Those of you who enjoyed Judge Aldisert's logic puzzle (puzzle here; solution here) would probably enjoy Sudoku. For those of you who are already Sudoku addicts, I offer my Sudoku worksheet. I suggest copying the numbers from the puzzle onto the worksheet by pen, then solving the puzzle by pencil. If you're already addicted to this little game, then you already know why the worksheet has the little numbers pre-printed inside each box. Enjoy.
