What Is a Sister Casino?

A sister casino, also known as a ‘sister site,’ is a rebranded casino operated by the same company that owns one of the more popular gambling sites or apps today. Most sister sites have similar games, game engines, mechanics, and policies as the leading site.

Why would a casino owner open a site that might compete with their player base? To add new themes, games, and bonus structures that need to fit on their leading site.

For example, let’s say that one of the big poker sites wanted to add bingo and have a more casual vibe to attract an entirely different set of customers. They probably wouldn’t do that on their main app since drastic changes might drive away their current customers.

Instead, they would create a new website and app with different graphics and themes. This unique image is meant to attract another segment of the population. This more casual crowd might enjoy low-stakes poker, bingo, and less competitive but more fun gaming options.

Reskins

This brings up the topic of reskins. A reskin takes the guts of a popular game and adds a new theme, sounds, and graphics. At the core, it’s the same game. But the game experience is quite different, possibly more attractive to specific demographics. For example, a combat-themed slot machine might be transformed into a water balloon-themed slot, trading sounds of warfare with sounds of people getting splashed and swapping out images of conflict with pictures of summer fun. At the core, it’s the same game, but it will be attractive to completely different audiences.

Sister Casinos use it extensively to create a new mood for its site and app. They also include new games and machines that didn’t fit in on their leading site. Sister casinos are a great place to test new ideas or games that might be new to the intended market. For example, the site owner might want to popularise Baccarat in a South American setting. That is a risk that they wouldn’t take on their leading brand, but relatively easy to trial on a casino sister site.

In short: A sister casino uses the mechanics of a popular gaming site but changes the theme to attract a different set of gamers.

Why Are Sister Casinos Important?

A casino sister site is, of course, more attractively themed for the target audience. But assuming you aren’t a casino marketer, why would these sites be vital to you?

As with any newer or smaller site, you can claim attractive bonus offers. Some sister casinos only allow specific bonuses if you already have an account on the leading site. Others will allow you to claim the same first deposit bonus on every sister site as if you were a new player! We’ll discuss the different scenarios in the ‘Rules to Claiming Bonuses at Casino Sister Sites’ section.

A Fresh Start

Another reason to consider sister casinos is if your experience at the leading site is stale. Casino sister sites provide the opportunity to make a fresh start. You’ll likely encounter different players at your preferred stakes in competitive games. In solo games or games against the house, the aesthetics are more pleasing, diverse, and engaging. Various sites also have different percentages of how much money (on average) is returned to the player. A higher Return to Player percentage (RTP) might mean the difference between winning and losing.

There are often different progressive jackpot structures at sister sites as well. This means you may find yourself in the advantageous position of playing your favourite type of game with the chance at a big grand prize or a much higher percentage chance at a slightly smaller progressive jackpot.

You might also see pilot programs for interesting new features. For example, some casino sister sites offer integrated, simultaneous play of a slower game alongside a faster gaming experience. MFortune, a Dr Slot sister site, is an excellent example. They allow you to play their slot machines and 90-ball bingo rounds simultaneously. These features are generally floated as test balloons on sister casinos. And if they’re popular and easy to support, they’re rolled out across multiple sites. Playing on a casino sister site allows you to experience these newer features before anyone else!

What Is the Difference Between Sister Casinos and Similar Casinos?

A similar casino might not have the same ownership as the original site or app but has copied as many elements as possible without violating the original site’s intellectual property.

This is possible because a handful of gaming companies created many of the core casino mechanics and popular game skins. Massive gaming companies like NetEnt and Microgaming often license their machines to hundreds of casinos. Because most of them aren’t under exclusive license, it’s easy for a new online casino to offer a similar game selection to a popular casino, change the theme slightly, and brand themselves as a new thing.

Their theory is, ‘If it ain’t broke, don’t fix it.’ So similar casinos copy the success of another site as closely as possible and rely on generous welcome bonuses to attract new punters. This works for everything from slots to traditional casino games, sports betting, bingo, and beyond. Similar casinos offer a reasonably intimate experience to the original but under different management. Whether that management is better or worse depends entirely on who owns the new casino.

What Are the Four Categories of Sister Sites?

Sister sites come in four general categories.

Online Casinos

Online casinos offer an excellent general gaming experience. They often have a mix of competitive games (poker, competitive blackjack, etc.), games against the house (regular blackjack, Baccarat, etc.), slots, bingo, sports betting, and general event betting. These are the jack-of-all-trade gaming sites offering a little bit of everything.

Online Betting

Online betting is geared towards wagering on sporting events and the outcome of certain world events. Sports betting includes everything from FIFA to rugby, from E-sports to equestrian events. World event betting contains:

  • Things like the outcome of an election.
  • The results of TV or movie awards ceremonies.
  • Even the birth date of a power couple’s baby.

You can either bet on the outcome of a single event or parlay the results of several works for a shot at a significant effect.

Online Bingo

Online bingo sites are a virtualized bingo club experience. They try to emulate the community bingo atmosphere fostered at the local clubs around the UK. In addition, they offer prizes for accomplishments that are more easily tracked digitally, ranging from progressive jackpots to loyalty programs.

Online Slots

Online slot sites specialise in virtual slots of all genres. Their bread and butter offer slot machines with various bonus and progressive jackpots and mini-games that directly impact the session’s outcome. There are also ‘megaway’ machines with 10,000 or more ways to win on each spin.

Of course, the nature of sister casinos is branching out, so you’ll sometimes see hybrid sites that offer a superior selection of one thing and a little side dish of another. For example, a bingo site also does online social betting based on televised events. The possibilities are endless.

The most popular hybrid type is slingo. These sites offer unique combinations of the slot and bingo experience. They also cater to various slots and bingo where you can play simultaneously.

Many different kinds of sister casinos will offer virtual scratch cards. These don’t fall under a particular category of gaming sites. They’re just additional ways to have fun.

What Are the Pros and Cons of Sister Casinos?

So do you have a better or worse expected value (EV) when you play at a sister casino? That depends on your usual games, habits, the site’s average RTP, and what bonuses and loyalty points you can use.

Let’s lay out all of the good and bad points of sister casinos so that you can determine on a case-by-case basis whether or not they’re right for you:

Pros:

โ—     Possibility of Earning New Bonuses:

Assuming the leading site’s policy allows you to earn new player perks and deposit bonuses, that’s one of the biggest draws to try a sister casino. These can range from cash deposit bonuses to free slots and roulette spins to mini-games that can earn bonus money. Even the companies that prohibit claiming ‘new player’ bonuses on casino sister sites will often honour ‘reload bonuses.’

โ—     Larger Chance of Winning Progressive Jackpots:

Depending on how the casino structured the progressives, you might have a bigger chance to win progressive jackpots on less populated sites, though the total prize pool is commonly smaller. There’s less overall competition, so loyal players on smaller sites have more time to hit that one-in-several-million shot. The flip side is that the progressive jackpots will be relatively minor, on average.

โ—     Avoiding Burnout:

Sometimes, it’s nice to see fresh graphics, hear new sounds, and play in a contemporary atmosphere with an entirely different group of people. Sister casinos offer you the chance to play familiar games in a brand-new way, combining comfort with the rush of trying something new. Even though ‘changing your luck’ is mostly a myth, changing your attitude is genuine since the odds at these sites are often similar. If you feel better, you can play better.

โ—     New Competition:

Particularly in player-VS-player games, changing the scenery also means changing the competition. You tend to avoid the same old ‘grinders’ and often have the chance to play with freshers’ faces. This means you can become the big fish in a smaller pond.

โ—     Keep Payment Methods and Validation Across Sites:

Because most sister sites have the same back-end banking and payment processing system, you can use the same payment and cash-out methods between sites. This reduces the hassle of investigating and signing up for a different way to get your money in and out of the site. Similarly, sister sites often use a shared login across their various sites. That means no need to verify your identity multiple times, and you don’t need to create and memorise a new password.

โ—     New Things Can Be Fun and Exciting:

Lest we forget the ‘game’ part of gaming, trying something new can be a fun experience. New games, images, and sounds also increase our dopamine levels so that they can be exciting. If you’re playing for entertainment and always play within your limits, there’s no reason why sister casinos can’t simply be a way of having a new kind of fun.

Cons:

โ—     Splitting Your Loyalty Points:

If there’s any loyalty points program on your favourite online casino or gaming app, the loyalty points program might not extend to its sister casinos. ‘Loyalty points’ might have many different names, but they include any score or credit earned over time when playing on that site. Usually, the rewards for keeping your loyalty points on a single site have more value than splitting them up between multiple smaller sites.

โ—     Smaller Progressive Jackpots:

As mentioned before, fewer people participating in progressive jackpots might give you a higher chance of winning, but you’ll win less on average. This needs to be calculated into the site’s EV, even if the chances of winning are relatively small in the first place.

โ—     Less Streamlined Support:

Because they’re dealing with new features and policies, support for more unknown sister sites might not be as slick and streamlined as you see in older casinos. They might still be developing all of the FAQs and support scripts that deal with the more common scenarios, and you might encounter bugs they’ve never seen before. It’s the same risk you take when trying out any new software: In some ways, you’re helping them test out new features in a live environment. So you’ll need to be extra patient when filing support requests.

โ—     New Things Aren’t For Everyone:

Some people will find something they like and never see the point in trying something new. And that’s fine! If you’re happy with your current site or app, you should continue to enjoy it.

What Are the Rules for Claiming Bonuses at Casino Sister Sites?

Different parent companies have different rules regarding their casino sister sites. Some treat each app and their sister site as different player experiences, allowing anyone to take advantage of new deposit and reload bonuses despite already being a member of other sister online casinos. Others strictly enforce their policy to allow only one new deposit bonus across their entire suite of sister casinos. They keep reloading bonuses even if the deposits are to a sister site.

Generally speaking, the sister casinos that let you register for multiple sites in their portfolio with the same E-mail address will let you claim new player bonuses on each site. This is great for the player, as they have more incentive to play there. And it’s excellent for the sister casino since they’re trying to promote and popularise their alternatively branded site.

This is one of the most common topics we report here at Sister Casinos. Some people want to maximise their winnings by taking advantage of new deposit bonuses, clearing them as quickly as possible, and moving on to the following qualifying site. It would be a waste of time for players to register on a sister casino that won’t offer them the new deposit bonus simply because they’ve already registered on the parent site.

The Rules

Other sites might not allow a new player bonus on a sister casino if one has already been claimed on the main site or app, but they will enable reloading rewards. This is why these topics need to be tracked separately. Policies also change, so you must perform periodic policy checks and updates to portray a parent company’s bonus policy accurately.

A minor issue that can matter quite a bit to dedicated players is whether or not loyalty points span between all the sister sites. This is a rare scenario, but it can benefit the player when it happens. There are even some cases where a brick-and-mortar casino will share its loyalty program with the online version of its brand. We’ll let you know when loyalty points are shared between multiple sites.

Please let us know if we need to update something on the sister site’s bonus policy. We’ll update our website with the latest information after confirming the policy with the casino.

Do I Need a New Account for a Casino Sister Site?

Usually, the answer is ‘yes,’ but that policy is entirely up to the parent company.

For example, Sky makes you use the same account across Sky Bet, Sky Vegas, Sky Bingo, Sky Casino, and Sky Poker. If you register a separate statement, it will be frozen. So, in that case, all sister sites use the same login information. We often see this policy across sister sites when they share a big brand name (Sky, Party, etc.).

However, plenty of sister sites have you register separately and only care if you use the same E-mail address as you’ve used on other sites in their casino family. This is great because it indicates you can use the new player deposit bonus.

We’ll be keeping an eye on these trends and policies as we advance and will report any significant developments.

How Are Casino Sister Sites Licensed?

Every casino sister site must be put into the UK Gambling Commission’s public register. We provide the link to the operator’s general business license whenever possible. From there, you can check out all of the domain names that they claim responsibility for (listed as ‘active’), the sites that they used to run in the past but are now defunct (listed as ‘inactive’), and rebranded or leased sites that have been issued under their general license (listed as ‘white labeled’).

Additionally, you can see if they have any alternative names for their business (known as DBAs or ‘Doing Business As’) and any regulatory actions and sanctions that the Gambling Commission has levied against them.

Since 2020, the Commission has started to publish public statements about casinos, sister sites, and the owning organisations that have done something that should be brought to the public’s attention. Submitting inspections and agreeing to allow these public statements are part of the licensing terms that every casino owner agrees to if they want to operate in the UK.

What Are Some Examples of Popular Casino Sister Sites?

Some of the most well-known sister sites belong to Gamesys Operations Limited. They are a massive corporation with many casinos and apps that you’ll immediately recognize by their brand names and advertising: JackpotJoy, MegaWay, Rainbow Riches, Monopoly Casino, Virgin Games, and many more.

Rainbow Riches has an associated bingo site, slot site, and casino app. All of these are sister sites of Rainbow Riches, which is itself a sister site of Virgin Games and all the rest.

ProgressPlay Ltd

You can get these sprawling organisations of sister sites, many of them primarily rebranded properties with reskinned games. The absolute king of this practice is ProgressPlay Ltd.

Even discounting the 60 or so static properties, they hold 130+ white casino labels and active domains! ProgressPlay’s network includes Mr Slot, Mr Vegas Casino, and Monster Casino, among dozens of others.

Of course, one of the sites that has been around for decades and arguably started the entire online casino craze is Party Poker. These days it’s owned by LC International Ltd. And as you’re about to see, the number of sister sites they promote is titanic.

LC International Limited

LC International Ltd is also known as Party Poker, Coral, Foxy Bingo, Gala Bingo, Ladbrokes, and SportingBet. These sister sites represent massive casino and sports betting traffic in the UK. They cover all four categories of sister sites and branch into some of the most niche gaming content available online. Not only that, but they’re international operators with similar titles available in the USA, the EU, Asia, and beyond.

This is the true scope and power of sister sites. Casual and professional gamblers can create a living, breathing gaming ecosystem when they flock to these sites. That means vast prizes, progressives, tournaments, and seasonal events. And, of course, for anyone looking for a smaller and more intimate experience, smaller sister sites like Cheeky Bingo and Bwin are available with the same level of trust and quality of support that these more prominent names offer.

These are some of the older, more established sister site networks. But what about the sister sites that have recently expanded?

What Are Some Examples of New Casino Sister Sites in 2023?

Some exciting casino sister sites have opened in the last couple of years and are already making a big splash.

In Touch Games, Limited is the parent company for many unique properties. They make the vast majority of their games in-house, so you are likely to encounter quite a few individual titles. Best known for mFortune and Dr Slot, they recently launched Jammy Monkey as their latest casino sister site. It was an instant hit. Jammy Monkey is one of the fastest-growing online casino properties in the UK and an excellent example of how a sister site can rapidly become just as popular as the originalโ€ฆ if not more.

888 Bingo

Sometimes, a sister casino is bought rather than made! Recently, Grand Battery Holdings Limited bought 888 Bingo from the original owner. Because of this, 888 Bingo unexpectedly got pulled away from the other 888 properties and became a casino sister site of Costa Games, Posh Bingo, Wink Bingo, and Wish Bingo.

Whenever another group buys a big property like 888 Bingo, questions arise. Will the site need a separate login from its new sister sites? Is it going to be brought into the fold regarding bonuses, policies, and support? Will it remain as generous as it used to be, or have the odds changed? We’ll be carefully tracking the progress of 888 Bingo to see how well Grand Battery Holdings is integrating it into the rest of their family.

BetVictor

A minor example of a new sister site is brought to us by BV Gaming Limited. The ‘BV’ stands for a site that many of you will be familiar with: BetVictor. For a long time, that was the only site that they ran. Eventually, they branched out with the sites Parimatch and TalkSPORT BET.

But more recently, they came out with the sister site Heart Bingo. This was a smash hit, winning the 2022 Best Pragmatic Play Bingo Site award. They combined mini daily jackpots on both slots and bingo rooms with rolling mega-progressive jackpots that paid out in the millions! It was a strategy that catered to casual and dedicated slingo players. Heart Bingo proved that a company could handle dozens of sister casinos to succeed. They need a handful of well-maintained, well-loved properties that people can relate to.

We will explore plenty of the recent examples, with hundreds of new sister sites in the works, both on the international stage and specifically within the UK. We’ll single out the most exciting offerings over the next few months and feature them both on the Sister Casinos home page, as well as on social media and in our blog.

What Is a Mono-Brand?

The opposite of a casino sister site is a mono-brand. These casinos run as the only online asset in their owner’s portfolio. You’ll often see mono-brands in conjunction with medium-sized brick-and-mortar casinos and themed sites trying to break out with a new online offering.

We scour the gaming news feeds, watching for mono-brands that announce their intention to launch their first sister casino. We’ll share such announcements with our community if there are any promising offerings to bring to your attention.

Can I Contact Sister Casinos If I Have More Questions?

Of course! Use our contact form for questions, new sister casino site suggestions, or press inquiries. We’ll be happy to help you out!

Our Mission

You might wonder why we’re doing all this research and education. After all, we’re just gaming affiliates at the end of the day. We make our money when you click on a link. So why put in all this extra effort to educate our customers and provide links to government and private resources?

Part of our mission at Sister Casinos is to match players to the sites and apps that will make them happy. It might be a little folksy or naive, but if you find quality sites and well-researched information here, you’ll tell your friends about us. Please link this article on social media or mention our website in your blog.

We do the extra work because this website isn’t just about affiliate links and making money. It’s about improving the time that people spend on their entertainment. We hope we’ve done that in our way.
