Sister Casinos Are Owned by the Same Parent Company

One parent company owns, operates, and manages multiple casino sister sites.

Utilisation of White-Label for Rapid Deployment of Brands

Ready-to-use white-label solutions enable operators to launch multiple sister sites while keeping costs low, with the solution provider taking care of support, technology, and software.

Sister Casino Sites Rely on Common Backend Infrastructure

Backend resources, payment systems, game libraries, and support operations are often shared across sister site networks.

Each Sister Casino Boasts Independent Branding

Despite sharing the same platform, each sister site is a separate brand with a distinct theme, layout, and platform design.

Sister Casinos Conduct Operations Under the Same Gambling Licence

All sister casino sites operate under the gambling concession of the parent company and are overseen by the same regulatory authority.

How Do Sister Casino Sites Operate?

Sister casinos are online gambling platforms owned by the same group or company but operating under different names. As part of a family of brands, the network of sister casinos shares the same backend infrastructure and resources, providing players with similar terms of use and consistent gaming quality. However, the selection of games and bonuses, as well as the website layouts and features are not necessarily identical. Sister casino sites often target different audiences, demographics, and regions.

Common Ownership

Owned and operated by the same company, sister casinos use the same online gambling licence and are overseen by the same regulators. The shared ownership and management of these casinos results in consistent performance and reliability for players.

Shop

Shared Resources

Sister casinos often integrate the same payment methods, and backend systems, and work with identical casino game providers. It is not uncommon for casino sites across entire networks to rely on the same customer support personnel and share help-desk resources.

User-Add

Targeting Different Audiences

Sister casinos often target different market segments and may use diverse themes, layouts, and games to appeal to a particular demographic or player type. For instance, one casino might use marketing strategies focusing on slot game enthusiasts, while another may target live casino players.

Independent Branding

Even though they are operated by the same ownership group, sister casino sites have unique branding, website design, and user interface. That independence and brand identity help gamblers recognise and choose sites that cater to their preferences.

Understanding Why Casino Operators Launch Sister Casinos

Casino operators launch sister casinos to attract new players and increase existing customer retention. This is not surprising considering the average revenue per user is expected to reach $327.10 in 2025. Sister casinos exist because they help companies achieve:

  • Market segmentation by targeting different types of players (high rollers, budget players, slot game enthusiasts, live casino gamblers, etc.)
  • Brand diversification to mitigate risks, meaning if one brand doesn’t perform as planned, its sister sites will still generate revenue.
  • Efficiency of operations, as sister casinos share payment processors and help-desk resources, and are also powered by the same software.

The incentives for casino operators to launch sister casinos are evident. However, since casinos create sister casino ecosystems to be more relevant to players, it is not surprising that the advantages are often mutual.

Gamblers exploring casinos within the same sister site ecosystem benefit from its familiarity, consistency, and functionality, particularly when it comes to efficient payment gateways, customer support systems, and terms of use.

On the other hand, the diverse gaming options, tailored bonuses, and personalised user interfaces provide players with a variety of experiences that align with their unique needs.

How Licensing Works for Sister Casino Groups

Most sister sites operate under a single licence. The casino operator obtains the gambling concession from regulatory authorities, such as the Curacao eGaming, the Malta Gaming Authority, or Isle of Man.

That permit applies to all sister sites owned by that particular casino operator, streamlining the licensing process and ensuring compliance of the entire sister site ecosystem. A licence from a stringent regulator is a guarantee of:

Panda

Secure gambling: Casino operators must utilise advanced encryption technology and integrate trusted payment methods to obtain a licence.

Panda

Fair casino games: Licensing requirements stipulate that games must be independently audited by agencies like GLI, eCOGRA, and iTech Labs.

Panda

Dispute resolution: Mechanisms that help players resolve problems or report issues stemming from the casino not complying with the licensing requirements.

Panda

Transparency: Casinos are required to disclose all terms of service and ownership information to obtain a gambling concession.

It is evident that centralised regulation benefits players, as sister casino sites are able to facilitate a safe gaming environment, regardless of the casino brand a gambler chooses.

The Role of White-Label Providers in Casino Operations

Launching a casino business in the competitive iGaming industry is a challenging task. Operators are always looking to lower the barriers and shorten the process, while keeping expenses under control. That is not always possible when building casino platforms from scratch. However, the process is much more straightforward with specialised white-label casino solutions.

What Are White-Label and Turnkey Solutions for Casinos?

The go-to option for operators looking for streamlined industry entry with scalable casino options, white-label solutions are ready-made gambling platforms, where the white-label provider handles licensing and backend operations. Turnkey solutions, on the other hand, are ready-to-launch platforms where the operator, usually an independent casino, has complete control over operations, licensing, and customisation. Unlike white-label solutions, turnkey online casino providers don’t share the revenue with the platform provider.

How White-Label Solutions Support Sister Casinos

Because white-label solutions are fully functional online casino platforms, they aid operators in lowering costs, enabling time-efficient industry entry. Moreover, white-label providers help with the integration of payment systems, handle technical support, and take care of licensing, meaning multiple sister brands can be launched in a short period of time. Lastly, even though white-label platforms are functional and ready-made solutions, they are fully customisable. So, they can be tailored to fit individual brand needs. That is crucial for sister casinos that rely on unique branding to attract players.

Check the Parent Company Behind Sister Casinos

Expert Tip: Check the bonus terms across sister sites before signing up. While sister casinos are often under the same parent company, their bonuses, wagering requirements, and promotions can vary significantly. Compare offers and fine print, such as game contribution rates and maximum cashout limits, to ensure you’re getting the best value for your deposit. You might find that one sister site offers more favorable terms for the same type of bonus.

How Sister Casinos Build Their Brand and Influence Players

The concept of casino sister sites is one that combines a shared infrastructure and resources with an independent identity. So, even though online casinos are operated by the same entity, they use a lot of strategic marketing to appear as unique gambling platforms. In doing so, they manage to attract diverse audiences, while leveraging their behind-the-scenes shared resources and infrastructure. Here’s how parent companies achieve this:

Panda

Personalised themes and layouts: Most sister sites have unique designs, themes, and layouts. For instance, the same company may own a VIP online casino boasting a posh and glamorous theme catering to big-money players and a bright and playful fruit-themed sister site for casual gamblers.

Panda

Tailored game libraries: Even though casino sister sites tend to work with the same software provider, the focus on each platform may be different. For example, a sister site geared towards live casino games may feature Evolution Gaming live casino titles more prominently than Play’n GO and Hacksaw Gaming slots.

Panda

Unique bonuses: The best casino sister sites are successful at creating enticing bonuses. Even though promotions may seem similar across all sister sites, they are often unique. A slot-oriented casino, for example, might have a welcome bonus focusing on free spins, while a live dealer gambling site may offer a match deposit bonus to spend on live tables.

Panda

Localised marketing: Casinos that are part of the same sister network may target different regions. When that’s the case, the parent company localises marketing efforts, offering local language support, facilitating payments made in the local currency, as well as offering country-specific promotions.

Panda

Strategically targeting specific audiences: Instead of overloading one casino site to the point it loses its identity, parent companies often diversify their offering across multiple sister sites, thus targeting different market segments i.e. high rollers, casual players, crypto gambling enthusiasts, progressive jackpot gamblers, etc.

As parent companies build sister casinos to have their own distinct identities and offerings, they also succeed in keeping different types of players engaged. Despite sharing the same backend infrastructure and resources, sister sites are quite versatile. As a result, players with different preferences can enjoy exploring multiple sites and feel the perks of diverse gambling options. Moreover, they can do that within the same functional and secure environment they know and recognize.

STEP 1

Check for Similar Terms and Conditions

Go through the terms and conditions and look for identical wording and phrases, as well as stipulations that cover the same rules, such as bonus requirements, responsible gambling policies, and deposit and withdrawal limits. You might also want to explore the About Us section of each casino. Look for references to the parent company and compare if it is the same one for the gambling sites you are analysing.

STEP 2

Assess the Similarity of Functionalities and Features

Similar interfaces, account systems and payment gateways are often indicative of the same backend infrastructure. So, evaluate if the website layouts share similar design elements and determine if different processes, for instance, contacting support, are consistent between platforms. If casinos work with the same payment methods and have the same limits, that is another telltale sign they belong to the same sister network.

STEP 3

Analyse If There are Identical Casino Game Providers

If a casino features games from the same providers, such as NetEnt or Microgaming, and has almost identical game libraries with identical or similar layouts, that can be a sign of a shared relationship. Another indicator would be the presence of proprietary games available only across a particular sister network. This shared relationship often means that the casinos are part of the same parent company or operate under a common white-label platform.

STEP 4

Learn More about the Gambling Licence

Casino sister sites operated by the same company share the same gambling licence. So, if you find out the licence number under which a casino is allowed to operate and notice it is the same for multiple casino sites, that will tell you about a shared association. Alternatively, you can go to the official website of the licensing regulator. Once there, find the licence register and see if multiple sites operate under the same concession.
