What Are Sister Casinos?

Sister Casinos in One Paragraph

A casino brand is a name, a design and a set of promotions. The business behind it is a company that holds a gambling licence, takes your money and pays you out. One company can run many brands under one licence, and those brands are sister sites. Entain's online business, LC International Limited, runs Ladbrokes, Coral, Gala Casino, Foxy Bingo, PartyCasino, bwin and others under a single UK Gambling Commission account (7 October 2026). In Curaçao, GTW B.V. runs Donbet, MyStake and Jurassino under one licence.

Three Ways Casinos Can Look Related

Same licence holder: sister sites

This is the only link that makes a sister. One company holds the licence and runs several brands. On 7 October 2026 the UK Gambling Commission's register showed LC International Limited with 16 trading names and 15 domains. Curaçao's certificates for donbet.com and mystake.com named one company and one licence. A casino's own footer or terms can show it too.

Same owner: a wider group

Different licence holders can share one parent. Entain runs its online brands through LC International Limited and its betting shops through Ladbrokes Betting & Gaming Limited. We count these as one group, not as sisters: a different company answers for each licence.

Same platform: look-alikes only

A platform company rents out site software, a game lobby and a cashier to brands from different operators, so their sites can look almost alike. We never count a shared platform as a sister link.

What Sister Sites Usually Share

• Terms and rules. Brands under one licence tend to use the same general terms. Ladbrokes' and Coral's UK terms use the same clause numbers, down to clause 12.4 on self-exclusion (7 October 2026).
• Account checks. Some decisions follow you across a family. Ladbrokes says the loss limits and deposit caps it places on an account "may apply across all Entain companies and brands" (7 October 2026).
• Payments. Rolletto, Velobet, Zizobet and Cosmobet, all Santeda International B.V. brands, cap standard withdrawals at €7,500 a week and €15,000 a month, but set minimums of €10 or €20 (9 October 2026).
• Games. Sister sites often use the same studios, but their lobbies differ. All six Ladbrokes-family brands we compared named Playtech (7 October 2026), yet each Santeda brand showed a different lobby count (8–9 October 2026).

What Usually Differs Between Sister Sites

Brands target different players, so the visible parts change: the name and design, the welcome offer, the loyalty scheme and the product mix. At Entain, Foxy Bingo and Gala Bingo lead with bingo, Ladbrokes and Coral with sports betting, and PartyCasino with casino games.

Accounts usually stay separate too. Ladbrokes' and Coral's UK terms permit "only one Account per Brand", and we found no clause sharing a wallet between them, so you register at each. Yet a help-centre note (7 October 2026) says no new account is allowed across brands on one licence; our Ladbrokes sister sites guide sets out both.

Why a Casino's Family Matters to You

• Bonuses. Some groups limit you to one welcome offer across several of their brands; others decide brand by brand. Gala Bingo's welcome terms rule out a second welcome at any other Gala brand (7 October 2026).
• Restrictions travel. A limit the operator places on you, a verification request or a closed account at one brand can reach your accounts at its sisters. Limits you set yourself may not: Entain says they are "not shared across other Entain Group accounts" (7 October 2026).
• Self-exclusion may not. At Entain's UK brands, self-exclusion applies to one brand unless you ask for all of them. Our guide to self-exclusion and sister sites explains the options.
• Track record. Regulators act against the licence holder, so their findings bear on every brand it runs. Entain's £14 million settlement in 2022 was for failures at LC International Limited, then running 13 websites. Complaint records are kept brand by brand, so check each one.

Casinos That Look Related but Aren't

Many brands rent the same site software: the platform behind Donbet and MyStake listed 117 brands in its directory on 6 October 2026, which says nothing about ownership. Game studios, payment processors and even bonus structures are shared industry-wide.

Families also change. In February 2026 trade press reported that Donbet and MyStake had moved to GTW B.V. from Santeda International B.V. The certificates now name GTW B.V. for donbet.com and mystake.com (7 October 2026), and Santeda for its five brands, Rolletto among them (9 October 2026). Press reports link the two companies, but on their current licences they are separate families. That's why every SisterSpy page records its evidence and the date we checked it.

How to Find a Casino's Sister Sites

1. Scroll to the casino's footer and note the company name and licence number.
2. Look the company up with the regulator: our guide on how to check who owns a casino walks through it.
3. Or start from our sister sites A–Z, where each page lists the family and the evidence for every link.

Whichever casino you choose, set a deposit limit before you play and only gamble with money you can afford to lose.
