21.co.uk Sister Sites

What are 21.co.uk Sister Sites?

21.co.uk sister sites are other UK casinos operated and run by LeoVegas Gaming PLC, the same operator behind 21.co.uk, licensed by the UK Gambling Commission under account 39198.

A sister site, in casino terms, is a brand that shares an operator and a licence with the one you already know, which usually means shared regulatory standing, a common safer-gambling framework and a broadly similar technical backbone.

Because every brand here operates under the one UK Gambling Commission licence, the trust-and-safety layer is common to all of them.

Identity checks, deposit limits, reality reminders and self-exclusion tools follow the same UK standard whether you’re at 21.co.uk or any of its sisters.

GAMSTOP is the clearest example: it’s a UK-wide self-exclusion scheme covering every UKGC-licensed operator, so signing up blocks you across this entire group at once, along with the rest of the licensed market.

The payment options feel consistent too: debit cards, PayPal, Apple Pay and bank transfer, with no credit cards permitted under UK rules.

Worth flagging, 21.co.uk does without Skrill and Neteller, a small gap some players will notice. Withdrawal speeds aren’t identical across the family either, so each brand runs its own verification queue on top of a shared backend.

How 21.co.uk Sister Sites Compare

Below is every 21.co.uk sister site under the LeoVegas Gaming PLC licence.

Notice the welcome-offer column: five of these brands hand out free spins to new players, usually on the same headline slot, while 21.co.uk stands apart with a live-casino-chips mechanic.

21.co.uk Overview

21.co.uk keeps a distinct identity within the family: a minimalist, professional design with a genuine lean towards roulette, blackjack, baccarat and live-casino play.

It also runs a dedicated Megaways section pulling together Big Time Gaming titles and licensed Megaways slots, giving it a slightly more curated, structured feel than a sprawling slots lobby.

Where its siblings chase free-spins-led welcomes, 21.co.uk built its offer around live-casino chips, which tells you where its heart is.

Who Owns 21.co.uk?

21.co.uk is operated by LeoVegas Gaming PLC, the Malta-based company behind UK Gambling Commission account 39198. Unlike its siblings, 21.co.uk was not a native LeoVegas brand from day one.

The site was originally founded by a third party, Intellectual Property and Software Ltd, and its UK Gambling Commission licence has been active since November 2014.

LeoVegas Gaming PLC acquired the brand in 2018, making it the only casino in this six-strong family with a confirmed independent origin.

Above the operator sits LeoVegas AB of Sweden, taken private by MGM Resorts International in September 2022.

On the record side, LeoVegas Gaming PLC received a £1.32m UK Gambling Commission penalty in July 2022 for anti-money-laundering and social-responsibility failings, an operator-level event that applies across the group, 21.co.uk included.

Here’s what the register shows for LeoVegas Gaming PLC as of August 2026.

How We Verified These Casino Sites

Every sister site on this page has been cross-referenced against the UKGC’s public register to confirm who actually holds the licence.

That’s the clearest indicator of shared ownership and how sister sites are related, and it’s where we start every time.

From there, we test the platform itself: game libraries, payment methods, bonus terms, and responsible gambling tools, and score everything against the FruityMeter, our 12-category rating system built through years of real-money testing.

A shared operator doesn’t guarantee a shared quality level, and the FruityMeter score reflects each site’s individual performance rather than who owns it.

Which 21.co.uk Sister Site if You Want…

Think about what 21.co.uk is light on. Always check the current offer on each brand’s review page before signing up, as promotions and their terms can change.

• A big sportsbook next to your casino play: BetUK is the sibling to cross to, running sports plus casino side by side.
• Bingo: 21.co.uk barely competes there, so Pink Casino is the obvious pick.
• The widest possible slots and live-dealer catalogue: the LeoVegas flagship carries the deepest library in the family.
• A pure slots room with nothing else in the way: Slot Boss is the closest match in spirit, though its welcome offer asks for a higher qualifying deposit, so read the terms first.
• Vegas jackpots and the MGM name: BetMGM UK suits players drawn to that branding.

21.co.uk Sister Sites FAQs

• Who owns 21.co.uk?

  21.co.uk is operated by LeoVegas Gaming PLC under UK Gambling Commission account 39198. The brand was originally independent, founded by Intellectual Property and Software Ltd, before LeoVegas Gaming PLC acquired it in 2018. The group ultimately belongs to MGM Resorts International.
• What are 21.co.uk’s sister sites?

  21.co.uk’s UK siblings under the same licence are the LeoVegas flagship, BetMGM UK, BetUK, Pink Casino and Slot Boss. They share an operator and regulatory standing but each targets a different player, from sport and bingo to jackpots and pure slots.
• Was 21.co.uk always part of the LeoVegas group?

  No. 21.co.uk is the one brand in this family with an independent origin. It launched as its own site and was acquired by LeoVegas Gaming PLC in 2018. Its UK Gambling Commission licence has been active since November 2014, predating the acquisition.
• Do 21.co.uk sister sites share one login?

  No. There’s no shared wallet or single account across the group. Each brand needs its own registration, deposit and identity verification, so trying a sister site means creating a new account even though the same operator runs the platform behind the scenes.
• Which sister site is best for table games?

  21.co.uk is the table-and-live-casino specialist of the family, built around roulette, blackjack, baccarat and live-dealer play, with a welcome offer paid in live-casino chips. If classic casino games are your focus, it’s the most natural home in this group.

Which 21.co.uk Sister Sites Should You Try?

For anyone who already trusts 21.co.uk, its sister sites are a sensible set to explore, because the regulatory standing and safer-gambling protections carry across the whole group.

You get one operator answering to one regulator, and the freedom to choose a brand by its vertical: tables at 21.co.uk, sport at BetUK, bingo at Pink Casino, pure slots at Slot Boss, jackpots at BetMGM UK, or the broadest library at LeoVegas.

Bear in mind there’s no shared account, so each new brand means a fresh sign-up and a fresh verification, and welcome terms differ from one sibling to the next.

Compare the offers, watch for the small payment-method and withdrawal-speed differences, and set your own limits before depositing.
