GraviTrax Junior offers children aged 3 and up a child-friendly introduction to the diverse world of 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. Building and play fun are combined in this experience. GraviTrax Junior can be expanded indefinitely with additional components or special elements. Sets with themed decorations enable children to design their own worlds for 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 and 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 firsthand. Playing with figures and decorating themed worlds encourages creative role play and children's imagination. With various expansions, the marble runs can be enlarged and redesigned repeatedly, ensuring long-lasting play fun.
