An exceedingly well produced book! I have purchased and enjoyed the entire Sudoku series, and am now working my way through this Kakuro series. When one pays for published puzzles, as opposed to downloading free puzzles, one expects well crafted, single solution, enjoyable puzzles. Not only does this publication meet the mark, it does so on eye-friendly, pencil-friendly paper, with a comfortable-in-the-hand binding. Admittedly, I'm a paper snob. I dislike newsprint as it clogs erasers and is difficult to read in low lighting. Puzzlewright has met all my expectations and preferences with this book, in an affordable and pleasing format. Well done!
