Does Mr Luck Have Any Sister Sites?
Mr Luck used to be operated by Aspire Global, plodding along without finding any real success. However, as the platform provider left the UK market in the summer of 2026, Mr Luck was forced to find another provider and landed on GiG.
The owner of the site, Jupiter Gaming Limited, has other sites under its umbrella too, which means that there are Mr Luck sister sites to join. Most of these also used to be part of the Aspire Global partnership, but we would argue that they are much better now.
Mr Luck Sister Sites Reviewed
With Mr Luck's roots now with Jupiter Gaming, there are numerous sister sites to check out (as highlighted above), but we have taken a closer look at three of them below.
🥇 Best Sister: Lad Bet
In terms of complete options, Lad Bet feels like the best of the Jupiter offerings. Indeed, the site throws up a sportsbook - alongside its casino - giving players and punters a complete experience.
It means that there is something for everyone and this shows with the actual options in each area. Starting with the sports section, there are more than 20 different options available, each with a large range of markets.
Then, the casino holds up too, even if it is not primarily a casino site like the others on this list. Unfortunately, there is no exact number of games available. After speaking to the live chat, though, we found that it's in the hundreds.
No complaints here for a very complete site.
King Casino
King Casino takes a step back towards solely being a casino site, even if this isn't a problem, of course. In fact, it may be preferred for some and that's why it's second on our list.
Our big frustration with King Casino comes in the live casino area. Right now, it is not advertised as available. But if you search for typical games in this area (blackjack or Crazy Time, for example), you'll be shown them.
If this were shown in the main area, it'd push for the top spot. Of course, it features all of the classic online slots areas, too. So it does most of the basics right.
666 Casino
Finally, we move to 666 Casino, which has a slightly different interface from its previously mentioned sister sites. Yet you can still tell it is from Jupiter Gaming.
Unfortunately, nothing plays into the theme of the name, making it a pretty generic casino. Perhaps this could be said about all three of the sites we're suggesting, though.
If interfaces do not bother you, then there will be nothing stopping you here. Different sections are outlined clearly and there is a fantastic range of different games, including the Big Bass series and Gates of Olympus.
It's alright, nothing more, really.
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.
