5 stars: I love this app!! It is very fun to play. so many good questions. I like the categories to choose from and the fact the questions get harder to answer. Very leisured pace. Thanks a bunch developers for one of my staple games I will keep and enjoy for quite a long time.

5 stars: Very addictive. You can set your own pace. Great way to pass the time while waiting for a plane or standing in line. Needs more questions -- I kept getting questions i'd already answered.
5 stars: I like the fact it's free. Other games say their free but then you have to buy stuff to play...
