About the Author
Gould was a lawyer for 13 years in Matamata, New Zealand, before coming to Hong Kong in 1982 where he worked his way up to become Chief District Judge in 1993. He retired from the Judiciary in 1997 and, that same year, during a visit to Japan, he was in a bookstore where, not knowing how to read or speak Japanese, he was drawn to the puzzle which he first thought was a crossword. He was intrigued and later on he decided to take it with him to the United States and Britain. After his initial retirement, in efforts to pass time and sharpen his computer skills, Gould developed the computer program that generates Sudoku puzzles.

Customer Reviews

Most difficult Sudoku book I've tried, and probably the best!
Be very clear right from the start - this is not a sudoku book for the faint hearted! In fact, it is easily the most difficult - and therefore for me, the most satisfying I've tried.

I'd enjoyed (over a long period of time!) Gould's "Fiendish" books published under the Times banner but when I came to the end of that I was at a bit of a loss where to turn next. I tried the Tom Sheldon "Sudoku Genius" book which was difficult but annoyingly this documents and advocates a "trial and error" approach which to my mind is not true sudoku and the puzzles were greatly devalued as a result. I stopped after a dozen or so,

Due to the authors pedigree, the puzzles in here definitely have the right feel - no guessing required, but very very deep thought definitely is. Towards the end of his Times Fiendish Book I was getting great satisfaction in doing the puzzles without any pencil marks, i.e. purely by logic and brain power, but they would take me 30 odd minutes quite often

I have yet to be able to do a puzzle in this book in anything like that time, and certainly have not finished any without writing numbers in.

There is no messing about, it is straight in with the hardest level. The first one took me ages to complete until I got into the swing of it. I should also add that it is extremely worthwhile reading the advanced tutorials at the start, i finally understood the x-wing and swordfish methods which are essential for usage even after just the first few puzzles

If you like extremely difficult sudoku, are a fan of the Times puzzles and their associated logic, and most other books are either too easy or the puzzles aren't well formed, then trust me, you will LOVE this book.

I agree - Hardest yet!
I agree with the previous reviewer. I have tried and largely completed many other su doku titles, including the Fiendish/Super-Fiendish ones, but this is by far and away the most testing of the lot. So much so that I have already purchased Extreme #2 and #3, although it may be some time before I get to those ones!

Su Doku Extreme
Very good, again the title is correct. Gives you a challenge, unlike most books.
