Every character I want to guess is "rare". And after watching an ad for every character it might not even be the right one, if it's wrong then it's literally faster to restart the app than start a new one through the app and watch another ad. To get the so called awards you have to make him guess first try, and that might literally be impossible for some characters, because he won't ask the right questions and jumps to a guess after asking something completely irrelevant.
