Sand Blocks Level 138 Walkthrough

Overview
Priority row clearing on Level 138. Full solution.
Step-by-step walkthrough
Level 138 requires priority row clearing. Rule: always clear the row with the FEWEST gaps, regardless of position. This keeps the board maximally flat. If row 3 has 1 gap and row 1 has 3 gaps, clear row 3 first. Level 138 becomes winnable in 20 drops with priority clearing, 35+ drops without it. Priority logic: fewest gaps = highest priority.
💡 Pro tip
Clear row with fewest gaps first. Priority = fewest gaps.
