Sand & Sky vs Falling Matter

Sand & Sky is an endlessly satisfying particle physics sandbox — drop materials, watch them interact, and discover what happens when science meets creativity. Pour water and watch it fill every corner. Drop lava onto ice and forge obsidian. Ignite gunpowder and set off chain explosions. Build walls, draw mazes, and experiment unique materials that each behave according to their own rules. REACTIONS & COMBINATIONS Every material interacts with others in surprising ways. Water meets lava and creates stone. Lightning strikes sand and fuses it into glass. Acid dissolves almost everything. Discover all the reactions in the built-in Reactions guide. FEATURES · Realistic fluid simulation — liquids fill containers and accumulate naturally · Flip gravity in any direction — up, down, left, or right · Wind tool to push particles across the screen · Adjustable brush size and simulation speed · Undo button and sandbox clear · Unique sounds for every material Whether you're building elaborate contraptions, running experiments, or simply watching particles fall — Sand & Sky is the perfect zen sandbox to lose yourself in.

Falling Matter is a pixel physics sandbox where every grain matters. Pour sand, flood it with water, drop lava on top and watch the world react. REAL PHYSICS, REAL HEAT • Every pixel has a temperature. Heat spreads fast through metal and slowly through wood and air. • Water boils and freezes, ice melts, lava cools into obsidian, sand melts into glass. • Liquids settle into layers by weight: gasoline floats on oil, oil on water, mercury sinks below everything. • Turn on Heat view to see your world through a thermal camera. 60+ MATERIALS AND TOOLS Powders, liquids, gases, metals, explosives, plants and people. Mix acid with metal to make hydrogen, cool red-hot metal in water, burn wood into glowing charcoal, or let thermite burn through a steel plate. BIG BOOMS Drop an atomic bomb on a city, call down a meteor, strike with lightning, or open a black hole and watch it swallow everything nearby. Explosives, black holes, meteors, lightning and people are part of the Unlock All Matter upgrade. BUILD, SAVE, SHARE • Start from six ready-made worlds or a blank sandbox. • Four save slots with previews. • Share a picture or an 8-second video clip of your creation. • Pinch to zoom in on the smallest grains. AND MORE • Tilt your phone to pour, like sand in a jar. • 13 trophies, with Game Center achievements. • Sound effects and vibration for explosions and lightning. • Tips that explain each material (turn them off any time). • In English, Spanish, Portuguese, French, German, Japanese, Korean and Chinese. • Free to play.
