Lives

Lives is the fundamental element (and sometimes can be the most hated element) in Korean version of Angry Birds, Angry Birds POP!, Angry Birds 2, and Angry Birds Blast! They appear in the top left side of any game. The maximum possible lives without having infinite moves is 5. You can earn unlimited moves for two hours by getting special offer after making an in-app purchase.

If you have one or more lives, you can play the level. If you fail the level or press the quit button (doesn't happen on Angry Birds 2 and Angry Birds POP! before shooting the first bird/bubble), a life is lost. When you run out of lives, you are not able to play any level.

Running out of lives
There are some ways to get more lives. However, the players don't want to wait, so there is another way to get lives.
 * Waiting. The basic way to get more lives. Each game you have to wait for 30 minutes to recharge each live. You can get the full set of lives after 2 hours and 30 minutes. In the web version of Angry Birds POP!, the lives are synchonized with the mobile version, so if you have no lives left on mobile version, there are also none of them on the web.
 * Ask friends. You can ask your friends for more lives.
 * Watch Video. Some games you can claim the offer by watching a short video for one additional live.
 * Move the device clock forward. You can set your device clock forward to get instant set of lives.

Buying Lives
No matter how many lives you have, you have to spend the same amount of coins/gems/ or golds to refill lives.

Other Appearances
In the Angry Birds Star Wars Weekly Tournament on Facebook the player has five heart-shaped crystals to play tournament levels. In the December 15, 2012 update, you have five crystals, which has the same method as ones in Candy Crush Saga. However, each crystal requires 12 minutes to recharge. The player can spend credits to buy more of them. Note: You can store more than five crystals at a time. You can spend  100 for  10, and  400 for  50, or ask friend for one crystal for 24 hours each friend.

However, on April 2, 2013, the crystals are adjusted. Now you have 15 of them instead of 5 and each refills every six minutes, but every game costs one. The player can also send one crystal to the same friend every hour instead of 24 hours. In the shop, you can get double amount of crystals each purchase.
