Aidan,
I downloaded the Cribbage game (again) from the Google Play store and when I try to subscribe for a year with the a Google account balance, I get a transaction failed error. Are you still supporting your Cribbage game for Android users? I noticed that there are no other GrassGames in the Google play store so I was not able to find/download the non-free version of Solitaire 3D. I get the impression that you may be "retiring" or downsizing things? Maybe the costs of keeping a game in Google Pay are not worth it?
Thanks, Bill
