Every player starts with 5 lives. Failing to finish a level with at least one star will cost the player a life. This life is already discounted when a level starts and you get it back after a victory. Regaining that life will take 15 minutes including the time you needed to lose the level. Otherwise it will cost Gold Bars or in-game friends need to be asked. Excess lives that are sent to you will be converted into 100 Magic Beans. This is a major source of income in this game.
Lives sent to you can be stored in your mailbox, just like in Candy Crush Saga.
