Trestle Tracks Builder Set

Trestle Tracks is a truly mesmerizing marble-track experience, made up of hollow stacking cubes and a variety of perfectly flat tracks. The paths cut out of each track widen almost imperceptibly from one end to the other, creating an invisible slope that propels the marbles forward - watching them go is like magic in slow motion! Encourages spatial reasoning, creativity, engineering skills, problem-solving and critical thinking. The builder set includes a base grid for added stability, and comes with guided build designs. Plus, you can get creative and invent your own designs. Comes with 1 catcher, 1 topper, 55 risers, 5 stainless steel marbles, 10 unique tracks and base grid. Sets are compatible, so you can build even larger runs. For ages 8 and up.
