Using a Samsung Galaxy Tab with Android 4.4.2. The game downloads, goes through the installation process, gets to the end then just says, "App not installed" no error message, no explanation, just "app not installed" - done.
Loved the first two games, this was an insta-buy when I saw it. Maybe they'll patch it so it works, or maybe they'll flag it as not working with this device. I suggest you hold on to your pennies for the moment, wait for a patch
