“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 below is drawn from the public UKGC register, checked in July 2026.
What Are Casino Sister Sites?
Sister sites are separate casino brands that are owned and operated by the same company, and usually run on the same underlying software platform. Think of them as different shopfronts for the same business. 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 rather than owning them. The two ideas overlap and often get muddled, so we’ve split the detailed explanation of white-label arrangements into its own guide. 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 are 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.
| Operator | UKGC account # | Flagship brands | Approx. size |
|---|---|---|---|
| Skill On Net Limited | 39326 | PlayOJO, Slingo.com, PlayToro, Swift Casino | 52 trading names |
| L & L Europe Limited | 38758 | Pub Casino, All British, Fun, Yeti, Hyper, QuickBet | ~10 UK skins (brands registered as domain names) |
| Gamesys Operations (Bally’s Corp) | 38905 | Jackpotjoy, Virgin Games, Bally, Rainbow Riches, Monopoly Casino | bingo-led; brands registered as domain names |
| ProgressPlay Limited | 39335 | BetMaze and a wide skin network | large (distinct from L&L) |
| Jumpman Gaming | 39175 | 60+ bingo/casino skins (industry-reported) | largest by brand count |
| Petfre (Gibraltar) Limited (Betfred) | 39544 | Betfred | thin (single domain) |
| Entain (LC International Limited) | 54743 | Ladbrokes, Coral, Foxy Bingo, Gala | 13 sites on one remote licence |
| Flutter Entertainment | no single licence | Paddy Power, Betfair, Sky Bet/Vegas/Casino, Tombola | subsidiaries hold their own |
| evoke plc (ex-888) | 39028 / WHG (Int’l) | 888casino (888 UK Limited), William Hill (WHG International Limited) | rebranded 2024 |
| White Hat Gaming Limited | 52894 | Casimba, Dream Vegas, Grand Ivy, Jackpot Village | ~30 white-label skins |
| Rank Interactive (Gibraltar) Ltd | 57924 | Grosvenor, Mecca Bingo, The Vic, Magical Vegas | ~12 brands |
| LeoVegas Gaming PLC (MGM) | 39198 | LeoVegas, BetMGM UK, BetUK, Pink Casino | 6 UK brands |
| BV Gaming Limited (BetVictor) | 39576 | BetVictor, Parimatch, talkSPORT BET, Smooth Spins | 6+ media-partner brands |
| Videoslots Limited | 39380 | Videoslots, Mr Vegas, Mega Riches | 3 brands |
| Solaya Group Ltd (ex-Dazzletag / Gogame) | 39358 | Casushi, Fruit Kings, Peachy Games | 3-4 brands |
| Dribble Media Limited | 42647 | Midnite | single brand |
Numbers change as brands launch and close, so treat this as a July 2026 snapshot rather than a permanent list. Below we break down eleven of these networks brand by brand, and every casino we have reviewed within them has its own dedicated sister-sites page linked in each section.
The Major Networks, Brand by Brand
Jumpman Gaming: The Mega Reel Network
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 skins while keeping its flagship brands live.
These are the Jumpman brands we have mapped in full:
Skill On Net: PlayOJO and 51 Others
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:
White Hat Gaming: The Largest White-Label Stable
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, from the established generalists to the newest launches:
- Casimba
- Grand Ivy
- Temple Nile
- SpinYoo
- Playzee
- Slot Nite
- Skol Casino
- Casiku
- Spin Station
- Spinland
- Spin Rider
- Dream Vegas
- Jackpot Village
- Barz
- Blackjack City
L & L Europe: The Pub Casino Family
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 are distinct licensees and we treat them separately.
The full L & L Europe family we have reviewed:
Rank Group: Grosvenor, Mecca and the Stride Brands
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 have reviewed:
Entain: Ladbrokes, Coral and the Gala Family
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:
Gamesys: The Bally’s IP Brands
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:
LeoVegas Group: The MGM-Owned Network
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 have reviewed:
BV Gaming: The BetVictor Media Brands
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:
Videoslots Limited: Videoslots, Mr Vegas and Mega Riches
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:
Solaya Group: The Ex-Gogame Cluster
The casinos marketed through Gogame Partners run on the licence historically held by Dazzletag Entertainment Limited, UKGC account 39358, with the group restructuring under the Solaya Group name in 2026. The open UK brands share a near-identical wager-free free-spins welcome on the same featured slot, differing mainly in format breadth and payment speed: Peachy Games leads on bingo and Slingo, Fruit Kings on withdrawal speed and apps, and Casushi on its quirky brand identity. PlaySunny was part of this family but stopped accepting UK players when it relaunched in 2026, so we cover it as history only.
The open Solaya Group brands we have reviewed:
Betfred: A Network of One
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 isn’t a skin network: it’s 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: Deliberately Standalone
Midnite, operated by Dribble Media Limited (UKGC 42647, Companies House 09555672, incorporated April 2015), has no sister sites at all. 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:
- Scroll to the foot of the casino’s website. UK-licensed sites must display the operating company’s legal name and licence details in the footer.
- Go to the Gambling Commission public register at gamblingcommission.gov.uk and search by that company name, for example “Skill On Net Limited” or “L & L Europe Limited”.
- Open the licensee’s record and look at the “trading names” section. Every brand that operator runs on that licence is usually listed there. Some operators (L & L Europe, Gamesys, Jumpman) show zero trading names and register their brands as “domain names” instead, so check that list too before assuming a licence is a single-brand one.
- If two casinos appear under the same account number, they are sister sites, regardless of how different the branding looks.
- Cross-check the account number against what the footer claims. A mismatch, or no UK licence at all, is a red flag worth walking away from.
This is the same method behind every licence number on this page.
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, because they’re the same operation underneath. 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 are not 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.
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 skins of a larger family.
Expert Tips
Check the Licence Number, Not the Logo
Two casinos with completely different branding can sit on the same Gambling Commission account. The licence number in the site footer, not the name or design, tells you who actually runs a casino. One licence also means one shared GAMSTOP self-exclusion across every brand on it.
Frequently Asked Questions
-
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. Prefer to understand the licensing mechanics behind all of this? Our white-label vs sister sites guide covers how these arrangements are built. 18+ only. Please gamble responsibly; support is available at GAMSTOP and BeGambleAware.org. -
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 and Solaya Group, 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.
