Yeah, that's pretty much it. GeoGuessr puts you in random locations (Google street views). You can wander around and find street signs to help guess. That's where seeing the Finnish Dash Acad has helped. There are patterns like: double dots over 'a' and lots of double letters 'aa' 'kk'. Sweden is similar but they don't nearly have as many 'k's or 'i's in their signs.
