Diamond 7 Casino Sister Sites and Where the Network Stands
Reviewed by Emma JenkinsPublished: Feb 2022 · Last updated: June 2026
Diamond 7 was a no-nonsense slots casino: bright jewel branding, a wall of reels and not much else competing for attention. Behind that front sat the standard White Hat Gaming setup, which is what ties it to the brands below.
On terminology: we treat related casinos as those sharing a parent business or a Commission permit, which matches how the phrase is searched here. Diamond 7 belonged to White Hat Gaming Limited, UKGC 39175.
Diamond 7 Casino Sisters at a Glance
- Most alike: Fruity Casa, another slots-led classic from the same era.
- Best chance of still being live: 21 Casino.
- For a more premium look: Grand Ivy leaned upmarket.
- Themed sibling: Gate 777 and its aviation styling.
Diamond 7 Casino Sisters Compared
| Casino | Live? | UK licence | Suited to | Bonus | Difference from Diamond 7 |
|---|---|---|---|---|---|
| Fruity Casa | Retired | Under WHG 39175 | Pub-style slots | Withdrawn | Fruit-machine theme, same core |
| Gate 777 | Retired | Under WHG 39175 | Themed reels | Withdrawn | Travel styling, similar games |
| Grand Ivy | Unconfirmed | Under WHG 39175 | Premium feel | Check on site | Smarter design, table focus |
| 21 Casino | Active, verify | Under WHG 39175 | All-rounder | Match and spins, terms apply | Broader and still trading |
Each Sister, Briefly
Fruity Casa. The closest match in spirit. A fruit-machine theme over the same White Hat slot feeds Diamond 7 used, with comparable jackpot titles. It has been retired, like Diamond 7 itself.
Gate 777. Swap jewels for a 1920s air-travel theme and you have Gate 777. The reel catalogue overlapped heavily. Now closed.
Grand Ivy. The dressier sibling, with a more refined layout and a stronger lean towards table games. If Diamond 7 felt basic, Grand Ivy was the polished version on the same licence.
21 Casino. The long-runner and the safest bet for finding a White Hat casino that is still open. Wider mix, established name. Confirm it is live before depositing.
The Complete White Hat Gaming Slots List
The casino side has featured a run of reels-led brands: Diamond 7, Fruity Casa, Gate 777 and Gday Casino, most now shut, next to newer sites like Slots Cafe and Gold Spins and the wider 21 Casino and Grand Ivy. Bingo sits under Mainstage Bingo and Deal Or No Deal Bingo, and a white-label arm powers other firms. Many of the older casinos have gone, so any list is a moment in time; confirm a casino is still listed by the Commission before trusting it.
Shared Wiring, Different Skins
| Feature | Diamond 7 Casino | The related brands |
|---|---|---|
| Operator | White Hat Gaming Limited | One and the same |
| UK account | 39175 | The same number |
| GamStop | Applied when open | Applies across them |
| Style | Jewels and sevens | Fruit, aviation, premium, vary |
| Slots source | Mainstream studios | Largely the same studios |
Are These Official Diamond 7 Casino Sister Sites?
Pull three categories apart. The casinos sharing the same owner and licence 39175 are the real answer, and they sit above. No “official Diamond 7” regional sites were ever launched. Other casinos trading on “diamond” or “777” names are coincidence, not kin. Sisterhood here is about the owner, nothing else.
Diamond 7 Casino Review
Diamond 7 Casino was a compact, slots-driven site on the White Hat Gaming platform. Everything points to the brand having been wound down, with no UK sign-ups on offer, so read what follows as a record of what it was rather than a prompt to join. Withdraw any old balance and keep your emails.
Welcome Offer
In its day Diamond 7 offered a first-deposit match with spins and a short ladder of reload deals. That offer is no longer available, and we will not quote a stale one.
Game Range and Studios
Almost entirely slots: NetEnt, Microgaming and Play’n GO reels with a jackpot shelf, plus a thin live tab. Players who wanted depth in table games tended to drift to siblings like Grand Ivy.
Banking
Deposits and withdrawals used cards, bank transfer and e-wallets in pounds. Identity cleared ahead of an opening payout, and e-wallet cashouts tended to land sooner than card refunds.
Support, Mobile and Player Safety
Support meant chat and email, with browser play and nothing to download. The brand offered limit-setting, reality prompts and self-exclusion, and registered with GamStop. Independent backup came from Gambling Therapy, BeGambleAware and GamCare.

Operator details last reviewed: June 2026 (last updated 9 June 2026)
Status reassessed: the casino appears to have been closed by the operator.
Pros and Cons
Pros: backed by a credible, UK-licensed operator; uncluttered slots-first design; mainstream studios on the reels; full GamStop and UKGC tooling when it was running.
Cons: the casino appears closed, so there is nothing to join now; bonus is gone; thin on table and live content; no app; if a brand is winding down, getting any leftover funds off the account quickly is the sensible move.

Our Verdict on Diamond 7 Casino
Diamond 7 did one thing, slots, and did it tidily, but a closed casino cannot be recommended to anyone today. The takeaway is about the network rather than the brand: if you liked Diamond 7’s simplicity, Fruity Casa was its twin and is also gone, so the realistic move is 21 Casino, checked first on the register. On current availability Diamond 7 scores low; as a reference point it still earns its place.
