The LEGO Builder app takes children on an intuitive building adventure. Within the app, they can zoom in and rotate 3D views of the models, save sets, and track their building progress. This building and play set makes a great birthday or Christmas gift, allowing younger children who love adventure and dinosaurs to immerse themselves in the Jurassic World universe. For even more fun, these figures and models can be combined with other separately sold LEGO Jurassic World sets. The set contains 199 pieces.
