What are “sister casino” sites?
It seems that the term “sister casino” is bandied about with near reckless abandon these days, to the point where it’s used interchangeably to mean different things. But what does the term
actually
mean? And how might it affect how and where you play your favorite sweepstakes casino games online?
OK, so from our perspective, “sister casino” has two definitions, so it’s easy to see why the term is used so interchangeably. You’ll see it used differently across the PromoGuy site, specifically when we’re discussing the following two topics:
- Brands that share the same parent company:
That’s right, when two or more
social casinos
share the same parent company, you might see them referred to as sister casinos. Case in point, all the brands owned by B2 Services OÜ, including McLuck, MegaBonanza, Jackpota, and others.
- Comparable brands that might serve as good alternatives to one another:
Sometimes, our readers express interest in finding alternative casinos that are similar to others they’ve tried in the past. That’s why you’ll see dedicated guides around the PromoGuy site covering sister casinos for specific brands – it’s a way to showcase alternative sites that share certain similarities, be it games, bonuses, theme, or features.
Just remember: if you see “sister casino”, it could either mean that a couple of brands share the same parent company or that they’re similar in some way. In most cases, it will be the latter, as there’s always a huge demand for sites like X, Y, and Z when our readers are searching for new sweeps casinos to try in their state.
What are the benefits of sister casinos?
You might not have given much thought to sister casinos before, but there are a surprising number of benefits that can come from seeking these out for your favorite sweepstakes gaming sites.
Let’s take a closer look at why finding sister casino sites could benefit your sweepstakes gaming journey in the long term…
🥇 Easily track down comparable sweepstakes casinos
Whether they’re owned by the same company or just thematically similar, searching for sister casinos is a foolproof way to find brands that are comparable to your favorite sweepstakes casino sites.
For example, let’s say you were on the hunt for
free sweeps cash casinos
like RealPrize. Firstly, you could take a look at the brand’s actual sister site, LoneStar Casino, which is owned and operated by the same parent company. Or, you could focus instead on sister sites that are like RealPrize, be it Spree, Jackpota, or SpeedSweeps. Either way, this is a fantastic way to link up with comparable brands that should meet your needs as an existing RealPrize player.
🔍 Learn more about a brand’s origins and reputability
Before signing up with a new sweepstakes casino, we always recommend a little due diligence, and part of that means exploring a brand’s origins, history, and reputation. To get the measure of what a sweepstakes casino is like, it often pays to look at its sister casinos, so you can see which brands it’s ranked alongside and whether its parent company owns other sites too.
Let’s say you were considering signing up at Jackpota, but were eager to learn more about the brand first. A quick search for Jackpota sister sites would reveal that it’s owned by B2 Services OÜ, a parent company that also owns McLuck – a sweepstakes casino with a stellar reputation. That should give you some peace of mind that Jackpota will be a reliable place to play by association alone.
📱 Familiar user experience and interface
If you’re set on seeking out new
sweeps casinos with no purchase bonuses, you should at least look for sister casinos that offer a similar overall user experience to your current sweepstakes casino brand. That way, there’ll be no steep learning curve to contend with, so you can focus less on figuring out the basics and more on extracting maximum value from a brand’s no-purchase promotions.
Think about it: if you’re already a member of High5 Casino, a sweepstakes casino that’s lauded for its excellent mobile app, it makes sense to seek out High5 Casino sister sites that offer comparable functionality with a rewarding welcome bonus to boot. You might, for example, choose CrownCoins Casino, which has been impressing our review team with its excellent mobile compatibility and generous welcome bonus.
🌍 State-by-state flexibility
It’s always frustrating to find out that a particular sweepstakes casino isn’t available in your state due to local restrictions. That’s where seeking out sister casinos for the brand in question can come in useful, helping you identify alternatives that may have been given the green light to operate in your jurisdiction.
For example, if you were hoping to make use of the latest Stake.us bonus drops only to find that this iconic sweepstakes casino is no longer available in your state, searching for Stake.us sister sites could pay dividends. While Stake.us doesn’t have any same-brand-owned sister sites, our experts can certainly help you find alternative casinos that are similar to Stake.us – be it Moonspin.us, WOW Vegas, or Spinfinite.
🎁 Shared bonuses, promotions, and reward programs
This benefit applies specifically to sister casinos that are connected, either by way of sharing the same parent company or as a result of a recent merger. Often, it’s possible to make use of multi-platform bonuses and reward programs, with sister casinos offering users comparable perks across two or more platforms.
You might, for example, be able to collect loyalty reward points that are applicable at multiple sister casinos, or else refer friends to one or more related platforms. Some sites may even incentivize you for checking out a newly-launched site from the same parent company, or offer progressive jackpot slot prize pools across a network of games spanning different sites.
5 of our favorite sweepstakes casinos and their sister sites
Here we go then: a shortlist of our top-five sweepstakes casinos, along with their related sister brands. Not only do these five sites represent the cream of the crop of US sweepstakes casinos right now, but it’s also easy to pick out sister sites for each of them. That includes both actual sister sites that share the same parent company, as well as brands that are closely related by virtue of their games, features, or general offering.
Stake.us – An A-rated sweepstakes casino that’s impossible to imitate
Stake.us: Pros & Cons
- 1200+ casino-style games
- Safe and legit
- Cool promo deals
- Live chat support
Not only does Stake.us not have any actual sister sites (except, of course, for its global partner brands Stake.com), but it’s a sweepstakes casino that’s almost impossible to imitate. Of course, we mean this in the very best way, but of all the sites on our shortlist, Stake.us is perhaps the hardest to find tangible sister sites for – such is the strength of its offering and output.
Nevertheless, there are certain elements of Stake.us that we can leverage to find potential sister sites, with its self-produced casino-style games being a prime example of this. While the Stake Originals collection is one of the very best ranges of self-made games around, it’s not the only brand that makes its own games in-house. For example, McLuck has its own line of “McLuck Exclusives”, and it’s a similar story at RealPrize, too.
Happy to stick with the original? When signing up at Stake.us, be sure to use our promo code, PROMOBOY, to enjoy an exclusive welcome bonus worth 560,000 Gold Coins, 56 Stake Cash, and 5% Rakeback, all of which you’ll receive over your first 30 days as a new Stake.us member.
RealPrize – Discover sister casinos for this up-and-coming brand
Pros and cons of RealPrize
- Excellent Daily login bonus of 5,000 GC and 0.30 SC
- Fast gift card redemptions often within 24 hours
- Quality sweepstakes casino games from top providers like NetEnt
- Seven-tier VIP program with increasing rewards
- PayPal supported for purchases and redemptions
- Small game library of only 200+ titles
- Live chat support limited to higher VIP tiers
- No dedicated sweepstakes casino app
RealPrize is fast becoming one of our favorite sweepstakes casinos, with a fantastic range of premium and self-produced games, generous promotions (including a 100K GC + 2.5 SC welcome bonus), and a brand-new mobile app for iOS users (sorry, it’s not available on Android quite yet). But enough about all that – what are the best sister casinos for RealPrize? Or are you better off sticking with the original?
Well, as touched on earlier, RealPrize has an actual sister casino in the form of LoneStar, which you may have noticed is sitting pretty at the very top of our sweepstakes casino recommendations list. Both RealPrize and LoneStar are owned and operated by RealPlay Tech Inc., with both brands offering a comparable line-up of games and excellent supplementary features like live chat customer support.
What is worth knowing is that if you’ve claimed the welcome bonus at RealPrize, you can still do the same at LoneStar, with the potential to unlock thousands in free Gold Coins and Sweeps Coins. So, what are you waiting for?
Jackpota – One part of the beloved B2 Services OÜ group of brands
Jackpota: Pros & Cons
- Multiple ways of playing
- No purchase necessary
- Available in 49 US states
- Daily bonus
Jackpota is one of the newest members of the hugely successful B2 Services OÜ family of brands that have taken the US sweepstakes gaming market by storm in recent years. For that reason, the site naturally has lots of closely related sister casinos, including McLuck, MegaBonanza, Hello Millions, PlayFame, SpinBlitz, and Scratchful.
Of course, Jackpota is a
very
good sweepstakes casino in its own right, so there’s no need to seek out sister casinos here if you’re happy with the original. We rate the brand highly for its slot-driven games lobby, multi-tiered loyalty program, respectable welcome offer, and its outstanding coverage across the US (it’s available in 49 US states at the time of writing).
If, however, you’d prefer improved game categorization (something we marked the brand down on as part of our full review), McLuck may be the ideal sister casino for Jackpota. Failing that, you may like to look further afield and try a site like WOW Vegas or Rich Sweeps.
Pros and cons of McLuck
- Great selection of jackpot slots, including the McJackpot progressive jackpots
- Excellent mobile app for both iOS and Android devices
- Over 700 online slots from popular providers like NetEnt
- Live dealer games available
- Claim referral bonus of up to 100 SC
- High redemption threshold of 100 SC
- Limited table game options
McLuck was the original B2 Services OÜ sweepstakes casino, and its launch heralded the arrival of the company in the US sweepstakes gaming market. That was way back in early 2023, and since then, several McLuck sister casinos have emerged from the B2 fun factory. But the question is, can any compete with the original?
Granted, we’re big fans of the likes of MegaBonanza, JackPota, and PlayFame, but we do have a sweet spot for McLuck. The brand’s head start on its sister sites is evident from its spec list, features, and games library, particularly in its comprehensive range of live casino games and McLuck Exclusives.
When you sign up at McLuck, you can grab a 7,500 Gold Coins and 2.5 Sweeps Coins welcome bonus with our exclusive promo code, PROMOGUYSOCIAL. Simply add this code during registration to claim this welcome offer, which you may have noticed is the same as other B2 Services OÜ sweepstakes casinos.
High5 Casino – Are any High5 Casino sister sites as good on mobile?
High 5 Casino: Pros & Cons
- Generous welcome bonus package
- Over 1500 quality games available
- Free daily coin rewards
- Legit with multiple licenses
- Limited table game options
High5 Casino is one of the original US sweepstakes casinos, tracing its origins all the way back to 2013, believe it or not. Still, you wouldn’t know it from the most recent iteration of the H5C site, which includes one of the most comprehensive mobile apps to be found on any sweepstakes gaming platform.
Thanks to its dedicated mobile apps for iOS and Android, High5 Casino remains one of our most recommended sweepstakes casinos. But does the site have any sister casinos that we can vouch for alongside it?
Like Stake.us, High5 Casino is its own separate entity. However, there are comparable sister sites like High5 that we can recommend, including CrownCoins Casino. This comparatively new sweepstakes casino received plaudits from our experts right away, all thanks to the inclusion of a dedicated mobile app. So, if you’re looking for sites like High5 Casino that prioritize mobile compatibility, perhaps give this sister site a try.

Try out our recommended sister casinos for your favorite sweepstakes brands
We get that the world of “sister casinos” can be a little confusing, with the term used interchangeably to describe different things. But we do firmly believe that casino sister sites are worth seeking out for all sorts of reasons, be it to find brands offering similar bonuses or simply to play on platforms with familiar mechanics, games, and features.
Remember that whichever sweepstakes casino sister sites you encounter, you can’t use them to
play free slots and win real money prizes. Regardless of their games, features, or special offers, none of these brands offer real-money wagering or winnings, so you’re better off finding a site that offers the most fun-filled and feature-packed experience.

Sister casinos FAQs
🔍 How do you know if two (or more) sweepstakes casinos are sister sites?
If you want to find out if two brands are sister casinos, check their parent companies and T&Cs. There are other tell-tale signs, too, including comparable welcome bonuses and game providers.
🔒 Do sweepstakes casino sister sites operate under the same license?
Not necessarily, no. In fact, many sweepstakes casinos don’t have official game licenses, so this kind of information may be difficult to compare.
🎁 Can you claim welcome bonuses at sister casinos?
Most of the time, yes. However, some companies may restrict access to welcome deals if you already have an account with a sister site, so check this carefully in the bonus T&Cs.
