Overview
Sticky corner protocol on Level 429. Full solution.
Step-by-step walkthrough
Level 429 sends 10-11 sticky blocks per level. Sticky blocks in corners ONLY. If all 4 corners full, hammer one immediately. Never drop sticky in open board — permanent cell loss. Level 429 has more sticky blocks than most levels — corner protocol is your entire strategy. Watch corner opening timing at drops 4, 12, 20, 28.
💡 Pro tip
10-11 sticky blocks. Corners only. Hammer to open corner. Non-negotiable.
