No difficulty selection! There are no ads at all though which is why I gave it two stars instead of one. Its just a board, some numbers, and a new game button! It took me a while to figure out that you had to select the box first and then click the number that goes in the box even though you can drag the numbers but can't put them into any of the boxes!!!! There are lots of other better Sudoku apps out there, and I would want anybody to waste their time or data space on this app.
