Editorial Policy

Every guide on All Sister Sites answers one question: which casinos genuinely belong to the same family, and what should a player know before choosing between them. This page explains how we work.

How pages are researched

Ownership and licence claims are checked against primary sources wherever possible: the UK Gambling Commission public register, the Malta Gaming Authority register, operator corporate sites and, for closed brands, web archives. Where a fact cannot be verified first-hand we say so in the text rather than presenting a guess as certainty. You will see phrasing like “review databases credit…” on pages where the primary record is unclear — that hedging is deliberate.

How pages are updated

Casino families change constantly: brands close, licences are surrendered, operators sell up. Our guides carry a visible re-check note or updated date when they have been re-verified, and our highest-traffic pages sit in a rolling weekly re-verification cycle. The Quick facts box on brand pages shows the date a page’s facts were last reviewed.

Corrections

When we get something wrong we correct the page and, where the error was material, say what changed and why. Several pages on this site carry a “Why this page was corrected” section for exactly that reason. If you spot an error, use the contact page and we will check it against the primary records.

What we do not do

We do not copy other sites’ brand lists, we do not present affiliate deals as rankings, and we do not keep dead casinos listed as live to hold onto a page. Closed brands are marked closed, with a plain explanation of what happened.
