Sand Blocks Level 505 Walkthrough

Level 505 requires three-zone precision: left (cols 1-3), center (cols 4-5), right (cols 6-8). Build and clear each independently. Zero cross-zone drops. Precision = zero slop at zone boundaries. Three-zone splitting gives 3x flexibility but requires strict discipline. Level 505 fails at the seams if you're sloppy — 80% of losses come from cross-zone drops.
