RightBet is owned by BigWin and operated by Betable Limited. Sister sites include Ivy Bet, Bet442, Ivy Casino, O'Reels Casino, Rose Casino, Hotstreak Casino and Hollywoodbets.

Yes, there are sister sites to join. Rightbet's owner BigWin Affiliates has not only partnered up with the platform providers Betable and Delasport for RightBet, but also for the likes of Bet442 and Ivy Bet. If we just focus on Betable, you also have sites like Rose Casino, O'Reels Casino and Ivy Casino to consider.
Another interesting thing to note is that Delasport works with Hotstreak Casino and Hollywoodsbets, which in turn means they can be considered as sister sites too. Of course, that is only on the sports side so keep that in mind before thinking that they are exactly the same casino-wise too.
Below, we have highlighted some of RightBet's sister sites, more specifically two with the Betable link and one with the Delasport link.
Bet442 isn't technically a new site, having been around with the Aspire Global platform for a few years, but the relaunch with Betable took place in 2026. Therefore, in many ways, the bookie is very similar to RightBet and that also applies to the actual features.
The new Bet442 site looks much nicer compared to the old one, but it's not just the design that makes a difference. Indeed, the market depth is very good and you will also find some good promotions on the site, which is something that many value highly.
The only negative for RightBet customers would be that Bet442 is more or less identical, so you don't get much new by switching to the site.
Ivy Casino has been around for a while, just like Bet442 that we discussed above, but the sportsbook was added in 2026. The fact is that Ivy Casino has opted for a different domain for this section, which suggests that the addition isn't just for show; there is an actual plan behind it.
It's only right to make a meal out of the sportsbook as it's quite a good one, from design to market depth and beneficial promotions. While not as good as the best bookies out there, we can still see a place for it (which we don't always say about new entrants).
Just like Bet442, however, the only negative is that RightBet customers might find Ivy Bet too similar in the sense that you don't get much extra or new stuff.
Hollywoodbets differs a little from the other sites highlighted as the only link with RightBet is the sportsbook. The well-known casino and betting brand partnered up with Delasport after leaving Betconstruct, which was a huge improvement at the time.
It would definitely be fair to say that the purple-themed brand is the best here, not just because of the reputation but also because the casino is miles ahead. Maybe that doesn't matter as much to sports punters, but it does say something about the overall quality.
Promotions for existing customers aren't lacking either, while there is also a feature called 'Missions' to reward loyal customers.

I'm the founder and editor-in-chief of FindSisterSites. After exploring how betting and casino sites are structured for another project, I felt that there was a gap in the market, more specifically for correct, reliable and up-to-date information on the companies behind each site.
As such, I'm responsible for identifying the 'hidden' sister sites and debunking a lot of the incorrect information that spreads around the web. My background in journalism certainly means that I have the perseverance to find the right answers, which helps in this case.
