The whole diagram has to be divided into rectangles of two orthogonally adjacent cells respectively. In each rectangle the content of the cells is swapped and then an Oc2podspath has to be drawn through the diagram:
Draw a continuous tour by connecting each cell with two neighbouring (orthogonally or diagonally) cells. The path moves horizontally, vertically or diagonally from cell to cell. The path might intersect itself. The numbers prescribe how sharp the path in the center of that cell turns. Put in each cell a fitting and correct angle. Each cell with value 1 contains a sharp curve; each cell with value 2 contains a right angle; each cell with value 3 contains a gentle curve and each cell with a 4 is passed straight.
Solution code: The contents of the 2nd and 5th column (after swapping), each top down

Felder statt Kreise in der Anleitung, cells instead of circles in the description; Lösugnscode präzisiert, solution code more precise

I think it is unique, but can't find my solution at once.

Does the division of the diagram into rectangles have to be unique?

Tolles Rätsel - ich persönlich fände allerdings Feldinhalte der ursprünglichen Version etwas interessanter als Lösungscode

:) Sehr guter Einwand. Ich überleg's mir.

Bitte diese Anleitung nicht auch korrigieren. Sonst wird’s nix mit der Fields-Medaille für die endlich doch erreichte Quadratur des Kreises.

Diese beiden fand ich klasse! Danke!
