The ultimate Su Doku challenge from Wayne Gould, the world's best-selling Su Doku master. Wayne Gould is widely recognised as the leading authority on Su Doku books and has sold over 6 million Su Doku titles world wide. Such is his su doku gravitas that Time Magazine named him as one of the 100 people who shaped the world in 2005. In Extreme Su Doku Gift Set Wayne Gould presents the perfect gift for every su doku enthusiast: this elegant slipcase containing all three books offers a rich collection of 360 super-fiendish puzzles and is set to take the reader to a new exhilarating level.
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.
