Customer Reviews

Hard to put down!

There's so much more learning to do...countless subjects and things I've never heard of, but yet this app keeps me hooked. What I don't care for is that a correct answer isn't given if you time out answering a question...the only way to get the correct answer is to take a wild guess, which lends a sometimes light-hearted response in the game by telling you "That was a hard one, you'll do better next time"...or something like "That was an easy one, you need to brush up". I could do without the comments myself, just to help the game move a little faster...still, I like it so far.

Good Choice

I like it. As others have written, this app is challenging and it's helpful for learning about and remembering new info on a variety of topics. I like that it's for a single player and improving one's own abilities, instead of having an opponent and trying to win.
I don't like the background music, but it's easy to go to "Options" in the menu and adjust the volume for the music,(silenced), and the sound effects, (low).
Overall, a very user-friendly app!

Fun and educational

Love this app, and I've actually learned some facts I didn't know. Comments: The rating for individual questions sometimes seems bizarre, other times right on. The "Music" category is woefully top heavy with pop and rock questions and almost NO classical music at all. If you have no idea what an answer is, guess anything; otherwise, you time out and they won't show you the correct answer to the question. Good brain activity, and it's fun!
