"Bought for my BIL who is really good at solving puzzles. I bought him a hard one last year that took him about 4 hours. With 300 moves to unlock, all which must be done in a specific order, I was stoked and bragging about this one. He solved it in 15 minutes. I was pretty irritated, but, in his own words, it was his favorite one he has done because it took so much 3 dimensional thought and work to see through it. Irritated it only lasted 15 minutes, but he did say it was his favorite yet due to how much of his brain he had to use 🤷🏻♀️ I would give it less due to cost and time, but he said he'd recommend it, so I'm giving it 5 stars on his request"
