Doctor Ecco's Cyberpuzzles

As a fan of Ecco's Puzzling Adventures, I was eager to take a look at his cyberpuzzles. Ecco and his protege Shasha have done it again, and I recommend this book to anyone looking for interesting, challenging, thoughtful problems.The book is a fun and intersting read on its own, but I have also drawn on the book's puzzles in teaching (a course on logic and discrete math).It's very cool to have a book that can entertain and educate at the same time! Looking forward to Ecco's further adventures.
