This Trestle Tracks Builder Set Marble Run includes a variety of interlocking track pieces, supports, marbles and connectors that children can arrange in countless configurations. The modular design makes it easy to start with simple builds and expand into more complex tunnels, drops and curves.

Assembly involves aligning track segments, clicking supports into position and carefully placing marbles at the start — creating a dynamic play experience where children predict, test and revise their designs. By connecting the physical action of building with the visual feedback of motion, this marble run bridges creative play with fundamental problem-solving.

Ideal for independent exploration, collaborative play with friends or family, and classroom or therapy settings, the Trestle Tracks Builder Set provides hours of “build-and-watch” fun.
