Sand Blocks Level 172 Walkthrough

Overview
L-shape economy on Level 172. Full solution.
Step-by-step walkthrough
Level 172 rewards L-shape economy. Rule: L-shapes only for double-gap fills (tail in gap 1, long-arm in gap 2). Random L-shapes waste 2 cells each. Cluster 3 L-shapes of same color, drop a 4th to trigger 4-way cascade (16 cells reclaimed). Level 172 becomes trivial with L-shape discipline, painful without it. Watch the video for L-shape economy in action.
💡 Pro tip
L-shapes only for double-gap. Cluster 3 for cascade.
