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

Fun for the whole family! Brought back some nostalgia for my husband. Put this on the fridge door and the kids love playing with it. I have a small cup with the marble held by a chip clip so we don't lose it. The magnets are pretty strong. It stays stable in the high traffic area. Easy to use. My kids are 6 and 8 and my husband is 40, we all enjoy it. It's cool and teaches us about little changes and movement. Really fun.

This marble run provides hours of fun and is easy to assemble on the fridge or any magnetic surface. The materials are high quality, and the magnets hold firmly in place during use. My 7- and 12-year-olds loved creating different marble tracks, which encouraged problem-solving and creativity. The set includes a variety of pieces for endless design possibilities. I recommend purchasing the larger set for even more building options.

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!

My grandson loved this. It’s summer now and he still has it up and creates all kinds of runs. Keeps him thinking and his fingers on something other than electronics.

My family loved putting this together and making their it their own. The magnets are good but sometimes the pieces fall off when the marble is doing its run. I’d say splurge and get the one with the most pieces. We felt like the run was too short once we used all the pieces.

This is a wonderful concept. The pieces however are a little hard to assemble for an adult let alone an 8-year-old.Also about every other ball doesn't make it through the maze without falling.

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!
