Designer by Mike Snyder and entered into the IPP17 Design Competition this puzzle was made in very limited quantities and is rare so you won't see these sold very often.It is a maze with a twist! Place the ball in one side and escape from the other side - tough but enjoyable.The maze is made from heavy cast aluminum. The diameter of the maze is 3.5" across. The maze has a couple of scratches and light wear as shown in the pictures. The movement is completely smooth.
