The event runs for a limited time but can be completed early, if the player collects the final event reward.
Coins earned from any source (completing orders, selling the items on the field, etc.) count toward the event progress. If the event is active during the Royal Challenge, crowns are counted instead of coins.
Once the progress bar is full, the player receives a reward. Further collection of the resource unlocks the reward for the next event level.
When the event ends, any unclaimed rewards will be automatically added to the player's profile.
