Italians got crazy about a new game called Sudoku. The Italian press is full of Sudoku puzzles and there are even some forums. Here is one of them: Corriere.it/Sudoku forum

I also observed the phenomenon in the british press too. For example The Guradian has a book with Sudoku puzzles that you can find just “in a good bookshop”.

Here are some web sites where you can play this game on line:

Sudoku, sometimes spelled Su Doku, is a placement puzzle, also known as Number Place in the United States. The aim of the puzzle is to enter a numeral from 1 through 9 in each cell of a grid, most frequently a 9×9 grid made up of 3×3 subgrids (called “regions”), starting with various numerals given in some cells (the “givens”). Each row, column and region must contain only one instance of each numeral. Completing the puzzle requires patience and modest logical ability (although some puzzles can be very difficult). Its classic grid layout is reminiscent of other newspaper puzzles like crosswords and chess problems. First published in the United States, Sudoku initially became popular in Japan in 1986 and attained international popularity in 2005.

The word Sudoku means “single number” in Japanese.
