Sister Sites: What They Share and What They Do Not

Sister sites are brands operated by the same licensee. They typically share a platform, a compliance team and a set of terms, while running different promotions and designs.

What is usually shared: the licence, the responsible gambling framework, self-exclusion across the group, anti-fraud rules, and often the same withdrawal processing team.

What is usually not shared: welcome offers, loyalty schemes and game lobbies, which are configured per brand.

The important implication is on bonus abuse rules. Claiming a welcome offer on several sister sites can breach the one-per-household or one-per-group condition and lead to confiscated bonus winnings, even though each site looked independent.
