I enjoyed the game initially so I paid for the ad free version. Suddenly most of my answers were "missing" answers, which was suspicious. Example, for "name something in a desert" the response "sand dunes" was not acceptable but "nothing" was. Or for "name a color in the rainbow" violet was missing. Oh, but you can stay in the game... if you watch a 30 second ad. These people do not know what ad free means.
