If Google Play prompts you to load a different game, it means your device has been connected to another Google Play account. 

To stop these prompts, either:

• Sign into the correct Google Play account connected with your original game, or
  
• If you still have not connected your game to Google Play, you need to add a new GP account to your device by entering your device's Settings > Accounts > Add account (please restart your device after adding a new account)
  

Remember to connect your base to Google Play with the Google Play Sign-In button.
