I really wanted to love this game. It's turning out to be a love-hate relationship. Not even because of the ads. People seem to forget apps cost money if they don't have ads. I'm disappointed with the inconsistant vocabulary of the actual game. Ex. "Name a type of metal" I said alkaline earth : rejected "Name a sports team" I said Blackhawks: rejected but "name an NHL team" Blackhawks again : accepted. I would suggest a wider, consistent vocabulary, skill-level matching, & more questions.
