We rely on Google Play to efficiently administer compatibility so that we don't have to directly keep track of which device/OS combinations are/aren't compatible with the game. In a web browser, please go to this website:
and log in with the same Google account that you use on your device. It should give you a message to the effect of "This app is compatible/incompatible with your DEVICE_NAME."
One exception to this is that Google Play incorrectly thinks that the app needs GPS to function properly. If Google Play won't allow you to find/download the game AND if you have a device that doesn't have GPS (some tablets), then please email firstname.lastname@example.org. We can give you a link to try downloading the game directly from us.
