Title: All expert puzzles
Review: My book had all expert puzzles although it had labels for beginner to expert. I don't know if I got a different edition but I have done Sudoku puzzles online which are far easier than the so called beginner ones in this book. The first ones are the same difficulty as the final ones. When you average 27 given numbers in the beginner section and also the expert section, you know someone made a mistake when they printed the book or did their program to create the puzzles. If you are already an expert, this is good for working the puzzles. If you are a beginner, you will likely get very discouraged. You can use the helps in the beginning and create some of your own to be able to work the puzzles.
