21 Sudoku

Sudoku is a puzzle game designed for a single player, much like a

crossword puzzle. The game involves a square grid with 9 columns and 9
rows. There are also 9 smaller subgrids of 3 × 3 squares.

Fill in the grid with digits in such a manner that every row, every column

and every 3 × 3 box accommodates the digits 1–9 without repetition.
