This puzzle is made out of Trespa which is a pressed wood material.
Move the 4 pins through the maze at the same time. This is a very difficult puzzle and will take you a long time to solve it or at least we hope. It takes 4802 moves to solve it but then you get the joy of putting it back to the start again. Yes you read that right, 4802 moves to solve it.
Due to this being a handmade puzzle, there may be imperfections. The solution of the puzzle is still the same.
