Instructions

   

Draw a domino snake into the diagram, that doesn't touch itself not even diagonally. The snake starts at one of the two fields marked with a circle and ends in the other one.

The snake consists of the domino stones from '1'-'1' to 'n'-'n', that have to be arranged in a way that only halves of domino stones with same numbers touch. Every domino stone is used exactly once.
