Sudoku

Yes, I have to admit it I'm a Sudoko addict. I like to do one puzzle per day and this was very much helped by my son giving me The Times calendar and Sudoku puzzle kit for Christmas. Some of these can be quite or even super-fiendish. There are occasions when I wonder why I'm doing it but on the whole I enjoy the mental stimulation that the game brings. Much better than crossword puzzles in my opinion.
