We scoured the internet and pored through reviews to find the best 3D puzzles for adults. We looked at puzzles in wood, crystal, and foam; they were shaped as castles, pirate ships, and dragons. Along the way, we found that the best match what you’re looking for in terms of design, complexity, and size.
Generally speaking, the hardest puzzles have more pieces, include moving parts, and come with detailed instructions. Keeping all these things in mind, we hand-picked a few that could double as works of art or feats of engineering.
Top 10 Best 3D Puzzles for Adults to Buy Online
Picking out a puzzle that appeals to you is naturally a subjective task. The ones we’ve chosen are high quality, fairly difficult, and good looking.
1. UGears Mechanical Models Mechanical Steam Locomotive
Best Highly Complex Puzzle with Moving Parts
This puzzle kit allows you to build an intricate moving locomotive powered by rubber bands. It features details like functioning doors, a retractable ladder, and an art-deco trim.
Because of its complexity, you’ll likely have to follow the instructions pretty carefully to get it right. But don’t worry, it’ll still be quite the challenge and will take about 12 hours of constant work to complete.
|Size||12″ x 3.9″ x 4.9″|
2. CubicFun St. Basil’s Cathedral
Best Architectural Puzzle to Build with or without the Instructions
This puzzle features unique interlocking pieces that fit together to create a miniature of the famous St. Basil’s Cathedral in Moscow. Each individual piece is sturdy, well constructed, and very unlikely to break.
Each piece is numbered 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.
|Size||16.1″ x 12.6″ x 21.3″|
3. Bepuzzled Crystal Dragon Puzzle
Best Crystal Puzzle for Decor
This dragon puzzle is rated a level 3 out of 3 and, despite its low piece count, takes several hours to put together. You have the choice of downloading the instructions, but it can still be quite the challenge due to all of the pieces looking so similar.
Unlike most crystal puzzles, this one features moving parts, which could make the puzzle a fun decoration once it’s been completed. Should you have any issues with missing pieces, the manufacturer is very responsive.
|Size||5″ x 8” x 5.5”|
4. 4D Cityscape New York City Skyline
Best Puzzle that Teaches as You Build
This unique product features three distinct levels of puzzling–a flat base, a 3D foam layer, and over 100 buildings and architectural features to fit into place.
It comes with a guide that will tell you what order to put the buildings in, giving historical background on each and showing you how New York has developed over the years.
|Size||28″ x 12″ x 4″|
|Extras||Interactive history lesson|
5. Ravensburger The Earth
Best Practical Puzzle that You Can Actually Use
This puzzle builds a to-scale, fully functioning globe and even includes the stand. Its plastic pieces are sturdy and really lock into place, removing the need for any glues or adhesives.
However, because it’s a sphere, the only way to really put it together is by building it from one side to the other, which, if you’re putting it together with a child, may not provide the best geography lesson.
|Size||8.7″ x 8.7″ (minus the stand)|
6. Robotime Orpheus Music Box Robot
Best Multi-Functional Wooden Puzzle
This almost seems more like a robotics project than a puzzle. It features a wind-up music box, lights, as well as moving arms and legs. Each piece is laser-cut and fits together perfectly, and although sandpaper is included, you probably won’t use it.
Because some pieces need to be glued together, you need to be careful about reading the instructions to ensure that you’re not gluing moving parts. It might also be a good idea to buy a glue that dries faster than the one that’s included.
|Size||5.9″ x 3.6″ x 7.3″|
|Extras||Moving parts, lights, music box|
7. CubicFun 3D Pirate Ship
Best Large Puzzle with Lights
Standing over two feet tall, this puzzle is on the larger side, though it isn’t particularly complex. It comes with numbered pieces, and if you use the instructions, it should take about six hours to put together.
This ship also includes LED lights, which makes for a great display. The pieces fit together very tightly (a bit too tight sometimes, according to some reviewers), and it does not require glue for stability.
|Size||26.65″ x 10″ x 25.2″|
8. Bepuzzled Tinkerbell Crystal Puzzle
Best Crystal Puzzle for Disney Lovers
Although this puzzle is rated level 1 (out of 3), it’s more difficult to put together than you’d first expect and requires a reasonable amount of patience. Each piece snaps together nice and snug, and you don’t have to worry about it falling apart.
For Disney fans out there, this company also produces a whole range of other Disney character puzzles to add to your collection once you’ve finished this one.
|Size||3.6″ x 2.9″ x 5.4″|
9. Wrebbit 3D Hogwarts Astronomy Tower
Best for Veteran 3D Puzzle Builders
For those looking for a traditional puzzle experience but 3D, this could be the one for you. It does come with some instructions to help you understand the structure, but you’re left largely on your own.
This isn’t a puzzle for beginners as many pieces look almost identical, and there are even some additional spacer pieces thrown in that aren’t part of the finished product.
|Size||15.5″ x 12.75″ x 19.25″|
10. Wood Trick Wooden Robot Hand
Best Working Mechanical Puzzle
This puzzle creates a fully functioning mechanical hand. It requires close attention to the instructions to ensure that you’re sanding all the right areas so that it moves properly.
However, as it’s made out of wood and held together with toothpicks, it won’t be incredibly sturdy and should be used more as a display piece than a toy.
|Size||20.5″ x 10.6″ x 4.4″|
How to Choose a 3D Puzzle for Adults – Buying Guide
Aside from how the finished product looks, these are the factors to keep in mind when choosing a 3D puzzle.
Puzzle Type Determines the Look and Shape
There are three main types of 3D puzzles: jigsaw, wooden, and crystal. Each has different visual characteristics, and deciding on a type should be one of the first things you do.
Jigsaw 3D puzzles are generally made from cardboard, foam, or plastic and feature typical “puzzle pieces” with interlocking sides and printed designs. These tend to be the most versatile, with the widest range of designs.
Wooden puzzles generally come unfinished, which allows you to leave it as is or paint it for a custom look. Mechanical and geometric designs often fall under this category.
Crystal puzzles are clear plastic pieces that fit together precisely to create a 3D shape. These often have fewer pieces but may still take a long time to figure out as many of the pieces can look the same. Crystal puzzles often take the shape of animals or items.
Make Sure You Have Enough Space to Build and Display
For many people, doing a 3D puzzle is meant to be a days-long effort, so it’s important that you have enough space to accommodate not just the finished product but also your mid-process puzzle for as long as you need.
As fun as it might be to build a 3-foot pirate ship, if it means displacing your family from the dining room table for a month, you might want to consider something smaller. If you’re planning on displaying it, you should also be sure to check that the finished product fits within the space that you have.
Judge Complexity by the Number of Pieces
Generally speaking, the more pieces a puzzle has, the more complex it’s going to be, and the longer it’s going to take.
While there are some notable exceptions—if a puzzle consists of 100 nearly identical pieces, for example—piece number gives you a pretty good gauge of how long a puzzle might take you. Don’t forget to consider your attention span as well as your tolerance for frustration when considering how complex of a puzzle you’re looking for.
Think about Whether or Not You Want Instructions
If you want to figure it out on your own, then you can get a set that has zero instructions.
But it sucks to have a half-finished puzzle lying around for the rest of eternity, so consider getting one with instructions to use as a cheat sheet. You always have the option of not looking at it until you’re ready to. Puzzles that come with instructions also tend to be more difficult, which could mean more fun too.
If You Plan to Display It, Consider Looking for Puzzles with Lights or Moving Parts
Some people construct puzzles just for the fun of the build and break them down again after. Others prefer to keep their finished pieces on display.
If you’re the type that prefers to display your finished product, it might be worth looking into puzzles that have working lights or moving parts. These extras can make a puzzle a bit more difficult, but it can also make it a much more interesting display.
How to Glue a 3D Puzzle Together
If you’re hoping to immortalize your completed piece, you might want to consider adhering the pieces together. However, when you’re dealing with a 3D structure, it’s a bit harder than gluing together a regular flat puzzle.
For puzzles with foam pieces, it might make sense to use pins at the edges rather than glue. This will hold the sides together while giving you some leeway to take it apart in the future.
For other types, it makes more sense to an adhesive. But rather than using a spray adhesive as you would with a 2D puzzle, you’ll get a stronger hold with an adhesive that you apply between each piece. As you’ll be gluing as you go, look for a quick-drying craft glue so that you don’t have to slow your building pace too much.
Looking for Some More Ways to Pass Time? How about These Products?
We know about some other really cool toys to play with; it wouldn’t be nice if we kept all this knowledge to ourselves, would it?
Puzzle building is a fun, focused task, and 3D puzzles are especially so. But even if you get the best puzzle available, it’s no use if you don’t finish it. So always keep your own abilities and preferences in mind when making your choice, and remember, it’s all about having fun.
