Ultimate Sudoku game
Welcome to Ultimate Sudoku, a fun number game where you fill a grid with the numbers 1 through 9. Each number can only appear once in each row, column, and box, and you can pick from three difficulty levels: easy, normal, or hard. Start with the rows where you have the most numbers to make it easier. And if things get too tough, turn on the notes. But be careful, it will cost you half the points.
