It's a cool concept, but 99% of the time you're staring at an ad. Everything has to do with ads. Hardly any breaks from them unless of course you pay to have them removed. There are several correct answers that I've gotten marked wrong. It's super simple to cheat on this game too, so if you don't know an answer, you can actually click out. I think it'd be cool if the response was timed or if you exit the app, you forfeit the game. I loved playing it. I just couldn't stand the hundreds of ads.
