Chocolate Factory – Wooden Marble Run Kit

Brandon L.

I enjoy building things like this and uploading each step of the build to my TikTok, these are always entertaining to me to build and have fun with and show off to friends and family.

Surprisingly good quality. Thick boards with an exception of a single board that was needed for specific parts. No warping of boards at all. Metal axes and no toothpicks whatsoever. Lighting harness held up to lots of bending and twisting and never broke. All the cuts were precise and parts came off without issue.Engineering and design are also top notch. Lots of functional gearing throughout the base of the model. I really enjoy kits that have functional mechanics as this one does. The first half of the build is assembly of the mechanism with the second half being more of the aesthetics. All the lighting is nicely recessed, and the battery compartment is so over engineered it makes me smile to play with it.The use of colored parts is a welcome addition as I grow tired of all the painting I've been doing on other models. The final product has a high quality look to it without any customization. I highly recommend this kit.

I have not put this item together yet, but I will make some initial comments. First, the box is super cute and the items are well packaged. The wood pieces are sealed in plastic and the additional components that make the device move seem to be in good condition. There is an instruction manual that lays out all of the items in photographic detail which is going to be imperative because as my headline suggests, the instructions were not written in English. It was VERY clear that these instructions were written in some other language and then poorly converted to English. I will be relying VERY heavily on the images for each step (which thankfully there appear to be plenty of throughout) to put this together. I do worry about the size of the images and where each component goes, but I think I can probably take photos with my phone and enlarge anything I can't see too well when I start constructing it. Be prepared to have sandpaper and a screwdriver on hand, based on what I noticed at first glance through the book. There is a QR code to watch the carousel in action and I highly recommend this if only for the motivation to put the thing together.Will update on difficulty of construction after I've had the chance to put it together.

This is another fine wooden kit from ROKR, It’s a level 4 and this one requires 2 CR2032 Batteries to function. It Has a well illustrated instruction book and all parts are labeled. There are included spare parts so that you can continue if you loa=se or break some part. . There is a page with illustrations of all the non wooden parts and the associated part number.

This was my first puzzle of this type an I found it very easy to put together. Not one piece broke an it’s very sturdy, I found that out after the finished model got knocked off the table. Marbles run perfectly thru without getting caught up. The lights are a nice touch. I love this model. I’m 55 an can’t help but play with it every time I go by it lol

The media could not be loaded.  First of this type of project for me, instructions are very clear an parts fit perfectly together. I’d say if I kept at it it would take around 8 hours to put together.

Pros:BeautifulFun to assembleCons:Gears didn't line up for usMoving parts inaccessible once builtMy 12 year old son enjoyed building this. But about two thirds of the way through it became obvious that some of the gears weren't lined up properly and the marble run wasn't going to work when cranked. We tried adjusting some of the gears, but they were deeply covered by other parts at this point. The directions need a better way to tell you if each section is put together properly before you move on to the next section. But so many of the moving parts are put together before you can really test it. Our choices were to disassemble the entire thing, try to remove the bottom, or give up and have a non working hand crank / marble run. We tried to remove the bottom but that was not going to work. I think the design should have allowed better access to the moving parts once assembled, like a hatch on the bottom. We ended up giving up on the marble run and we have a decorative Chocolate factory.Because it's hard to get the gears working properly, I wouldn't give this as a gift to someone. Finding out that you didn't get the gears installed quite right was pretty discouraging. My son stopped building it for a few days straight before starting up again.Overall there was a lot of time enjoyed building the marble run.

I took this puzzle to my office as a fun distraction to work on during breaks. It brought my coworkers together, since they all thought that the puzzle box was a chocolate box. They were a bit disappointed when they opened it and found a wooden puzzle instead.This puzzle has 400+ pieces, some of which are small and require patience to handle. Each piece is labeled with a letter and number, so it’s easy to identify which parts you need for a particular step. There is a tool included for measuring and pushing the pieces in place. Popping the pieces out of the boards is easy, and none of the pieces came out broken or cracked. The instructions are easy to understand and each step is accompanied with a picture.Completing the puzzle is time consuming and I haven’t had the chance to finish it, but I will update with a picture once I do.

This was a lot of fun to put together. My fingers definitely hurt a lot when I was done, but it was worth it. I did check to make sure that the gears could turn before I put the pieces together, but in the end it didn't really turn correctly, which is fine because I'm just using it as decoration. I like putting together legos, so this was a nice alternative to that. The only thing I would say badly is that it didn't have the batteries included like it says that it does. So I can't see how it looks with the lights on. I'll have to buy some batteries to put in so that I can do that.

I've got this about half done, and it definitely takes some effort, especially for someone with big hands and weak eyes. I'm enjoying it, though. I've only broken one part- they're a little more sturdy than balsa, but not much- and it was missing the button batteries for the lights, but these aren't deal-breakers. It is very cleverly designed. There is a fair amount of gearing in the bottom, and it's all running smoothly. The instructions are mostly understandable, and well=paced, but they occasionally forget to reference a part. If you have the patience, or like putting things together, this is an awesome kit.

The media could not be loaded.  I love wooden puzzles. Usually, I can get through them pretty easily. This one, while I love the end results, was a pain to assemble!Some of the instructions didn’t make the translation to English well, and it caused some confusion at some parts. There were parts of the instructions that didn’t apply that were also confusing. For example, I spent 15 minutes trying to “peel protective layer from both sides” of a thin plastic circle before I came to the conclusion, it had no protective plastic!The assembly itself was a bit rough. Some parts really needed to squeeze into place. It does come with a lot of spare parts for the tinier pieces, which is good, but it doesn’t say exactly WHAT parts are extras. I snapped a couple pieces during inserting, and just stuffed the broken piece into place as I didn’t know if THAT particular piece had a spare (turns out, it did).Otherwise, this thing is SOLID!!! The pieces do fit together snuggly, but this is also the only wooden puzzle I’ve assembled that requires no glue whatsoever! I’m actually really impressed with the level of engineering that went into this piece!If you have the time and patience, this is a great puzzle to own! The end results are amazing, and I highly recommend it! It’s just not for beginners or young children, in my opinion.

Talk about a very unique and awesome model! I am not exactly a steampunk fan, but really liked how this looked and more so, what it does. I figured my grand kids would have so much fun with it. Everything comes packed very well, much better than many products I see.the instructions are VERY detailed, have not had a problem so far. Be warned though, there are SO, SO MANY parts to this one. Not saying that is a bad thing, just saying, be prepared to spend some time on this one and you probably should have a dedicated space to put it together as it will likely take some time to assemble it. Even though there are many pieces, everything is labeled well so you should not have any issues.I have not fully assembled it, hard to find the time, but I am chipping away at it and I'll be sure to post some more pictures and should be able to post a video.Such an amazing kit, price is very fair, would gladly recommend!

This wood puzzle was fun to do.The instructions were easy to follow and it comes with great picture illustrations that helped with the assembly.The wood material is thick, its easy to detach from the board and easy to fit together.The colored wooden parts are well painted and looks good.It comes with the included tools to make the assembly much easier, and all pieces are well numbers for easy identification.The mechanics work well with no issues.Overall a great quality and fun puzzle.My daughter and I loved it.

The media could not be loaded.  I have assembled a lot of these wooden puzzles, lots of different styles and different brands. Prior to this model Rokr was always one of the best. The Chocolate Factory really fell short of my expectations. There were multiple holes that didn't line up properly. It was missing batteries, not a huge deal but annoying. There were so many extra parts I thought I missed some steps. Once it was all assembled I was very disappointed with the movement, it is not smooth, the marbles get stuck and a lot of the moving details are hidden. It was fun to assemble, I probably spent 15+ hours over multiple days putting it together. Current list price is $59.99 at the time of this review, this is about average for a model of this size/complexity but the function doesn't live up to my expectations based on other models from this brand.
