GraviTrax Junior is an interactive marble run system for boys and girls aged 3 and up: with GraviTrax Junior, children do more than just build simple marble runs. By decorating with charmingly designed elements, they create their own themed worlds. GraviTrax Junior incorporates age-appropriate educational concepts. Motor skills and spatial reasoning are fostered through the free-form design of the marble runs. Exploring how the marbles roll allows children to experience the principle of cause and effect firsthand. Playing with the (animal) figures and decorating the themed worlds encourages creative role-play and imagination. Various expansion sets allow children to enlarge their marble runs and redesign them again and again—guaranteeing long-lasting playtime fun.
