The site is powered by Whitehat and is owned and operated by Caddell Limited. 21 Casino holds a license from the UK Gambling Commission, and since it launched in 2015, its popularity has continued to grow. We were up for a superior gaming experience, so we've put this casino through its paces to see what it has to offer.
Review Results
Slot Game Providers and Software
21 Casino offers hundreds of incredible slots from a variety of gaming developers. Here, you'll find classic and up to date titles from the likes of NexGen Gaming, Microgaming, Aristocrat, NetEnt, Betsoft and Blueprint Gaming.
Design & User Experience
The first thing that caught our eye during our review was just how well-designed and elegant 21 Casino is. The layout is smooth, making it effortless to find what you're looking for. With clear graphics and just three tabs – Home, Games and Promotions – everything about this casino is easy. It's clear that a lot of thought has gone into the functionality and design of the platform.
Signing up is super-fast, too. All we did was click on the Sign Up button and completed the registration form. You need to activate your account via email, and that's it. You're on your way to a stunning welcome bonus, extra spins and hours of online casino entertainment.
21 Casino's Mobile Experience
21 Casino has certainly stepped things up with its mobile app. If you're constantly on the move but don't want to miss out on great jackpots and exciting bonuses, this is the way to go. Whether you download the app for Android or iOS, or just log in through your device's browser, you can look forward to the same easy-going experience as you get on the desktop version.
Slot game selection
Slots definitely dominate at 21 Casino. With amazing graphics, exciting features and big wins, we were glad to see that the slots have been neatly categorised into New Games, Top Games and Slot Games. There's also a search bar if you simply want to head straight for your favourites. You'll find tons of classics and new titles at 21 Casino. From Agent Valkyrie to Dead or Alive and even Silent Run, there is plenty to pick from.
Does the casino offer progressive jackpot slots?
At the time of our review, 21 Casino has more than 30 exciting progressive jackpot slots to play. We especially like the fact that if you hover your mouse over a game, you'll find information like that game's RTP, win lines, volatility and reels. If you're on the hunt for big wins, 21 Casino makes sure you're spoiled for choice with titles like Divine Fortune, Paws of Fury, Genie Jackpots and Mega Fortune to name a few.
Deposit and Withdrawal Options
21 Casino accepts a variety of different payments for both deposits and withdrawals. These include wire transfers, debit cards, Paysafecard, Skrill, Neteller, Bankwire, Trustly and Interac. Both the minimum deposit and withdrawal amounts are £10, while the casino allows you to withdraw up to £25,000 per week. E-wallet withdrawals take around an hour to process, while wire transfer takes up to 6 business days.
Exclusive slot bonuses and promotions
When we signed up at 21 Casino, we were warmly welcomed with a 121% match deposit bonus and 21 spins to spend on Book of Dead. The welcome bonus is worth up to £300 and requires a minimum deposit of £10 to trigger. The bonus also carries a decent 35x wagering requirement and must be used within 30 days of receiving it. Carry on playing at 21 Casino, and you'll find plenty more promotions coming your way, complete with reload bonuses, cashback offers and bonus spins that are regularly updated.
VIP & Loyalty Programmes
There's not a whole lot of information on the casino's VIP scheme, but they do run a loyalty scheme where you build up points every time you place a bet. Once you've accumulated 200 points, you'll get a £1 bonus. You can exchange up to 10,000 points a day, which equals a £50 bonus.
Customer Support & Security
If you're ever in a pickle using 21 Casino, help is on hand. The live chat function is available 24/7 and the team provides instant responses. If you prefer, there is an email address you can use.
This casino has turned every stone to ensure your experience on the platform is safe. It makes use of the latest security technology and SSL encryption from RapidSSL to promise that both your financial and personal data is always secure.
Responsible Gambling
21 Casino is passionate about gambling responsibly, and to express this, the casino has implemented several player protection tools to help manage and restrict spending. You can take a temporary break, freeze your account, set time-outs or self-exclude. You can also impose daily, weekly and monthly deposit limits. The site has an entire page dedicated to responsible gambling where you'll find information, advice and tips for managing your gaming habits.

Conclusion
We had so much fun trying out 21 Casino, that we think everyone should have a go. The welcome bonus is extremely generous with decent wagering requirements and bonus spins to boot. The game selection is exceptional, especially with so many top-notch developers on board, and the casino is fully licensed, regulated, safe and secure. It's clear this casino cares about its players.
It would be nice to have more information on 21 Casino's VIP program, and perhaps they'll work on adding a support phone line and FAQ page in the future, but there's not much we can niggle about.
Overall, this online casino provided a fun, immersive and super-responsive online gambling experience. Sign up and see for yourself!
