The 585-piece construction set includes six different extensions and is the largest set in the history of Hubelino. In addition to numerous building blocks, run elements, base plates, marbles and special components, the large construction set also includes a comprehensive instruction book with three gigantic assembly ideas incl. an exciting race track.

The largest marble run construction set from Hubelino contains all components for the construction of giant marble runs including the six expansions twister, catapult, cradle chute, see-saw, switch and marble lift. Due to the large number of different building blocks and run elements, it is possible to build both simple and challenging marble runs, race tracks and courses, which makes the mega building box an ideal building set for beginners. A detailed illustrated instruction book with three different assembly variants makes it easier to get started with building and inspires the little master builders to come up with their own assembly ideas.

Our modular and compatible marble runs are designed to stay put, so your kids can focus on the fun. They promote spatial intelligence and an understanding of fundamental physical concepts like acceleration and gravity. Wether with an instruction booklet or with free play, constructing a marble run stimulates working memory, and improves the capacity for analytical thought. And best of all, we’re building on an existing system to extend its life in the childrens room.
