There are different types of chests you can win in the Arena and each will give you rewards. Whenever you win a battle you will have a chance of winning a wooden, silver, or gold chest. The higher quality chest contains higher quantity of rewards, but takes longer to unlock. Each chest has a timer before it unlocks and you are given the contents of it. If you do not want to wait for the timer you can always claim your rewwards immediately by using Emeralds. Star Chests are earned when you have collected 15 stars by defeating opponents in the Arena and will contain more rewards than any of the other chests.
