Sudoku is an old puzzle, like many folk games, now we hardly know who discovered it. As the name Su doku (数独) reveals, it was valued in Japan. This puzzle is introduced to Britain recently and widely spreads. Thanks to a retired judge from Hong Kong, Wayne Gould (高樂德), he learned and popularised it from Nippon (also with his self-produced software). A number of British newspapers like the Times, the Daily Mail and the Independent have started to print with a section of Sudoku. It is a game of simple rule (just fill in 1-9 in columns, rows and grids), but difficult one (you could try the advanced level). Would it replace the crossword section some day? Interested could have a look in the Times.
