Crowns

Crowns are a way for a Player to:
 * Instantly finish / purchase extra Resources or Workshops.
 * Instantly finish exploration at Places of Legend.
 * Purchase certain Decorations, Special Heroes, or materials you do not have.

These can be obtained through various manners, such as: Chests, In-app Purchase, Quests, and spinning the Wheel of Wishes. There are times where Zynga might have made an error or had an issue and will give Players Crowns for these instances.
