Welcome to the Candy Crush Saga Community
Do you have a question or need help with your game? Ask the Community.
Are you IOS 7 or IOS 8?
Force close all your running apps, double tap the home button, then if you're ios 8 swipe everything upwards and they close. If you're ios 7 touch the red x and it closes that app.
If you continue to have problems, you may need to check your iPad space and make sure you have some room, if not, delete the CCS app and re-install it.
Also, Puffin browser is an awesome app that lets you play Candy Crush (Many other games) on Facebook, just as you would on a computer.
