Every Sudoku puzzle is a square of 81 cells in a 9x9 grid, divided into nine 3x3 subgrids. Rules: Each empty cell must be filled using a number from 1 to 9. No horizontal row, vertical column or subgrid can contain two of the same number. Each puzzle starts with a set of numbers placed on the grid, that you cannot change. No mathematical operations are required. The game requires only logical skill and patience.
