This game has a step-up ad watching reward strategy. It's a good strategy! Problem is you'll watch an ad and a glitch will leave you at the same step, not advancing you to the next step OR reward you gold for watching the ad all over again at that step. A glitch I'm sure they are aware of and do nothing about. A glitch that's been there since I started playing. A glitch I'm sure costs them atleast half a star in their rating but hey, Getting people to watch 8 ads a day is more $$$ than 5!
