                 The goal of Sudoku puzzle is to fill a grid with numbers so that each row and
                 each  column contain all of the digits.



                           Basic tips to solve a Sudoku:

                           •    Only use each number once : Do not repeat any number.

                           •    Scan in one direction first.


                           •    Look for the most filled row or column.

                           •      Keep looking and spotting opportunities to place numbers
                                where they haven’t already been placed.

                           •    Use the process of elimination.
