This being the Lite version, there are just the same 20 questions (in a different order each time), which are challenging, & designed to entice you to want the full version at $1.99. There is also a gallery of photos, but no captions to tell you who, what you're looking at, and a Recommended Reading List. If you know your Hitler's Germany, this will be a breeze; if you remember some, it will be anywhere from medium to hard; if you don't know, or remember anything, you will learn a few things! I hit right between the first & second, and thought this app (and the others like it) fun and good memory boosters! As I can afford them, I will try the full versions of some. Enjoy a fun, free brain challenge!
