Sand Blocks Level 38 Walkthrough

Level 38 rewards large-block merges. When two 2x2 blocks of the same color touch, they merge into a 4x4 — freeing a huge area. Cluster the initial 2x2 blocks near each other. Drop matching 2x2 blocks in adjacent positions 2-3 moves in a row. The merged 4x4 becomes a super block that clears a full row when it merges with more of its color.
