My 7-year-old is obsessed with this set. He loves figuring out how to make the train go higher and even upside down. The cubes click together firmly, and nothing falls apart while the train runs. It’s the first toy that feels like fun and learning at the same time.

We’ve rebuilt the track at least a dozen different ways—bridges, spirals, tall towers—you name it. The train handles the curves and slopes really well. I like that it’s STEM-focused and keeps my kids off their tablets for a while.

Super easy to set up right out of the box. The instructions give you ideas, but my kids quickly started creating their own designs. The materials feel sturdy, edges are smooth, and the bright colors make it extra appealing. Great gift for any little builder.
