LEGO Builder

Kids follow LEGO building steps as 3D models they can spin and zoom, sometimes sharing one set with family.

LEGO Builder is the LEGO Group’s own app for building instructions, and it swaps flat booklet pages for 3D models. Each step can be turned and enlarged, which looks especially handy when a tiny piece hides behind a bigger one. Tapping a single brick lets kids rotate it to see its shape and color before digging through the pile. A Build Together mode appears designed for siblings or a parent and child: everyone joins with a PIN and takes turns on the steps. Pointing the camera at the QR code on a paper manual pulls up matching instructions, and the library reaches back to sets from 2000, so older bricks from the cupboard might find a new purpose. Some themes slip small story moments between steps. It seems to suit any age that can follow a picture, from first builders to grown-ups.
