First one was defective. The second one worked but was confusing to figure out what was expected. Also he solved it quickly.
there was nothing great about the product. my boyfriend shifted one square counter clockwise and the whole puzzle went black. all it took was literally one move, which was the first move to " solve " the puzzle. it was nothing like the advertisement video. the charger was loose, and had to be held a certain way to stay put. this wasn't fun or challenging. don't make the same mistake I did and waste almost $100 for no reason. not sure how to contact customer service, but we are not happy . this was a scam
