This puzzle is not your traditional maze puzzle. Remove the transparent acrylic cover from the top of the puzzle, and you will see that there are 18 different pieces that compose a 2-layer maze. Your goal is to arrange them into the correct formation so that you can successfully navigate the ball from start to finish. This is a very difficult puzzle!
