UK Casino Sister Sites

What Are Casino Sister Sites?

“Sister sites” is one of the most searched terms in UK online casino, and one of the most misunderstood.

If you’ve ever noticed that two casinos with completely different names share the same layout, the same welcome offer wording or the same support email, you’ve spotted a sister-site network.

On this page, we explain exactly what sister sites are, map the biggest UK networks by their Gambling Commission licence, and show you how to check for yourself who really runs any casino.

Every operator name and licence number on this page is drawn from the public UKGC register, checked in August 2026.

How Do Sister Site Casinos Work?

Sister sites are separate casino brands that are owned and operated by the same company, and usually run on the same underlying software platform.

Each has its own name, theme and website, but behind the scenes they share an operator, a technology stack and, crucially, a UK Gambling Commission licence.

This is different from a white-label casino, where a brand rents its licence and platform from a third-party provider.

If you want the mechanics of how white-label licensing works, read white-label casinos vs casino sister sites. This page focuses on the networks themselves: who owns what, and how to tell.

The simplest definition: if two casinos appear on the same operator’s Gambling Commission licence, they’re sister sites.

Everything else (matching designs, shared bonus terms, identical terms and conditions) is a clue, but the licence is the proof.

The Biggest UK Casino Networks in 2026

Below are the major operators behind UK-licensed casino brands, with their Gambling Commission account numbers where we’ve confirmed them on the public register.

“Size” is an approximate count of live UK-facing brands on the licence. One quirk to know before you use the register yourself: not every operator lists its brands the same way.

Some (like SkillOnNet) enumerate dozens of “trading names”; others (L&L Europe, Gamesys, Jumpman) register their brands as domain names instead, with zero trading names shown, so you sometimes have to check the domain-names list, not just the trading-names one.

Numbers change as brands launch and close, so treat this as a August 2026 snapshot rather than a permanent list.

The Major Networks, Brand by Brand

Below, we break down eleven of these networks brand by brand, and every UK casino we’ve reviewed within them has its own dedicated sister-sites page linked in each section.

Jumpman Gaming

Jumpman Gaming Limited holds UKGC account 39175 and runs one of the largest white-label networks in the UK, with well over a hundred casino and bingo skins on a single licence.

Every Jumpman brand is legally the same operator, sharing one platform, one payments backend and the gamified “Mega Reel” welcome mechanic that spins for a randomised free-spins prize.

Super Group, the parent of Betway, acquired Jumpman in 2022. The network has been trimming its portfolio, retiring smaller sites while keeping its flagship brands live.

These are the Jumpman brands we’ve mapped in full:

• Amazon Slots
• Wild West Wins
• The Sun Play
• Space Wins
• HeySpin
• Rainbow Spins
• Dove Slots

Skill On Net

Skill On Net Limited holds UKGC account 39326 (Casino Remote since November 2014) and lists 52 active trading names on that single licence.

Its best-known UK brand is PlayOJO, built around genuinely no-wagering bonuses, with PlayToro and Swift Casino sharing a similar ethos.

Slingo.com sits on the same licence too, which surprises people because it feels like a standalone Slingo brand.

The register throws up bigger surprises still: Genting Casino and Knightslots are both SkillOnNet trading names on this same licence, not the standalone operators their branding suggests, alongside names like SlotsMagic, Queen Vegas, MegaCasino, Spin Genie, LuckyNiki, Prime Slots, Luna Casino and EU Casino.

Our full breakdowns across the SkillOnNet roster:

• PlayOJO
• Slingo
• PlayToro
• Swift Casino

White Hat Gaming

White Hat Gaming Limited operates on UKGC account 52894 and runs around 30 UK-facing brands as white-label sites, one of the biggest multi-brand stables on the register.

The Malta company supplies the platform, licence, payments and compliance layer, and its brands share a near-identical wager-free “Bet and Get” free-spins welcome template.

Self-exclusion applies across the whole White Hat estate, so closing one brand can lock the siblings too. The newest addition, 247Bet, also trades on the same licence.

The White Hat brands we cover:

• Casimba
• Grand Ivy
• Temple Nile
• SpinYoo
• Playzee
• Slot Nite
• Skol Casino
• Casiku
• Spin Station
• Spinland
• Spin Rider
• Dream Vegas
• Jackpot Village
• Barz
• Blackjack City
• 247Bet

L&L Europe

L&L Europe Limited (UKGC 38758, Malta company C53706) runs one of the tightest, most identifiable networks in the UK: Pub Casino, All British Casino, Fun Casino, Yeti Casino, Hyper Casino and QuickBet Casino, plus Casino Casino.

The theming varies wildly across pubs, patriotism, fairgrounds, winter and motorsport, but the platform, terms and support are shared.

A common web claim conflates L&L with ProgressPlay (39335); they’re distinct licensees and we treat them separately.

The full L & L Europe family we’ve reviewed:

• Pub Casino
• Fun Casino
• All British Casino
• Hyper Casino
• Quickbet Casino
• Casino Casino
• Yeti Casino

Rank Group

Rank Interactive (Gibraltar) Limited operates UKGC account 57924, the digital licence behind The Rank Group plc, the Maidenhead-listed operator whose Grosvenor and Mecca names date to 1967 and 1961.

Rank’s 2019 acquisition of Stride Gaming folded in a cluster of digital-only brands (Magical Vegas, Lucky VIP, Rialto, Spin and Win), which is why they share the same licence as the heritage casino and bingo halls.

Every brand runs its own named loyalty currency on an identical points-to-bonus mechanic, a clear family fingerprint.

The Rank brands we’ve reviewed:

• Grosvenor
• Magical Vegas
• Mecca Bingo
• Regal Wins
• Spin and Win
• Lucky VIP
• Rialto
• The Vic

Entain

Entain plc licenses its UK online casino and bingo brands through LC International Limited, UKGC account 54743.

Formed when GVC Holdings acquired Ladbrokes Coral in 2018 and renamed itself Entain in 2020, the group runs owned brands on shared proprietary technology rather than third-party white-labels.

Ladbrokes and Coral are the sportsbook-led heritage names, Party Casino is the casino-first sibling, and Gala Spins carries the Gala bingo heritage into a spins-focused product.

Our Entain network breakdowns:

• Ladbrokes
• Coral
• Party Casino
• Gala Spins

Gamesys

Gamesys Operations Limited holds UKGC account 38905 and has been a Bally’s Corporation subsidiary since 2021.

The network pairs licensed-IP destination brands, Monopoly Casino built on the Hasbro licence and Rainbow Riches Casino built on the Barcrest slot, with the broad-appeal Virgin Games and the Vegas-heritage Bally Casino.

Each brand runs a separate account on the shared Gamesys platform, so a fresh welcome offer is available at every sibling.

The Gamesys brands we cover:

• Virgin Games
• Bally Casino
• Monopoly Casino
• Rainbow Riches Casino

LeoVegas Group

LeoVegas Gaming PLC operates UKGC account 39198 and has been wholly owned by MGM Resorts International since 2022.

The group’s six UK brands each lean on a different vertical: LeoVegas is the mobile-first flagship, BetMGM carries the Vegas entertainment branding, BetUK is sportsbook-led, Pink Casino owns the bingo depth, 21.co.uk focuses on live and table games, and Slot Boss is the pure-slots specialist.

Five of the six share the same welcome-offer slot, a sign of one shared bonus engine underneath.

The LeoVegas Group brands we’ve reviewed:

• LeoVegas
• BetMGM
• BetUK
• Pink Casino
• 21.co.uk
• Slot Boss

BV Gaming

BV Gaming Limited runs UKGC account 39576, the licence behind BetVictor, the Gibraltar-based bookmaker that traces its roots to a 1931 British betting business.

Rather than faceless skins, its siblings are media-partner brands built on the shared BetVictor platform: Parimatch brings a global sports name to the UK, talkSPORT BET ties in with talkSPORT radio, and Smooth Spins leans into bingo and Slingo with Smooth Radio branding.

Withdrawal speed and payment options genuinely differ across the four.

Our BV Gaming network pages:

• BetVictor
• Parimatch
• talkSPORT BET
• Smooth Spins

Videoslots Limited

Videoslots Limited holds UKGC account 39380 and has sat under the Immense Group holding company since late 2024.

The Malta operator’s original Videoslots brand is the only one of the three with a sportsbook and video poker; Mr Vegas is the Vegas-themed sibling that now fronts Sheffield Wednesday’s shirt; and Mega Riches is the jackpot-forward skin built around Wowpot progressive content.

All three share the same account and payments backend.

The Videoslots brands we cover:

• Videoslots
• Mr Vegas
• Mega Riches

Betfred

Betfred is the exception that proves the rule. The consumer brand runs on Petfre (Gibraltar) Limited’s licence (UKGC 39544, held since 2014), with a separate Betfred Technology Limited entity (49528) covering the software layer.

But Betfred is a single domain with sport, casino, bingo and lottery sections rather than a stable of differently-named casinos.

A secondary brand, OddsKing, has closed; its site now redirects to a decommission notice pointing former players to Betfred.

Our Betfred sister sites page explains what Betfred runs instead, and lists similar casinos.

Midnite

Midnite, operated by Dribble Media Limited (UKGC 42647, Companies House 09555672, incorporated April 2015), has no sister sites at all as an independent casino.

Multiple trackers agree it’s a single standalone brand, and that’s by design: an esports-first, single-platform strategy rather than a multi-brand network.

If you specifically want a casino that isn’t part of a larger family, Midnite is a useful contrast case.

More on why on the Midnite sister sites page.

How to Check Who Runs a Casino

You don’t have to take anyone’s word for it, ours included.

The Gambling Commission’s public register lets you confirm exactly who operates any UK-licensed casino in a couple of minutes. Here’s the process we use for every brand on this site:

Pros and Cons of UK Sister Site Casinos

Now, like anything in life, there are some pros and (small) cons to playing at sister site casinos as a UK player.

It really all comes down to you as an individual and what your preferences are; there are no right or wrong answers.

Still, we believe it’s worth knowing what you’re getting into before you sign up to any UK sister casino site, listed on this page or otherwise.

Why Sister Sites Matter to You as a Player

Knowing which casinos share an operator changes a few practical things.

Welcome bonuses usually don’t stack across a network

Most operators treat a welcome offer as one-per-customer across all their brands, not per brand.

Signing up to a second casino in the same family rarely earns you a second new-player bonus, because your account is recognised across the network.

If claiming fresh welcome offers matters to you, moving between different operators is what actually unlocks them, not different brands on the same licence.

Terms, support and withdrawal experience tend to be shared.

If you had a poor experience with one brand in a network (slow withdrawals, restrictive bonus terms), you’ll often find the same policies at its siblings.

Equally, if you trust one, its siblings are a reasonable place to look next.

GAMSTOP and self-exclusion apply across the licence.

Every UK-licensed operator must integrate with GAMSTOP, and self-exclusion through GAMSTOP covers all UK-licensed brands.

Separately, if you self-exclude directly with one brand, that exclusion applies across the operator’s brands on the same licence too.

We want to be completely clear: sister sites aren’t a way to get around GAMSTOP or a self-exclusion. If you’ve excluded yourself, these brands are closed to you by design, and that protection is working exactly as intended.

UK Casino Sister Site FAQs

• What does “sister site” mean in online casinos?

  It means two or more separate casino brands owned by the same operator, usually on the same software platform and the same UK Gambling Commission licence. Different names and themes, same company behind them.
• How do I find a casino’s sister sites?

  Find the operating company in the casino’s website footer, search that name on the Gambling Commission public register, and read the “trading names” on its record. Every brand listed under the same account number is a sister site.
• Can I claim a welcome bonus at each sister site?

  Usually not. Most operators apply their welcome offer once per customer across every brand on the network, so a second sign-up within the same family typically won’t trigger a fresh bonus. New customers only, 18+, T&Cs apply.
• Does self-exclusion cover sister sites?

  Yes. GAMSTOP self-exclusion covers all UK-licensed brands, and excluding directly with one brand also applies across the operator’s other brands on the same licence. Sister sites are never a way around self-exclusion.
• Are sister sites safe to play at?

  A sister site is exactly as safe as any other UK-licensed casino: the same Gambling Commission licence, rules and player protections apply. Always confirm the brand holds a current UK licence on the public register before depositing.
• Which UK operator has the most sister sites?

  By brand count, Jumpman Gaming (UKGC account 39175) is widely cited as the largest with 60+ bingo and casino skins, while Skill On Net lists 52 trading names on account 39326. Numbers shift as brands launch and close.
• How many casino networks does this page map?

  This page maps eleven major UK casino networks brand by brand: Jumpman Gaming, Skill On Net, White Hat Gaming, L&L Europe, Rank Group, Entain, Gamesys, LeoVegas Group, BV Gaming, Videoslots, plus standalone brands like Betfred and Midnite. Every casino we have reviewed within a network has its own dedicated sister-sites page, all cross-checked against the Gambling Commission public register.

Why Play at Sister Site Casinos?

Casino sister sites prove that, sometimes, sticking with the family isn’t such a bad idea.

While many sister sites share the same look and feel, they also offer players a sense of familiarity.

That means more choice, access to different welcome offers, consistent security standards, and, perhaps most importantly, the confidence of playing with an operator you already know and trust.

Understanding how casino sister sites work – and knowing which UK sister sites are worth your time – can help you make smarter, safer decisions when choosing where to play.

If you’re looking for trusted operators backed by established casino groups, the list of the best UK casino sister sites on this page is the perfect place to start.

But if, having read all this, you’d rather play somewhere that isn’t part of a big network at all, we keep a separate list of independent casinos: single-brand operators that aren’t part of a big family network.

Remember, whichever site you choose, gambling should always be enjoyable and within your means. Set limits, stick to your budget, and never chase your losses.
