NATIONAL GEOGRAPHIC Magnetic Marble Run - 75-Piece STEM Building Set for Kids & Adults with Magnetic Track & Trick Pieces & Marbles for Building A Marble Maze, STEM Project (Amazon Exclusive)

This toy set is great! My nephews loved playing with it and setting it up on their fridge. Lots of tiny parts though, so beware of losing any marbles or tracks if you have smaller kids or pets!

awesome product

I purchased this magnetic marble run set for my 8-year-old and it's been a big hit! The 75 pieces offer a good variety of tracks, trick pieces, and marbles, making it easy to create a wide range of marble maze designs. The magnetic tiles stick well to a magnetic board or the fridge, and the clear plastic track pieces let you see the marbles race through—which adds a fun visual element.What we loved:STEM Learning in Action: My kid quickly got into problem-solving mode, figuring out how to get the marbles from top to bottom without falling off or getting stuck. Great for encouraging creativity and engineering thinking.Strong Magnets: The magnets are surprisingly strong. Once you lock the pieces in place, they stay put, which is especially important for tall builds.Colorful and Engaging: The bright colors and the variety of track shapes kept things interesting, and it was fun for both kids and adults to join in.A few tips:Use on a Magnetic Surface: This set doesn't include a magnetic board, so make sure you have a surface like a whiteboard, fridge, or magnetic easel ready.Plan Your Build: Start with a basic design and gradually add complexity. Gravity is key here—make sure each track has a proper downward angle or the marble will stall.Combine Sets: If your kid really enjoys this, consider buying an expansion set. 75 pieces are enough for fun builds, but a larger set offers more creative options and stability for bigger designs.Why 4 stars and not 5:Limited Stability: While the magnets are strong, the plastic tracks can pop out if you bump the structure or if the design is too ambitious without proper support.No Base Included: A magnetic board or base plate would’ve been a helpful addition for easier setup and play.Overall, this is a solid and educational toy that sparks curiosity and creativity. A great gift for STEM-minded kids, especially if you already have a magnetic play surface at home.

I purchased this for my nephews, and it has been a massive hit! From the moment they opened the box, they were completely captivated by the endless possibilities for building and creating.The magnets are strong and sturdy, making it easy for little hands to assemble and disassemble the pieces without frustration. I love how this set encourages creativity and problem-solving while also teaching basic STEM concepts in such a fun and engaging way. My nephews have built everything from simple shapes to complex structures, and their excitement never fades!As a bonus, the included guidebook provides great inspiration for new designs, but the kids love to freestyle their own creations too. It’s a perfect blend of fun and education, and I feel great knowing it’s helping them develop important skills like spatial awareness and teamwork.The quality is fantastic—durable, safe, and well-made. It’s also compact enough to store easily, and the storage bag is a thoughtful addition for keeping everything organized.I would highly recommend this to any parent, teacher, or caregiver looking for a creative, hands-on activity for kids. Whether for playtime, homeschooling, or just some screen-free entertainment, this set is worth every penny!

Excellent for fridge or dishwasher. Very nice set. Uses standard sized marbles!

Of all the gifts my 7 year old grandson received for Christmas, this was the biggest hit! There is just so much fun and opportunity for creativity with this marble run building set! The design options are literally infinite and the process is both fun and it does take some time to get the design to function like you want.As you can see from the attached picture, we put up two metal white boards on the wall behind a door to one of our guest rooms. The paper template you see at the top was just to help him model his first design to get a feel for things. So it's cool that he can begin to work on a design and even if he isn't able to complete it, it's perfectly in place for when he comes back the next time. And it's out of sight and out of mind until he returns! I ended up purchasing two of these, one for his use at his home and one for use and my home. I guess we'll see, but I expect this will be a "game" he'll not lose interest in for several years! I highly recommend!

Fantastic idea, but needs to go back to drawing board for some strengthening tips so you get your $$ worth.Very very fun activity. I have it on the side of the fridge and every child that comes in has to inspect and play with it.I've created a number of configurations with all 6 of my grand children now. Each one having a blast. The poor reviews pretty much nailed all the issues I also had with the set.. but it's certainly worth more than a 1 rating. I wouldn't go above a 3 due to the expense of it vs the quality.Value? well it's not really for little fingers and frankly the pieces break, twist, or come apart very easy. They don't really snap in as nicely as you would hope so that adds to the difficulty of getting a working structure. Plus the magnet wasn't really strong enough to keep the pieces in place after 1 or 2 marble runs.Our set was missing pieces, one piece missing was vital to the battery operated Shute. We worked around that missing piece. but that was a bummer.I would have to say we got a ton of fun but 70 dollars is a lot to pay for something that's pretty much ruined after a few months, (and not because of rough play either). It's really fragile so it should be considered for older kids.

My little sister in law loved it, although her parents didn't appreciate my gift, as the fridge was always a mess lol
