This classic sudoku is taken from my new book WORLD OF SUDOKU : VOL # 4. The book contains 120 handcrafted classic sudokus ranging from moderate to tough. This sudoku was also featured on the YouTube channel Cracking The Cryptic today.
RULES :Place a digit from 1 to 9 in each empty cell so that each digit appears exactly once in each row, column and 3x3 box.
