On the upper left corner of your screen, you will see a counter that will show the number of lives you have left. As you use your lives, they will be refilled one at a time every 60 minutes, until they reach a maximum of three unities. At this point, the counter will no longer be refilled.
However, you will have other ways of getting more lives:
- Spinning the Prize Wheel.
- Buying them in the game's Shop.
We invite you to visit the article: What are lives for?, so you can learn about how these items work.
