This is a place to remember Solve-it-Yourself Puzzle books - both classic and modern. Welcome!
Minute Mysteries, Visual puzzles, Armchair Treasure Hunts, and Immersive Puzzles.
If it involves puzzles combined with a narrative of some kind, it's here!
Non-narrative puzzles, mazes, straightforward seek-and-find and 'Choose Your Own Adventure' gamebooks are not included (but there are many other useful online resources for those genres!).
Drop me a line!
