As Tim Preston, publishing director of Puzzler Media, Britain's biggest seller of crossword and cryptogram puzzles, has "It is a matter of great pride to get your puzzle into one of Nikoli's magazines. Handmade puzzles are much better. . . .

One of the best sudoku puzzle collection I've ever completed.
November 26, 2010
Not a review so much as random notes.
Bought this for $1 at a secondhand shop and it was the best $1 I spent in the last few years.
I worked on these in my spare time over about a year and a half.
puzzle 36: I noticed that all the puzzles started with the clues filled in in a symmetrical pattern, whether horizontal, vertical, diagonal, or rotational symmetry.
puzzle 92: I worked on this one for days, then realized that the puzzles had gotten complex enough that I couldn't hold all possible values in my head, so I had to start using a notational system to mark possible values of a given cell. Then, erasing values as they were no longer possible, it got much easier to solve puzzles.
puzzle 240: I noticed that the images at bottom left made a flip cartoon.
The puzzles in this book are both clever and aesthetically pleasing, some of them downright elegant.
