The levels are definitely rigged so that you end up 1 to 2 steps short of finishing, so you have to watch an ad to proceed (this happens all the time with almost every level so it can't be accidental). Then there are the jelly Queen levels that suddenly spawn massive combos for the green jelly just as you're about to win. It used to be a relaxing game, now it's just infuriating. I'm basically hate-playing at this point. Time to delete, just as with Facebook.
