Luckster used to be powered by Aspire Global, both in terms of licence and platform, but the company's decision to leave the UK resulted in Luckster and its sister sites shutting down. Below, we have listed some good alternatives instead.
Luckster 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.

When active, Luckster was backed by the white-label operator Aspire Global, which was also known as AG Communications per the UKGC licence.
There were many sister sites to join and if you had the chance to try one of them while they were still live, you would have noticed that the features and interfaces were almost identical.
A couple of the sister sites, namely Mr Play and ZetBet, also shared the same owner (Marketplay Ltd) beyond the white-label partnership.
Seeing as Luckster is operated by Aspire Global, and owned by Marketplay Ltd, there are quite a few sister sites to explore. We have taken a closer look at some of these below.
Considering the sites are all effectively the same product, just with slightly different benefits, it is difficult to identify the best overall site. However, if you were to suggest Bet442, you probably would not be wrong.
The site offers, in our opinion, the most generous sign-up offer, which has to be appreciated considering how poor some of the other offers are. Furthermore, the bonus is better than Luckster's, at least if you look solely at the amount.
Additionally, the site is one of the few AG brands to boast a mobile app, which is automatically a huge boost to its rating.
Another site worth considering is Mr Luck, which also offers an equally generous signup offer like Bet442. This is instantly a big plus for us, though you could argue that Luckster's offer is better given the lower deposit amount.
Furthermore, the sportsbook is above a passable grade, which is more than a lot of the AG brands can say. However, the positives probably stop there, which is a shame considering it has the actual product in a good place.
At present, the betting margins are probably a tad too high to make the app worth using regularly. With that said, these are fixes that can be made, and if they are, it would bode well for the future.
Finally, we would highlight ZetBet, which was founded in 2022 and has the same owner as Luckster (as already mentioned). It certainly has a lot of positives to it despite being a relatively new bookmaker on the UK scene still.
Indeed, the site has some nice foundations, which can certainly be built on, though there is still a distance to go before it is considered a 'good option' for customers. However, this is a common theme with products offered by Aspire Global, unfortunately.

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.
