Are you using the app? Unfortunately, Google Play is boxing out the devs by forcing them to update to later sdks, leaving out the older devices. But, if you are able to play this using a browser, you can install the game as an app!
Using your browser, run this, and go to menu > Install/Install as App:

That should give you the option to install it as an app without using the Play Store package. It will also work offline.
