Stack the Countries

I downloaded Stack the Countries and our family has had a blast playing it. When you answer a geography question, you get the opportunity to drop the shape of a country on a platform. The object of the game is to answer questions so you can stack countries high enough to cross a checkered line. There's a little bit of geometry involved as you have think about how you stack the countries. If you stack poorly, your countries will roll off the platform. I know this from experience. Once you have stacked enough countries to cross the line, you will earn a country. Earn enough countries and you will unlock two more games (Map It! and Pile Up!) to play. This app is a lively way to improve your geographic knowledge.
