21 Casino Sister Sites 2026 ⭐️ Find the TOP 3 here!

You have played at 21 Casino for some time now (possibly a few rounds of live blackjack with your cup of tea, or a handful of spins at the weekend) and have noticed that the lobby has started to look quite repetitive. So you try a second casino, and on opening it you see the same jackpot banner, very similar game tiles and an account area laid out almost identically to the first. This is not just your imagination, and it's worth knowing the reasons before you sign up at another site.

21 Casino (which trades as 21.co.uk) is one of several brands run by the same licensed company, so you will find other brands operating under the same licence. Some are primarily focused on sports betting, some are largely slots-focused and some may appeal to you more than 21 does. Others will feel like 21 Casino in a different colour scheme.

This guide to 21 Casino sister sites gives you the name of the company that runs 21 Casino, a list of the brands on the same licence and what to consider when comparing them before you hand over your personal details. The licensing facts come from the UK Gambling Commission public register, checked on 26 October 2026, so you can repeat the check yourself within a couple of minutes.

Kayleigh "Kaz" Bramley has been comparing UK bingo and casino brands since 2013, keeping a notes app of payout times and verification snags. Her practical checks — not star ratings alone — shape the comparisons below.

Who Runs 21 Casino? The Operator Behind 21.co.uk

21 Casino is run by LeoVegas Gaming PLC, which holds UKGC account number 39198. The UK Gambling Commission register gives the company's head office as Level 7, Plaza Commercial Center, Bisazza Street, Sliema, SLM 1640, Malta, and the footer at 21.co.uk names the same company and account number. LeoVegas was acquired in 2022 by MGM Resorts International, which is why a BetMGM brand appears on the same licence.

The remote licence (039198-R-319450-029) covers casino from 1 November 2014, general betting on real events from 29 April 2016, bingo from 26 February 2018 and general betting on virtual events from 23 April 2025. When I checked, the register listed every one of those activities as active. It lists no premises and says no regulatory actions have been recorded for this business.

Why should you care? Whichever brand you select from this group, your account terms, your identity checks and any complaint all sit with the same legal company. Switching between these sites changes what you see in the lobby and the promotions; it does not change the business you are dealing with.

This comparison is for adults aged 18+. Take time to think. If gambling feels hard to control then stop now and seek help through BeGambleAware and GamCare.

21 Casino Sister Sites on the 39198 Licence

The register lists six active domains for LeoVegas Gaming PLC. Here's how they compare:

Domain on the register	Brand	What it leans towards
21.co.uk	21 Casino	Live casino, blackjack and slots
leovegas.co.uk	LeoVegas	Casino, live casino and sports betting
betmgm.co.uk	BetMGM	Sports betting and casino
betuk.com	BetUK	Sports betting, plus a casino
pinkcasino.co.uk	Pink Casino	Slots and casino games
slotboss.co.uk	Slot Boss	Slots

The register also lists a number of older domains as inactive, including bingos.co.uk, bingogodz.com, bingoloopy.com and leovegas.com, so don't rely on any list that still shows those as live sister sites.

If you came to 21 Casino for its live tables, LeoVegas is the closest relative. It has a big live casino section and also offers a sportsbook. If you like to bet on football or racing too, BetMGM and BetUK are good options, as both offer casino games alongside betting. The two brands that focus primarily on slots are Pink Casino and Slot Boss. Because all of these brands share one operator, registering and verifying should feel similar at each. The welcome offers, promotions and lobby layout, however, can vary significantly.

Why Players Look Beyond 21 Casino

People rarely leave one casino for another without cause. It's usually something specific: a favourite slot has been removed, the stakes at the live tables they prefer don't suit them, the promotions have dried up or a rival has an offer that looks better.

Knowing your own reason for switching will guide you while you look for a new online casino. If it's the game choice, chances are many of the same games are also offered at one of the sister sites, so search for the games you actually play instead of just comparing logos. If your issue is with the company as a whole (a complaint that was handled poorly, say, or account rules you dislike), switching to a sister site will do nothing to resolve it, since every brand in the table above is run by LeoVegas Gaming PLC.

My top pick right now is Sherluck. Because Sherluck is not part of the LeoVegas group, you would be dealing with an entirely different company, with its own lobby, offers and account rules, not just a different label on the same platform. Review its terms carefully before funding your account and set your limits before you deposit. Compare it using the same criteria you would use for any other casino.

Don't Confuse 21.co.uk With 21casino.com

Similar names cause plenty of confusion here. The website 21casino.com appears on the register under a completely separate company: White Hat Gaming Limited, account 52894, based in Mosta, Malta, which lists it as a white-label domain. It has no connection with LeoVegas Gaming PLC, so a comparison that mixes up the two sites will list the wrong sister sites.

So before doing a comparison of any kind, make sure you know which site you are actually using. Check your browser's address bar, look at your registration email or scroll down to the footer of the home page. This article is specifically about 21.co.uk.

It also helps to keep three different concepts apart:

• Same licensee: one company holds the Gambling Commission licence covering multiple websites, as with the six brands on account number 39198.
• Same platform: sites running on the same software can share a very similar lobby, but a shared lobby alone does not mean they are owned by the same business.
• White label: a brand uses another company's licence and platform, which is why its domain can appear under a company you have probably never heard of.

You can verify any brand yourself through the Gambling Commission's public register. The steps are as follows:

1. Scroll to the footer of the site and write down the company name and account number.
2. Search the register using the number from step 1 or the full legal name of the company.
3. Confirm the licence is active and includes the type of gambling you're interested in, such as casino.
4. Open the domain list and make sure the exact web address you're using is listed.

Bonuses, Wagering and the Golden Chips Offer

Headline welcome offer figures can change, so confirm them on the day you plan to make a first deposit. The rules underneath the headline tend to stay relatively consistent over time.

On 26 October 2026, the 21 Casino welcome promotion was aimed at live casino players. New customers had to opt in, deposit £10 or more within 7 days of registering, then wager 1× on live casino games within the same 7 days, which means £10 for a £10 deposit. They would then receive £5 in Golden Chips for eligible Playtech games, with a 3-day expiry, and game contributions vary. Each of 21 Casino's sister sites runs its own separate promotions, so don't expect the terms at one site to apply at the others.

Under UKGC rules in force since 19 January 2026, bonus wagering is capped at 10× on the bonus amount only, never on the deposit. If you see an older comparison citing wagering requirements of 35× or 50×, it is out of date. Small chip rewards can still come with conditions, so check which games qualify and how many days you have to use the award.

Before claiming a welcome bonus or any other offer, review the following:

Term	What to check
Qualifying games	Which games count towards the qualifying stake?
Reward type	Is it bonus money, free spins or chips for set games?
Time limits	How long do you have to qualify, and how long to use the reward?
Contributions	Do all games count equally towards any wagering?
Payment method	Does your chosen method qualify for the offer?
Previous accounts	Does an account at a related brand affect eligibility?

If the conditions feel like hard work for a reward you don't really want, skipping the bonus is a perfectly sensible choice.

Slots, Live Casino and the Gigantic Jackpots

21 Casino names studios such as Evolution, Pragmatic Play, NetEnt and Playtech among its game providers. Live casino action is likely to be one of the biggest draws, which fits a brand named after blackjack, and the slots area has enough variety for most players. Because LeoVegas, Pink Casino and Slot Boss share the same operator, chances are high you will see similar slot titles at each of these sites.

The site also offers access to the Gigantic Jackpots, a set of progressive jackpots. To take part, you need to stake at least 9p on an eligible game, and winners are selected at random. While a progressive jackpot can grow very quickly thanks to contributions from many players, it does not improve your chance of winning on any individual spin. Treat it as an extra rather than a reason to increase your bets.

Compare what matters during your actual sessions. Do your favourite slots appear in the selection? In the evenings, are the minimum bets at the blackjack tables acceptable to you? Which game shows are open when you sign in? Just because a table looks attractive in the lobby does not mean it is playable within your budget.

Before you play slots at 21 Casino, read through the game rules: RTP (return to player) is a theoretical average paid back over a very long run, not a prediction of what will happen in your next session. The casino can be used in a web browser and also has apps for iOS and Android. Try whichever you prefer before putting down real cash. It shouldn't take long to find the cashier, your transaction history, your deposit limits and help.

Payments, Verification and Withdrawals

The 21 Casino footer lists Visa, Mastercard and Apple Pay as payment options. Credit cards can't be used for gambling with operators licensed in Great Britain, so you will be using a debit card or a supported wallet. Check the cashier for the minimum deposit and any fees before making your first deposit.

To begin playing at 21 Casino you will have to pass age and identity checks, which may be followed by further checks on the source of your funds. Provide accurate information that matches your payment method, and only upload documents through the operator's designated secure route.

When comparing withdrawal times, remember there are three distinct stages:

1. You request to withdraw your money.
2. The casino approves your request.
3. Your bank or wallet receives the money.

A quoted withdrawal time may only cover one of these stages.

Support is available by email and live chat 24 hours a day. If something goes wrong, complain to the operator first, ask for a reference number and keep dates, amounts and screenshots. If the problem still isn't solved, you can usually take it to the operator's approved alternative dispute resolution provider after a final response or eight weeks. The Gambling Commission regulates operators, but it doesn't settle individual disputes.

Conclusion: Choosing a 21 Casino Sister Site Sensibly

The first step is to identify what you would like to change. If you want a bigger live casino under the same operator, LeoVegas is a good starting point. If you bet on sport as well as playing casino games, compare BetMGM and BetUK.

If slots are your game of choice, look at Pink Casino and Slot Boss. If you want a completely different operator, you need to look outside the 39198 licence. Once you have decided, check how the safer-gambling tools (such as deposit limits) work across the group before opening a second account. Contact support to ask whether a deposit limit or self-exclusion set at one LeoVegas brand applies to the others.

Two separate £50 limits may allow you to make two deposits of £50 each and so deposit £100 in total. It's very important to keep all your accounts within the same budget. A sister site should never be used to get around an exclusion. GAMSTOP offers wider online self-exclusion, and GamCare runs the National Gambling Helpline on 0808 8020 133.

18+ only. Please gamble responsibly and Take Time to Think.

Set money and time limits for yourself before playing, and remember: if gambling no longer feels like fun, using another account will not help.
