GeoSapiens IGN

GeoSapiens is a free, open-source interactive map application from the Spanish National Geographic Institute (IGN) for studying physical and political geography of Spain and the world. It groups games by geographic area (Spain, autonomous communities, continents, world) and covers landscape, relief, rivers, coastal features, flags, lithospheric plates, countries and capitals, plus image-based "Where Am I?" challenges and a land change analysis mode.

Choose from multiple game modes — Show, Drag outline, Locate random, Locate all, Test and Customize — with selectable difficulty levels. The app is bilingual (Spanish/English), configurable (font size, sounds, avatar), mostly offline (some image-based modules require internet), and is an educational resource developed with CNIG, UPM and supported by FECYT, with photos from CENEAM and UNESCO.
