The flight game(Flygspelet)

Really hard level sliding puzzle!This puzzle requires careful planning and strategic thinking. The goal is to move the tiles around so that the airplane reaches the lower right corner. Thread the holes to M3 and use countersunk M3 screw (max 15 mm). The metal plate on the picture is 162x132x1 mm. You can of course use other materials. I learned this game from my grandmother quite a long time ago.She taught me how to solve this game but unfortunately, to day, I don't remember how she did this!A tip is to let the two squares stay close to the aircraft. Have fun and don´t get crazy! :)
