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!

A brainpower building app that doesn't (DOES NOT) force you to watch an ad after every puzzle completion. The developer provides a setting>advertisements option to choose an ad banner at the bottom of the screen instead of the "traditional" irritating full size advertisements. Good job, developer. There is the traditional puzzle and several other layouts with an easy-to-change degree of difficulty. This dev has a newer Sudoku app out that lets you import printed puzzles. The UI / UX is great.

Hi there. Puzzle "very easy #2" is unable to be completed. When entering the number 4, in the middle section of boxes, the numbers are hard coded incorrectly.You cannot put number 4, in the only space it can go, because then it says it's a duplicate. Please fix! Otherwise it's a good game.
