I really enjoy Sudoku, and this app has several more challenging versions (for example also requiring digits 1-9 diagonally) that are fun. Includes multiple levels of difficulty in each type of puzzle and multiple ways to enter digits, as well as optional hints. Definitely recommend for those who like Sudoku and to keep their minds sharp.

Love that user can turn off the highlight colors with a touch as needed so they do not distract. Love the choice to high light pencil marks or not. Love the ability to pause. This is my favorite of all the Suduko games I've tried, almost like it was created just for me. I figured out how to delete the data so no problem now. But it would be nice to have that option programmed into the app one day!

I like it. There are different types of puzzles, which make it more interesting. There are also many levels, which make it more challenging. The controls are easy to use. When you check you progress, you can see if there is a mistake or not without filling all the squares first, unlike other sudoku apps I played. A great way to pass time.
