Sand Blocks Level 203 Walkthrough

Overview
Cascade chains win Level 203. Full solution video.
Step-by-step walkthrough
Level 203 requires 4+ cascade chains. Set up cross patterns of 4 same-color blocks, drop 5th matching block → 5-way cascade = 5 cells reclaimed. Do this 6+ times per level. Cascade discipline is essential in the 200+ tier — there's no fallback strategy. Level 203 becomes trivial with 6 cascades, unwinnable without any.
💡 Pro tip
4-block cross + 5th = 5-way cascade. 6+ cascades per level.
