To unlock the Crown chest, you need to get 10 crowns within a day. For each day I have played so far, I managed to get this (most of the time easily). However, today is the first day I will not manage to reach this limit. I am at 8 (of 10) right now, and I do not have the time to play a game (yes, I do have the time to post this question).
I don't mind that I cannot open the crown chest for today, but I am probably busy tomorrow as well. Do I have to start from scratch, or can I continue with 8 chests, and skip a day?
