Sudoku—What’s all the fuss with this game

I’ve noticed a lot of talk lately about the game Sudoku. It seems like this is becoming very popular in Europe and is gaining steam in the United States. Wikipedia states that Suduko is:

Sudoku ,, also known as Number Place, is a logic-based placement puzzle. The aim of the puzzle is to enter a numerical digit from 1 through 9 in each cell of a 9×9 grid made up of 3×3 subgrids (called "regions"), starting with various digits 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 logical ability. Although the puzzle was first published in a U.S. puzzle magazine in 1979, it initially caught on in Japan in 1986 and attained international popularity in 2005.

To tell you the truth, I don’t really understand the game Sudoku, but I see now Microsoft is even getting into the game with a digital version for Mobile PC. Perhaps we will be seeing more of this game around as time goes along. To find out about the MS version see
