Rollbit sister sites include the likes of Royale Lounge, Cosmic Spins, Vegas Wins and The Residence, with each of these brands - and many more - falling under the licence of Grace Media Limited.
Since Grace Media works with the platform provider Betable, there are even more Rollbit sister sites beyond the licence, some of which we have listed below.
Below, you can find all of the sites that are listed under the Grace Media licence together with Rollbit.
Rollbit is one of several domains that fall under the operation of Grace Media Limited. However, the owner is actually Bull Gaming and not Grace Media, which is also confirmed by the 'white-label' status on the UKGC site.
Either way, Grace Media's licence dates back to early 2022, with the company licensed to operate across a host of different markets in the UK, including bingo, casino and sports betting.
With many different brand names falling under its licence, it is fair to say Grace Media boasts considerable experience of what the modern-day bettor demands from a platform, despite being relatively young in terms of its licence dates.

Rollbit provides punters with a solid yet unspectacular path into the world of online casinos. There isn't much wrong with the site, but it does lack that special something that makes it stand out in what is a competitive landscape.
If you choose to join Rollbit, you'll find depositing funds easy, with a host of banking options available to you, including debit card, Apple Pay and MuchBetter, which is a fairly common feature across the Grace Media network.
Once on the platform, you will find a reasonable selection of games too. There are around 1,000 titles offered in total, with big name brands like Pragmatic Play, Relax Gaming and Blueprint providing games that are genuinely recognisable titles.
You can navigate across this game library well under the "Games" menu heading as well, with a search and filter tool available.
The look and feel of Rollbit is fine too, with cleanly laid out game tiles of a decent shape and size. 1,000 games isn't market-leading by any stretch, though, and with no sportsbook or bingo hall to complement the offering, it's just not the finished article.
Rollbit serves up what is essentially a solid online casino site, but it's nowhere near being able to compete with the best brands in the business.
Is that true of all Rollbit sister sites? Or do some deliver a sizeable improvement on what is a reasonable baseline?
If you are looking for a replica of Rollbit, look no further than Vegas Wins. The two sites are almost clones of one another, albeit Vegas Wins brings a little more pizzazz to its design, courtesy of some electric colour choices, which are used sparingly across the site for a smart looking platform.
Beyond a minor aesthetic difference, everything you look at will be the same. The menu structure is the same as Rollbit, the game filtering options are the same and the game lobby looks basically identical too. That similarity spills into the quality and quantity of the games offered too - not just the layout.
With banking options and customer support ticking the same boxes regardless of which domain you opt for, it's quite plausible your choice of preference comes down to the "personality" piece. For us, Vegas Wins wins that contest, making it marginally the better platform.
Royale Lounge is another Rollbit sister site that you could accuse of being a replica, if focusing solely on the casino platform. Thankfully, there is more to Royale Lounge than just the online casino games. Step forward the Royale Lounge sportsbook.
Not only does this Rollbit sister site boast a sportsbook, but it's a pretty good one too. You will find in excess of 30 sports to bet on, with worldwide coverage across those sports and market depths that are extremely competitive with some of the best-known brands in the business.
It's not perfect, though. Betting margins run north of 9%, which is high, and horse racing isn't amongst the sports covered.
If those couple of factors don't deter you, the structure and layout of the sportsbook is really quite good too. The colour scheme of grey and blue works well, menus are easy to navigate and the odds are easy to read, explore and bet on.
We end our look at the Rollbit sister sites with a brand that gives away its offering in its title - The Residence Casino & Sportsbook.
Lo and behold, The Residence gives punters the chance to dabble across both casino and sports markets - and it does so pretty well, making it a very, very close match to Royale Lounge. In fact, the offering between these two brands is exactly the same.
You'll get 30-odd sports to bet on, event coverage from every corner of the globe, market depths than run at least a couple of hundred deep on football fixtures and the same lofty betting margins of 9.44%. The latter point is a slight negative on an otherwise solid sports offering.
As for the casino, that is a giveaway that The Residence is a Rollbit sister site. Look past the difference in colour scheme, which is a smart-looking beige at the former, and you have the same 1,000 game titles, with the same structure and the same filtering choices.
With all things considered, we'd peg The Residence as the best of the Rollbit sister sites.
