For more info please visit: https://kubiyagames.com/products/diamond-cube-1-wood-puzzle The Diamond Cube 1 is made of 12 uniquely shaped pieces that fit together into a cube. Pay attention when you trying to take the cube apart, as most burr puzzles have one key piece that must be removed first to unlock the rest of the pieces, and put in last when you’re re-assembling the cube. The Diamond Cube 1 has precise steps that you have to follow to solve the puzzle. Perfect for building focus, patience, and spatial reasoning!
