HeySpin used to be powered by Aspire Global, both in terms of licence and platform, but now it's operated by Jumpman Gaming instead. Since we don't recommend joining one of the new sisters, we have listed some good alternatives below.
HeySpin had quite a lot of sister sites before Aspire Global left the UK market. If you want to find out which those sites were, we have listed them below.

HeySpin's ownership is a rather interesting one, with many believing that the site was owned by Aspire Global. However, this is not the case as the site was acquired by Hurricane Global Group in 2021, which is the company that has owned it since.
In fact, there are no ties whatsoever left with Aspire Global, as the licence and platform provider decided to leave the UK market. HeySpin, as such, moved over to the Jumpman Gaming licence and platform so there is definitely not a lack of sister sites.
Seeing as HeySpin is operated by Aspire Global, there are quite a few sister sites to explore. We have taken a closer look at some of these below.
Another option worth considering is Bet442. The site offers an equally generous sign-up offer, and this is already enough reason to at least try the HeySpin sister site.
The site is predominantly focused on sport, as the name would infer, however, that does not mean that the casino section of the site is left to its own devices. In fact, both areas are of good quality, which is rare for an AG product, admittedly.
Furthermore, the site does have a mobile app, which only helps things and makes the site more worthwhile when considering a sign-up. Especially when considering that most sites with the same operator don't offer one.

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.
