3D Pentomino Chess Cube Puzzle
Packing puzzles can challenge even the most experienced puzzlers! The 3D Pentomino Chess Puzzle is one of the hardest packing puzzles we have in our collection. This puzzle takes the game to another level with 25 identical Y-shaped pieces that all must be packed into a 5x5x5 cube. Unlike many puzzles, there is more than one solution to the Pentomino Cube; but, there is only one solution that forms the cube with a perfect, checkered pattern (inspired by the classic Chess board).
