LEGO® Builder: 3D Instructions

LEGO® Builder: 3D Instructions is the official app for exploring and building LEGO sets with immersive 3D guidance. Whether you're constructing your first set or completing a lifelong collection, this app transforms brick-by-brick assembly into an engaging digital experience.

Navigate every build with clarity and control. The 3D viewing system lets you zoom, rotate, and examine sets from every angle, making it easy to spot the right pieces and understand how they connect. Step-by-step digital instructions display each brick clearly, so you can build with confidence and accuracy. The intuitive interface works for builders of all ages and skill levels.

Build Together brings the joy of collaborative creation to life. Invite friends and family to join your building session by sharing a PIN code—one person hosts while others join as builders. You can divide tasks, take turns completing steps, and work toward finishing the model as a group. This mode transforms individual building into a social activity, making it a natural fit for family nights, celebrations, holidays, and special occasions. Check the app to see which of your sets support this multiplayer feature.

Access a vast digital library of instructions spanning two decades of LEGO history. Search by set name or number, or use your phone's camera to scan the QR code on your instruction manual—the app opens it instantly. Unlock enriched content and guided narratives for select LEGO themes, adding storytelling depth to your building journey.

Save your progress and track your achievement with a LEGO Account. Build a digital collection of your sets, record completed models, and watch your total brick count grow. Pick up any project later, on any device, without losing your place—your progress syncs across sessions.

Keep a record of every set you've finished and celebrate your building milestones. The progress tracker shows your total bricks built and completed sets, turning your building habit into a visible accomplishment.

A stable internet connection is required to use the app. New digital instructions are added regularly, so your collection can grow as LEGO releases new sets.
