There are 4 identical but very unusual shaped pieces to fit inside the square cage. To remove the pieces you'll need to complete the unique level 18.104.22.168 solution.
An interesting design with lots of movement; this is a good 'doable' puzzle for the puzzler who's never done many of these puzzles before. 'Doable' in no way translates to easy in this case but a nice puzzling experience.
Designed in July 2013 by Tamás Vanyó from Hungary and beautifully made by the guys at the Pelikan workshops. Very smooth action and feels lovely in your hand.
Woods used: The cage is made from 1. Wenge (black) or 2. Bubinga (brown) with Maple pieces (white)Size: 85mm x 85mm x 60mm
