Entertaining and challenging

An enjoyable way to improve your knowledge base, and deductive reasoning skills. The questions are multiple choice and cover technology, the sciences, literature, history, the arts, sports, popular culture, etc. Even if you don't know the answer, you can sometimes figure it out from the context of the question. With 10 questions per game, it's easy to track your progress. Encouraging comments after each question provide positive reinforcement and make learning fun!


This game has the most random questions like "what movie did Tom Hanks win an award for?" It is not actually a game for "smart" people, it's just a game. If you're hoping to learn from this, then be prepare to gain a lot of useless knowledge along with the few history and geography questions it has. You can't even choose the category to play trivia (at least not in the free version, and who is actually going to spend money for an app)? And when you can choose the category, it repeats the same questions that you missed and that's all you can do in said category.


Too many movie, literature and obscure sports questions that only the diehards in those categories would know. Which is probably what someone else is thinking about my categories.
Other than that, it is thoroughly enjoyable. Very hard to put down at times.
