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 form unique themed environments. Building and playing fun are combined in this system. GraviTrax Junior can be expanded indefinitely with additional building components or special elements. Sets with themed decorations allow 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 firsthand. Playing with figures and decorating 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 fun.
