3 stars: Some possible mistakes ...? Reading fathoms is not restricted only to ocean measurements (i.e. Mark Twain on the Mississippi River). Also, the question of the number of Russian Olympic medal winners is badly worded. Apparently, the question refers only to total wins from the beginning of their participation
4 stars: I love this game. It's challenging & fun. Although I don't mind the pop-up ads at all, I HATE the flashing ads at the bottom of the screen. They give me a horrible headache and are very, very distracting.
3 stars: This is a pretty good app, not too many ads and easy to dispose of. But. It is too American. Very few people outside of the USA could care less about baseball and nfl. Just sayin'.....
5 stars: Very informing. I don't mind the ads because I don't really notice them since I'm so engrossed in the game. Having fun while learning a thing or two!
3 stars: Should have some easy questions mixed in with current questions. Been out of school too long. Would like to have categories to choose from. At 65 I'm still learning. Thanks
5 stars: Easy to use, clear questions on a large variety of subjects. I haven't tried multi-player yet nut I can't see that as a problem.
4 stars: I think it is absolutely great. I did find one wrong answer and that is it. I would like to see a few multiple choice questions. Perhaps just one or two of the challenges.
5 stars: I hate the fact that I am told all are wrong! Otherwise, good fun...
