http://addictinggames.com/50states.html I don't know if it has been posted here or not already, but I enjoy playing it. My best so far is 4 miles error. A lot depends on the luck of the draw as to the order the states are presented. If you get some of the rectangle states or the Midwest first it's easy to miss by a bit. There is also a state capital game on the same sight where you try to place the state capitals on a map.
