A great display piece too. Would highly recommend. Great puzzles from the maker.Mike ✌🏻 ### ⭐⭐⭐⭐⭐ Great puzzle! *by K***M on February 4, 2020* I bought this for my husband for his birthday- while it is a little smaller than I expected, it’s a beautiful puzzle and makes for a great decorative conversation piece.It took my husband a little over an hour to solve and a half hour to put back together. I was able to solve it in just under an hour, but it took about an hour and a half to put it back together (you’re more likely to accidentally solve it again than get it back to starting)!Our family were all pretty captivated by it as well- everyone wanted to fidget it with while visiting and loved how it looked!I highly recommend this for anyone who loves a good puzzle! ### ⭐⭐⭐⭐⭐ Feels so good to solve! *by R***L on January 2, 2022* It took me about an hour to solve but once you get the pattern, it's so exciting to start moving everything with purpose. Once you solve it, it takes maybe 5-10 minutes to reset it and do the pattern in reverse. The only sad part is now the secret is ruined and it's not as fun to play again, but fun to watch others try! --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/155989514-project-genius-constantin-double-trouble-wooden-puzzle-dual-maze-brainteaser](https://www.desertcart.us/products/155989514-project-genius-constantin-double-trouble-wooden-puzzle-dual-maze-brainteaser) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-16*
