Another of Alexander Magyarics clever designs, XYZ Pieces comes with three challenges. This puzzle consists of two set of 6 identical pieces. Each piece is made from 3 half cubes, each on a different axis. Each set of 6 pieces can be formed into a 5x5x5 shape with many holes, but it is still quite a challenge! You can then use 3 pieces from each set to make a third 5x5x5 shape. There are a few solution for each set and 1 solution for the combined pieces. All difficult to find. Each set comes with its own very nice box, unsolved.
