A message popped up "What do I think about Klondike?" Then multiple choice options to answer. What is Klondike please? What does it have to do with Candy Crush? Lol
Depending on where you live in the world Klondike is the name of the card game solitaire, or patience. As far as I know it has nothing to do with King, or Candy Crush. It is more than likely a survey from Microsoft, as solitaire is one of the games you get on a PC.
