Two free interactive maps I build on Wikidata, castles and filming locations. The games came after, just for fun, because the data was already there.

Guess the Castle https://thecastlemap.com/guess/ A photo a day out of the 500 most famous castles. Six guesses, distance and direction after each miss. Also an endless mode where the user can play for ever for all 6,412 landmarks.

Guess the Location https://thefilmmap.com/guess/ A film, series, game or anime a day. Tap where you think it was shot. Six guesses, 13,097 real locations on the board.

It is free to use, no sign up required and naturally no ads. Every answer is a Wikidata record, so you can check it. Happy to take corrections and feedback.
