I have managed to play this on my Wife's Samsung Galaxy phone out of box. It works, but is just slightly too large for the screen.
As others have noted, it is quite laggy. It is also a little annoying to have to actually click the "end turn" every time (I was surprised how much I missed space bar
)
I wouldn't ever want to play another PvP match on it, but for grinding PvE it was at least somewhat tolerable.
