The Cypher Files: An Escape Room… in a Book! by Dimitris Chassapakis

3.0

I've never tried anything like this. My wife and I gave it a go and enjoyed the puzzles. The book conveys an espionage mystery story through multiple pages of puzzles that require the use of your smartphone. The book also requires you to write in it and at times fold or cut the paper (my biggest hang-up and the reason for the lower score) to solve some puzzles.
