Sand Blocks Level 15 Walkthrough
10/21/2026
Overview
Level 15 requires vertical space reservation. Full video solution.
Step-by-step walkthrough
Level 15 introduces longer vertical blocks. Before the tall block arrives, create a 1x4 vertical column with no obstacles. Use the preview queue to know when. While preparing, avoid stacking more than 2 rows high. If the tall block lands correctly, it clears a huge vertical chunk of your board for free. If it does not fit, hammer the block below it — never leave it in the tray.
💡 Pro tip
Reserve a clean vertical column for tall blocks. Prepare early.
