Geo-Blocking

Geo-blocking is the foundational tool for license compliance in regulated markets. An operator licensed in Spain must geo-block players outside Spain on their Spanish-licensed entity; an operator with no UK license must geo-block UK players from any product that would otherwise serve them; US sports betting operators must geo-block across state lines to operate only in licensed states. The combination of IP-based blocking, device geolocation, and payment-method validation handles most legitimate use cases. Sophisticated geo-blocking is harder than it looks. Players using VPNs can spoof IP location; mobile geolocation can be unreliable at state borders; players changing residence during a session create edge cases. US sports betting operators in particular have invested heavily in geo-fencing technology (GeoComply being the dominant vendor) because state-line accuracy is a regulatory requirement and breaches are enforcement matters. The "Tribal versus commercial gaming on tribal land" boundary in US states with both adds another geo-fencing dimension.
