If you are addicted to Candy Crush Saga and hate having to wait for lives, there is a semi-quick solution. When you are playing through Facebook and run out of lives you will see a pop up screen asking you to help rescue pets in Pet Rescue Saga. If you complete 8 levels you will be rewarded with a set of lives for Candy Crush and five Lollipop Hammers.
If you agree to help you will have to allow the app to access your basic information and the app will show up on your list. Beating the levels needed to get the free lives and hammers are not tough but it seems a little counterproductive. Play one game, get hooked on it then be told there's another game that can help you earn things for the first one. How long before they make this a triple tier and add another game?
