Mr Mega used to be powered by Aspire Global, both in terms of licence and platform, but the site ceased operations at the end of February. Aspire Global has also stopped working in the UK, so we have listed some good alternatives below instead.
Mr Mega had quite a lot of sister sites before it closed down. If you want to find out which those sites were, we have listed them below.

The ownership of Mr Mega is a little bit tricky to find information on, with it not being displayed on the site. However, we found that the brand is owned by Apex Marketing Limited. To which the follow-up question would be: Does the company own any other sites?
While the answer to that question is no, it doesn't mean that there aren't any sisters for punters to join. Quite the opposite, as there is a plethora of sister sites through Mr Mega's platform provider, Aspire Global. We have listed these above.
Seeing as Mr Mega is operated by Aspire Global, there are quite a few sister sites to explore as you can see above, but we have picked out three below.
Finally, we have gone with Bet442 here, with the main motivation being that it hosts a casino and a sportsbook, just like the aforementioned Luckster.
The sportsbook is rather good all things considered, offering a multitude of different markets for a range of different sports. The casino, meanwhile, hosts a number of the best providers as well as popular games.
There are certainly better 'all-in-one' options on the market. However, Aspire's offering here is good enough and is definitely worth trying in our view.

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.
At FindSisterSites, I'm responsible for testing bookies and providing our readers with the necessary sister sites insight. I try to make the most of my previous encounters with bookies to highlight what is good, bad and in between.
