Sand Blocks Level 303 Walkthrough
10/21/2026
Overview
Cascade engine required on Level 303. Full solution.
Step-by-step walkthrough
Level 303 requires a cascade engine — 8+ cascades per drop, consistently. Set up 4 same-color blocks in cross pattern, drop 5th → 5-way cascade (5 cells reclaimed per drop). Do this 10+ times per level. Cascade engine is the entire strategy at this tier — no fallback exists. Level 303 winnable in 22 drops with 10 cascades, unwinnable without.
💡 Pro tip
4-block cross + 5th = 5-way cascade. 10+ cascades per level. Engine mode.
