Overview
Corner protocol on Level 237. Full solution.
Step-by-step walkthrough
Level 237 tests corner protocol. Rule: keep 4 corners empty until drop 12. When corners must fill, use matching shapes only. Corner order: BL → BR → TL → TR. Corners that clog take 5+ drops to recover. Level 237 has 8-10 corner-filling moments — prepare for each. Watch the video for corner timing at drops 3, 9, 15, 21.
