Sand Blocks Level 159 Walkthrough

Level 159 requires top row defense. Rule: the top row (row 8) must stay empty at all times. If a block reaches row 8, you have 2 drops before game over. Clear the board aggressively — drop priority switches to row 6-7 filling. Level 159 has 4-5 critical moments where the board hits row 7. Use boosters at each critical moment (1 per 8 drops). Survivability test more than strategy test.
