Expand the cavity, trigger the collapse. A sand-physics puzzle game.

<h2 class="bb_tag" >&quot;Crush sand. Crush time.&quot; ThouSandSand </h2>A sand-physics puzzle game with 1,000 grains and zero deadlines. Match, collapse, and kill time — one satisfying avalanche at a time.<h2 class="bb_tag" >About This Game</h2>You've got a thousand grains of sand and nowhere to be.ThouSandSand is a falling-sand puzzle game inspired by the classic SameGame formula. Tap matching clusters to clear them — but instead of rigid blocks, every grain tumbles, slides, and piles up with satisfying sand physics. Watch the board reshape itself with every move.The Cavity — When you clear a cluster, the space doesn't collapse right away. A hollow cavity lingers in the sand. Clear another cluster before it caves in, and the cavities merge — growing bigger, more unstable, more spectacular. Push your luck and chain clears together for a massive cascading avalanche… or play it safe and let gravity do its thing.It's the tension between thinking and acting. Plan your moves carefully with no time limit — but once you start a chain, the clock is ticking. How greedy can you afford to be?The sand settles. You start again. There's always one more move to find.<h2 class="bb_tag" >Features</h2><ul class="bb_ul"><li>1,000 Grains — Every grain is simulated. No grid tricks, no fake physics — just sand being sand.</li><li>Cavity Chain System — Hold off the collapse. Stack your clears. Trigger avalanches that reshape the entire board.</li><li>Think, Then Act — No timer while you plan. The pressure only starts when you make your first clear.</li><li>Endless Mode — No finish line. Just you, the sand, and the high score.</li><li>One More Turn — The kind of game where &quot;five minutes&quot; becomes an hour. Perfect for winding down, zoning out, or procrastinating with purpose.</li></ul>
