Finally a simple basic sudoku app. Downloaded and deleted 4 others before this one. Ads are very minimal too. Good job!

Layout is great. But gameplay is glitchy. You have to select the number several times in order for the program to register and even then, the number selected is not always the number that is entered in the box. Developer needs to address this.

Adjustable hints

As player increases skill level player can adjust error allowances. Very good for any level skill!
