If you prefer not to receive alerts about ready barrels, automated income, or full queues, you can easily turn off game notifications through your device's operating system settings.
Step-by-Step Instructions
This method works globally for most modern smartphones and tablets (both iOS and Android):
Open your device Settings.
Navigate to Notifications (or Apps & Notifications).
Select App notifications (or Manage Notifications).
Scroll through the list to find and select Gold and Goblins.
Switch the notification toggle to Off.
Note: Because different device manufacturers use customized software interfaces, some menu names might vary slightly. If you cannot find these exact options, please refer to your device's official help manual for assistance.
