I got out...yippee..and now am in Peru which is even worse. anyway, I got out by concentrating on the cebter section and parking only one or 2 tiles on the top at a time BUT the tiles I put there were ones that I could have gotten off by using the side panels. So I really just let them sit out of the way until I could match them in the center. Then if I had no choice, i would match them and get rid of them but then would sit only 1 or 2 up there again.
I don't know if that makes sense but I did it very cosciously and was out in a couple of hours.
This was different than just concentrating on the middle.
Now, can anyone help me with Peru????
