Game was pre-installed on the surface duo and I have an Xbox/MS acc so free achievements for me. Overall this app has everything solitaire has to offer and more. I can't complain since I don't see ads but anyone can get free premium if they know how to obtain it by spending points on either GPU & Gold Live or by spending it points on MSSC 1 month premium. You really don't need to spend a dime on this app (I know 2 ppl who haven't known this until I've told them about it).
