This thread has turned into irrelevant information from OPs POV.
You absolutely can get Google Play on your Kindle, xda forum guys have been doing it for a while. However, you can sideload the CoC apk onto Kindle's FireOS, heck you could sideload it into the new Blackberrys BB10 OS which also run Android apks.
This does not, however, obviate the fact that you can't attach whatever base you have on your Kindle to Google+ or GC; so at that point, you have to be very careful about keeping your device, and you'll never be able to link it to Google+ or GC in the future (SC has the same probability of supporting FireOS and Amazon User accounts as they do of supporting Windows 8 phones and XBOX Live Accounts - i.e. basically zero).
In short OP, go for an el cheapo Android KitKat or Lollipop tablet and call it a day - or resign yourself to not being able to attach to GC or G+.
