Sand Blocks Level 13 Walkthrough
10/21/2026
Overview
Level 13 fails if the center clogs. Here is how to protect it.
Step-by-step walkthrough
Level 13 tests center management. The center column is the lifeblood of the board — if it fills up, you have no flexibility left. Rule: never drop a block in the center unless it's required for a row clear. Route everything through the sides. If a big block is queued and the center is the only open spot, hammer the bottom center cell first, then drop.
💡 Pro tip
Center column is sacred. Protect it at all costs.
