GraviTrax Junior offers children aged 3 and up a child-friendly introduction to the world of themed marble runs. It is an interactive marble run system that allows boys and girls to create their own marble run worlds, which can be flexibly decorated to create unique themed environments. Building and playing fun are combined in this system. GraviTrax Junior can be expanded indefinitely with additional components or special elements. Sets with theme-specific decorations enable children to create their own worlds, ensuring lasting play enjoyment.

With GraviTrax Junior, children build not just simple marble runs. By individually decorating with lovingly designed elements, they create their own themed worlds. Age-appropriate learning content is addressed, and motor skills as well as spatial thinking are enhanced through the free design of the marble runs. Exploring the rolling behavior of the marbles allows children to experience the principle of cause and effect up close. Playing with the figures and decorating the themed worlds encourages creative role play and the imagination of children. With various expansions, children can enlarge and continually redesign their marble runs – long-lasting play fun is guaranteed.
