About Sudoku Games
Sudoku is a number puzzle that does not need any math. Fill a 9×9 grid so that each row, column and 3×3 box contains the digits 1 to 9 exactly once. Every proper puzzle has one solution you can reach through logic alone.
Start with the rows, columns and boxes that are nearly full. When you get stuck, use pencil marks to note which numbers are still possible in each cell. Enjoy puzzles that use your head? Try word games next.
