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 – available via a link in the footer - outlining the team’s background and commitment to fair and secure gaming. It adds to the overall feeling of integrity.

The simple design style is carried through into the account pages and important information is easy to find on the site too. Links to promotional terms, legal information, complaints procedure and responsible gambling are all clearly displayed on either the main menu or footer menu.
I spent time signing up, depositing and playing games at 21 Casino. The site always loaded quickly and the games played without any lagging.
Playing 21 Casino on Mobile
Unlike other White Hat Gaming casinos this one does NOT have a mobile app version. However, the site has been optimised for mobile. I tested it on an iPhone 12 with iOS 18 – so not the newest configuration – and the site and games loaded perfectly and in good time.
Banking
7/10
21 Casino is a £10 minimum deposit casino. The cashier offers a good 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. Spin and Win accept deposits of £5 for example.
Whilst most services are accepted, there are a few popular options missing including Apple 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.
| Payment Option | Min Deposit | Deposit Fee | Min Withdrawal | Withdrawal Fee | Withdrawal Time* |
|---|---|---|---|---|---|
| Visa, Mastercard | £10 | None | £10 | None | Up to 5 days |
| Paypal | £10 | None | £10 | None | Instant |
| Skrill | £10 | None | £10 | None | Instant |
| Neteller | £10 | None | £10 | None | Instant |
| Trustly | £10 | None | £10 | None | Up to 5 days |
| Revolut | £10 | None | £10 | None | Up to 5 days |
| Neosurf | £10 | None | N/A | N/A | N/A |
| Bank Transfer | £10 | None | £10 | None | Up to 5 days |
| Paysafecard | £10 | None | N/A | N/A | N/A |
*Withdrawal time after processing by 21 Casino
Payout Speed
Withdrawal times at White Hat Gaming casinos like this one are reasonable, but not super-fast. Once your account has been verified then you can expect payments to be processed within 24 to 48 hours on most occasions. However, most sites on this network won’t process your withdrawal at weekends, so sometimes you might be waiting up to 72 hours.
Remember too that once 21 Casino has processed your withdrawal it will then go to your payment provider. eWallets will make the funds available almost instantly whilst banks may take a few days.
I tested a withdrawal here to Paypal and it was completed in under 24 hours. The payment was £10 made on at 13.20 on a Thursday 13.20. I received the funds on the Friday at 12.44 – a total of 23 hours 24 minutes.

Know Your Customer (KYC) Checks
KYC checks are carried out on all customers at 21 Casino. This is a condition of the operator’s license. Checks take place on registration and when thresholds are met for deposits and withdrawals – normally around £1,000 to £2,000. Checks at registration may be done automatically using 3rd party tools, but for later checks you may be asked to provide documents to formally prove your ID, age, address and source of funds. These can be uploaded via your account page.
What Documents Will I Need To Provide?
One or more of the following documents may be requested for KYC checks:
- Driver license – to prove your ID and age
- Passport – to prove your ID and age
- Utility bill – to prove your address
- Banks statement – to prove your address / source of gambling funds
- eWallet statement – to prove your address / source of gambling funds
- Payslip – to prove your source of gambling funds
- Bank card – to prove you own it
Whilst you are waiting for your documents to be checked a withdrawal will remain pending and your account may be locked temporarily. Try to be patient, most checks are completed within 24 hours.
Customer Support
9/10
Contacting Support
- Email (24/7) – support@21casino.com
- Live Chat (24/7) – via the ‘Live Chat’ link in the footer
- Phone Support – Not available
- FAQs – via the ‘Live Chat’ link in the footer – then head to the ‘Help Center’
The customer support team at 21 Casino can be contacted on live chat or email. The service is available 24/7. But there is no phone support option. It’s a good service in my opinion, mainly because it is not AI-driven. There are real people at the end of the line and they are helpful and courteous. Response times can be up to 5 minutes but they are often faster outside of the busiest hours.
White Hat Gaming sites also have a Help Center which you can reach via the Live Chat link in the footer. This is like an FAQs with lots of useful information presented in categories like Technical or Deposits. It’s a good option if you don’t want to wait to speak to an agent.
Player Protection and Trust
8/10
21 Casino operates under the UK license of White Hat Gaming. The operator is required to maintain high standards for safety and security to protect its customers. All the following features help to achieve this:
- Responsible gambling tools – players can set limits on their own play based on their budget and time constraints. Deposit limits, time outs and self-exclusions are all available.
- Transparent Complaints Procedure – 21 Casino have published a page entitled ‘Complaints Procedure’ which is accessible via the site footer. It explains how to raise a complaint, how quickly the team commit to finding a resolution, and what will be done if no resolution can be found. An adjudicator, eCorga, is nominated as a dispute resolution service to help in these cases. They are impartial and free to use.
- Game Testing and RTP – all games are provided by licensed developers. They are audited by approved test houses for fair play. Verified Return to Player rates are published in the games.
- Security – the site uses a Secure Socket Layer (SSL) connection to protect personal and financial data. All information is encrypted to prevent it being intercepted and read by anyone other than the operator. All payment services are also licensed by the Financial Conduct Authority, the UK regulator responsible for setting and upholding standards for financial services.
- Privacy Policy - the casino has a Privacy Policy page published on their website that outlines how customer data is collected and retained and what it is used for. This is all in accordance with UK law.
- Fair Terms and Conditions - every bonus or promotion is subject to clear terms and conditions that can easily be located on the website. Wagering requirements are strict in some places but they are not unreasonable and fall within the normal range for bonus offers at UK casinos.
- Know Your Customer Checks - these are carried out to prevent fraud and under age gambling but also to protect players from problem gambling. Source of wealth checks are an important part of this process, ensuring that players do not spend beyond their means.
Accessing Responsible Gambling Tools
21 Casino offers plenty of options to set limits on your own play. You can access these by clicking the shield icon which appears at the top of every page once a player is logged in. They include the following:
- Deposit limits – by day, week or month
- Game time reminders – popups that let you know how long you have been logged-in for
- Time out – temporary exclusion from the site for up to 6 weeks
- Account closure – close your account by contacting support. This is reversible.

What Others Say - Reviews From Players and Consumer Sites
There are several popular online platforms where players can leave reviews of their experiences at casinos. We look at TrustPilot, CasinoMeister and Ask Gamblers to find out what people are saying about 21 Casino.
TrustPilot
Average score of 1.9/5 from 119 reviews (5 star -How Does 21 Casino Compare With Other UK-Licensed Casinos?
To finish, we compare 21 Casino with 2 competitors across the main features of the site. We’ve added our own thoughts on the relative strengths and weaknesses of each one underneath the table. 14%, 1 star - 80%).
This score is described as ‘Poor’ on the Trustpilot website. However, the number of reviews is very small – 119 since 2020 - so I would not read too much into this rating. Many reviews appear to be from customers who have had a losing streak and want to discredit the casino as a result. Remember, all games at 21 Casino are audited by approved test houses so game results are always random and the games are certainly not rigged.
There are a few posts about slow withdrawals and delays caused by account verification. However, they are not significant in number. On the flipside there are a few comments from players who have had a good experience, including these ones:
“Won £3500, withdrew funds within 48h, customer support were helpful and great experience, thank you” – read this review.
"I don’t know why everyone says they don’t pay out as I won £4800 and was payed out within 2 days. Very good casino!" - read this review.
Ask Gamblers
7.3/10 on the in-house Casino Rank algorithm (an automated ranking tool that bases its scores on a combination of critieria including the games, cashier, support hours and player reviews at AskGamblers). This is a fair score and it aligns with our own good rating of 21 Casino.
5.1/10 from 56 player reviews – it would be wrong to read too much into this score as there are only 56 reviews and they go back 10 years, but with nothing from the last 2 years. The comments show a mixed experience for players at 21 Casino.
Casinomeister
In-House Review Score: 7/10
Player Rating: 7.7/10
Both the writers and players at Casinomeister give 21 Casino a good score. The in-house review picks out the website design, line up of games and range of payment options for praise. Interestingly, there is no reference to 21 Casino is any forum posts at Casinomeister which suggests it is not a popular or well-used site.
What Do These Reviews Tell Us?
The small number of reviews of 21 Casino on Trustpilot and Ask Gamblers, and the lack of any forum discussions, suggest that this site may not be getting many customers now. It may have been superseded by newer White Hat Casinos like 247Bet or Blackjack City. It’s hard to read anything into such limited coverage but a few positive comments on Trustpilot and the good in-house review scores at Ask Gamblers and Casinomeister seem to back-up our own findings that this is a trustworthy and reliable site with great games.

- Casumo makes an interesting comparison because it is a big budget white label. The website and mobile app are far superior to 21 Casino and Pub Casino but there are all the other factors to consider too, of course.
- 21 Casino’s strict wagering terms offset the high value of its bonus. The price to pay for a £500 match is those 40x bonus plus deposit wagering requirements. Pub Casino offers much better terms at 40x the bonus ONLY, but the cap is much lower at £100. And if you prefer an offer with free spins you’re better off at Casumo.
- 21 Casino and Casumo perform much better than Pub Casino across the games categories – they have many more providers and a far more diverse range of slots. 21 Casino holds its own against Casumo with an equal number of games and suppliers. If you want a lot of choice, you should pick one of those two.
- 21 Casino is a traditional casino site without sports betting. Its design will appeal to those who like classic table games and don’t want the distraction of a sportsbook on the site. By contrast, both Pub Casino and Casumo have evolved to offer the betting experience as well and they offer a wide range of markets.
- All 3 casinos offer low minimum deposit thresholds at just £10.
- Withdrawal times at both Pub Casino and Casumo outperform those at 21 Casino. Pub Casino has a good reputation in this area as we discovered in our research, with many withdrawals processed in just hours. Casumo also has fast withdrawals, with some turned over in minutes once verification checks are completed.
- 21 Casino’s loyalty program is basic and it doesn’t come close to what you find at Casumo which has built its reputation on fully integrated loyalty promotions with level-ups, trophies and achievements. If you want the gamified casino experience, you should go there.
- Pub Casino’s operator, L and L Europe, has the best reputation for its customer support service (phone included) with a friendly team and fast response times. The other two sites are OK in this area, but not great.
Conclusions
21 Casino – play here if you want a high value match bonus (but be ready for those tough wagering terms), a huge slots list, and a website that looks like it was built for VIP blackjack players.
Pub Casino – for a more down-to-earth website style, with fewer games and a smaller sign-up deal but with much friendlier wagering requirements, try Pub Casino.
Casumo – for a big, independent brand with a match bonus and free spins deal, awesome website and app with lots of integrated loyalty features, real time reel race leaderboards, fast withdrawals and the sports betting options, try Casumo.
Our Verdict
21 Casino is one of the more sophisticated White Hat Gaming sites we have covered thanks to its elegant stylings and VIP vibe. It has the same qualities as other sites on the label including a very strong slots selection, good live dealer tables and a solid sign-up deal. The experience could have been improved by more loyalty bonuses and some free spins added to the welcome package, but on balance 21 is an above average white label with a lot to offer.Overview
