If the notifications for any application on your Android device are becoming intrusive, there are a number of ways you can turn them off.
The steps can often vary on different Android devices, depending on the device and the version of the operating system you have installed.
However, one quick way to access the switch for notifications on any device is to tap and hold any notification you receive. This will bring up the notification settings for the game or application.
You can adjust the settings in the menu, to pick and choose which apps you receive them for.
Your own device's documentation and support pages will give additional guidance specific to your device.
