Review on Unveiling the Original 3D Crystal Puzzle Deluxe: A Must-Try for Puzzle Enthusiasts! by Greg Horn

There were NO printed instructions in the box. I had to go online and print out instructions which didn't help much. Just shapes and numbers, no help. The pieces don't fit together very well, hardly sit together, so if you have young children and want to work on them here and there while they sleep or are busy, then move them out of the way while you have them back. There won't be time, forget it. Even YouTube tutorials don't match the printed images and numbers. This is an absolutely horrible design, I unfortunately ordered 3 of these this Christmas season and I feel completely betrayed and I feel so sorry for the people I gifted them to. to!
