As far as solitare goes, this app can deliver. I haven't had any issues with the gameplay so far. But the customization absolutely sucks. Which is why I'm giving four stars. When making a custom back for cards, there is an annoying white border that is impossible to get rid of that ruins almost every image I try to use. And with the "Add Images to Cards" function it only lets you place the image on one spot on the card. This customizable system used to be good, but has since been ruined.
