Why don’t more New Zealanders know about you?
Well, it’s one of those things. I enjoyed quite a bit of fame when Sudoku broke back in the world. And that was all very nice for a short while - for a couple of years, but beyond that puzzles speak for themselves I suppose. The kind of thing I had was the nicest possible thing I suppose, I had fame when I wanted it, but I could walk down the street and nobody knew who I am and nobody knows who I am even now.
Did you always love puzzles growing up?
Oh yes. Very definitely – games and puzzles. I was the youngest child of three by quite a margin and so in a way, I was an only child. And puzzles are games of a kind that you don’t need two or three or four other people to play with you. So puzzles became an interest of mine – crossword puzzles principally. But then I got involved in things like cryptanalysis – which was the fancy name for code-breaking and that in time led to coding of computers or programming.
Have you thought about what the appeal of puzzles is to humans?
Well, it’s a challenge. Mind you, it's a challenge where it doesn’t really matter if you don succeed and that I think is the most enjoyable thing. The most enjoyable thing about puzzles is that they have to be fun. It’s when games get too serious that I start switching out. So to me, a game and puzzle should be a way of enjoying some time – relaxation in a way.
When did you come across Sudoku for the first time?
Well, it was [in] 1997 and I was in Tokyo on holiday and I was just browsing in a book shop and saw this strange-looking book with a grid on its cover. It looked a bit like crossword with numbers and I didn’t know what it was because I didn’t speak Japanese – I still don’t. But I bought the book anyway and a few months later I sort of figured out what you were supposed to do and it was a Sudoku puzzle and wondered why the rest of the world doesn’t know about it.
