Sand Blocks Level 167 Walkthrough

Level 167 has a corner vacuum — blocks placed near corners get pulled toward open corner spaces. Exploit it: drop 1 block near an empty corner, and sand flows into the corner automatically. 1 drop = 3 cells filled (drop + 2 corner cells). Keep 1 corner empty at all times for vacuum exploitation. Level 167 becomes 30% faster with corner vacuum strategy.
