About Classic 9×9 Sudoku

Classic 9×9 Sudoku is the original puzzle the world knows and loves. Fill the grid so every row, column, and 3×3 box contains the digits 1 through 9 exactly once. There are no extra rules, cages, or restrictions here — just clean, traditional logic. It is the perfect starting point for newcomers and a daily ritual for lifelong solvers, available at every difficulty from Easy to Expert.
