Sorting & Inventory

What can I build with the LEGO® bricks I already own?

The short answer

Brick Finder compares the bricks in your collection with 21,800+ official LEGO® sets and ranks every set by the share of its pieces you already own. At the top you see the sets you can build right now; just below are sets that are only a few pieces away. Pick any set to see exactly which pieces are missing, pictured and counted.

How it works

  1. Build your collection: scan trays of loose bricks with BrickVision™, and add the sets you own by typing a set number.
  2. Open What can I build? Brick Finder checks your pieces against every set in the catalogue.
  3. Browse the ranked list: sets you can build now, then sets you can almost build.
  4. Pick a set to see the missing pieces, and for 1,800+ sets watch it build in 3D.

What is in a bin?

If you scan a bin of mixed bricks, the top matches show which sets the pieces most likely came from. In our demo, a scanned bin's top matches were LEGO® Classic sets 10717 and 11717.

Good to know

  • The catalogue of 21,800+ official LEGO® sets is built into the app, so this works offline.
  • Counts are as good as your inventory: check your scans and correct pieces before relying on a match.
  • Ordering missing pieces from LEGO® Pick a Brick or BrickLink needs an internet connection.
