ROKR3D Wooden Puzzles for Adults Marble Run Model Building Kit(LGA01 Marble Night City)

Easier than I thought it was going to be.

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!

Easier to construct when the instructions were clear, otherwise it’s a true puzzle. I couldn’t get it to work as pictured but rigged up a fair workaround. It says glue is not needed, but it doesn’t hurt either, and I used it when I was sure of the correct fittings.

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!

very good

This is not my first Rokr puzzle, and while I did find it difficult, as long as you follow the instructions carefully (very carefully) this is a fun and mostly fulfilling project. However, I like many other reviewers on here are experiencing marbles getting stuck on the track. I wonder if others are having the issue in the same location as me. The issue for me is in piece A28, which is sub part h. The thin wood seems to warp in a way that marbles get stuck in that section, which is unfortunate. I did make errors in other places, and corrected them. But I have triple and quadruple checked, and I built that section properly, and everything is seated fully. It seems this is an error, either in materials or design - the first corner bends up in a way that prevents marbles from going the distance.Still it was a fun and challenging build. I guess it's the journey, not the destination?

The box looked like it had been opened, but all parts were there and my husband put every intricate piece together....in only about 20 hours.It says it take about 7 hours, so not sure why it took so long for my husband, but it works. Our grandchildren love to watch, which is all he'll let them do. lol

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
