Sand Blocks Level 19 Walkthrough

Level 19 is uniquely dangerous because the queue orders large blocks early. The fix: clear the bottom 3 rows immediately on moves 1-5. This creates a buffer of 3 empty rows that swallows everything that comes next. If you can't clear 3 rows by move 6, use a line-clear booster. Level 19 without a buffer is basically unwinnable.
