Build ideas from the pieces you own

Build ideas compares the pieces in the sets you own with other sets, and lists the ones you already have most of the pieces for. It is a list of ideas. It does not show building instructions.

How to use it

  1. Open My sets.
  2. At the bottom, tap Build ideas.
  3. Tap Check my pieces.
  4. Wait while the app compares your pieces. It can take a minute.

Reading the results

Each result shows a set’s picture and name, how many of its pieces you have, and a percentage. The closest matches come first. A line above the list says how many sets your pieces were compared with.

Tap Check again to run it again, for example after adding more sets.

How it decides

  • It counts every piece in every set on your list, spare pieces included, whether or not you have sorted them yet. Pieces you marked as missing are left out.
  • It compares them with sets released from 2015 onwards that have at least 50 pieces. Sets you already own are left out.
  • A piece only matches the same piece in the same colour. Owning one of a piece does not cover a set that needs six.
  • A set is listed if you have at least 60% of its pieces. Up to 100 sets are listed.

What the messages mean

  • If the app says there are no strong matches yet, nothing reached 60%. Adding more sets gives it more to work with.
  • If it says some of your sets are not in the parts catalogue yet, the pieces of those sets could not be counted.
  • If it says it ran out of time, the check stopped early and the list shows what turned up so far. Tap Check again.

Limits worth knowing

  • Having 60% of a set’s pieces is not the same as being able to build it. Treat the list as a starting point.
  • It needs an internet connection.
  • The results are not saved. Run the check again when you want a fresh list.
  • The list is for reading. You cannot add a set to your own sets from it. To add one, use Adding your sets.
