Do you play Sudoku?

Sudoku is a combinatorial number puzzle. You have to fill in a 9x9 grid with numbers 1-9 in each line and in nine 3x3 squares. I started doing it back in 2005 when they started it in Indian newspapers!! I still do it in the newspapers and sometime on this website: Link

Today while searching for computer accessories, I found this product on deal:

The description of the product says "We all know that having a sit down can be a time consuming and boring process. Some people read, others sing. Why not play Sudoku with your loo paper?
The perfect gift for the person who has everything!"

As they say, if you are addicted to it, you would find time and place for it.\
