About Sudoku 9x9
Sudoku 9x9 is a number puzzle played on a large grid divided into rows, columns, and smaller squares. Your task is to place digits from 1 to 9 so that each of those areas contains the full set without repeats. The challenge comes from using existing numbers to work out which entries can fit.
Three difficulty choices let you select an easier, medium, or harder starting arrangement. Easier games begin with more numbers already filled, while harder ones provide fewer clues. Hints are also available when you need help resolving the grid.
