I suck at this game. I think they could show a pic of the US and it would still take me 5 guesses to get it.
I actually like this game a lot. I've always been pretty good at geography. But they have a game called "Statele" that is exactly what you're talking about. They show a silhouette of the state. I crush that game. But after you've done all 50, the game is over for you at that point.
I also like the ones called "wheretaken". It shows a pic of somewhere in the U.S. or the world (they have two versions) and you have to try and guess where the pic was taken.
