Beautiful puzzle that is challenging
What a tricky brainteaser! I bought this as a Christmas gift for my husband who really enjoys brainteaser puzzlers. It is difficult enough to keep him occupied and fun enough to make him come back to it again. The craftsmanship is really nice, and the seller is very prompt and communicative. I would definitely buy from Creative Crafthouse again. Recommended for: brainteaser fans, puzzle fans, high difficulty level, people who enjoy well-crafted wood puzzles

Great gift
Very nice gift. Wood is soft. It comes as shown. No box. Be aware that instructions are inside so better open plastic seal and take them out so there is no temptation. This was a gift. The person trying to solve it invested a whole afternoon and could solve it by himself. It was solve in another half an hour with some help. I guess it could have been solved in a whole day with more patience.

This is a fun puzzle. Took about four hours over 2 days
This is a fun puzzle. Took about four hours over 2 days. I did find that there are at least 2 different ways to solve it, not 1. My mom did it separately from me and we both took pictures of our solutions and they were different and both worked perfectly.

my son the puzzle man
after reading the reviews my wife thought this is the one my son won't get, I told her he would have it done before we left to go home, it took him less then an hour, this is a good quality well made wood puzzle not sorry at all I got him this for Christmas it did challenge his mind, and no he's letting people see the answer if the maker needs to see to believe I'll have him send a picture. happy costumer :)

It's plenty hard to figure out...
I bought this for a friend who was bed ridden after surgery. That was a month ago and he still hasn't solved it (and he's a tech guy)! A young woman who visited him spent hours and so far, has been the only one to figure it out. It's beautifully crafted - the wood is sanded and finished. We leave it out for visitors to play and they love it!

Excellent Brain Teaser
I have a SIL and granddaughter with borderline genius IQ’s. This is a great puzzle to find for someone who you really want to challenge!
