21 Casino is part of the White Hat Gaming Limited network in Great Britain. Current brands connected through the same UK operator include 21Prive, Dream Vegas, Hello Casino, Grand Ivy, Casimba, Slot Planet, PlayGrand, Playzee, Jackpot Village, Miami Dice and Blackjack City.
The current UK Gambling Commission record for White Hat Gaming lists 21casino.com alongside these and other active White Hat domains.
If you are comparing operators rather than just casino names, our UK Betting Sister Sites directory covers more verified brand networks.
White Hat Gaming operates a fairly large network, so 21 Casino has more connections than many smaller UK casinos.
Some of the most relevant current brands are:
| Brand | Main focus | Connection |
|---|---|---|
| 21Prive | Casino | Same White Hat operator |
| Dream Vegas | Casino & slots | Same operator |
| Hello Casino | Casino | Same operator |
| Grand Ivy | Casino | Same operator |
| Casimba | Casino | Same operator |
| Slot Planet | Casino & slots | Same operator |
| PlayGrand | Casino | Same operator |
| Playzee | Casino | Same operator |
| Jackpot Village | Casino | Same operator |
| Miami Dice | Casino | Same operator |
| Blackjack City | Casino | Same operator |
| 247Bet | Betting & casino | Same operator |
For someone looking specifically for another casino, 21Prive, Dream Vegas, Hello Casino, Grand Ivy and Casimba are among the closest options.
21Prive is one of the clearest current connections.
It appears under the same White Hat Gaming licence as 21 Casino. Despite the similar “21” branding, the two operate as separate websites with their own registrations and promotions.
Dream Vegas is another current casino-focused White Hat brand.
It is particularly relevant to users looking for slots and casino games rather than sports betting.
Dream Vegas also appears as a separate future sister-sites topic in our research, so there is no need to repeat its entire network here.
Hello Casino and Casimba are both current White Hat Gaming brands.
They may look and market themselves differently from 21 Casino, but their operator connection is stronger evidence of a sister-site relationship than simply sharing games or software suppliers.
This is an easy one to mix up.
Grand Ivy is currently listed under White Hat Gaming and is therefore connected to 21 Casino.
Ivy Casino is a separate brand operating within a different UK network.
So although their names sound similar:
Grand Ivy ≠ Ivy Casino
Only Grand Ivy belongs in the current 21 Casino sister-site network.
There is an even more important naming distinction.
21 Casino uses 21casino.com and operates through White Hat Gaming Limited.
21.co.uk is a completely different casino. Its current terms and conditions identify LeoVegas Gaming PLC as the operator.
That means:
21casino.com → White Hat Gaming
21.co.uk → LeoVegas Gaming PLC
The similar names do not make them sister sites.
This distinction is particularly useful because searches for “21 Casino sister sites” can produce results referring to both brands.
21 Casino operates in Great Britain through White Hat Gaming Limited, UKGC account 52894.
White Hat runs a mixture of its own active domains and white-label brands.
The current UKGC record includes names such as 21Prive, Hello Casino, Diamond7 Casino and Mainstage Bingo alongside white-label domains including 21 Casino, Dream Vegas, Casimba, Grand Ivy and Playzee.
This means it is more accurate to describe the brands as part of the same White Hat Gaming operator network rather than assuming every site has identical ownership behind the scenes.
The White Hat network has changed over time.
Several domains that were once connected to the operator are now marked inactive by the UKGC, including:
They may still appear on older 21 Casino sister-site pages, but they should not be mixed into a list of current active options.
This is why checking the present UKGC domain record is more useful than copying an old operator list.
No shared account should be assumed.
Brands operating under the same White Hat licence can still have separate:
The operator relationship tells us why the sites are connected. It does not mean one 21 Casino login automatically works across the rest of the network.
Current connected brands include 21Prive, Dream Vegas, Hello Casino, Grand Ivy, Casimba, Slot Planet, PlayGrand, Playzee, Jackpot Village, Miami Dice and Blackjack City.
21 Casino operates in Great Britain through White Hat Gaming Limited under UKGC account 52894.
Yes. Dream Vegas currently appears under the same White Hat Gaming UK operator as 21 Casino.
No. 21.co.uk is operated by LeoVegas Gaming PLC, while 21casino.com belongs to the White Hat Gaming network.
Yes. Grand Ivy and 21 Casino both currently appear under White Hat Gaming.
Not through the current White Hat Gaming network. Ivy Casino belongs to a different operator group and should not be confused with Grand Ivy.
Not necessarily. Several former White Hat domains are now marked inactive, so older sister-site lists can contain brands that are no longer current.
21 Casino belongs to a large White Hat Gaming network, but users do not need a list of every domain to find the most relevant alternatives.
For casino players, 21Prive, Dream Vegas, Hello Casino, Grand Ivy, Casimba, Slot Planet and PlayGrand are among the most useful current connections.
The two biggest points to remember are that 21 Casino is not 21.co.uk, and Grand Ivy is not Ivy Casino. Checking the current licensed operator makes those relationships much clearer.
