THE RULES...

The Daily Sudoku is played over 9x9 grid, in each row there are 9 slots, some of them are empty and need to be filled

Each row, column and area(3*3) should contain the numbers 1 to 9 however:

Number can appear only once on each row

Number can appear only once on each column

Number can appear only once on each area (3*3 slots)

The bottom line : the number should appear only once on row, column or area.

However; above all the ultimate challenge behind it is doing it fast!
