Sand Blocks: Clear the Lines

About the game

Sand Blocks: Clear the Lines is a fresh take on the classic Tetris formula with realistic sand physics. When tetrominoes land, they crumble into hundreds of sand particles that behave like real sand, filling the level in dynamic and unpredictable ways. Instead of simply clearing rows, you must think about the flow of sand and how piles form and collapse.

The game features two main modes: Endless Mode and Campaign Mode, which includes hundreds of levels with objectives and up to three stars to earn for completing challenges.

Key features include dynamic sand physics, unique power-ups (bomb — destroys a large area; vacuum — removes accumulated sand; slow motion — gives you extra time to place pieces precisely), in-game currency, a booster shop, and a progression system.

How to play

Pieces drop from the top just like in Tetris, but the moment one lands it crumbles into hundreds of grains of sand. The sand slides downhill, fills gaps and spills over the edges, so a line is built from a loose pile rather than neat bricks. Your job is to complete rows and clear the field while keeping the pile under control.

Campaign levels each come with their own objective and up to three stars for meeting it. Endless Mode has no finish line: you keep going as long as you can.

Tip: drop pieces where the sand will run into a dip instead of stacking on a peak, and the surface stays flatter. Save the bomb and the vacuum for when the pile gets dangerous, and use slow motion right before a placement that needs precision.

Controls

Move and rotate the falling piece before it touches the sand.
Desktop: with the mouse.
Phone: with taps, in either portrait or landscape.

FAQ

How is Sand Blocks different from regular Tetris?

A landed piece doesn't stay solid: it turns into sand that spreads across the field. You have to think about where the pile will slide, not just the shape of the row.

How do I get three stars on a level?

Stars are awarded for meeting a Campaign level's objectives. If you missed one, replay the level and aim for cleaner placements.

What do the bomb, vacuum and slow motion do?

The bomb wipes out a large area, the vacuum sucks up built-up sand, and slow motion buys you extra time to place a piece precisely.

Will I lose my Campaign progress if I close the tab?
