Gday Casino Sister Sites: White Hat Gaming’s Other Brands
Gday Casino sister sites include Gate 777, Diamond 7 Casino, 21 Casino and Casino Joy, all of which have run on the same White Hat Gaming platform. They share the operator White Hat Gaming Limited and its UK Gambling Commission account 39175; what they do not share is the Aussie theme that gave Gday its name.
Gday Casino Sister Sites and the White Hat Gaming Network
Reviewed by Emma JenkinsPublished: Jan 2019 · Last updated: June 2026
Gday leaned on an outback, big-friendly-welcome identity. Strip that branding away and you are left with a fairly standard White Hat Gaming casino: the same back office, the same provider feeds and the same UK licence that powered a string of related brands. That is the honest reason these casinos are called sisters.
A note on the term: some people reserve the label for regional copies of one casino. We follow UK search habits instead, counting any casinos that share an owner or a licence. Here the tie is White Hat Gaming Limited, holding UKGC account 39175.
Best Gday Casino Sister Sites at a Glance
- Closest in feel: Diamond 7 Casino, another classic slots-first White Hat brand.
- Still worth checking is live: 21 Casino, the longest-running name in this group.
- For table-game players: Casino Joy, before it wound down, led on live dealer rooms.
- Aviation twist on the same platform: Gate 777.
Gday Casino Sister Sites Compared
| Sister site | Status now | UK licence | Best for | Welcome offer | Vs Gday |
|---|---|---|---|---|---|
| Gate 777 | Retired | WHG, 39175 | Themed slots | Offer withdrawn | Travel theme, same engine |
| Diamond 7 Casino | Retired | WHG, 39175 | Jackpot slots | Offer withdrawn | No outback styling, same library |
| 21 Casino | Active, please verify | WHG, 39175 | All-rounder | Match plus spins, check terms | Broader and still trading |
| Casino Joy | Retired | WHG, 39175 | Live tables | Offer withdrawn | Stronger live rooms when open |
The Sister Brands in Detail
Gate 777. A 1920s aviation theme bolted onto the standard White Hat slot catalogue. Same NetEnt, Play’n GO and Microgaming feeds Gday carried. Against Gday it was glossier to look at but functionally close. It has since been retired.
Diamond 7 Casino. The most slots-led name in the family, big on jackpot titles and quick-play reels. If you liked Gday for the games rather than the kangaroos, Diamond 7 was the nearest swap. It is also no longer open.
21 Casino. The veteran of the group and the one most likely to still be trading. Wider game mix, recognisable name, fewer gimmicks. If you want a live White Hat casino rather than a closed one, start your checks here.
Casino Joy. Pitched at live-dealer fans with a colourful, upbeat front end. It offered stronger table rooms than Gday but has been wound down along with several siblings.
The Complete White Hat Gaming List
Beyond the four above, White Hat Gaming has run or powered many casinos. Owned brands over the years include Slots Cafe, Mainstage Bingo, Gold Spins, Deal Or No Deal Bingo and Fruity Casa. Shuttered names include Sloty, Casino Cruise and Spinit. The company also runs a white-label platform, so various casinos elsewhere use its technology under their own brands. Old affiliate pages still list sites that have shut, so treat any roll-call as a snapshot and look a casino up on the public register before you pay in.
What Is the Same and What Differs
| Feature | Gday Casino | The sisters |
|---|---|---|
| Operator | White Hat Gaming Limited | The very same company |
| UK licence | UKGC account 39175 | Run under that account |
| GamStop | Covered while live | Covered too, as UKGC brands |
| Theme | Australian outback | Aviation, jewels, live tables, vary |
| Game feeds | NetEnt, Play’n GO, Microgaming | Largely overlapping |
Are These Official Gday Casino Sister Sites?
Three things get muddled here. First, the company family: casinos that share White Hat Gaming and licence 39175, which is what this page lists. Second, regional “official Gday” editions, which never existed. Third, unrelated outback-themed casinos that simply borrowed the idea. Only the first is a real sister.
Gday Casino Review
Gday Casino opened as a cheerful, Australia-themed slots site on the White Hat Gaming platform. The best information available indicates it has since been retired and is no longer taking UK players, so this review is informational rather than a recommendation. If you hold an old balance, withdraw it and keep your account emails.
Welcome Offer and Promotions
While live, Gday ran a deposit match with bonus spins, refreshed by midweek and weekend reloads. Those promotions have been withdrawn. We do not list a current offer because there is not one to stand behind.
Games and Providers
The library was slots-first: NetEnt, Play’n GO, Microgaming and a rotating set of jackpot titles, plus a small live-casino tab. It was a solid mid-size catalogue rather than a giant one.
Payments and Withdrawals
Funding ran on debit cards, e-wallets and direct bank payments, all in sterling. A one-off identity check sat before the first cashout, the standard Commission checkpoint rather than a Gday peculiarity.
Support, Mobile and Responsible Gambling
Live chat and email handled questions, and the casino ran in a browser with no standalone app. Spend caps, time-out reminders and self-exclusion were on hand, all under the GamStop scheme. Away from the site, BeGambleAware, Gambling Therapy and GamCare are the independent bodies worth noting.

Our Verdict on Gday Casino
Gday Casino was a likeable, well-licensed slots brand whose main flaw now is that it appears to be closed. We would not point a new player at a retired casino, so the practical advice is simple: of its White Hat siblings, 21 Casino is the one to check first, and only after you confirm it is live on the UKGC register. As a live recommendation Gday earns a low score; as a piece of the network history it is still worth understanding.
