What the shared licence actually means
A sister site is not a marketing label. Slot Boss and the 2 brands above are operated by the same company on the same Gambling Commission account, which is a matter of public record rather than opinion.
In practice one company is accountable for all of them: the same complaints and ADR route, the same licence conditions, and usually a shared platform, so game libraries and terms tend to overlap. It does not guarantee a shared wallet or shared bonus eligibility — those are set per brand, and many operators run one welcome offer per customer across the group.
One thing that is guaranteed: because every brand here holds a current Gambling Commission licence, a GAMSTOP self-exclusion blocks all of them at once, along with every other UK-licensed site.
