Sudoku

I just got back from London the other day, and while I was there I noticed bunches of people on the tubes playing a game called Sudoku. Melanie had seen it somewhere before, so she filled me in. The game board looks like this:


















The object of the game, according to sudoku.com is;
"Fill in the grid so that every row, every column, and every 3 x 3 box contains the digits 1 through 9.


















You can download a desktop version for a 28-day trial or purchase it for $14.95, but I bought a Sudoku book in Iceland, and kinda enjoy using the old pencil (with eraser) method.

Be prepared to be caught-up, because its highly addictive.
