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. P.when('A').execute(function(A) { A.on('a:expander:toggle_description:toggle:collapse', function(data) { window.scroll(0, data.expander.$expander[0].offsetTop-100); }); }); Safety Warning Keep away from babies Box Contains 1 x Huzzle Cast Donuts Puzzle See more 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! ## Features - 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 - Hours of fun - Difficulty level 4 ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B076Q9C6CQ | | Age Range Description | 8 years to 99 years | | Best Sellers Rank | 178,739 in Toys & Games ( See Top 100 in Toys & Games ) 159 in Assembly & Disentanglement Puzzles | | Brand Name | EUREKA | | Colour | Multicolored | | Customer Package Type | Flat Free Package | | Customer Reviews | 4.6 4.6 out of 5 stars (337) | | Educational Objective | Concentration Skill | | Global Trade Identification Number | 05407005150573 | | Included Components | No | | Is Assembly Required | No | | Item Dimensions | 12 x 4.5 x 7.5 centimetres | | Item Dimensions L x W | 12L x 4.5W centimetres | | Item Shape | Round | | Item Type Name | "Huzzle Cast Donuts****" Puzzle | | Item Weight | 0.08 Kilograms | | Manufacturer | G3 | | Manufacturer Part Number | 515057 | | Manufacturer Warranty Description | 1 Year Limited Warranty | | Material Type | Steel | | Material Type Free | Plastic-free | | Maximum Age Recommendation | 1188.0 | | Minimum Age Recommendation | 96.0 | | Model Number | 515057 | | Number of Items | 1 | | Number of Pieces | 1 | | Number of Players | 1 | | Operation Mode | manual | | Play Activity Location | Tabletop | | Power Source | manual | | Product Style | donut-shaped | | Puzzle Type | Lock | | Set Name | Donuts | | Size | 12 x 7.5 x 4.5 cm | | Skill Level | Intermediate | | Special Features | Portable | | Theme | Building | | Unit Count | 1.0 count | ## Product Details - **Brand:** EUREKA - **Colour:** Multicolored - **Educational objective:** Concentration Skill - **Included components:** No - **Manufacturer Minimum Age (MONTHS):** 96.0 - **Material:** Steel - **Number of pieces:** 1 - **Product dimensions:** 12L x 4.5W centimetres - **Puzzle type:** Lock - **Theme:** Building ## Images ![Eureka 515057" Huzzle Cast Donuts Puzzle - Image 1](https://m.media-amazon.com/images/I/61vUgPTROqL.jpg) ![Eureka 515057" Huzzle Cast Donuts Puzzle - Image 2](https://m.media-amazon.com/images/I/61reMqVI4CL.jpg) ![Eureka 515057" Huzzle Cast Donuts Puzzle - Image 3](https://m.media-amazon.com/images/I/61rzIATAJ5L.jpg) ![Eureka 515057" Huzzle Cast Donuts Puzzle - Image 4](https://m.media-amazon.com/images/I/91etSICF0JL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Brilliant *by L***M on 13 December 2024* 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.

I love the “cast puzzle series, so very interesting,vexing,frustrating,and satisfying.
