Corner protocol on Level 306. Full solution.
Step-by-step walkthrough
Level 306 tests corner protocol. Keep 4 corners empty until drop 15. When corners must fill, matching shapes only. Corner order: BL → BR → TL → TR. Corners that clog take 5+ drops to recover. Level 306 has 9-10 corner-filling moments — prepare for each. Watch the video for corner timing at drops 4, 10, 16, 22, 28.
