Gratowin Sister Sites: Two Names, One Casino, No Confirmed Siblings
Gratowin is a real, established casino, trading since 2019, but its operator identity is genuinely unsettled across the sources we checked. AskGamblers, the most directly verifiable source we could reach, names the operator as Filavuns LLC under a Kahnawake Gaming Commission licence. Other aggregators name a different company, Unigrad Trading N.V., and cite a Curacao licence number, 8048/JAZ, that we have already confirmed on another page this session ceased to exist in November 2024. We could not access Gratowin’s own terms and conditions directly, the site sits behind a Cloudflare challenge that blocks automated fetches, so we are reporting both claims rather than picking one.
Given that uncertainty, we are not naming any sister sites on this page. Some sources associate Gratowin loosely with brands like Gratorama, Winorama and Playoro, but without a confirmed operator we cannot independently verify that connection, so we would rather leave it out than repeat an unchecked claim.
Who Actually Runs Gratowin?
AskGamblers’ review lists the operator plainly as Filavuns LLC, licensed by the Kahnawake Gaming Commission, and describes the casino as established in 2019. That is a specific, directly-sourced claim from a major aggregator, and we are treating it as our primary reference point.
Separately, several other review sites describe Gratowin as operating under Unigrad Trading N.V. and a Curacao eGaming licence numbered 8048/JAZ. We have already documented, on our Slotrave review, that this exact licence number stopped being valid in November 2024, and that it continues to circulate on promotional and review pages regardless. Whether that reflects a genuine historical Curacao licence Gratowin once held, confusion with an unrelated brand, or simply outdated content being copied between review sites, we could not resolve with the sources available to us.
| Claim | Operator named | Licence claimed | Source type |
|---|---|---|---|
| Primary claim | Filavuns LLC | Kahnawake Gaming Commission | AskGamblers (directly fetched) |
| Alternate claim | Unigrad Trading N.V. | Curacao 8048/JAZ (expired Nov 2024) | Multiple review aggregators |
Gratowin Reviewed

Gratowin runs a broad games catalogue from more than 34 studios, including Evolution, NetEnt, Pragmatic Play, Play’n GO and Big Time Gaming, alongside a headline welcome package reported at up to $3,000 across the first three deposits, with 35x wagering, plus a 50 free spins no-deposit offer for new sign-ups. That is a large enough package that we would treat the wagering terms as the more important detail than the headline figure.
Access notice. AskGamblers’ own geo-detection flags Gratowin as restricted for UK visitors and surfaces licensed alternatives instead. Under either operator claim, Kahnawake or Curacao, there is no UK Gambling Commission recognition, so GamStop and IBAS do not apply.
Reputation: Decent Numbers, Very Thin Sample
AskGamblers gives Gratowin a CasinoRank Safety Index of 7.1 out of 10 and a player rating of 8 out of 10, though that rating rests on a single review, far too small a sample to treat as settled. No blacklist listing exists on AskGamblers, and we found no LCB review at all, this brand simply has not accumulated the volume of independent scrutiny that some sister brands on this site have.

Strengths and Weaknesses
Strengths
- Established, multi-year trading history rather than a brand-new launch.
- Broad software catalogue from well-known studios.
- Not blacklisted, with a reasonable AskGamblers Safety Index.
Weaknesses
- Genuinely unresolved operator identity across major review sources.
- A stale, expired Curacao licence reference still circulating in secondary sources.
- No UK Gambling Commission recognition under either claimed operator.
- Very thin independent review volume behind its headline scores.
UKGC-Licensed Casinos With One Clear Operator
A casino whose own operator name is disputed across major review sites is a harder brand to trust than one with a single, checkable identity. Names such as Casumo, PlayOJO, LeoVegas and Mr Q don’t come with that problem, each has exactly one named operator sitting on the Gambling Commission’s public register, with GamStop coverage and IBAS access built into the licence itself.
Gratowin: Common Questions
Who owns Gratowin?
AskGamblers names Filavuns LLC under a Kahnawake licence. Other review sites name a different company, Unigrad Trading N.V., under a Curacao licence number that has since expired. We could not resolve which is currently accurate.
What are Gratowin’s sister sites?
We are not naming any. With the operator identity itself unresolved, we cannot independently confirm any sister-site relationship.
Does Gratowin accept UK players?
AskGamblers’ geo-detection flags it as restricted for UK visitors, and no UK Gambling Commission licence applies under either operator claim.
What licence does Gratowin hold?
This is disputed. AskGamblers cites a Kahnawake Gaming Commission licence; other sources cite a Curacao licence number that expired in November 2024.
Is Gratowin safe to play at?
AskGamblers rates it 7.1 out of 10 with no blacklist listing, but that sits on a very small review sample, too thin to call the picture settled.
What games does Gratowin offer?
More than 34 providers including Evolution, NetEnt, Pragmatic Play, Play’n GO and Big Time Gaming.
Which licensed casinos don’t come with an ownership question mark?
Casumo, PlayOJO, LeoVegas and Mr Q each have a single, publicly listed UK Gambling Commission operator, with GamStop and IBAS available as a matter of course.
Our Take on Gratowin
Gratowin is a real, multi-year casino with a broad games catalogue and a reasonable AskGamblers score, but the most honest thing we can say about its ownership is that we do not fully know who runs it. Two credible-looking sources name two different companies under two different regulators, and one of those regulator claims rests on a licence number we have already confirmed is expired elsewhere on this site. That is not proof of anything sinister, but it is exactly the kind of basic uncertainty that should give a cautious player pause, and it is why we are not naming any sister sites here despite some looser claims elsewhere online. For a UK reader, it barely matters which version turns out to be accurate: neither company has ever sought UK approval, so the sensible move is to skip the guessing game and pick a casino where that question never comes up in the first place.
