Important Facts to Know About Sister Casinos

Panda Image
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.

Store

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.

New

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.

Advantages and Disadvantages of Playing at Sister Sites

The blend of consistent backend infrastructures with a unique brand identity makes playing at one or more casino sister sites an engaging and diverse gambling experience. However, despite the benefits, joining sister gambling sites has some limitations. Here’s a brief overview of the pros and cons of sister site networks.

Pros Pros

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.

How Sister Casinos Share Games, Bonuses, and Payment Systems

Online casinos that operate as part of a sister network leverage shared systems and infrastructure to provide players with a consistently high-quality gambling experience. Here’s how they do it.

Games and Software Providers Across Sister Casinos

Sister casinos work with two types of software providers. First, they rely on white-label and turnkey solution providers. First, they rely on white-label and turnkey solution providers for their platforms, support, and regulatory compliance. As explained, all gambling sites within a sister ecosystem usually utilise the same platform.

The second type of software providers are game studios, such as Pragmatic Play, Relax Gaming, NetEnt, and Evolution. To provide consistent quality and a familiar and seamless user experience, parent companies often decide to feature games from the same providers across the whole network.

Please note, though, that many sister casinos focus on different types of games for a tailored gambling experience. For instance, all sister casinos within a network may work with Pragmatic Play. However, one gambling site may focus on Pragmatic Play slot games, another on live casino titles, while sister bingo sites may be oriented towards Pragmatic Play’s bingo game offering.

Checkmark

Online Casino Bonuses and How to Claim Them at Sister Casinos

Casino networks often share bonuses and promotions. While they may rely on a standardised bonus system, promotions are often different, customised to appeal to the particular type of gamblers the casino caters to.

For instance, all casino sister sites within a network may have a set number of welcome bonus offers, free spins, cash prizes, and reload bonuses. However, these bonuses may be unique for each casino sister site with specific conditions and customised incentives.

To claim these bonuses, you need to familiarise yourself with the particular bonus terms of the casino you join. Even though bonus conditions may often be similar across the sister network, they are not the same.

Checkmark

Payment Methods and Account Management

Most sister networks integrate the same payment methods used for casino deposits and withdrawals. So, if one casino sister site works with credit/debit cards, e-wallets, prepaid vouchers, and cryptocurrencies, chances are that its sister sites will feature the same banking options too. Using shared payment systems ensures familiarity and uniform transactions for players.

Some sister networks go one step further on this concept and introduce shared accounts. They allow the use of the same account across all sister sites, helping players log in using their same credentials at multiple casinos.

Having one shared account streamlines verification processes too, as players need to go through Know Your Customer (KYC) procedures only once and continue exploring different casinos within the same ecosystem without verifying their credentials over and over.

Lastly, it is also worth noting that a parent company may decide to integrate unique payment methods at different sister sites if it tries to localise payments. Working with local banking options is crucial when operating in regional markets, so it is not uncommon for casino sister sites to sometimes work with different currencies and local banking gateways.

Ensuring Fair Play Across Sister Sites

Sister casinos operate under a shared licence. That may seem insignificant but adhering to shared licensing standards can actually enhance fair play across sister sites. Here’s how:

Panda

Uniform regulatory compliance: Operating under a shared licence means that each of the casino sites in the sister network complies with the regulator’s strict stipulations.

Panda

Frequent RNG fairness evaluations: Licensed casinos undergo regular Random Number Generator fairness audits performed by independent agencies as part of their licensing requirements.

Panda

Dispute resolution mechanisms: Regulators provide players with dispute resolution channels, allowing gamblers to report problems or complaints regarding the operations of a particular sister casino.

Are Sister Sites Safe?

Sister casino sites are safe but only if they are owned and operated by reputable and licensed parent companies. A parent company that has received the regulatory approval of a renowned gambling authority is associated with secure gambling.

Moreover, obtaining and retaining a gambling licence is contingent on all sites within the sister network adhering to regulatory requirements. That is an incentive for the parent company to ensure that all of its sister casinos operate by the book.

Conclusion

Many popular online casinos are part of sister casino ecosystems that allow operators to run scalable solutions and target diverse audiences while providing players with a consistently high standard of gaming. Launched as white-label or turnkey platforms that operate under shared licences, related casinos establish themselves as the obvious choice for discerning gamblers who prioritise functionality and reliability while playing in a customised gaming environment with unique branding and gambling options created to cater to their specific preferences.

FAQ

It depends on the casino sister site you are joining. In general, both sister and independent casinos which operate under valid licences and use state-of-the-art encryption can be considered safe options. However, since a revoked gambling concession can put the entire sister network at risk, it can be assumed that sister sites may sometimes be seen as safer options.

The best method is to see if they operate under the same licence and if they are owned by the same parent company. You can also determine if two online casinos are part of the same sister site network by comparing their terms and conditions and looking for similarities in the software that powers their websites.

Sometimes, yes. However, in most cases, sister casinos require that you create an account with each sister gambling site. To know if a casino network allows the use of a single shared account for multiple websites, check the terms and conditions of use of each platform.

Sister casinos may have the same withdrawal limits, but that is not always the case. Because casino sister sites are created to target different audiences and demographics, it is to be expected that withdrawal limits would be tailored to the specific requirements of that particular group of players. For instance, it is unrealistic to expect that sister sites that cater to high rollers would have the same limits as those geared towards casual players.

No, in most cases, even if one sister casino stops operating, the other sites will continue to work, accept players, pay out winnings, etc. However, if a casino closes due to a revoked licence or parent company problems that affect the entire network, then, yes, one casino closing may be indicative that the others will follow suit soon.

If a new sister casino is operated by an established parent company licensed by a stringent gambling authority such as the Malta Gaming Authority or UK’s Gambling Commission, it is a legitimate business that complies with strict regulatory requirements.
