Sudoku Puzzles, previously known as ‘Number Place’ is a logic based numbers puzzle, where the player should enter a number from 1 through 9 in the empty cells of a 9 X 9 grid. The 9 X 9 grid is subdivided in to 3 x 3 sub grids. Every completed puzzle will be a Latin Square and every sub grid will also be a Latin square. Latin square is a square grid where the same integer will not appear twice in the grid’s row or column. In case of sudoku the same integer should not appear twice in the same row or column in any of the 3×3 sub grids or the 9×9 entire grid.
