Chests

Summary

 * Earn chests to unlock rewards, collect powerful new cards, and upgrade existing cards.
 * Chests range in rarity from Silver to Golden to Magical (i.e. it is more likely that you find a Silver at your Arena Level than a Magical or Golden).
 * Destroy opponent’s towers and win Crowns to earn Crown chests.
 * You get a free chest every four hours which contains gold, gems, and cards. You can hold up to 2 free chests at once.

Free Chest

 * Uncollected chests will stack (maximum 2) for unlock the next time you are online.

Trivia

 * The Silver, Golden, and Magical Chests cannot contain gems, however the Free and Crown Chests can.
 * The Silver, Golden, and Magical Chests will always contain some amount of gold.
 * The cost to purchase a chest increases based on the arena you have unlocked. The higher the arena level, the higher the cost.
 * Since you can hold up to 2 free chests, you can log in once every 8 hours to collect without losing any possible "free chest time". This also means you can get up to a maximum of 6 free chests per day.
