It seems you are trying to make a per-programmed robot to put a jig saw puzzle together before you have dumped the pieces on the table. Maybe try just taking the pieces as they come. You’re only putting the edge pieces together now. Go ahead and turn all the colored-side up as you find them.

I think it would be way too hard to grab a random piece and start on a hunt to find where it exactly fits. You only take the parts with one straight edge and start slow. You’ll know when you find a corner piece with two straight edges. After you’ve worked your way around with all the straight pieces, you’ll know the size of the frame.

Your puzzle came in a plain brown wrapper. Don’t decide what the picture is yet.
