United States

IconPolyStudio, 132 pieces. Acrylic puzzle with no indication on the pieces which side is up (it didn't even say it was a picture of the US, but I figured it out when I saw Maine). Very difficult, not least because a couple of connectors fit in more than one place, like a Stave Trick though I think less intentionally. Despite a basic strip cut, it took me hours! 3/5
