This book is very aptly named. The puzzles are, in fact, fiendishly difficult to solve. This is at least partly due to the author’s ability to create a puzzle and the variety that she finds within each type. This book includes crosswords, word searches, sudoku, calcudoku, kakuro and cryptograms. In each category, Ms. Chen has created variations on a theme. For example, the first word search puzzle is difficult but traditional. Following this one though, the others all have a twist; for instance the next puzzle has anagrams and the one after that is called change the first letter. Similarly most of the puzzles in the book have a twist that makes them quite challenging.
This book will be welcomed by those who want to immerse themselves in a challenge that could well take time. Beginning puzzlers may be frustrated by the book. Think about who you are and then decide.
