This is a nice little book. I don't think there is anything here that can't be found on the Internet, but at the time that wasn't the case. I picked this up in order to teach my puzzle classes for KOGMA and in my regular education class too.
It is a well put together book with an overview of some of the more common cryptography puzzles. I should have used this to create geocaching puzzles. Hmmm . . .

Fun for kids. A general over view but nothing specific.
