I made a tablet version of classic.
It can be accessed from home page, tablet menu item and you can play the daily grids.
So it should be opened by any operating system.
I'm not sure of graphical output, it works on my sansumg s3 and on my son's Ipad.
for smart phone perhaps it's better http://www.argio-logic.net/sudokusmart.html but it's not, for now, designed for daily grids.
I'll be gratefull if you can send me a screen capture from your device if anything goes wrong, especially for pencil marks position, specifying your system properties.
