Not sure how to force close an app on your device?
You may need to have a look in your task manager to clear any processes which aren't necessary while you are playing the game.
Double tap your home button to enter multitasking mode, then swipe upwards on each app's screen preview (not the icon) to close it.
Apps such as Facebook & Messenger may continue using memory even after they have been closed in the multitasking menu.
To check for this, go to the Background App Refresh section of your device settings, then toggle OFF apps such as these to prevent them from using additional memory while you play. You will also need to restart your device to make sure that the memory has been cleared.
iOS 6 and previous
Clear your multitasking tray by double tapping the home button to bring up the tray, then tap and hold on one of the icons until they start to shake. Tap all of the little red icons to close all of the apps in the multitasking tray.
- Tap on “Menu” from the home screen of your Kindle Fire HD.

- Select the app you want closed
- Tap on “Force Stop.” That particular application will now be closed.
Windows Phone 8
You can now quit applications by holding ← (back) and then clicking the Ⓧ (circled X) that appears in the top right corner of the application.
Since 8.1, users can also swipe down on an application in this view for the same effect.
Close the game completely when you're not playing
A common issue for players can be loss of progress the next time that you open your game. *Disappearing save data or progress can also be a sign that your device is experiencing performance or memory issues, by force closing your game while it's running in the background without saving when you are using other apps. When you're done playing for the time being, you should always try to ensure that the game is closed completely before you go about doing other tasks on your device.
