I'm guessing 6, maybe 5S, but more 6 for screen size. Unfortunately I have a 5C so it'd suck if that's true.
My best bet (considering the iPad requirements) is that it will work from iPhone 4s and up, that's just me wondering
Yess, but if 2K made possible XCOM to run on that screen, I bet that Heartstone, as small as it would look, could work.
Jb'd and got it going on my 6+. It's playable there. Things like deck editor though with those card placeholders over on the right are tiny even on the 6+. So anything smaller will require a re-jig. Personally I think the UI for that deck builder is no good, even on iPad. Will be interesting to see how much they end up re-jigging the iPhone version.
