Rialto Casino sister sites include well-known brands like Grosvenor Casino and The Vic, whilst other names like Lucky VIP and Bella Casino are amongst another 10 or so brands under the Rank Interactive (Gibraltar) Limited licence (UKGC: 57924).
Rialto Casino falls under the ownership and operation of Rank Interactive (Gibraltar) Limited (UKGC: 57924), sometimes known as Rank Group.
Rialto is just one of 15 different domains that sit under the Rank Group licence, with those brands having a variety of backstories.
The licence holder is what knits them altogether though, and that licence has been held since the first quarter of 2022.
With plenty of domains and good experience behind the scenes, the Rialto Casino sister sites should deliver to a high standard. Let's find out if that is true.

Rialto Casino does not have the game depth to compete with the bigger brands of the casino industry, but it certainly looks the part. It boasts a black background with a gold logo and same colour used for text on the site. It all blends together well.
The site manoeuvrability is then reasonably solid too. There is a header bar, which has functionality to scroll horizontally for category level navigation. Alongside this scroll bar is a text search function, allowing direct targeting of game titles.
In the game lobby below, you have several hundred games to explore. These include plenty of well-known names, such as "Game of Thrones", with Rialto having a number of top software companies providing games.
The library layout is simple enough to interact with, courtesy of large game tiles that are neatly spaced. There are some inconsistencies in the lobby though.
One of those comes in the shape of different sized tiles, which is fairly common practice in the industry, and the other presents with the navigation of the tiles. Some sections are a fixed page width, others work on a horizontal scroll.
Rialto Casino is best described as a solid casino platform. Not spectacular but solid enough. There are some strong elements to it though, which give Rialto Casino sister sites a good base from which to build.
Put Magical Vegas next to Rialto Casino and you will see that they’re sister sites. Structurally, they take on a very similar appearance, however, the two brands are shopping for a very different market. You can see that based on the way they position their respective designs.
Whist Rialto has that premium-leaning feel, Magical Vegas appeals to a more slot-heavy audience and, from an overarching marketing feel, it’s not as upmarket. Despite that, there are still elements of the site we like.

The site header is easy to navigate, whilst the game lobby itself is neatly packaged and highly responsive. It operates exactly the same way as the Rialto lobby.
Beyond that, you’ve then got the banking options to consider. This is another point of similarity between the brands – and a good one too.
There are multiple payment methods, including debit cards, PayPal and Trustly, whilst the minimum deposit of £10 isn’t terrible either.
Regal Wins is not just a sister site. It's a dead ringer in almost every single aspect.
From a design perspective, the only real difference between the brands is the logo in the top left corner.
The site header and search functionality is the same, the layout of the game lobby is very similar, and the manoeuvrability around the site is replicated too. Even the colour schemes and premium feel are shared.

What that means is that you have another Rank Group site that puts big-name games - across slots, table games and a live casino - in the palm of your hand, with smooth interaction and a tidy selection of payment methods to boot.
Grosvenor takes some beating where sister sites are concerned. In fact, we are pretty comfortable claiming it's the strongest of the brands we've mentioned here.
From a slots perspective, it is much like Rialto Casino. It offers hundreds of games, ranging from exclusives through to household known titles. Grosvenor boasts an excellent live casino, including a host of poker tournaments too. That makes it a step above on the casino side of things.

Then, to further elevate itself above other Rialto Casino sister sites, it also provides a sportsbook. With betting margins of 5.44% (in our testing), a ballpark of 30 sports covered and, underneath, that a more than reasonable market depth, it really has the potential to serve as a one-stop shop for all your gambling needs.
The navigation and design of the site, meanwhile, matches closely to other domains we've named.
