Our 21.co.uk Casino Review – iGN Rating 81%

Developed in 2013 and acquired by LeoVegas in 2018, 21.co.uk is fully licenced by the UK Gambling Commission and owned by the one of the most trusted names in UK gaming. I tested the casino out thoroughly, using both the desktop and mobile platform, playing games and contacting support so I could get first-hand player experience. 

My first impression was good and I especially liked the clean, uncluttered user-friendly platform. There’s a simple drop down menu with quick-links to key areas and tabs for casino and live casino at the top. This, for me, is much better than non-stop pop ups and overbearing graphics. Once in the casino, the games were all laid out well with filters at the top and arrows to extend each section. Overall, I thought it was a well-organised casino with a nice clean aesthetic. Now let’s take a look at the key strengths and weaknesses I found.

What We Liked

  • Streamlined Platform: 21.co.uk is sleek, streamlined and easy to navigate. No fancy graphics, pop ups or endless scrolling promotions to detract from the player experience. In my opinion, this clean design shows that players are put first. 
  • Games Library: With 2000+ games, 21.co.uk is around average for UK online casinos in terms of quantity. However, with games from over 65 providers, the quality and variety of games far exceeds many of its competitors. Slots players, in particular, will love the selection on offer.
  • Trustworthy: 21.co.uk is licensed and regulated by the UKGC, plus, as part of the multi-award winning LeoVegas group, players can have extra reassurance that it’s all above board. I was particularly impressed with the strong safer gambling section.

What We Disliked 

  • Bonus Offers: The site is lacking in ongoing bonus offers for existing customers. I would like to see more regular reload promotions and free spins offers to make me want to come back and play. 
  • High Wagering: The welcome offer comes with 40x wagering. That is a little higher than many sign-up offers, particularly when the maximum value is just £50. 
  • Banking: With just 5 banking options, this is below the usual 8 -10 that most other online casinos offer. Plus, withdrawals can take up to 3 business days which isn’t competitive against instant payout casinos.

21.co.uk Casino Bonus and Promotions 

New customers can make the most of the 21.co.uk casino welcome offer. However, existing customers might find this area a little bit lacking, I certainly did! Here’s everything you need to know about 21.co.uk promotions.

21.co.uk Casino Welcome Bonus

The 21.co.uk casino welcome bonus gives new players 100% deposit match up to £50 and £6 in live casino chips. It does, however, come with terms and conditions you must be aware of.

21.co.uk Casino Review

To be eligible you need to deposit a minimum of £10 within 7 days of registration. Before making your first deposit, make sure you opt in to the welcome offer. This can be done at the registration stage or by opting in under the promotions tab. 

Your deposit amount then needs to be wagered 40x in live casino games within the next 7 days. Wagering contributions vary per game. Once wagering is complete, you’ll be awarded the 100% match up to £50. The casino chips will be given £2 per day for 3 days and are eligible on select games. 

If I compare the 21.co.uk welcome offer to other sign up bonuses on the market, BetMGM and Slots Magic both offer higher deposit matches for lower wagering. (Up to £200 and £300 with 30x wagering). Plus both of these offers come with free spins thrown in too.

However, there are welcome offers out there with higher wagering, for example, both Casino Kings and Vegas Paradise have 50x wagering. One thing the 21.co.uk offer has going for it is that wagering has to be done on live casino games rather than slots. Live casino games like blackjack have higher RTP’s than most slots so this can balance out the high wagering.

Just make sure you check out the full terms and conditions so you know which games are eligible for wagering.

Other 21.co.uk Promotions

As previously mentioned, this is an area that needs improvement. While completing this 21.co.uk casino review, I could only find one other promotion as below:

  • Gigantic Jackpots: A networked promotion among all LeoVegas sites where you can win a Mini, Minor, Major and Mega Jackpot on hundreds of slots by betting a minimum of 10p.

21.co.uk Casino Games Review

Let’s now take a look at the 21.co.uk games selection to see how it compares to the best UK online casinos.

Game providers

Slots players, like me, will love the wide variety of games providers at 21.co.uk. From the biggest and best to the most niche studios, there’s something for everyone. Alongside giants such as Pragmatic Play, Blueprint, Play’n Go and Netent, you’ll also see games from Electric Elephant, Golden Rock Studios and Bang Bang. To put this into perspective, most UK casinos will offer between 20 – 40 games providers, while at 21.co.uk there’s over 65.

Slots

With just over 1500+ slots, 21.co.uk has the usual quantity of slots you would expect from an average online casino. However, because the slots come from both big and small studios, it offers a wide variety of both classic and rare titles. 

All of the UK’s favourite slot games are here – Big Bass Splash, Immortal Romance, Starburst, and Sweet Bonanza, to name a few. However, if you fancy something a little bit different, then why not try Sherlock Bones by Electric Elephant or Friends: The One with Multi-Drop by Playzido.

I had a good look around the catalogue and found it easy to navigate using the handy tabs. You can search under headings such as ‘Popular’, ‘Megaways’, ‘Classic Slots’, ‘Jackpots’ and even ‘New Games’ for all the new releases.

Table Games and Live Dealers

If you’re wanting to play virtual table games, then 21.co.uk probably isn’t the place for you. In fact, I could only find a couple of games in the library such as video poker and auto roulette.  However, if you enjoy live table games, then 21.co.uk casino will be right up your street!

Offering around 60 live blackjack tables and over 50 live roulette tables, you’re spoiled for choice. Add in some live Baccarat, Poker, Dice Games and Game Shows and you can see why live casino players will be happy here. There’s even some Exclusive 21.co.uk casino games such as 21.co.uk Majestic Wheelshow if you fancy it.

Responsible Gaming at 21.co.uk Casino

It’s clear from writing this 21.co.uk casino review, that player safety is a high priority. I was quite impressed with the range of safer gambling tools available and the overall standards across the platform. Let’s take a closer look at how the KYC process works and my safety index rating for this site.

Their KYC Process Explained

It is vital that all online casinos licensed by the UKGC follow a Know Your Customer (KYC) procedure for players. At 21.co.uk, you are asked for your details and for them to be verified through ID to ensure you are of legal age and that you are who you say you are.

This is all standard procedure for regulated sites and means that 21.co.uk is upholding the correct standards. Verification shouldn’t take longer than 48 hours, but must be done before your first withdrawal. My advice is to do it straight after registration to prevent any hold ups further along the line.

Is 21.co.uk Casino Legit?

21.co.uk Safety Index

Yes 21.co.uk casino is legit. In fact, I’ve given it an overall Safety Rating of Excellent. As a licensed UKGC casino, you can be reassured of its safety and trustworthiness. But more than that, the platform uses secure SSL encryption to protect user data and provides an extensive range of responsible gambling tools. These include spend limits, loss limits, wagering limits, session limits, reality checks, time outs, and self-exclusion options.

There’s a self-assessment questionnaire, advice on staying in control and links to over 12 gambling support services. This, along with 24/7 help from customer support, means it’s earned an Excellent safety rating for overall safety and player protection.

Player Experience at 21.co.uk Casino

So far in this 21.co.uk casino review, we’ve looked at bonus offers, games, security and overall pros and cons. Let’s now take a look at the user experience.

Desktop and Mobile Performance

Whether you’re playing on desktop or mobile, 21.co.uk casino is sleek, quick and easy to navigate. The desktop platform is uncluttered, has clear game filters and you can use quick tabs to find promotions, support services and safety gambling tools. The whole process is streamlined. 21.co.uk casino even offers handy ‘how to play’ guides for some of their games.

On mobile, you can access the casino via your web browser or you can download the dedicated app. Available for both iOS and Android users, the app design is simple and intuitive, with everything just a few taps away.

I accessed the site from my iPhone and had a good look around, clicking the various tabs and links to test it out. I have to say it was extremely responsive, the site worked seamlessly and when I clicked on a game it loaded instantly. Very impressive!

Player Support and Service

If you need support or assistance while playing at 21.co.uk casino, then you can use one of the following tools:

The Help Section is fairly handy – there’s designated areas such as Payments, Bonuses, Account and also a search function to ask a specific question. I looked over a few sections to see how comprehensive it was. Although it was basic, it did provide some answers. 

However, the live chat service is where you can get personal help. I joined live chat and was initially connected to a help bot, before being quickly directed to an agent. The responses were quick and helpful and the agent was really friendly too so I had a good overall experience.

Banking and Payment Methods at 21.co.uk Casino

Although 21.co.uk doesn’t offer the biggest range of payment options, there are a few methods that would appeal to most players.

21.co.uk Casino Payment Options

The good news for players is that quick convenient mobile payments are available, plus 21.co.uk is a PayPal casino too.

  • Apple Pay
  • Visa Debit
  • Visa Electron
  • PayPal
  • Bank Transfer

The minimum deposit for all methods is £10 which is standard. But in my opinion, some extra options should be added such as Google Pay, Skrill, and Neteller. 

21.co.uk Casino Withdrawal Speeds

Unlike the UK’s top fast withdrawal casinos, 21.co.uk doesn’t offer instant payments. Instead, the website states all payments can take up to 3 business days. This isn’t ideal if you want your winnings straight away. However, this should be the longest it takes and many payments do arrive within 24 – 48 hours.

How to Sign Up and Deposit at 21.co.uk Casino

During my 21.co.uk review, I registered at the site and found the sign-up process quick and straightforward. Here’s a step-by-step guide to help you get started:

  • Click the casino link on this page, then select ‘Sign Up’;
  • Enter your email address and create a password;
  • Fill in your name, date of birth, mobile number, and address;
  • Agree to the Terms and Conditions, confirm that you’re 18, and select your marketing preferences;
  • Complete sign-up;
  • Verify your account;
  • Make your first payment of at least £10 – making sure you’ve opted into the welcome offer first.
