    The casino is very straightforward and gives players a good gaming experience. Although there could’ve been a few more generous monthly offers and free games. – source: TrustPilot
  • 24-Dec-2020 by Michael:

  • 23-Dec-2020 by Ryan:
    I am disgusted, deposited a small amount, played, and won after which I wanted to withdraw but they blocked my account and said I breached their terms and conditions. – source: TrustPilot
  • 21-Dec-2020 by Jamie:

  • 19-Dec-2020 by Henry:
    Got a big win early on and withdrew all of it in my bank on the same day. The support was also very kind and it felt like you were talking to an actual person. Would recommend this casino to everyone. – source: WhichBingo

    The casino is a total scam! They don’t have a problem taking your money but when you want to make a withdrawal they suspend the account and mail you that you have “breached the rules” of some sort. Stay clear of this website. – source: WhichBingo
  • 05-Oct-2020 by Karina:

Besides a generous welcome bonus, there are a lot more reasons why you should take a look at this casino. Find out in our following review!

New Player Welcome Offers

The welcome offer at 21 is very attractive for new players since it’s a no deposit bonus! Once you signed up at the casino, you have 3 days to claim your free £10, which can be spent in e.g. table or slot games.
The bonus has an x50 wager requirement and the max. cash out after wagering is locked at £50.
After this free bonus, you can also claim a deposit cash reward bonus on 2 deposits of your choice within the first 7 days!

Monthly Promotions

21 has not too many monthly promotions since they appear temporarily and only last for a specific time.
In 2021 there are waiting a lot of interesting promos at this casino. If you want to know, what’s awaiting you, you can sign up for a notification service in your 21.co.uk account, which will inform you about the latest bonuses and promotions.

Pros And Cons of 21.co.uk

Talking about the pros of 21.co.uk, you have to mention the individual and good looking design of the casino, which is also available on mobile. The variety of different games, such as slots, table games, jackpots or betting, are also very positive.
On the con side, you find them, compared to other online casinos, slow working customer support, which sometimes need up to 5 days to respond. Negative as well as the fact that there are not many other promotions than welcome offer.

Featured Slots And Casino Games

Besides the very interesting betting section of 21, you can also test your luck in the live casino, which has classic games like roulette, blackjack or the, in 2021 very popular, live version of monopoly.
Fans of slot games will be happy to hear that 21.co.uk has a large selection of slots from famous providers like Play’N GO, Red Tiger or Net Entertainment. If you are looking for a jackpot game, you can play for example Dynamite Riches or Mystery Reels, which are also featured in the casino.

Deposit And Withdrawal Methods

21 has a lot of safe and secure payment methods you can choose between. You could use e.g. Debit/Credit cards like Visa, Mastercard, or PayPal.
The processing time can take as long as 2-5 working days, while transactions via PayPal will be completed within hours.
The minimum amount for both, withdrawal and deposit, is £10.

Customer Support And Licence

The casino is licenced and regulated by the Gambling Commission (GC) and is considered trustworthy.
As already mentioned, the customer support is good but could take up to 5 days to come back to you. If you have questions, you can try to find the answers in the help section of the casino!

The Verdict

21.co.uk is especially for British players a great place to play since you have a large selection of games and a generous welcome offer!

21.co.uk Sister Sites 2022

list of 21 uk sister sites 2021

Slot Boss


Slot Boss is the first entity to start off this list of ours and being created by LeoVegas in 2016, this site bosses its way in the iGaming scene with a distinctively office-look and professional website interface, with a broad range of casino games being pinned right on the homepage. Even though the casino is relatively new, they’ve managed to gain a list of both positive and negative reviews in the short time after their establishment, which means that they’ve managed to convince more players than most fresh casinos do.

A FAQ section, live chat, email, and telephone support are the four methods of contacting support on Slot Boss, and while the interface is vaguely coloured in white and blue, players can easily find their way around the site, with fitted search filters, easy-to-navigate design, and various other features

Castle Jackpot


Featuring an older-style visual and design on their site, Castle Jackpot invites casino players, especially jackpot and slot lovers, to spin their way towards imminent glories. The website is currently affiliated with the likes of Barcrest Gaming and Amaya Gaming, which are two of the most renowned providers in this list of providers on Castle Jackpot.

As the name already implies, Castle Jackpot allows iGaming players to get their hands on various high-paying jackpots, along with 300 video slots, a live chat feature, and a stream of promotions to look forward to, once players join their site. Alongside that, all players are welcomed with two different bonuses, the first of which is a 10-spin no deposit bonus for the Book of Dead slot, and the second being a £100 bonus for first depositors.



Featuring an elegant design for all those posh British players out there, UK casino rocks a sleek-designed website interface that is covered in white and blue and gives players a diverse number of casino options to select from, starting from your basic hot slot titles all the way over to live casino games and scratching cards. Although the promotions section is quite deserted, players do get a no deposit bonus of free spins, as well as a match deposit bonus on the first two payments deposited on the UK casino.

Additionally, at the bottom of the website, players can also find links to dedicated UK casino application download for both IOS and Android, available to all those compact experience loving gamers that like to take their online casinos on the go. A plethora of payment options are also provided to players, allowing them to make seamless and fast payments look easy.



This is a sportsbook sister brand with a high standard of slots and casino games. BetUK’s current signup offer is Bet £5 get £5 Free for sports punters and 10 Free Spins for any new slots players. BetUK has sponsored a few brands including Swansea FC, Darts players, MMA fighters but all of them have never really had a significant impact on making BetUK a household brand like William Hill and Ladbrokes. It seems too little, too late for such a half-hearted entry into the highly regulated sports betting market.

Leo Vegas


Leo Vegas is technically a sister site of 21.co.uk, but it is clearly on a different platform with a much more advanced and sophisticated gaming product. Leo Vegas is a global quality brand, not some cheap resin of the same product shipped out on the largely unknown and insignificant Bede Gaming platform.

Pink Casino


The colour choice on Pink Casino will have you feeling as gay as pink ink, and while the site is aimed more towards the female players of this vast iGaming community, every player is welcome to get their groove on and play a list of slots, live casino and scratch cards on this obviously-pink themed site.



In theory, seeing legs the first thing after visiting an online casino might seem like an uncomfortable experience, but the way Legs 11 portrays this unique theme on their site is impeccable. Like the previously mentioned 21.co.uk sister site, the site is loaded with a light-pink theme as well and generally attracts more female players online.



Slotto used to be a quite versatile online casino that provided players with numerous amount of casino games like slots, table games, and other instant-plays, but due to some reasons, it closed quite recently. Their URL now leads to Slot Boss, which serves as an alternative and the bringer of closing news to players that visit Slotto.

21.co.uk Sponsorships

Since its inception back in 2013, the 21.co.uk casino has been steadily growing in popularity in the gaming community and now has become a hallmark of excellence in the online casino gaming community. Its slick design entices all sorts of players into signing up at this casino, the benefits, and exceptional games that this casino provides are among the best ones in the industry. To help it rise to this level of popularity the casinos promotions and adverts played a huge part. This website combines its casino with a sportsbook, and that is why the casino is frequently sponsoring different sports events on TV channels, especially any sports event related to football. The primary TV channel the casino sponsors is ITV 4.

There is a well-maintained blog page on the casino website that is filled with all the latest news of upcoming events and promotions that will be featured at this casino. There is a lot of helpful information about gaming at the casino too from gameplay guides to popular games and promotions at the casino. News like new partnerships with various software makers is also shared in the blog section to players ought to constantly check this section of the casino or they might miss out on something important.

The 21.co.uk’s social media is very active in providing players with the latest news about the casino along with the great new promotions that will be featured at the casino in the near future. The site is active on Facebook, Twitter and YouTube which help it reach a wider audience. The casino has been live-streaming its live casino shows on YouTube quite a lot recently so viewers can check out the casino’s excellent live casino. Some of the TV commercials this casino has sponsored are as follows:

2018 – Sponsor Ad for ITV4 Nights

21.co.uk youtube ad

This short commercial is a sponsor message for ITV4 Nights. It’s a visually striking advert with some excellent camera work that makes it slick which is quite in touch with the overall aesthetic used by the casino. There isn’t a lot in this commercial and there’s only the model and the sponsor message here.

2018 – 21.co.uk sponsors A Coverage on ITV4

21.co .uk third ad

21.co.uk sponsored the airing of a football match on the ITV4 Channel. The commercial is quite in line with all the other adverts from this casino, it embodies the same colour palette with the whole commercial being tinted in a soft teal. This match was sponsored specifically by the sportsbook of the casino as the sponsored match was a match of football. Like other short ads of this site, there isn’t a lot to this ad, but the sheer level of work that went into its making must be quite hectic because this ad is quite stunning and visually aggressive just like the sports event it’s supposed to sponsor.

2019 – Short Welcome Offer Ad

21.co.uk youtube

This advert first appeared back in 2019 and showcases a tense gaming situation between a player and dealer, all eyes are set on the cards with every viewer interested in what outcome will come from this game. The game ends and a message rolls out with a commentator explaining the very interesting welcome bonus present to players at the 21.co.uk casino website. This ad features the casinos distinct and interesting theme with darkness surrounding the table covered in the casinos signature light blue or teal colour. All the important terms and conditions are also visibly mentioned on this advert to make it clear to players what’s to be expected from this welcome bonus.

Only for the UK

This casino is affiliated with the LeoVegas Gaming PLC operating out of Sliema, and as its name might suggest, this casino is exclusive to the UK gaming market and isn’t available anywhere else. 21.co.uk and many of its sister sites have made a strict decision to not operate for countries outside the UK. This is quite a big decision of not expanding which this casino made back in 2013 when it was established. Many players will miss out on this amazing casino just because it is region locked, but UK based players can rejoice and expect many great things from this casino.
