On the upper right corner of your screen, you will find a counter displaying the number of lives you have. As you use them, your lives will be refilled one at a time every 30 minutes, until they reach a maximum of 10 units. At this point, the counter will no longer be refilled.
However, you will be able to get them through other means and increase the number of lives you have. Such means are:
- Buying special packs in the game's Shop.
- Buying daily offers.
- Spinning the Lucky Spin.
- Requesting them to your teammates. Bear in mind that if you're part of a team you'll be able to request lives to your teammates. You'll receive a life for every teammate that helps you until you reach a maximum of 5 lives per request.
