Red Casino is owned and operated by Jupiter Gaming Limited, making it a sister site of Mr Luck, Dream Jackpot, 666Casino, Lad Bet, and more.

Yes, Red Casino has several sister sites to check out. The fact is that there used to be even more of them, but since the switch from Aspire Global (which exited the UK market), the number is more modest. Indeed, the owner Jupiter Gaming has fewer than ten sites right now.
Less is more in this case, without a doubt. Several of Red Casino's former sister sites used to be very poor and frankly not worth joining. Now, however, the sites are much better thanks to the platform of GiG. This is used on all of the Jupiter sites.
Seeing as Red Casino used to be operated by Aspire Global, there were quite a few sister sites to explore.
Mr Luck is probably the most obvious option here for the best sister site. Just like Red Casino, the site is operated by Aspire but the links go further than that. In what way? Well, Jupiter Gaming owns both sites.
Primarily, the site focuses on casino, but there is also a sportsbook for punters to check out if they want to. Both sections hold up well in the industry, especially against some other brands on the licence.
The interfaces are pretty similar, though the actual sites have a few differences. Admittedly, Mr Luck feels slightly more upmarket, and better quality for what it's worth.
Sticking with the Mr theme, we'd also recommend Mr Play. The site is quite similar to Mr Luck as it features a casino and sportsbook. Again, though, the sports area does feel like the lesser priority.
That isn't to take anything away from its quality, but rather the focus is more on the casino side of things; ultimately, though, this is understandable.
The casino interface is slightly different from Red Casino, but ultimately both are rather similar if you make an overall assessment. In short, you will not feel lost on the site, but the changes are visible.
Finally, Dream Jackpot is a site to consider. Admittedly, the site does look a little messier, but there are still some good things offered.
There are certainly some more niche games available on the site, most of which are time-limited, so things such as Christmas games. However, some may prefer these themes and feel luckier with them.
Flaws are present, definitely, but if you aren't too fussed about appearances, then you will be fine here.

I would describe myself as an experienced punter, having taken a liking to horse racing in particular. My interest in sports is also what made me pursue a career in writing, graduating with a Bachelor's Degree in Journalism from UCFB in 2024.
