Now comes Google Gadgets

Now I have just found them, I am looking forward to find out how I am going to make the best use of the three: Google Spreadsheets, Google Gadgets and Excel, all combined on a single web page like this or each separetely like juggling, but with an option to link one to another.

"Sudoku, the number puzzle that gripped England from the fall of 2004 has now taken hold over 70 countries. Some 260 newspapers in the U.K. carry the maddeningly habit-forming, logical-testing grids and sudoku is looming large in the U.S., Spain and Israel as well.

Yet, in Japan, where the name and current version of the puzzle originated, sudoku is still relatively unknown. Nikoli, the Tokyo company that originally published sudoku, and Maki Kaji, the man who gave it its name, are far from household words."

Nikoli, whose online agent Puzzle Japan has just been closed down, now announces its own worldwide website Nikoli.com Coming Soon!!

It was just a couple of weeks ago that I heard of a friend of my wive's who lives in Paris, and whose husband, a Japanese, works with Toyota there. She is a housewife, seemingly having some free time with both of her children grown up to be artists, one as a pianist and the other as a dancer. She had just said to my wife on her recent home trip to Tokyo that she is crazy about sudoku, somewhat now addicted and devotes most of her time, when she is not with her family at home, to sudoku.
My wife, not a kind of woman interested in anything that holds number, got curious and then searched Google for sudoku.

As soon as I heard this, an idea coming to my mind was "why not use Excel to do sudoku".
After spending some hours in designing Excel sheets as I tried a couple of puzzles on it during last weekend, I have made my first spreadsheet for sudoku.
