Lives are how many attempts you have available to play levels. You can have a total of five, and you lose one every time you fail in a level. It takes 30 minutes to refill one life.

You can see how many lives you have and how much time you have left until one is refilled in the top left corner of the map screen. You can also purchase life refills or ask your friends for them!

IMPORTANT NOTE: If your friend sends you an extra life when you are already full, you won't be able to use it. But don't worry! That life will still be available once you lose one of your lives.
