Casino Overview

The 21.co.uk casino site comes across as a sophisticated online casino with a colour pallet in distinct dark tones with white lettering, making for easy reading. Navigation is just as easy, with all the menus you need for fast browsing on the left of the screen and your account details and settings conveniently to the right of the screen.  
Finding your preferred game is easily done by selecting the Live casino, slots, jackpot, table games or instant win options. From here, you can quickly find the right game; otherwise, just head to the search function at the top left of the page to find the game you are looking for in the blink of an eye.  
The site navigation was smooth during our 21.co.uk Casino Review, with hardly any issues. Using this site on mobile presented no problem with the scaling near perfect, so you can easily use this site without the app if you want.

Casino Game Types

After doing a quick count of the online casino games available at 21.co.uk Casino, we reached a tally of 1073; that said, however, this tally does not include the scratch cards, Keno games or other instant win or arcade games that we had to search for, we`ll get into this more a bit later. Our 21.co.uk Casino review showed that there are 44 software developers providing games to this online casino, and we have to say these providers are some of the best in the industry. Here, you'll find online casino games from Authentic Gaming, Evolution Gaming, Wazdan, Red Tiger, Microgaming, and Yggdrasil, to name a few. 

As for the types of online casino games you can look forward to at the 21.co.uk Casino, players have their pick of slots, instant win games, Slingo, bingo, scratch cards, Gigantic Jackpot slots, jackpot slots(progressive jackpots), table games that include online roulette, baccarat and online blackjack and a host of live casino games which include card, dice and table games of every variation and game shows.  


Online slots make up the biggest part of the total number of games at the 21.co.uk Casino, with over 800 slots available. It's worth mentioning that if you are from within the UK, the games and online slots can only be played as real money slots, not demo games. Our 21.co.uk Casino review revealed that this online casino has an excellent collection of slots, which include, Megaways slots, Gigantic Jackpots, Jackpots, classic fruit-themed slots and video slots of every theme, colour, shape, a variety of win ways and bonus features.   

Under the slots menu, players can click into any of the sub-menus by clicking the view all button, its here that you can win real money on slots with themes such as Egyptian, fishing, Zombies, ghosts, mining, or even head to outer space for a cosmic adventure. These slots have a huge range of bonus features, some more complex such as a collection feature or levelled gameplay, and some easier to understand, such as free spins, wilds and mystery symbols.  
The 21.co.uk Casino also has two sub-menus for Gigantic Jackpots and Jackpot slots. Both of these offer progressive jackpots, but the Gigantic jackpots are tied to an exclusive 21.co.uk Casino network and take an additional £0.09 per spin to add to a pool for the Mini, Minor, Major and Mega jackpots which could be worth millions of pounds when they trigger.

While researching for this 21.co.uk Casino review, we also noted that the other jackpots here are linked to providers such as Microgaming(WowPot and Mega Moolah), Red Tiger(daily and hourly drops), IGT( A vegas-style random jackpot and progressive jackpots), Big Time Gaming(a Vegas-style random jackpot), Blueprint Gaming(Jackpot King). 

A few exciting slot examples:

  • Strom to Riches

  • Starburst 

Table Games

Moreover, you can also try your hand at a few First Person online casino games, such as Deal or No Deal and Dream Catcher, to name a few. 

Popular table games include: 

  • Vinnie Jones Blackjack 
  • 3 Card Poker 
  • European Roulette 
  • Golden Wealth Baccarat 
  • Casino Solitaire

Instant Win, Slingo, Arcade Games, and Bingo games 

For the sake of this 21.co.uk Casino review, we are bundling together all the instant win games, this includes online casino games such as Slingo, Keno, Bingo, Scratch cards, and other arcade-type games. As briefly touched on before, some of these online casino games are easy to find under the sub-menus of, for example, Slingo and Instant Win, while for some games, such as Keno and Bingo, we had to look for them in the search bar.  
Searching aside, the 21.co.uk Casino has a fantastic selection of easy-to-play instant win games where you can win real by matching three symbols or playing Slingo which is an exciting mash-up of slots and bingo.  

We explored the following Instant Win, Slingo, Arcade Games, and Bingo games: 

  • Instant Bingo 
  • Ultimate Keno 
  • Stack `Em Scratch 
  • Slingo Rainbow Riches 
  • Eggstra Cash 
  • Coins

Next, for this 21.co.uk Casino review, we tallied up all the other live casino games. There are 41 roulette, 43 blackjacks, 43 baccarat, poker and dice games, which by our standards is a pretty impressive amount of live online casino games. These live casino games are from world-renowned software providers such as Evolution Gaming, Microgaming, Pragmatic Play, Authentic Gaming and Reel Play.

Casino Bonuses and Promotions

At this point in this 21.co.uk Casino review, we had an introduction and overview of the casino and looked at the games you will find. Now it is time to look at the bonuses and promotions that you can expect at the 21.co.uk casino. The first of the 21.co.uk Casino bonuses is the Welcome offer:  

Welcome Bonus 

Just for completing the 21.co.uk Casino sign-up process, all new players can opt into the Welcome offer. This promotion includes a 100% matched deposit bonus of up to £50 with a minimum deposit amount of £10 and £6 in bonus funds useable on live games.  
This 21.co.uk Casino promotion has a couple of caveats, such as it will expire within seven days from registration. You can only cash out the bonus funds after completing the 40x playthrough requirement. The £6 in bonus funds for the live games will be split up over 3 days, with you receiving £2 per day to play with.  
As with all promotions, always read the terms and conditions before opting in to understand the requirements.  

Progressive Jackpot 

Another of the 21.co.uk Casino promotions is the jackpot, where players can win prizes worth over £13 million. To be eligible for any of the prizes, you must opt-in and play one of the games associated with the jackpot game.   
This Jackpot is progressive, meaning that a portion of every wager will contribute to the prizes on offer. The minimum bet amount is £0.10 per round and can trigger on any spin. The jackpot round consists of a colour-segmented wheel, with each segment associated with one of the prizes.

Banking Options

A  good variety of banking methods is vital to the player experience, which is why players check out this aspect early on in the casino hunting process, as it could be a deal-breaker if there aren't enough options to suit the player. The banking options should always be safe and secure, using trusted payment methods and gateways.  

Debit Cards 

The trusty debit card is one payment method that most players possess as it is used in everyday life by most people. The debit card is also the most secure as the infrastructure around it has been refined over decades.  
The 21.co.uk casino allows players to make deposits and request withdrawals using Visa, Mastercard and Maestro debit cards. The minimum deposit and withdrawal amount is £10, and the deposit should clear almost instantly. Withdrawals can take up to 5 days to clear once initiated.  


PayPal is one of the largest payment processors on the planet. Using this service, you can deposit a minimum of £10, which should, similarly to debit cards, be available in your online casino account within minutes. Withdrawals using Paypal are much faster and can be as quick as 24 hours from you making the request.  

Bank Transfer 

In addition to the other payment methods listed at the 21.co.uk casino, you can deposit and withdraw funds using a direct bank transfer. Unfortunately, they do not state how long these transactions take to show in your casino account or the withdrawal times. It is a good idea to contact the 21.co.uk Casino Customer Support team if you have any questions about bank transfers.

Game Software Providers

As you can imagine, there are a lot of software providers at this online casino. At our last count for this 21.co.uk Casino review, we found 44. These names are all well-known providers within the industry and by players, all of which boast high-quality online casino games, slots, live games and more.  
For the live casino section, players can look forward to the best live casino games from Evolution Gaming, which has been making waves in the industry since 2006, offering live-streamed game shows, roulette, blackjack and many more from upmarket studios worldwide. Pragmatic Play is not just a slot provider; they also offer an excellent range of table games and live casino games and have been around since 2015. In the same year Authentic Gaming was started, they, too, offer an extensive range of live casino and table games. 
Blueprint Gaming has been delivering jackpot slots and Megaways slots since 1957. This innovative developer delights players with multi-level gameplay, stunning graphics, and many bonus features. Another jackpot slot creator is Microgaming. Founded in 1994, they have the WowPot and Mega Moolah collections. Joining them are IGT, Red Tiger(2014) and BTG, both known for slots that are dynamic and offer various progressive jackpot drops or Vegas-style jackpots and impressive bonus features and audiovisuals. 
The other software providers are: 
NetEnt, Novamatic, NoLimit City, Play `n GO, Quickspin, Yggdrasil, Thunderkick, GTG, WMS, Scientific Games, iSoftBet, NYX, Nextgen Gaming, Elk Studios, Eyecon, Push Gaming, Bally, Barcrest, Wazdan, Lightning Box, 1x2 Gaming, Iron Dog Studios, Realistic, Games Warehouse, Relax Gaming, Open Bet, Ainsworth, Core Gaming, Inspired, Kalmaba, Plank Gaming, Golden Rock Studios, Hacksaw Gaming, Reel Play, Slingo Originals, Stakelogic, on Air Entertainment.

Safety and Trust

The 21.co.uk Casino license is issued and enforced by the UK Gambling Commission (UKGC), one of the strictest and fairest licensing agencies worldwide. Getting this license is usually a seal of approval for most casinos. Third-party companies regularly inspect the fairness of the 21.co.uk games by testing the random number generators and return to player values.   
In addition, 21.co.uk makes sure that their player's data and connections are secure when they use the site by employing top-level SSL.

Mobile Site & App

The 21.co.uk Casino website, like all other LeoVegas-owned sites, has been developed with a mobile-first approach. This means that the site has been optimised to run on almost all mobile devices, no matter the screen size. Visiting the 21.co.uk Casino is as simple as typing the name into your mobile device's browser and entering your login details. Once you have logged in, you have all the same functions as you would on a desktop computer, meaning that you can make a deposit, withdraw, chat the customer support and even claim a bonus. And because the online casino games from this casino are mobile-friendly, players can win real money while on the go. 
For our 21.co.uk Casino review, we discovered that this online has not one but two 21.co.uk Casino Apps, and while this may seem excessive, it makes perfect sense. Both apps are available for Android and iOS devices, but we used an Android device for this 21.co.uk Casino review. The first 21.co.uk Casino App we downloaded was the one that said 21.co.uk online casino in the Play Store. This app gives you all the online slots and games and sports betting options as you would on the regular website and while the second app only has live casino games. The second app appears as 21.co.uk Live Casino in the Play Store.  
Both of the 21.co.uk Casino Apps were quick and easy to install. In addition, the layouts are similar to the desktop site. Like the mobile site, we were fine logging in, contacting customer support, or navigating between pages, as the apps are very responsive. Users can win real money on all the online casino games without experiencing delays in the games' loading times. As for personal preference, we recommend the 21.co.uk online casino app as it is all-encompassing and a bit more modern looking than the live casino-only option.

Customer Support

The 21.co.uk Casino Customer Support team can be reached in various ways at this casino, showing just how seriously they take this aspect of the casino experience. Of course, you have the usual channels available, such as Live Chat at the bottom of the help page or email, but there is also a fairly decent help section available.  

  • Live Chat - Via Help section  
  • Email - support@21.co.uk  


The 21.co.uk casino experience is everything you would expect from a casino that is managed by an operator such as LeoVegas. The site is well thought out and easy to use, and most people will never have any issues. The games on offer are rather good, with a good portion of them from the top developers in the industry.  
The banking methods are a bit sparse, with debit cards, Paypal, and bank transfers the only available options, but these will do for most players. The registration process was done in only a minute or two, so you do not have to waste time filling in forms. Site security and licensing are on par with the best in the casino industry, and customer support seems to cover the basics well enough.    
So should you join? Well, the Welcome Bonus is decent enough and should be by itself reason enough to give this casino a try.

Casino Registration

Nobody wants to spend a ridiculous amount of time filling in forms when they want to join a casino. The next part is the relatively quick 21.co.uk Casino sign-up process, which requires you only to fill in one document. To get in on the action, you only need to complete two steps which are as follows: 

Step 1: 

The first step involves getting the welcome bonuses, which you can become eligible for by following the link that we provide you at the top of the page. Once you click the link, you will be taken to the registration page where you can join.  

Step 2:  

Start the registration process by providing an email address where you can be reached. Next, you need to select your username and choose a password that will be used to log you into the site.  
After that, select your gender and supply your first and last name and date of birth. Make sure these are correct, as they will be verified against the documents you must provide for KYC requirements. You can then type in your postcode or the first line of your address.  
Finally, give a contact number and then follow this by choosing your marketing preferences and agreeing to the terms and conditions, and you are ready to join.
