21 Casino Review

21 Casino has been on the scene since 2015 and it has managed to keep its offering fresh and modern in the intervening years. Its online casino games have always been a priority and it has titles from a multitude of leading developers.

This offering is under the management of White Hat Gaming, that also manages other casino brands like Casimba and DreamVegas. The platform is licensed by the reputable United Kingdom Gambling Commission, the Swedish Gambling Authority and the Malta Gaming Authority.

The selection of games is impressive, but has it sacrificed quality for quantity? This what we look at and more in this review.

500+ games from top quality developers Debit card withdrawals are a bit slow
Desktop and mobile platforms are sleek and perform well No customer support phone number
Welcome bonus is well-sized and attainable

Welcome Bonus

If you are a new customer at 21 Casino, you can avail of the welcome bonus offer. This allows you to get your first deposit matched 121%, up to a max bonus of £300. With most deposit bonuses being a 100% match, you are getting more bang for your buck with this offer.

You will also get 21 bonus spins for the Book of the Dead slot as soon as you have opened your account. We are always fans of no deposit bonuses such as this one as we can try out a platform without putting any of our own money on the line initially.

There are some finer details to consider when assessing this offer. For the bonus spins, you must wager them x35 within ten days before being able to cash out. There is a max bet of £5 allowable and you can only win a max of £100 through these spins.

For the no deposit bonus, the minimum deposit amount is a low one at £10. The same wagering requirements are in place for this offer except you have 30 days to meet your target. These wagering requirements are very achievable in our eyes.

Do note that if depositing via Neteller or Skrill, you cannot avail of this deal. In terms of games that contribute towards the wagering requirements, most slots fully contribute, whereas others only contribute 20%, while some contribute 0%. For table games, there is a 10% contribution, 5% for video poker and 0% for other games and jackpot games.

The registration process at 21 Casino only takes a matter of minutes. You will firstly need to pick a username, enter your email address, choose a password, select your country and confirm that you are at least 18 years old and accept the site's terms and conditions.

Then you need to enter your full name, date of birth and gender followed by your full address. Finally, you enter in your phone number and a verification email will be sent to you.

Do note that you will not be able to withdraw funds from your 21 Casino account until you verify our identity. This entails sending them proof of address and proof of identity by email. It can take up to 48 hours for this process to be completed.

All licensed operators now require customers to complete verification and to be honest, we would be worried if they did not request this from you at some stage.

Your withdrawal options are a bit more limited, being Visa, MasterCard, Maestro, Skrill, Neteller and bank transfer. For the e-wallet options, you will be waiting about 24 hours for the withdrawal process. A bank transfer withdrawal can take as much as 72 hours, with debit card withdrawals taking the longest at up to 5 days.

If you manage to win it big, there is a weekly withdrawal limit in place of £25,000.

Desktop/Mobile Experience

There is a classic yet slick feel to the 21 Casino. It has a minimalist design which doesn't overcomplicate anything. What you see is what you get, we had no hassle navigating around and finding what we were looking for.

When it comes to navigating through the different games on offer, you can use the handy filtering system. You can choose by provider and popularity and you can even quickly see the RTP of a game and its volatility by hovering over it. You can also use the search bar if you have a specific game in mind.

The mobile version of 21 Casino is equally as appealing. It is a seamless experience no matter if you are using an iOS or Android device, with the navigation system being very straightforward. As there is no dedicated app for either Android or iOS devices, you have to play through your mobile's web browser.

The gameplay is smooth and you do not lose out on many games or features when going from the desktop version to the mobile offering. The titles have been optimized for play on the mobile, so you will not be dealing with any glitches or distorted games. We certainly see 21 Casino's mobile offering as being right up there with the best today.

Game Variety at 21 Casino

We were impressed at the selection of games that are to be found at 21 Casino. There are slot titles from some of the best developers including Quickspin, NetEnt and Microgaming to name but a few. In total, there are a few dozen different developers that have games on offer at 21 Casino.

There is something for every taste and preference with over 500 slots to choose from. Some of the more popular slots titles include Starburst, Jack and the Beanstalk and Golden Leprechaun Megaways. All of these games can easily be played without any pop-ups on your browser.

The same selection headache exists for the table game offering. This includes 17 variants of roulette, 30 variants of blackjack, 19 types of table game poker, as well as the likes of Pontoon, Baccarat, Sharp Shooter and Red Dog.

For those players that are looking to win big, you have a healthy choice of progressive jackpot slot games to choose from (50 options). Some of the more popular options include Mega Moolah, Divine Fortune and Mega Fortune. You are in with a chance to win a seven-figure sum with a few of these titles.

Finally, there is a selection of side games on offer, such as a Deal or No Deal scratch game, Virtual Soccer and Lucky Gems.

Betting Limits

There is a wide spread of betting limits on offer at 21 Casino no matter if you are a high roller or a more casual player. You can bet as little as £0.10 per spin on slots games, going all of the way up to £500 for a single spin. For table games, you can choose from options that are low, medium or high stakes. This allows you to bet as little as £0.01 per hand or as high as £5,000 per hand.

Return to Player Percentage

The return to player percentage (RTP) of a game is in theory how much return you will get from a given game. For example, if you bet a total of £100 on a slot game that has a 95% RTP, then in theory you will have a total return of £95.

At 21 Casino, you can quickly see the RTP for each game by simply hovering over the given game on the desktop platform.

On average, the slots titles on offer will have an RTP of 96%-97%. Tables games will have RTPs closer to the 99% mark as there is less of a house edge in these types of games. Finally, the more novelty type of games will have RTPs that are less than 95% usually.

VIP Program

There is a VIP program at 21 Casino that you can only enter if you get an invite. This program allows you to earn a variety of different perks, such as cashback bonuses and free gifts.

Customer Support

At 21 Casino, you only have a couple of options if you want to get in touch with the customer support team. You can send them an email or use the live chat function. There is no phone number available for you to ring and the FAQ section is well hidden away.

We were happy to discover that the live chat line is supported 24/7 so you can always get your more straightforward issues sorted no matter what time it may be. If your issue is a bit less urgent or less complex, then sending the team an email will be the better option. You can expect a reply usually within a few hours.

Responsible Gambling Features

21 Casino takes responsible gambling very seriously. It has a page dedicated to the subject, which details the various features you can activate on your account if you are having an issue with gambling. It also provides you with helpful advice and links to useful resources and help organizations.

Some of the player protection tools that are on offer at 21 Casino includes deposit limits, duration limits, hourly reality checks, temporary time-out blocks, account closure, access to your account history and self-exclusion.

Our Verdict

The 21 Casino offering really ticks all of the boxes for us. We were very impressed with the massive selection of slots and table games from some off the best developers in the game. The welcome offer is also well sized and the wagering requirements are fair. Mobile players are well looked after and both desktop and mobile players have access to sleek and seamless platforms. This is definitely a good fit for all types of players.
