Our first book devoted entirely to one hundred of our largest and most fiendishly difficult logic puzzles! One hundred grid-based logic puzzles are provided, all of them requiring multiple advanced solving methods. Average solve times and completion rates are provided to give you a real-world idea of how challenging each puzzle actually is.
Available at Amazon.comThese are GREAT puzzles. Some I can complete by methodically working away on the clues (going through them once, then going through them again). Others are more maddening, but can be solved in the end. Definitely a challenge, and that's what I was looking for. PUBLISH ANOTHER SOON PLEASE!

I love logic puzzles, and this is the best book I've found for them. I loved this book so much that I actually bought another copy after leaving my first one on vacation. — Laura B (Amazon.com)
I am addicted to these puzzles! This book with 100 puzzles will keep me busy for awhile -- and then I will hope there is a Fiendish Puzzles 2! — Katharine M (Amazon.com)
