How to Play
Sudoku is a logic-based number placement puzzle. The objective is to fill a 9×9 grid with digits so that each column, each row, and each of the nine 3×3 subgrids contains all of the digits from 1 to 9.
The puzzle starts with a partially completed grid. Your job is to fill in the remaining cells. The more difficult the level, the fewer cells are revealed at the start.
Be careful! You can only make 3 mistakes before losing the game. You can still continue playing after losing, but your score will be reduced.
