ROKR 3D Wooden Puzzles for Adults Marble Run Model Building Kit(LGA01 Marble Night City)

This thing was so fun to put together. I have big meaty sausage fingers so I found it a bit difficult in some tight spots but I managed. I broke one small piece that I had to glue back on and I had to sand down a couple of places to get the marbles to move a bit more smoothly. Other than that it functions great. Its such a cool thing to have and everyone that comes over plays with it. This was well worth the price.

While this is definitely not for kids, I really enjoyed putting it together. The pieces are very accurately cut and well-marked. You have to be careful not to break them, some a pretty fragile. Once you get acquainted with how things go together it isn't a problem. I broke a couple of pieces, but they were easily repaired with some wood glue. The instructions are all pictures and some were a little small, but I took a pic with my phone and zoomed in to figure those out. There are also some videos that help (QR codes in the manual direct you to the videos.) There were a couple of times that i tried to make something work before completing the assembly and was worried that things didn't align properly, but later steps in the assembly fixed every issue. If you are impatient, or have trouble following instructions closely, this isn't for you, but I loved it. I ordered my second one just a few days after completing the first one. Highly recommended.

The media could not be loaded. I really enjoyed this one but found this one more frustrating than Spaceport. I broke more peices than on the other. There are some spots I need to fix and I'm going to connect it to the other with the link package. I'll update when I do

The media could not be loaded. This marble runner is an absolute hit! While it’s designed for kids, even adults will enjoy assembling and experimenting with it. The quality of the pieces is excellent, and everything fits together smoothly. It’s a great way to introduce children to basic physics concepts like gravity, motion, and energy conservation in a hands-on, engaging way.Watching the marbles navigate through the maze is both fun and educational. It encourages problem-solving, creativity, and patience as kids figure out different track design.Overall, this is a must-have STEM toy that combines learning with endless entertainment. Highly recommended for any child who loves building, experimenting, and having fun!

This is a 5 star product for me. I did break two pieces, some of the pieces were very difficult to push together, and it doesn’t work perfectly every time. I did also use a little super glue in a few pieces. However, the design of sending a few sheets of balsa wood, to make something like this had my wife and I blown away. It’s super impressive… I thought my 5 year old and I could do this together, not for kids lolSome comments reference a few of the issues I mentioned as reasons for knocking off stars, it’s a delicate, very elaborate, balsa wood marble theme ride… it’s not made of plastic and it’s not supposed to be a quick throw together project. The fun is in the assembly. So carve out a few nights, or weeks and enjoy this marvel!Thanks for a challenging and fun build. Highly recommend.

What an awesome piece of fun! The instructions were awesome and easy to follow. The pieces were well made. I didn't have to use but a few of the extras. It works great. This is up there at the top of my list of marble runs to make and enjoy!

The marble run/puzzle was fun to put together, and it's a great concept. However, the materials are quite flimsy and do not always fit together properly. Sometimes you have force it a bit, then glue it in place. I think they would be better off with larger and sturdier materials, even if it made the marble run bigger. (They do send spare parts with the set, but not always the part that you need after breaking it (flimsy). Again, it was fun, but being so flimsy it doesn't work properly and just needs to go in the trash.

I thoroughly enjoyed putting this puzzle together. This is not for beginners. There are a lot of small and moving parts, as well as metal rods and plastic washers. The quality is very good, however some of the tracks did not line up perfectly causing the metal marbles to get stuck.Despite it not being fully functional, I built this to display and not to play with. Fun project that took about 7-8 total build time. The two-tone colors are great too and give it a nice visual appeal.
