All players can have a maximum of 5 lives, and losing match-3 levels costs one of them. Once you lose all your lives, you won’t be able to play again until they recharge.
It takes 30 minutes for each life to recharge. However, there’s a number of other ways to refill them:
1. Ask your friends to send you lives. Tap the lives icon in the top left corner of the screen and then tap Ask Friends in the pop-up window.
2. Each of your friends can reply to your request and send you a life as a gift once every 24 hours. The gifts you’ve received are displayed in the Inbox window when you log into the game or tap the envelope icon in the right part of the screen.
3. You can also buy a full set of lives using diamonds.
