Reassemble the puzzle to a square and then solve it with the usual Slitherlink rules. You are only allowed to rotate the pieces, but not reflect them.
Example:
The puzzle is available online at Penpa. Use for example the "Edge"-Tool to draw lines or mark them as missing. I left some space around the borders to allow you to mark which borders are adjacent.
Have fun!
Solution code: The sizes of all regions outside of the slitherlink in the assembled state, sorted in ascending order. In the case of more-digit numbers please include all digits. In the example the solution code would be 1 10.

Super Rätsel! …und auch ganz schön schwer, wenn man es nicht auseinander schneidet. Dann verknotet es einem schon ganz gut das Gehirn. Tolle Idee - vielen Dank!
