The layout of the ads is designed to push you to buy premium. That would be fine if the free app didn't already include a lot of in-app purchase options. Can't even report questions that aren't on the Classic Game mode. And there are a lot of reportable questions outside Classic mode. From incorrect multiple choice options to wildly bad spelling. I'm all for user created questions as long as you can make suggestions for improvements in every game mode, especially if you are paying for lives.
