GraviTrax Junior is an interactive marble run system for boys and girls aged 3 and over: With GraviTrax Junior, children don't just build simple marble runs. Children can create their own themed worlds by decorating them individually with lovingly designed elements. GraviTrax Junior focuses on age-appropriate learning content. Motor skills and spatial thinking are encouraged through the free design of the marble runs. By exploring the rolling behaviour of the balls, the principle of cause and effect is experienced at first hand. Playing with the (animal) figures and decorating the themed worlds encourages children's creative role play and imagination. Various extensions allow children to extend their marble runs and design them again and again - for long-lasting playtime fun.
