Sudoku

I bought this little Sudoku booklet from a friend a while back (it was for a charity fund-raising thing). I tried the first puzzle, didn't get it right, and decided sudoku wasn't my thing. Until now. I was determined to get the second puzzle right. And I did! I think I got the hang of it now and I've gone through about half the booklet already. Good pastime to have. Helps keep my mind sharp. I think. :)
