The goal of Sudoku is to fill a grid of 9 x 9 cells. Each cell is also divided in 3 x 3 grids (also called 'boxes' or 'regions') with numbers going from 1 to 9. Some numbers are already placed in the cells. No number should be repeated in the same line, column or grid. A Sudoku is well posed if the solution is unique.Summarizing, the grid should be filled with numbers in such a way that each line, column and box of 3 x 3 must contain the numbers from 1 to 9.
