How these source sets were selected

NINJAGO catalog sets from 2011 onward, with standard five-digit set numbers ending in -1 and between one quarter and twice this set's catalog piece count (at least 50 pieces). Ranked by the number of exact shared pieces; ties favour higher source inventory coverage. This is a limited catalog comparison, not a claim about price, availability or the best set to buy.

Totals use inventory quantities, which can differ from the advertised box count. Snapshot: 2026-09-21. Original catalog colours are preserved. The source inventory contains 1,741 non-spare pieces; 14.8% are usable for this target. Inventory corrections after this date are not included.
