The amount of ads were INSANE. I paid for the ad-free version because I liked the concept. There are so many missing answers and inconsistencies on what types or answers are accepted (plural or not is one of many examples). Incredibly frustrating. Also it creates the illusion you are playing against random opponents but you are clearly not, you are only playing computer opponents. I love the concept but hate the execution. Deleting even though I bought it a few days ago.
