Bought this for a long flight with my 8-year-old and it kept her busy for almost two hours. The 18 puzzles build on each other nicely, and she loved turning the wheel to crack each code before flipping to the next mystery.

The decoder wheel actually works, which kept my daughter busy for the whole flight. Eighteen pages of codes and whodunits sounds short, but each puzzle takes real thinking. Best $8 I've spent on a travel distraction.

My 8-year-old nephew barely looked up from the decoder wheel during our whole road trip—18 pages was just enough to last until we hit the hotel. The whodunit puzzles are clever without being frustrating, and he loved flipping the page to find a completely new code to crack.
