Mainstage Bingo is a bingo and casino site managed by White Hat Gaming Limited. If you want to know which other sites belong to the same company, the answer is not a matter of opinion. White Hat Gaming holds one Great Britain operating licence, and every domain it runs under that licence is listed in public on the Gambling Commission register.
We pulled that register entry on 7 September 2026. Account 52894 carries 39 domains. Only seven of them are marked Active, and www.mainstagebingo.com is one of the seven. Those six other Active domains are the real Mainstage Bingo sister sites, and everything below is taken from that register page and from the footer of the brand site itself.
Mainstage Bingo sister sites on the White Hat Gaming licence
Seven domains sit under account 52894 with the status Active. That is the whole own brand family as the regulator records it today, Mainstage Bingo included.
| Domain on account 52894 | Register status | Our page |
|---|---|---|
| www.mainstagebingo.com | Active | This page |
| www.gdaycasino.com | Active | G Day Casino |
| www.hellocasino.com | Active | Hello Casino |
| www.skolcasino.com | Active | Skol Casino |
| www.slotnite.com | Active | Slotnite |
| www.21prive.com | Active | Not yet covered |
| www.diamond7casino.com | Active | Not yet covered |
Eleven further domains on the same account are marked Inactive, which means the licence once covered them and no longer does. They include Karamba, Hopa, Jonny Jackpot, CasiGO, Captain Spins, Griffon Casino, Reel Island and BetTarget. Several of those brands still trade elsewhere, so an Inactive line on this account is a statement about this licence and not a statement that a site has closed.
What the Gambling Commission register actually lists
White Hat Gaming Limited holds account number 52894 with a head office address given as Cornerstone Business Centre, Mosta, MST 1180, Malta. The single operating licence on the account is 052894-R-329546-008. It has been Active since 29 October 2018 and is shown as current, and it covers five remote activities: bingo, casino, gambling software, and general betting on both real and virtual events.
Only one trading name is registered against the account, which is white hat gaming itself. The footer of Mainstage Bingo adds the company detail: White Hat Gaming Limited is registered in Malta under number C73232 with a registered office at 85 St John Street, Valletta, VLT 1165, and it also holds Malta Gaming Authority licence MGA/B2C/370/2017, issued on 1 August 2018, for players outside Great Britain.
Own brands and white label sites are not the same thing
The largest group on account 52894 is neither Active nor Inactive. Twenty one domains carry the status White Label, and that is a different relationship. A white label site runs on the White Hat Gaming platform and under the White Hat Gaming licence, but it is marketed and owned by another business. Casimba, Casilando, Dream Vegas, Grand Ivy, Jackpot Village, PlayGrand, Playzee, Slot Planet, Spinland, Spin Station, Barz, Temple Nile, Miami Dice, 21 Casino, 247Bet, Blackjack City, Casiku, Mr Ben, Mr Run, Spin Rider and SpinYoo all appear that way.
That distinction matters when you are hunting for sister sites. A white label brand such as Casimba or Playzee shares a platform, a licence and often a games lobby with Mainstage Bingo, so bonuses, banking and verification will feel familiar. It does not share an owner. Our wider White Hat Gaming casinos page takes the platform side of that story further.
Mainstage Bingo questions
Who owns Mainstage Bingo?
White Hat Gaming Limited, a Malta company registered under number C73232. It holds Gambling Commission account 52894 and licence 052894-R-329546-008, active since 29 October 2018.
How many Mainstage Bingo sister sites are there?
Six, if you count only the domains marked Active on the same licence account. They are G Day Casino, Hello Casino, Skol Casino, Slotnite, 21 Prive and Diamond 7 Casino.
Is Casimba a Mainstage Bingo sister site?
Not in the ownership sense. Casimba is listed on account 52894 as White Label, so it uses the same licence and platform but belongs to a different company.
Is Mainstage Bingo licensed in the UK?
Yes. Our check of the Gambling Commission register on 7 September 2026 found www.mainstagebingo.com listed as an Active domain on account 52894.
Is Karamba still a Mainstage Bingo sister site?
Not on this licence. Karamba appears on account 52894 with the status Inactive, so it is a former stablemate rather than a current one.
