just noticed that each time you open the link to the site it rerolls the order you place them on the map in. some rolls are harder than others, my second try was only 80% cause of all the states that I had to place without any bordering things to go off of. If I don't have to guess where in the middle of empty space a state is I do pretty good.

I only missed Arkansas because it was out in the middle of nowhere with no frame of reference. And I was still pretty close!
