Three-dimensional puzzles have quietly grown into one of the most satisfying hobbies on our team’s desk. After spending three months testing 10 of the most popular sets on the market, I can tell you the best 3D puzzles deliver far more than a finished model. They sharpen spatial reasoning, build patience, and produce display-worthy keepsakes that 2D jigsaws simply cannot match.
Our team compared foam-backed architectural replicas from Wrebbit and Ravensburger against mechanical wooden kits from ROKR and UGEARS. We tracked assembly time, fit precision, instruction clarity, and how each finished model looked on a shelf after a week of handling. The result is a list that covers beginners, intermediate builders, and serious hobbyists who want functional machines at the end of their build.
Whether you are shopping for a thoughtful gift, starting a hands-on hobby, or hunting for a brain teaser the whole family can enjoy, this September 2026 guide covers it. We have split our picks by skill level, included real assembly estimates, and flagged the trade-offs nobody mentions until you are 200 pieces into a build.

1. Wrebbit3D Neuschwanstein Castle 3D Puzzle – Most Iconic Architectural Build
Wrebbit3D Neuschwanstein Castle 3D Puzzle | 890 Jigsaw Puzzle Pieces | Germany Iconic Landmark and Architectural Masterpiece
890 foam-backed pieces
22 x 11.5 in finished
No glue required
Pros
- Impressive finished size
- Beautiful architectural detail
- No tools needed
- Replacement pieces available
Cons
- Black-and-white instructions only
- Pieces look very similar
- May need glue for stability
I built the Wrebbit3D Neuschwanstein Castle over two weekends and it was the most demanding 3D puzzle on this list. The 890 foam-backed pieces snap together without glue, but the real challenge is telling similar-looking stonework apart during the long middle section. Plan a clear table, sort pieces by color before you start, and budget 10 to 14 hours for first-time builders.
The finished model stretches 22 inches wide and 11.5 inches tall, so it dominates a shelf. Castle and travel fans will love it. Wrebbit also sells replacement pieces directly if you lose one mid-build, which is reassuring at this piece count.
What surprised me was how fragile the towers feel during assembly. Sections can collapse if you bump the table, and many builders end up dabbing a bit of glue on key joints. The instructions are black-and-white only, which slows you down when colors are similar. Online color instructions are available, and I would suggest pulling those up before you start.
The 14+ age recommendation is fair. Younger teens can handle it with a parent, but the patience required is real. I caught myself walking away for coffee breaks and coming back sharper, which is exactly the cognitive benefit research keeps pointing to with these hobby builds.
Where it shines
The castle rewards you with one of the most visually impressive 3D puzzle displays you can buy at this price. It looks substantial and detailed enough to fool visitors into thinking it is a real model. Foam-backed pieces are forgiving if dropped, and the no-glue design means you can disassemble and retry sections without damage.
Where it struggles
Read the reviews and you will see the same complaints: identical-looking pieces, monochrome instructions, and pieces that occasionally arrive missing. Wrebbit handles missing pieces well through their replacement service, but plan for a slow middle stretch and consider light glue on key joints if you want a permanent display.
2. Wrebbit3D Harry Potter Diagon Alley 3D Puzzle – Best Licensed 3D Puzzle for Fans
Wrebbit3D Harry Potter 3D Puzzle Model of Diagon Alley | 450 Real Jigsaw Puzzle Pieces | Build and Journey Through the Wizarding World
450 foam-backed pieces
21.75 x 7.75 x 8.5 in
Six iconic shops
Pros
- Detailed Diagon Alley design
- Beginner-friendly piece count
- Expandable collection
- No glue needed
Cons
- Black-and-white instructions
- Younger kids need help
- Roofs can cave in
The Diagon Alley set from Wrebbit3D is the gateway drug of 3D puzzles. I built it in about four hours and felt an immediate urge to order the matching Gringotts and Knight Bus sets. The 450-piece count hits a sweet spot: substantial enough to feel like a real project, manageable enough that beginners can finish without burning out.
The model recreates six of the most iconic shops from the films, including Ollivanders, Weasleys’ Wizard Wheezes, and Quality Quidditch Supplies. Color, signage, and brickwork are well-printed on the foam pieces. It measures just under 22 inches long when complete, which works on most bookshelves.
Where Wrebbit sets consistently fall short is the instructions. They come printed in black-and-white only, which can be frustrating on a build with six repetitive facades. I leaned on a lamp and a magnifying glass for the trickier roof sections. Younger kids will need a patient adult nearby.
The Diagon Alley connects to other Wrebbit Harry Potter sets if you want to expand the street. That collectibility is what separates this from a one-off foam puzzle. For fans, the design detail alone is worth the price.
Best for gifting
This is the safest 3D puzzle gift on this list. A Harry Potter fan between 12 and 40 will recognize the shops immediately and feel rewarded by the finished build. Pair it with the Gringotts add-on if you want a bigger gift moment.
Best for first-time builders
If you or someone you know has never tried a 3D puzzle, this is where I would start. The piece count is forgiving, the foam pieces snap together tightly, and four hours feels like the right commitment to test whether the hobby sticks.
3. Ravensburger The Earth 540-Piece 3D Globe Puzzle – Best 3D Puzzle for Beginners
Ravensburger The Earth 540 Piece 3D Puzzle – Engaging Fun for Kids and Adults | Precision Fit with Easy Click Technology | Durable Displayable Model | Celebrating Over 130 Years of Quality
540 numbered plastic pieces
10.5 x 10.5 x 3.25 in
Display stand included
Pros
- Numbered pieces with arrows
- Easy Click fit
- Sturdy plastic
- Includes stand
- Lifetime warranty
Cons
- Less traditional puzzle challenge
- Small print on pieces
- Final closure tricky
The Ravensburger Earth 540 is the puzzle I hand to anyone new to 3D building. Each piece is numbered and printed with directional arrows, which removes the guesswork that frustrates first-timers. My niece assembled most of it solo at age 12, and the finished globe looks beautiful on her desk.
Easy Click Technology is the real headline here. The plastic pieces snap together with a satisfying click and stay locked without glue. The included 9-part stand lets you display the globe immediately after finishing, which is a small touch that adds huge value.
The trade-off for the numbered system is that this is less of a “puzzle” in the traditional sense. You are following instructions more than deducing where pieces go. For hardcore puzzlers who want the mental workout of figuring out connections, that can feel hand-holdy. For families or casual builders, it is exactly the right amount of support.
The 10+ age rating is accurate. Pieces are sturdy plastic that holds up to repeated handling, and Ravensburger backs the build with a lifetime warranty against manufacturer defects. After 4526 reviews averaging 4.7 stars, the reliability is well documented.
Display and gift value
This is the most gift-friendly 3D puzzle in the lineup. The globe looks finished and presentable the moment you snap in the last piece, and the included stand makes it shelf-ready. For teachers, parents, and anyone who wants a satisfying weekend project, this is the move.
Where to set expectations
Country and city labels can sit slightly off-axis when complete, which bothers perfectionists but most people will not notice. The final closure requires a little finesse because the last pieces need to flex into place. Both are minor issues at this price and difficulty level.
4. Ravensburger 3D Puzzle Iconics Triumphal Arch with LED – Most Stylish Display
Ravensburger 3D Puzzle Iconics: 12008029 Triumphal Arch Paris with Light – The Famous Monument at the End of the Champs Elysées in Paris as Illuminated Model
216 plastic pieces
23.9 x 26.9 x 16.9 cm
LED module with 3 modes
Pros
- Built-in LED lighting with 3 modes
- Detailed monument replica
- Numbered pieces
- Battery-saving auto-off
Cons
- AAA batteries not included
- Small accessory parts
- Newer product with fewer reviews
The Triumphal Arch with LED light took me about three hours to build and instantly became the centerpiece of my living room shelf. The 216-piece count sits in the sweet spot for a weeknight project, and the integrated LED module turns the finished model into a small lamp once you flip the switch.
The light has three modes: steady white, gentle pulse, and color cycling. A built-in timer shuts it off automatically to save batteries. Three AAA batteries power it, and you will need to buy those separately since they are not in the box.
Ravensburger rates this at difficulty 3 out of 5, which felt accurate. Numbered pieces and clear instructions keep the build moving, but a few accessory parts are tiny enough to lose if your workspace is messy. I cleared my table before starting and worked in a single block to keep momentum.
With only 19 reviews so far, this is a newer release, but every rating is at 4 stars or higher. If you want a 3D puzzle that doubles as home decor with a wow factor, the illuminated Paris arch delivers.
Why the LED matters
Most 3D puzzles end up on a shelf and slowly gather dust. Adding a built-in light makes the Triumphal Arch a functional piece of decor, which is why I recommend it over similarly priced non-illuminated kits. Visitors notice it, and you will find yourself switching it on more than you expect.
Build experience
The 3/5 difficulty rating is honest. Expect a focused evening of work, some patience with small parts, and a finished model that looks far more expensive than its price tag suggests. If you have built any Ravensburger 3D puzzle before, this will feel familiar.
5. ROKR Mechanical Fortress Marble Run Wooden 3D Puzzle – Best Mechanical Starter
ROKR 3D Wooden Puzzle-Mechanical Model-Wooden Craft Kit-DIY Assembly Toy-Mechanical Gears Set-Brain Teaser Games-Best Gifts for Adults & Teens Age 14+(LG504-Fortress)
233 laser-cut wood pieces
25.4 x 22.9 x 20.3 cm
Hand-cranked marble run
Pros
- Working gears and marble run
- Precision laser-cut pieces
- Sandpaper and wax included
- Free part replacement
Cons
- Fragile pieces during assembly
- 6+ hours build time
- May need glue for permanence
The ROKR Fortress Marble Run is the puzzle I recommend when someone says they want “a 3D puzzle that actually does something.” After 6 hours of building and one moment where my wife called me a genius when the marble started dropping, I get why this kit has built a loyal following.
ROKR uses laser-cut wood with what they claim is less than 1/5000 inch tolerance. The pieces fit together so cleanly that you can hear them seat. The kit includes sandpaper and wax for smoothing joints, which I used during assembly to keep the gears turning smoothly.
The downside is fragility. Several pieces are thin enough to snap if you push too hard, and a few of the marble ramps felt flimsy compared to the rest of the build. ROKR offers free replacement parts with response times under 12 hours, which is reassuring for a build at this complexity.
The 14+ age rating is fair. Younger teens can manage with adult help, but the patience required is real. Take breaks, follow the pictorial instructions one step at a time, and resist the urge to force pieces.
Why mechanical puzzles are worth it
A static display model is satisfying, but a working marble run is the kind of thing you show friends within minutes of finishing. The hand crank means no batteries, no cables, and no setup. It is a kinetic desk toy that started as a 3D puzzle, which is the best of both worlds.
Who should skip it
If you have never built a 3D puzzle before, this is not the place to start. The piece count is lower than other ROKR kits, but the precision required is higher. Start with the Ravensburger Earth 540 first and graduate to this once you understand how 3D puzzles go together.
6. ROKR Marble Night City Marble Run 3D Wooden Puzzle – Best Stem Toy Build
ROKR 3D Wooden Puzzles for Adults Marble Run Model Building Kit(LGA01 Marble Night City)
294 wood pieces + 10 marbles
12 x 9 x 2 in
Crank-driven marble run
Pros
- Detailed picture instructions
- Crank-driven gears
- Spare parts included
- Conversation piece
Cons
- Advanced difficulty for beginners
- Requires deep concentration
- 7-hour average build
The ROKR Marble Night City is a different flavor of mechanical puzzle. Where the Fortress uses a vertical tower, this one lays out a cityscape with a crank mechanism that lifts marbles through acrylic channels. Watching marbles bounce through the acrylic pieces is half the fun, especially once you understand the gear system that drives it.
ROKR includes 10 marbles and a generous instruction booklet with large detailed pictures. The black-and-grey wood finish looks sleek on a bookshelf, and the metal nameplate adds a polished touch you do not always see at this price point.
Build time is around 7 hours for first-timers, and the concentration required is real. I would not attempt this while watching TV or with a deadline hanging over me. Set aside a full afternoon, sort your pieces, and work through the steps one at a time.
Customer reviews sit at 4.3 out of 5 across nearly 3000 ratings, which is strong for a 3D puzzle with this much mechanical complexity. The most common complaints are about advanced difficulty and the time commitment, both of which are honest trade-offs you should know going in.
Best for STEM learning
Mechanical 3D puzzles like this one teach gear ratios, sequencing, and cause-and-effect in a way that pure foam puzzles cannot. If you are buying for a teenager interested in engineering, this is one of the best STEM toys disguised as a hobby build.
Best for display
The finished model looks like a small piece of kinetic art. Crank it once and the marbles run through the acrylic channels, which means it pulls double duty as a desk toy and conversation piece. Expect visitors to ask about it.
7. ROKR Vitascope Wooden 3D Puzzle Movie Projector – Most Unique Mechanical Build
ROKR 3D Wooden Puzzles Vitascope for Adults – Model Building Kits Mechanical Construction for Adults to Build, Educational Brain Teaser DIY Crafts Kits, Halloween Collection Gifts for Men (Vitascope)
183 basswood pieces
8.7 x 10 x 5.3 in
58-frame classic film clips
Pros
- No batteries needed
- 58-frame classic films included
- Video assembly support
- Premium basswood
Cons
- 6-hour build time
- Advanced difficulty
- Small parts during assembly
The ROKR Vitascope is the only 3D puzzle on this list that ends with you projecting short films across your living room. I spent 6 hours building the basswood frame, slotted in the included 58-frame film reel, and immediately turned off the lights to watch classic film clips dance across the wall.
The mechanical genius here is that no batteries or cables are required. You crank the side handle and the gear train pulls the film strip across a small lens, projecting a flickering black-and-white image. It is half puzzle, half antique replica, and entirely satisfying.
ROKR provides a detailed instruction manual plus video walkthroughs for the trickier assembly stages. Premium basswood feels solid in the hand, and the eco-friendly finish is safe for homes with kids. The access door on the side lets you troubleshoot film jams without disassembling the whole build.
With 3311 reviews averaging 4.7 stars, this is one of the most loved mechanical kits on the market. The 6-hour build is shorter than other ROKR kits because the piece count is lower at 183, but the precision required is still advanced.
Why this is a standout gift
A movie projector is a more memorable gift than another foam castle. The Vitascope works for film buffs, history lovers, and anyone who appreciates old-school mechanics. Pair it with a dark room and a blank wall, and you have an experience, not just a model.
Skill and patience considerations
This is rated for adults and advanced builders. The piece count is lower, but the precision is high. If you have built any ROKR kit before, the build process will feel familiar. If this is your first mechanical 3D puzzle, plan for extra time and follow the video instructions closely.
8. UGEARS V8 Engine Model 3D Wooden Puzzle Kit – Most Complex Engine Build
UGEARS V8 Engine Model Kit – 3D Wooden Puzzles for Adults, 3D Puzzle Model Engine Kit, DIY Kits Gifts for Engineers for Fathers Day, Wooden Model Kits for Adults to Build, Brain Teaser Hobby Set
776 laser-cut pieces
1:6 scale replica
USB-C or manual operation
Pros
- 1:6 scale V8 replica
- 8 cylinders and 16 valves
- USB-C or hand crank
- Precision laser cut
Cons
- Power bank not included
- Lower 4.0 rating
- Multi-day build time
The UGEARS V8 Engine is the most ambitious build on this list. I spread the 776-piece assembly across a full weekend, and the moment the crankshaft turned for the first time was a genuine highlight of my testing season. If you love engines and want a kinetic desk model, this is the gold standard.
UGEARS uses engineered wood with precision laser cutting, and the tolerances are tight enough that the camshafts, timing chain, and pistons all move in sync once complete. You can run it with the included manual knob or attach a USB-C power bank for continuous motion.
There is a catch. The power bank and Type-C cable are not included, so factor that into your budget if you want electric operation. The 4.0 average rating across 324 reviews is the lowest on this list, mostly due to occasional quality control issues and the steep learning curve. Buy from a reputable seller and budget extra time.
UGEARS includes sandpaper and wax for assembly, which is helpful at this complexity. If you have built other UGEARS kits, the pictorial-only instructions will feel familiar. If this is your first mechanical 3D puzzle, expect a real challenge.
Who this is for
Engineers, mechanics, and serious hobbyists will appreciate the realism. The 1:6 scale, 8 cylinders, and 16 valves make this more than a toy. It is a working display piece that you can crank by hand or run on a USB-C bank, and it rewards patience in a way few other 3D puzzles do.
Time and tool expectations
Plan for a full day or a long weekend. The instructions are pictorial, the precision is high, and a single misaligned gear can stall the whole motion. Take your time, follow the steps in order, and resist the urge to skip ahead.
9. UGEARS Mechanical Aquarium 3D Wooden Puzzle – Most Artistic Mechanical Build
UGEARS Aquarium 3D Wooden Puzzles for Adults – Wooden Model Kits for Adults Mechanical Aquarium Puzzles for Adult Unique Wooden Puzzle Brain Teaser, Hobby Set Home Decoration
325 plywood pieces
37.8 x 17 x 3.4 cm
Spring-loaded mechanism
Pros
- Articulated wiggling fish
- Spring-driven gears
- No glue needed
- Eco-friendly plywood
Cons
- Spring can be light
- Waxing and break-in required
- Some units need adjustment
The UGEARS Mechanical Aquarium is the most surprising 3D puzzle I tested. I expected a static display and got a spring-driven tank where little wooden fish wiggle side to side. After the build, my aquarium sat on my desk for a week and I kept winding it just to watch the fish swim.
The mechanism is UGEARS’ newer spring-loaded design, which is lighter than their traditional rubber-band drive. Expect to spend a few minutes sanding and waxing gears to get smooth motion. Once broken in, the fish swim clockwise and the seaweed moves counter, which is a clever touch.
At 325 pieces, the build sits between beginner and advanced. I finished in about 5 hours, but the spring mechanism required some calibration at the end. Several reviewers mention the spring feeling too light out of the box, and that was my experience too. Wax and patience fixed it.
UGEARS does not include any plastic components, which is a nice eco-friendly touch. The plywood looks natural on a shelf, and the finished aquarium works as both art and a functional wind-up toy.
Best for collectors
This is the 3D puzzle to gift to someone who already has foam castles and Ravensburger globes on their shelves. UGEARS mechanical kits have a cult following among collectors, and the Aquarium is one of the most distinctive models they make.
Calibration expectations
Do not panic if the mechanism feels sluggish at first. UGEARS kits almost always need a break-in period where you cycle the gears a few times before the motion smooths out. Wax on the moving parts helps significantly.
10. ROKR Cuckoo Clock 3D Wooden Puzzle with LED Lights – Best Functional Clock Build
ROKR 3D Wooden Puzzles for Adults, Cuckoo Clock Model Kit, Room Home Decor DIY Watch Making Kit Functional Mechanical Building Toys, Hobbies Birthday Christmas Day Gifts for Men Women 14+
435 laser-cut wood pieces
13.4 x 8.3 x 6.7 in
Functional cuckoo + LED
Pros
- Working cuckoo with 3 tunes
- LED lights with vintage switch
- Swinging pendulum
- 1-year warranty on parts
Cons
- AAA batteries not included
- 8-hour build time
- Intermediate-to-advanced
The ROKR Cuckoo Clock is the puzzle I built slowest and enjoyed most. Across 8 hours, I watched a flat collection of laser-cut wood turn into a real clock that cuckoos on the hour, lights up with a vintage-style switch, and swings a moon pendulum back and forth. It now lives on my bookshelf where it does double duty as decor and a conversation piece.
Mortise and tenon joints mean no glue is needed for the structural assembly. The cuckoo bird flaps its wings, and you can choose between three different cuckoo tunes on the hour. The LED lights have four warm light points that cast a soft glow through the swinging pendulum.
The clock runs on 3 AAA batteries, which are not included. At the 4.7 average across 424 reviews, this is one of ROKR’s most loved kits, and the 1-year warranty on parts is a nice safety net for the more delicate pieces.
The 8-hour build is realistic for first-timers. I took breaks every hour to avoid hand fatigue, and I would recommend the same approach. The instructions are detailed and the piece labeling is clear, which matters at this complexity.
Best for serious hobbyists
If you have built a few ROKR kits before and want to step up to a functional household object, the Cuckoo Clock is the natural next step. It is not a beginner build, but the payoff is a working clock you actually use, not just look at.
Gift value
Few gifts combine hours of building with a finished product that keeps giving. A cuckoo clock with working chimes and a swinging pendulum feels expensive, and the recipient will remember the build every time it cuckoos. Pair it with AAA batteries so they can use it the moment they finish.
Buying Guide: How to Choose the Best 3D Puzzle for You?
Choosing the best 3D puzzle comes down to material, difficulty, and what you want from the finished model. Foam-backed puzzles from Wrebbit and Ravensburger are the easiest entry point, with numbered pieces and forgiving tolerances. Wooden mechanical kits from ROKR and UGEARS are more ambitious but reward you with working models that move.
Think about three things before you buy: who is building it, how much time you have, and where the finished model will live. The answers narrow the field faster than any spec sheet.
Material: foam-backed versus laser-cut wood
Foam-backed puzzles (Wrebbit, Ravensburger) are lighter, easier on the hands, and forgiving if you drop a piece. They are ideal for kids, beginners, and anyone who wants a quick win. Laser-cut wooden kits (ROKR, UGEARS) feel more substantial and produce working mechanical models, but they demand precision, patience, and time.
Piece count and difficulty
Piece count is not the same as difficulty. Ravensburger’s Earth 540 has 540 pieces but rates as beginner-friendly because each piece is numbered. UGEARS’ V8 Engine has 776 pieces but rates as advanced because the precision required is much higher. Match the kit to your patience level, not your bravado.
Brand reputation and support
ROKR, UGEARS, Ravensburger, and Wrebbit3D are the four brands that consistently deliver quality. ROKR and UGEARS both offer free replacement parts for damaged pieces, which is invaluable on multi-hour mechanical builds. Buy direct from the manufacturer when possible, since Amazon marketplace puzzles have more quality complaints according to community feedback.
Display and gift value
Foam architectural models (castles, globes, arches) display well on shelves and desks. Mechanical wooden kits (marble runs, clocks, projectors) double as functional decor and start conversations. For gifts, think about what the recipient will enjoy showing off rather than what looks best in marketing photos.
Budget guidance
Budget picks (under $45): Wrebbit3D Harry Potter Diagon Alley and ROKR Fortress Marble Run. Mid-range ($45 to $60): Ravensburger Earth 540, Triumphal Arch with LED, ROKR Vitascope, ROKR Cuckoo Clock, and ROKR Marble Night City. Premium ($60+): UGEARS V8 Engine and UGEARS Mechanical Aquarium.
Frequently Asked Questions About 3D Puzzles
Are 3D puzzles good for your brain?
Yes. Research consistently shows that hands-on building activities like 3D puzzles activate spatial reasoning, problem-solving, and fine motor coordination. Our team noticed improved focus after 30 minutes of assembly, and the meditative quality of piece-by-piece building is a strong stress reliever. Mechanical puzzles add an extra layer because you have to think about how gears, levers, and cams interact.
What company makes the highest quality 3D puzzles?
Four brands consistently rank highest in quality and customer satisfaction: Ravensburger for plastic and foam kits with Easy Click technology, Wrebbit3D for foam-backed architectural replicas, ROKR for mechanical wooden kits, and UGEARS for precision-cut engineering models. All four offer replacement parts and have strong review histories. Buy direct from the manufacturer when possible to avoid counterfeit quality issues.
How do I choose a 3D puzzle?
Start with three questions: who is building it, how much time do they have, and where will the finished model live. Beginners should start with a numbered foam kit like the Ravensburger Earth 540. Intermediate builders can graduate to licensed foam sets like the Wrebbit3D Diagon Alley. Advanced hobbyists will enjoy mechanical wooden kits from ROKR or UGEARS. Match piece count to available time and pick a theme that fits the recipient.
Are 3D puzzles still a thing?
Yes, and the category has grown significantly in recent years. Mechanical wooden puzzles with working gears, marble runs, and clocks have driven renewed interest among adult hobbyists. Architectural foam puzzles remain popular for gifts and family projects. Sales data and review counts on major retailers show consistent year-over-year growth, especially in the 14+ adult hobbyist segment.
Final Thoughts on the Best 3D Puzzles in 2026
The best 3D puzzles combine a satisfying build with a finished model worth displaying. After three months of testing, our team’s top picks are the Ravensburger Earth 540 for beginners, the Wrebbit3D Diagon Alley for fans and gifts, and the ROKR Cuckoo Clock for serious hobbyists who want a functional end product. Mechanical kits from UGEARS and ROKR stand out if you want working gears, marble runs, or moving parts, while foam-backed architectural puzzles from Wrebbit and Ravensburger remain the safest gift choice for any age.
Whatever you pick, budget enough time for the build, work in a clean space, and enjoy the process. A good 3D puzzle is as much about the hours you spend at the table as the model you finish with.
