Boomerang Casino review: blocks the UK, never UK licensed

Boomerang Casino is not closed, but you cannot play it from the UK. On 7 September 2026 boomerang-casino.com answered our UK request with an HTTP 403 and a one line notice: “This internet site is not accepting visitors from your country”. It has never held a Gambling Commission licence, so there was never a UK licence to lose. For a UK player the practical answer is that the site is off limits, and it was never a legal option here in the first place. Our score: 5.5 out of 10.

That is half a point above what we give offshore sites that let British players in, for one reason: Boomerang keeps the door shut.

Boomerang Casino at a glance

Nothing on the register

We searched the Gambling Commission register for “boomerang casino”, “Rabidi” and “Araxio”. The only results were Boomerang Studios, a games supplier, and Boomerang Digital, which is unrelated. No casino operator called Boomerang has ever appeared, and neither Rabidi nor Araxio has an entry. That rules out a current licence and a lapsed one. Our UKGC licensing guide explains how to run the same search and what a genuine entry shows.

Who runs it

Boomerang is a Rabidi N.V. group brand. Two third party sources, rabidiexposed.com and epoca.ro, say the group renamed itself Adonio N.V. and that its Antillephone licence claim, number 8048/JAZ, was reported terminated in October 2025. The same sources point to Stellar Ltd and an Anjouan licence as the current arrangement.

We could not verify any of that ourselves. The site blocks the UK, so we cannot read its footer, its terms or its licence seal from here. Treat the Adonio and Anjouan details as reported rather than confirmed. We would rather say that plainly than repeat a claim we cannot check.

What we can say is that none of this touches the UK register. Whether the operator is trading as Rabidi, Adonio or Stellar, and whether its licence comes from Antillephone or from Anjouan, makes no difference to a UK player: Boomerang has no UK entry, so there is no UK complaint route and no GAMSTOP connection.

What a UK visitor sees

The full text of the block page is: “Forbidden This internet site is not accepting visitors from your country. Should you have questions please contact us at support@boomerang-casino.com”. There is no lobby behind it and no sign up form.

Wayback’s copies of the domain have alternated between 200 and 403 responses since 2021, which is what you would expect from a site that decides what to show based on the visitor’s country. It also tells us the block is not new. Our Donbet and Goldenbet reviews cover two other sites that treat UK visitors the same way.

Trustpilot: 3.4 from 825 reviews

Trustpilot rates boomerang-casino.com at 3.4 from 825 reviews, captured on 7 September 2026. 37 per cent are one star. The operator replies to 89 per cent of negative reviews and the profile shows it invites reviews. The newest review is dated 2 September 2026, so the site is still trading somewhere.

A 3.4 is middling rather than bad, and the invited reviews will have helped it along. We would not read much into the score either way. Whatever the experience is like for a player in another country, a UK player cannot get in to find out.

Why the block is the better outcome

It sounds odd to give a site half a point for refusing to serve you, but the alternative is worse. An offshore casino that lets UK players in without a UK licence exposes them to terms nobody in Britain regulates and lets self excluded players past GAMSTOP. Boomerang does neither, because it does not let UK players in at all. That is the whole basis for the 5.5 rather than a 5.

We are not able to score the games, the payments or the support desk from anything we have seen ourselves. Everything a customer would use sits behind the block, and the only support contact we know of is the email on the Forbidden page. Our sub scores for those areas sit at the bottom of the scale for that reason, not because we found something wrong with them.

Casinos without a British licence take different approaches to UK visitors, and the block is often the safer outcome. Compare Casinia, which blocks UK visitors and sits in the same Rabidi group as Boomerang, Tsars, which blocks the UK while a separate site quotes a licence number that does not exist and Loki Casino, which takes UK visitors with no British licence and no named company.

What to do if you had an account

If you opened a Boomerang account in the past, perhaps from abroad, and still have a balance, the only contact route we can see is the email address on the block page, support@boomerang-casino.com. Write to it, ask for a withdrawal and keep a copy of the thread. There is no UK regulator and no UK dispute service to escalate to, because the site was never licensed here.

Do not use a VPN to get round the block. You would be playing on a site with no UK oversight, under terms you cannot read from the UK, with a licence status that third parties say changed in October 2025 and that we cannot confirm. If you are self excluded through GAMSTOP, note that Boomerang is not part of it; the geo block, not GAMSTOP, is what keeps you out, and a VPN removes it. If you want the protections a UK licence brings, pick a brand that is on the register today.
