Watch the sand pour. Every single grain moves for real — it falls, it piles, it slides. Drop one block and thousands of colored grains stream in, the picture above breaks apart, and the colors settle somewhere you never planned for. Sand Fill is the oddly satisfying block puzzle where physics does the talking. HOW TO PLAY • Look at the sand picture above — colors, shapes, layers. • Drag a block onto the grid below. • The block drinks up every grain that matches its color. • The rest of the sand collapses and resettles. Read it again. • Empty the whole picture before time runs out. One finger. No tutorial needed. You'll get it in ten seconds. IT'S THE PHYSICS THAT GETS YOU This isn't sand-shaped decoration. Grains fall, stack, avalanche and mix. Clear the red underneath and everything above comes down. Every stage is a little collapse you set off yourself. SPACE IS THE REAL PUZZLE The grid below is small, and blocks come in awkward shapes. Park one badly and you've stolen the room you needed three moves later. Strong players don't place fast — they place last. COLORS DON'T STAY PUT Sand mixes as it falls. That clean band of blue turns speckled halfway down, and now you have to dig for it. Bring your blocks to the sand instead of waiting for the sand to come to you. PUZZLES THAT KEEP CHANGING • Hidden blocks that won't show their color until you clear others • Frozen blocks locked behind ice • Layered blocks hiding a second color underneath • Sliding blocks that travel on one axis only • Locks and keys • A brand-new picture every single stage WHEN YOU'RE STUCK • Freeze — stop the clock and think it through • Hammer — smash one block into single squares and spread them out • Magnet — pull every matching grain straight into one block Save them. You'll want them later. FEATURES • Real falling-sand physics, grain by grain • Simple one-finger drag controls • Colorful pictures to uncover • Shape and space planning that actually matters • Clear goals, quick stages, easy to pick up • No wrong way to start — just drop a block Drop the block. Watch it pour. Clear every grain. Download Sand Fill: Block Puzzle and see how far you can go.
