How to "force close" the game?

Unknown

In order to switch facebook accounts that are linked to the game I was given instructions that started with "force close the game."

How do you do this?

I just want to make absolutely sure that I don't mess up and lose all my characters!

Thanks!

On iOS you double click the home button and up-swipe MPQ to force close. On android I think just swiping it away when you bring up recent programs is enough to force close it.
