Sudoku

I’ve become totally, helplessly addicted to Sudoku, a Japanese logic puzzle which can be anything from ridiculously easy to fiendishly difficult. The concept is simple: take a nine-by-nine grid of squares and divide it into nine three-by-three squares using bold lines, chuck in a few numbers to start off with and off you go. Each row, each column and each three-by-three block must contain all the digits from one to nine. It sounds simple and it is, with the easy puzzles giving you plenty of information to start you off. The more challenging ones give you fewer numbers to start with and have them carefully arranged to cause maximum headaches.

I’ve been doing the Times’ daily puzzles, which start on Mondays with a nice simple problem and finish on Saturdays with a prize problem, and I’ve also been scouring the net for more in order to feed my growing habit. This thing could eat my life very quickly if I let it.

  2. Anyone out there who is a Sudoku Master? Anyone know of courses? I need a “total immersion” weekend from a Sudoku master – I would be happy to help set up such a residential course.

    I’m a qualified chef/caterer – could help in any way.
    Would just love to be able to solve the “tough” ones!

    Hope someone can help – Maureen W.
