Who Owns King Casino?
King Casino has been around for a little while, with it first coming to market under the stewardship of AG Communications Limited (UKGC: 39483).
Now, though, it is owned and operated by Jupiter Gaming Limited (UKGC: 67098).
Jupiter Gaming has only held its licence since the summer of 2025, but it has made bold moves in the marketplace.
King Casino is one of several domains that have moved under Jupiter from other licence holders, whilst there have also been a couple of startup brands brought to market under its ownership.
New or old, however, King Casino sister sites are not in short supply.
What Are the King Casino Pros and Cons?
King Casino is a casino only betting platform that combines easy navigation with big name brands, courtesy of the partnership it has with some of the most reputable software companies in the business.
Pragmatic Play is the one that does most of the heavy lifting, bringing brands like Big Bass and Gates of Olympus to the party. The overall game collection is fairly limited, though, with just over 500 titles offered. Don't get us wrong, that isn't a terrible offering, but you might expect more considering King Casino is a casino-only platform.
The look and feel of the site is in a similar category, which is probably best described as somewhat average. Everything is fairly intuitive and buttons are responsive, however, the scrollbar is quite blocky. It is a minor point that gives the casino a more value-end, older fashioned leaning vibe.
The game tiles, however, are strong. They are well-sized, excellent for interacting with on a mobile device and the rounding of corners helps the lobby feel a little more modern.
King Casino Sister Sites & Alternatives Reviewed
King Casino is a tidy enough casino site, but it does feel like it could do more - both in design and depth of offering.
Will any of the King Casino sister sites improve on what is offered here?
Dream Jackpot
Dream Jackpot has been on a journey similar to its sister site, King Casino, having also started as an AG Communications brand, before now being part of Jupiter Gaming.
When standing the two sites next to one another, they look quite different. Dream Jackpot opts for a white background - instead of grey - and the scroller bar that serves as the key navigation tool over the casino game lobby is much more modern and cleaner looking too.
Scratch a little deeper, though, and it is apparent just how similar the actual offering is. The brands share the same limited, but well-respected, software providers and, again, the 500-deep game collection is heavily propped up by Pragmatic Play. That isn't a criticism, they're one of the biggest software providers in the industry, but it does put a lot of eggs in that one basket.
Punters can get started easily at both brands too. The sign up process is seamless and deposits can be made via debit card or Apple Pay, with deposit minimums sitting at only £10.
Mr Luck
Of all the sister sites we're going to touch on, Mr Luck is probably the closest we get to a full replication.
Both brands come with a dark theme, with Mr Luck boasting an all-black background, whilst the site logos are positioned in the same place, and the scrollbars that run over the casino lobby are presented in a very similar structure too.
With that all said, we give slightly more kudos to Mr Luck on the design front; the use of bright green highlighting across the site is something we like; it helps to create some cut-through when browsing the game library.
There aren't any real differences within the collection of games themselves, though. Both brands offer up approximately 500 games. Expect to see titles like Wild Wild Riches, Congo Cash and Big Bass Bonanza featuring regularly amongst the "Hot Slots".
You can also search the casino yourself, utilising a text search filter that can be used to target specific game titles or game providers.
Lad Bet
Lad Bet is the newest of the Jupiter Gaming collection, having only launched in June 2026.
We're pretty adamant that it is the best of the sister sites though, albeit it does take a little explaining to understand the brand in all its glory.
When you first navigate to Lad Bet, you'll be impressed by the look and feel of the site, but the headline takeaway is that it is a sportsbook. Clearly, with King Casino being a dedicated casino, that is a huge point of difference.
The main takeaway you need to understand about the sportsbook at Lad Bet, though, is that it is very good. Betting margins are competitive at 6.29%, sports coverage is solid at 28 sports - with horse racing a notable omission - whilst market depths are strong too.
Where things get slightly grey is that Lad Bet also offers a casino - sort of. From the Lad Bet main menu you can cross to a "Casino" button, which takes you to Lad Casino; this is a separate domain that will work with the same login credentials as Lad Bet.
Once logged in, the underlying quality of the casino is a complete replication of what you get from King Casino.
Should you be tempted by Lad Bet, it should be noted that deposits can only be made via debit card.
