I had bought a similar one in another city and liked it better as clues. The kids had fun, although some puzzles were calibrated to a more adult audience. You would need more balance in riddles, doing them either within everyone's reach or just for families. The ideal would be to be able to choose the level at the beginning of "game".

A fun and different way to spend a day, nice way to get to know the city. We have visited very nice places

I participated in the 'Zagreb Treasure Hunt and Self-Guided Highlights Tour', and it was an original and fun experience. After downloading the World City Trail app, I was able to follow a path of puzzles and riddles that guide through the most important points of the city, while describing history and curiosities that often escape traditional tours. The app is easy to use, the clues are well built (though sometimes not super intuitive, but thank goodness there were helpers available!) and allow you to discover both iconic places and lesser known corners of Zagreb. It is an interactive and engaging way to visit the city, suitable for both couples and groups of friends. I recommend this activity to anyone who wants to get to know Zagreb differently, having fun and learning at the same time!

fantastic app to explore the city and you immediately get a clear picture of its history. If you don't know a city, this is a fun way.
