New York Post Difficult Sudoku

HarperCollins Publishers, Inc.

Since its launch in The Times in November 2004, Su Doku has become one of the most popular features of the paper and an international phenomenon. In a world where time is apparently a precious commodity, it is a testament to the addictive power of the puzzle that so many people can't wait to tackle it on a daily basis and with such intense concentration. The Times books, once they appeared in the bestseller lists, haven't budged since, showing their huge popularity with the book-buying public.

Here is a collection of 200 previously unpublished Difficult Su Doku puzzles from Wayne Gould, the man who started it all. This level is ideal for Su Doku solvers who enjoy the more challenging puzzles. Once mastered, why not give Fiendish a go?

Remember, these puzzles require no guesswork: logic will lead you to a single solution. A valuable tip from Wayne Gould: 'If you are writing too many pencil marks, it means you are not understanding how the puzzle works. You may be relying too much on mechanical procedures, without appreciating the underlying logic. If, in time, you can shake yourself free of written pencil marks, you will see the SuDoku puzzle for what it is -- a thing of beauty!'
