About Sand Blocks: Clear the Lines

You drop tetromino blocks that crumble into flowing sand particles on impact in Sand Blocks: Clear the Lines. Each piece breaks apart and settles according to realistic physics, so you have to predict how the grains will pile up and shift. Your job is to fill horizontal lines completely with sand to clear them and earn points, but the sand behaves unpredictably—it tumbles, slides and forms peaks wherever it lands.

The game offers an endless mode for continuous play and a campaign with hundreds of puzzle levels that set specific goals and award up to three stars for performance. Power-ups like bombs and vacuums let you blast away large sections or suck up excess sand when things get messy. Available on Poki Games, this version of the block-stacking genre demands both spatial planning and an understanding of how loose particles behave under gravity.
