Overall a very great app. Sometimes a little tiny for my eyes (thats what reading glasses are for) but I cant say enough about the great interface. Having the numbers in keypad format surrounded by the options is a very nice layout. Im not a good Sudoku player so the "easy" might be a bit simpler to help beginners. Im sure the other levels are great. Has some nice assist features (highlight shows all the places a particular number can still be played; auto shows only the numbers than can still be placed in a cell) - excellent app. Thanks!
