Puzzle No. 2: Harder

What is Sudoku?

Like Tallulah Bankhead, I wanted to say `there's less to this than meets the eye.' But it's just not true! Despite being deceptively simple in terms of the rules there IS rather a lot to Sudoku.

Sudoku (meaning `numbers singly' in Japanese apparently) can really get you hooked! While waiting at any airport these days you will probably notice several people doing the little puzzles, sometimes working together.

Millions of people worldwide are `addicted', with the top ten books in the non-fiction best seller lists dominated by Sudoku, or Su Doku as it is also known.

The solution to the easy puzzle on the right can be found here.

Several daily newspapers carry the puzzles, with the Times leading the way initially in the UK. There's even been a live TV programme on Sudoku hosted by Carol Vorderman.

What do you do?

The aim is to fill in the grid so that each row, each column and each 3x3 box contain the numbers 1,2,...,9. Simple as that! However, it's not always easy of course, and sometimes fiendishly difficult. But it's fun to learn strategies for yourself by just having a go!

Unlike crosswords Sudoku grids can be automatically compiled by a computer. However, one must be careful to check that there is only one solution, and hand crafted puzzles by experts have been claimed by some (e.g. the Guardian) to be superior.

Sudoku originated in the 1970s from the USA (where it was called `Number Place') and really caught on like wildfire in Japan in the 1980s and in the UK since late 2004. It is now quickly spreading worldwide.
