Sand Blocks Level 153 Walkthrough

Level 153 has variable sand flow — some sections flow left, some right. Read the flow before dropping: test 1 small block per section first (drops 1-3). Once calibrated, use flow direction to your advantage — drop blocks so spill fills 2 cells naturally. Unread flow = wasted drops. Read flow = 3 cells per drop. The 3 test drops at the start save 10 moves later.
