This puzzle is very unique in few aspects. First, it is made of only 5 pieces and a wooden frame and still very challenging. Other aspects are that each one of the pieces has 2 layers connected with stainless steel pegs. When you take the pieces out of the wooden frame they can actually turn and look different because of the pin connecting the 2 layers. The objective id to take the pieces out and put them back together inside the wooden frame.
As you understand, you will not need to figure out the right position for each of the 2 layers of every piece to be placed inside the frame and the sequence, moreover, there is an acrylic layer in the wooden frame with channels where the metal pegs can pass, so you need to slide the pieces inside the frame through these channels.
