Breaking Sand

Break the blocks and let the sand pour!

Bounce balls into blocks and fill horizontal rows with the sand that falls. When a completed row clears, the sand above settles into the gaps, setting up the next combo.

Where you break blocks and where the sand lands both matter. Find your angle in a brick-breaking puzzle where every shot can change your strategy.

🎯 Bouncing balls, falling sand, cascading combos

Use the walls to send balls between blocks and find angles that keep them bouncing. When falling sand fills another row after a clear, a chain combo begins. Feel the impact of breaking blocks, then enjoy watching the sand pour, settle, and clear.

🧩 Breaking more is only half the puzzle

If the sand or blocks piled below reach the danger line, it's game over!

Aim to fill gaps and clear rows before one side piles too high. Discover different strategies in stages where sand flows freely and stages where solid blocks stack up.
