Sand Blocks Level 109 Walkthrough
10/21/2026
Overview
Reserve 2 small blocks on Level 109. Here is why.
Step-by-step walkthrough
Level 109 sends 1-cell and 2-cell gaps regularly. Keep 2 small blocks in reserve at all times — do NOT drop them on large fills. When a 1-cell gap appears (from sand spill or bad merge), that's your small block's moment. Level 109 becomes trivial with reserve discipline, painful without it. Rule: only touch small blocks when the gap is 2 cells or smaller.
💡 Pro tip
Reserve 2 small blocks. Only use for 2-cell or smaller gaps.
