## Description

Product Description Eureka 515057" Huzzle Cast Donuts Puzzle Directions Separate the 2 Donuts and put them back together. Cast Donuts has beautifully shaped rings that look like 2 donuts intertwined together. Try solving the puzzle by imagining the inner structure and using each of the rings’ division lines as a hint. Safety Warning Keep away from babies Box Contains 1 x Huzzle Cast Donuts Puzzle

Review: Brilliant - I got it for my partner who loves the challenge of figuring these kinds of things out and then enjoys others figuring them out too. It took them about 3 hours on and off which on previous similar ones it may have taken 30 mins if I'm lucky so it was a nice change for me and them. It is a nice and sturdy puzzle, it is a bit heavy because it is not hollow metal. I would buy another one of these puzzles of the same level or higher.
Review: Fun and frustrating (but in a good way) - A real challenge! Fun and not that easy - but I found that once you stop thinking too hard, it becomes more instinctive. Pulling it apart was easier than putting it together, strangely enough. The other reviews helped us choose this one. We'll definitely be ordering more!

### ⭐⭐⭐⭐ Vexing and satisfying
*by M***E on 3 May 2020*

Top quality puzzle from Hanayama. I love the “cast puzzle series, so very interesting,vexing,frustrating,and satisfying. Donuts is a great puzzle - I got apart and back together in a couple of days - not on a timer just picking it up now and then. I am sure I wasn’t supposed to use a hammer!!!!! Only kidding.
