Sand Blocks Level 39 Walkthrough
10/21/2026
Overview
Small blocks are your rescue tool on Level 39. Full guide.
Step-by-step walkthrough
Level 39 mixes large and small blocks aggressively. Small blocks (1x1, 2x1) are your rescue tool — save at least 1 small block in reserve at all times. When a 1-cell gap appears, drop that small block immediately. Never use small blocks for large fills — they're too valuable for tight gaps.
💡 Pro tip
Reserve small blocks for tight gaps. Never waste them on large fills.
