GraviTrax Junior offers children aged 3 and up a child-friendly introduction to the diverse worlds of marble runs. It is an interactive marble run system that allows boys and girls to create their own marble run worlds. These can be flexibly decorated, resulting in 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 enable 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 enhanced through the free design of the marble runs. Exploring the rolling behavior of the marbles allows for a hands-on experience of the principle of cause and effect. Playing with figures and decorating themed worlds fosters creative role play and the imagination of children. With various expansions, the marble runs can be enlarged and redesigned repeatedly, guaranteeing long-lasting fun.
