Rainbet Sister Sites: What Is Actually Confirmed?

Rainbet sister sites are not currently confirmed by the public corporate and operator evidence I checked. I found no second gambling brand that I could verify as being operated by Rain Group Ltd on the evidence available for this guide, sharing a publicly documented parent company with Rainbet, or linked to Rainbet through documented common ownership.

That is not the same as claiming that no undisclosed relationship could exist. The evidence only supports a narrower conclusion: I could not verify another current sister brand from the public sources available. Rainbet Splash, despite the similar name, is not a verified Rainbet sister site.

The sister-brand assessment recorded on 22 September 2026 did not establish a verified sister brand. The legal and licence material checked then named RBGAMING N.V. The operator disclosure is now different: Rainbet's Terms and AML policy checked on 29 October 2026 name Rain Group Ltd, registration number 16077 in Anjouan. That disclosure does not itself establish a new sister-site relationship.

The public material checked did not establish a second gambling brand under the same current operator, a disclosed parent company linking Rainbet to another brand, or a publicly established common shareholder or beneficial owner. The public sources I checked do not identify a parent company, common shareholder or ultimate beneficial owner that links Rainbet to another gambling brand, so I stop short of the stronger claim that no undisclosed sister relationship can exist.

Operator and ownership evidence are what establish a sister-site relationship, not branding or product similarity. For the broader company background, see Rainbet ownership and operator details.

Another casino should only be described as a Rainbet sister site when current evidence shows a real corporate relationship. That could mean the same legal operator, the same disclosed parent company, publicly established common ownership, or another directly documented corporate link.

A similar name is not enough. Neither are shared game providers, crypto or payment options, similar software, comparable bonuses, the same licensing jurisdiction, similar design, or inclusion on an affiliate list. Those details may show that two casinos resemble each other, but they do not prove that the businesses are related.

The distinction matters because operator, parent-company and ownership links can change over time. Historic or undated material should not be used to describe a relationship as current without supporting evidence. Older Rainbet legal wording also does not, by itself, prove that another named casino was historically part of the same group.

I checked Rainbet Splash separately because its name can easily suggest a connection. The current evidence points to a different operator.

Rainbet's Terms and AML checked on 29 October 2026 name Rain Group Ltd. The UK Gambling Commission domain record checked on 22 September 2026 for rainbetsplash.com lists ProgressPlay Limited under account 39335 and classifies the domain as a White Label.

I found no current evidence establishing the same operator, parent company, shareholder, beneficial owner or corporate group between Rainbet and Rainbet Splash. On the evidence available, its status is therefore NOT A SISTER SITE / SIMILARITY ONLY.

ProgressPlay operates other domains, but those brands sit within ProgressPlay's operator network, not a verified Rainbet group. They should not be presented as Rainbet sister sites.

A sister site and a similar casino are different things. If you are looking for casinos with comparable products or features rather than a verified corporate relationship, see the separate guide to similar casino options and alternatives to compare. Keeping the two questions separate avoids mistaking resemblance for common ownership.
