GraviTrax Junior offers children aged 3 and up a child-friendly introduction to the world of marble runs. It is an interactive marble run system where boys and girls can create their own marble run worlds, which can be flexibly decorated to form individual 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, promoting motor skills and spatial thinking 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 children's imagination. With various expansions, the marble runs can be enlarged and redesigned repeatedly - ensuring long-lasting fun.
