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.
In this latest collection from Wayne Gould, you confront the ultimate mental workout with 150 all new Fiendish Su Doku puzzles. 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 Su Doku puzzle for what it is—a thing of beauty!'
