When you run out of lives...
- Do nothing. You'll automatically gain a life every 30 minutes. Granted, this means you won't be able to play Candy Crush Saga for a little while, but this is without question a cost efficient method.
- Buy more. You can purchase five lives for just $0.99.
- Ask your friends. If you login using Facebook. You can send requests for more lives. Click the heart icon on the top left corner of the screen, then press the Ask Friends button. This will launch a Facebook pop-up that allows you to select people individually.
