10 Best 3D Puzzles for Adults in 2022 (Bepuzzled, Ravensburger, and More)

Reviewers were amazed by the detail put into the design of the locomotive and thought it was a joy to build. Even kids found the toy engaging enough to focus on finishing it, without reaching for video games.

This puzzle features unique interlocking pieces that fit together to create a miniature of the famous Sagrada Familia in Barcelona, Spain. Each individual piece is sturdy, well constructed, and very unlikely to break. It even comes with a photography booklet from National Geographic, so you can learn about the beautiful city while you build.

Everything is numbered, either on the piece or the template where you take the piece out from, for easy construction. You could also attempt to put it together without the instructions at first and go back to reference it later if necessary. It's highly detailed and will only take 60 to 120 minutes to piece together.

Some reviewers do mention having to glue certain parts together so they wouldn't fall apart. You will also need patience to build it, as the pieces are rather small and specific. But most reviewers were happy with the results, saying it was engaging, fun to learn about the structure of the building, and very detailed.

Critical reviewers thought the puzzle was very difficult to put together, especially because no instructions were included. Most reviewers, however, really love the beautiful dragon design and the challenge level it offered.

According to reviews, the numbers on the pieces for the buildings are very small and hard to see. You may need to find someone with sharp eyes to help. However, other reviewers loved how you were able to learn more about New York and the order of when buildings were built in the city while you created a final, eye-catching masterpiece.

Reviewers also say that the font on the globe is too small and sometimes the images are out of alignment, so it's not great as a reference for a project. But reviewers like how it stays together without glue, is satisfying to build, and is a great size.

According to reviewers, batteries are not included and the ones recommended by the company don't seem to be the correct size. You will need two 357 watch batteries. The music aspect and the design were a huge hit with reviewers and it was fairly easy to assemble.

Some reviewers were frustrated with the assembly, saying the paper was flimsy and actually did need glue to hold together. The battery box and LED lights were also difficult to access. But it's definitely challenging and takes time but looks great once assembled.

One reviewer mentions that the arms and wings were particularly difficult to put on. You will need a lot of patience to put it all together. But if you are willing to take the time to build it, the payoff is wonderful and it makes a great decoration.

Reviewers found the instructions confusing and some also had pieces missing from their pack. It'd quite difficult to assemble, so it's great for those looking for a challenge. Reviewers suggest using cardboard to hold the structure up and not throwing away any pieces - even if the instructions say otherwise.
