Sand Blocks Level 123 Walkthrough
10/21/2026
Overview
Level 123 spams medium blocks. Here is the survival plan.
Step-by-step walkthrough
Level 123 sends medium blocks (2x2) aggressively. Medium blocks fill 4 cells per drop — that's 40 cells used in 10 drops. Rule: merge medium blocks with same-color medium blocks immediately. Medium+medium merge = 8 cells reclaimed in 1 drop. If no same-color medium is available, hammer 1 medium block to make space. Do NOT let 4 medium blocks accumulate without merging.
💡 Pro tip
Medium blocks: merge or hammer. Never accumulate 4+.
