4 stars: I like this game, covers a variety of topics. My criticisms are: 1. I don't understand some of the answers to the arithmetic questions. I would like an explanation. 2. When I close the app and then go back in later it will give me many of the same questions.
5 stars: the questions posed are very good and make you think about things that you have not encountered since high school. it is a fun game to play, it has many ads but they are easy to get rid of on a one-by-one basis.
5 stars: the primary colors answer is wrong. other than that the game is fun and the questions are random, hence the 5 stars.
3 stars: Fun game, but the questions are obviously translated because they are frequently worded strangely and/or grammatically incorrect. Additionally, about 5% of the answers supplied are wrong.
5 stars: Fun! Very little ads,and you learn!
4 stars: Love this game! One thing I wish it had was the explanation of the correct answer.
4 stars: Nice App though there's a mispelled words that have to fix.
4 stars: fun easy game just wish there was just a little bit more time to think about my answer
5 stars: It's a great app, it's perfect for me. It really helps me a lot
4 stars: Some of these are tough. But I really like the game. It makes me think.
