21.co.uk Casino Sister Sites & Review

21.co.uk is a Leo Vegas casino focusing on its live dealer offerings. As part of the LV Gaming group, the 21 Casino sister sites include Pink Casino, Slot Boss, and Leo Vegas.

What sets 21.co.uk Casino apart from the competition is its unique welcome bonus. Aside from the 100% match bonus of up to £50, all new players also receive £6 free in live casino chips.

21.co.uk Review for 2024

21.co.uk homepage

21.co.uk is an online casino operated by LeoVegas Gaming PLC that holds a valid license from the UK Gambling Commission (#39198). The website utilises a black and blue theme, and it specialises in providing customers with a live casino-focused experience rather than just ordinary casino gaming or sports betting. You can learn more about the site with our 21.co.uk Casino review right here.

21 UK Welcome Offer

Anyone who registers at 21.co.uk can claim a 100% deposit match bonus of up to £50 plus £6 in live casino chips. According to the terms and conditions, you’ll need to make a deposit to claim the bonus, and the £50 bonus must be wagered on live casino games before the £6 bonus is credited. Finally, the £6 bonus can only be used on selected Evolution games within three days.

Unfortunately, 21.co.uk does not offer many additional promotions. At the time of writing, you can claim a £5 bonus on your next deposit to use on the website’s Game Of The Week. Terms and conditions state that you must deposit £40 or more and wager the bonus three times on slot games within three days of claiming it. That’s it, there are no other promotions available at 21.co.uk and that includes a loyalty scheme or VIP club.

Is There A 21.co.uk No Deposit Bonus?

No. As we mentioned above, aside from the welcome offer and £5 deposit bonus, there are no other promotions available at 21.co.uk, and that includes a free spins no deposit bonus. All promotions available at the site require a deposit to claim, but if this ever changes, we’ll make sure to update our review – please check back!

Casino Games And Software Providers

One of the reasons 21.co.uk remains so popular is its catalogue of casino games. Since the site has a strong focus on live casino content, you can enjoy live variations of classic table games like Roulette, Blackjack, and more, and live game shows too, all of which have been provided by On Air Entertainment and Evolution.

Outside of live casino content, 21.co.uk provides you with a range of other content, including video slots, table games, jackpots, and instant win content. The games here have been provided by big-name studios like NetEnt, Barcrest, Relax Gaming, Eyecon, Play’n GO, Blueprint Gaming, Pragmatic Play, Red Tiger Gaming, and numerous others too.

All of the casino games available at 21.co.uk utilise a wide range of themes and gameplay mechanics, which means they’re perfectly suited for new, casual, and experienced players, as well as high rollers too.

21.co.uk Slots You Should Play

Since 21.co.uk is home to a plethora of casino games, it can be somewhat difficult to work out which games are worth playing. That’s why we’ve decided to compile a list of four video slots that we think are all worth playing, regardless of your skill and experience. Check out our recommendations below.

21.co.uk slots

One 21.co.uk video slot that is worth playing is Starburst by NetEnt, which uses a 5×3 grid layout with 10 paylines and has an RTP (Return to player rate) of 96.90%. Symbols in the slot include bars, sevens, and gems, and it has special features that include expanding wild symbols that can help make more wins, making it perfect for slot newcomers.

Another 21.co.uk slot is Reactoonz by Play’n GO, which uses a 7×7 grid layout with an RTP of 94.51%. Instead of using ordinary paylines, the slot comes with a cluster pays mechanic, where you must land clusters of identical symbols to create winning combinations. Feature-wise, the game comes with wild symbols, randomly-triggered bonus mechanics, destroyable symbols, quantum features, and so much more. Experienced players and high rollers will likely enjoy this slot more.

Lollipop is another 21.co.uk slot. Developed by AvatarUX for Yggdrasil, the game uses a 5×3 grid layout with between 486 and 33,614 paylines. Its symbols include stars, hearts, burgers, cakes, teddy bears, orange slices, and other candies. Special features in the game include multipliers, re-spins, a free spins mode, upgradable symbols, a gambling mechanic to further boost wins, and a PopWins mechanic, where winning symbols pop and are replaced by two symbols to increase the game’s reel height. All of these unique features mean the game is best suited for high rollers.

Our final pick for a 21.co.uk slot is Jammin’ Jars. From developer Push Gaming, the slot uses an 8×8 grid layout without paylines, opting instead to use a cluster pays mechanic. Symbols in the game include fruits like oranges, blueberries, strawberries, apples, grapes, and more. For special features, the game comes with wild symbols, a free spins mode, giant symbols, and more. These fun mechanics all help make the game perfect for casual players.

21.co.uk Sports Betting

Alongside providing you with a range of casino games, 21.co.uk also runs a sportsbook through which you can wager on numerous sports games and events, including baseball, chess, football, eSports, golf, motorsports, table tennis, snooker, rugby, rowing, netball, boxing, and more. You can also wager on non-sports events, like politics, television shows, and competitions too.

Everything available at the 21.co.uk sportsbook can be wagered on as normal or in-play, where you place bets on events and games as they happen rather than before. Unfortunately, like other LeoVegas-operated sportsbooks, there are no virtual sports opportunities, which is somewhat disappointing. However, there’s still plenty for you to enjoy at 21.co.uk, casino and sports betting included.

Deposits And Withdrawals

21.co.uk doesn’t accept many payment methods. At the time of writing, you can only make deposits with PayPal, bank transfers, and VISA and MasterCard debit cards. All methods can be used to make instant deposits at no extra charge, which means you’re free to immediately start playing your favourite casino games.

When it comes to withdrawals, all cashouts must be done back to the same method that was used to deposit. Thankfully, all payment options can be used for withdrawals, and all payments are processed and paid within around five working days. While 21.co.uk isn’t the fastest at withdrawing your funds, it’s still relatively quick, and all of this is done with no fees!

21.co.uk Sister Sites


21.co.uk has several sister sites, with the main sister brand being LeoVegas Casino, a lion-themed website that acts as both an online casino and sportsbook. The website offers you a choice between three welcome offers (Casino, live casino, and sports betting), and it runs several other promotions for the casino and sportsbook, including opportunities to win big jackpots as well as a free spins no deposit bonus!

In terms of content, you can enjoy popular casino games from developers that include Pragmatic Play, Play’n GO, NetEnt, Red Tiger Gaming, Evolution, Games Global (Formerly Microgaming), Big Time Gaming, Yggdrasil, and numerous other studios too. There’s also sports betting on most usual sports both as regular betting and in-play, giving you complete freedom. All of this is available both in-browser on all devices as well as through the dedicated LeoVegas mobile app.

Pink Casino

Pink Casino is another 21.co.uk sister site. The neon-lit casino offers new users 50 free spins with a deposit match bonus of up to £150, and regular promotions include chances to win large jackpot prizes, deposit bonuses, and more. When it comes to gambling content, you can enjoy lots of games like video slots, jackpots, table games, and live casino content too, all of which can be enjoyed across all devices.

If that isn’t enough to interest you, Pink Casino also runs 90-ball, 80-ball, 75-ball, and 30-ball bingo rooms. The rooms all utilise unique themes and have varying gameplay mechanics. They also come with chat rooms so you can talk with your fellow players, all while trying to win the different cash prizes on offer. Like the casino games, the bingo rooms available at Pink Casino are mobile-friendly, allowing you to choose how to play. You can learn more about bingo with our guide here.

Slot Boss

Another 21.co.uk sister site is Slot Boss, a website that uses the same design and layout as Pink Casino but with a blue colour scheme. Like its sister sites, Slot Boss offers a generous welcome package, some other bonuses, and lots of casino games to choose from. It also accepts a small selection of payment methods, which you’ll have to use to access and play at the online casino. Accepted payments right now include PayPal, bank transfers, and VISA and MasterCard debit cards too.

All of the above deposit methods can be used to make instant payments, and all options can be used for withdrawals that are completed within a few business days. These payments aren’t as fast as some casinos, but they’re still great and allow you to receive your funds quickly without those dreaded long wait times.

Bet UK

Bet UK is the final 21.co.uk sister site available. The website is an online casino with sports betting, and it offers the same content available with its sister sites, including casino games. There’s also sports betting across multiple types of sports and events, and the website provides you with promotions for both the casino and sportsbook, with lots to keep you busy.

With so much content available, you may run into an issue and need some help. Well, Bet UK runs an extensive help centre, and it allows you to contact the Bet UK support team directly through live chat or email. All of this can be accessed on all devices in-browser or in apps on smartphones and tablets, and the support services will ensure you’re kept safe and have someone to speak with should you run into any issues while playing.

How to Contact 21.co.uk

Like with all of our reviews, we like to check what customer support is available for use at 21.co.uk. First of all, the online casino runs a help centre split into several categories; Accounts, Payments, Safer Gambling, Game Rules, Source Of Income, Live Casino, Sports, Casino, and GDPR, Security, and Other Questions. If you run into an issue, you should hopefully find some guidance within the help centre.

Email And 21.co.uk Live Chat

If the help centre wasn’t enough, you can always contact the 21.co.uk customer support team by emailing them at [email protected] or by using the live chat service, which can be accessed by clicking the pop-up bubble in the corner of the screen after clicking the ‘Help’ button on the main menu in-browser. If you’re playing in the app, you can access the live chat by hitting the ‘Support’ button on the sticky menu – there is no way to access live chat in the live casino app right now.

Is There A 21.co.uk App?

Yep, there are actually two 21.co.uk apps available to download; a traditional casino app and a live casino-focused app. The basic casino app uses the black and blue colour scheme the brand is known for, and it welcomes you with a large splash screen showcasing the website’s welcome offer. Under the splash screen is a selection of casino games, and along the bottom of the screen is a sticky menu that allows you to access the site’s casino games, jackpots, sportsbook, and customer support. A collapsible menu accessed via a button at the top of the screen allows you to search for content.

Although the live casino app uses the same colour scheme, everything else is different. First and foremost, you can only play live casino games through this app, while the basic app allows you to play all content. What’s more, the app opens by showing you a selection of games you can play, and there’s a search function and a scrollable menu along the top of the screen that allows you to filter out the games available; Blackjack, Game Shows, Roulette, Poker, and Baccarat.

Finally, we have to note that you can also access 21.co.uk in-browser on mobile. The site works just like the basic casino app, using the same colour scheme and layout, but with no sticky menu at the bottom of the screen. Instead, the mobile in-browser website has a collapsible menu that allows you to access all aspects of the casino.

We encountered no issues while using the 21.co.uk mobile apps, and both provide you with access to the site’s selection of casino games. However, we believe that the basic casino app is best to use as it offers all types of content rather than restricting you to just one. The in-browser mobile site is also a great way of accessing the casino and playing your favourite games, and it’s great that 21.co.uk provides you with so much freedom!

Playing At 21.co.uk On Desktop

Finally, 21.co.uk also works on all desktop computers and laptops in-browser, and it functions and looks just like the mobile in-browser website. There are no major differences between playing in-browser on mobile or computers, and we found the desktop in-browser site to be fast and issue free when we used it.

Safer Gambling at 21 Casino

21.co.uk takes its commitment to responsible gambling seriously by providing you with lots of advice on how to protect minors and block gambling ads and services. It also runs several tools you can use to limit your deposits, losses, session, and wagering over a day, week, or month-long period. The site also allows you to implement reality checks that track how long you’ve been playing, and you have options to take timed breaks and self-exclude from the website.

If the above tools and services aren’t enough, 21.co.uk has also partnered with several responsible gambling charities to provide you with professional assistance. You can find contact details and information about these organisations – GAMSTOP, GamCare, and BeGambleAware are just a few of them – over at the 21.co.uk safer gambling page.

Recent Player Feedback

Before we end a review, we like to check what other reviewers have said and what customers who joined the casino think. After a quick look, we’ve found that 21.co.uk has mostly received positive reviews, with critics enjoying the site’s design, unique welcome offer, mobile-friendliness, apps, range of casino games, sportsbook, and customer support. However, many reviewers also highlighted drawbacks such as the limitation of payment methods, the lack of table games, no sports betting welcome offer, and the absence of regular promotions and loyalty schemes.

Meanwhile, customers have highlighted their mixed experiences over the internet. Negative reviews we’ve seen have called out 21.co.uk’s rare game payouts (However, the site does have a UK license that requires fair games), lacklustre customer support, frustrating withdrawal process, long verification times, and allegedly missing deposits. However, the most positive reviews claimed to have experienced no problems playing at 21.co.uk, with most applauding the fast withdrawal times, range of casino games and video slots, fast verification process, and easy-to-navigate design. Like always, each player’s experience varies depending on multiple factors, but most reviews seemed positive.

We didn’t encounter any issues while playing at 21.co.uk on any platform. We think the site is a great online casino as it’s home to lots of gambling content – casino and sports betting – and offers a nice welcome package in addition to great customer support, lots of safer gambling help, instant deposits, fast withdrawals, and complete mobile-friendliness for freedom over how and when to play. There are, of course, some drawbacks to the website, including the lack of variety in payment methods, the absence of regular bonuses and a VIP or loyalty scheme, and more. However, we still think the site is a great place to play casino games and enjoy sports betting.
