GraviTrax Junior allows children aged 3 and up to enter the world of marble runs in a child-friendly way. It is an interactive marble run system that enables 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 experience. GraviTrax Junior can be expanded indefinitely with additional components or special elements. Sets with theme-specific decorations allow children to design their own worlds, ensuring lasting play enjoyment.

With GraviTrax Junior, children not only build 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 promoted 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 (animal) figures and decorating the themed worlds encourages creative role play and the imagination of children. With various expansions, the marble runs can be enlarged and redesigned repeatedly, guaranteeing long-lasting play fun.
