This is addicting. I did the 25 United States Cities 100% correct and a score of 46.8 seconds. However, you can identify states, and other countries and in the world. I did okay on the South America, not so well on Europe (I know, I know), even worse on Asia....and...unfortunately ABSOLUETLY HORRIBLE Africa. I haven't even been able to bring myself to attempt Australia. Anyway, if you want to give it a whirl...go for it. I would be interested to see your score!
