Drizzl vs Grainfall

Pour. Mix. Destroy. Repeat. Drizzl isn't just a sandbox. It's a living physics engine. Drizzl is a falling sand simulator that tracks thousands of particles as they flow, pile, and interact in surprising ways. Pour Sand, swirl Fluid, stretch Slime and Goop, drift Gas, build with Wall, then drop in a Solid or hang a Rope and watch everything respond. ENDLESS POSSIBILITIES - Mix Materials: What happens when heavy sand hits light gas? Or when a rope swings through slime? - Create Art and destroy it (if you please). Choose colors and brush size for each experiment. - Discover Interactions: Every combination behaves differently. Experiment with gravity, mixing, and flow to find your own satisfying loops. - Live Sound: The sound isn't a loop. It follows the physics and knows the difference between a soft slide and a heavy crash. Mix materials and you mix the soundscape, an ASMR soundtrack that is yours alone. - Little Ideas: Follow an optional creative idea when you want direction. There is no score and no required finish. THE EXPERIENCE - Pour & Slice: Create satisfying mounds, then slice or scoop clean lines through them. - Tilt & Chaos: Tilt to slide the pile, or shake your device to send everything flying. - Rewind: Return to a moment worth keeping. Pause, open the Hatch to let it drain, or clear the canvas for a new start. - Zone Out: A quiet break, or just satisfying that fidget itch. THE DETAILS - Sand, Gas, and Wall are free to explore. Fluid, Slime, Goop, Solid, and Rope are included with Unlock All. Try them with one free session or an optional rewarded ad when available, then purchase Unlock All for permanent access and no interruptive ads. - Haptics follow the motion on supported devices. - No accounts. No login. Core play works without an account; ads and store actions may need a connection. Existing Fluid Pack purchases carry over as Unlock All under the same Apple Account. Use Restore Purchases if the entitlement does not appear. Previous native canvases do not transfer to this new canvas format.

Grainfall is a falling sand toy. Pick a material, drag across the screen, and watch it react with whatever is already there. Sand piles up and slides back down. Dig a hole and water will find it. Oil floats on top of water, and oil burns. Plants drink from standing water and creep toward it. Fire spreads, leaves ash behind, and boils water into steam that drifts up, cools off, and comes back down as rain. There is no score and nothing to unlock by playing. What you get is twelve materials that all react to each other, and the fun is working out how. Build a glass tank and fill it with acid, since glass is the one thing acid cannot chew through. Pour lava into water and it sets into stone. Light one end of a gunpowder trail and follow it along. Hit record at any point and Grainfall turns what happened into a video, with sound built from the same events you just watched. Save a world and it keeps a picture of itself in your list. Send one to a friend as a small file and it opens straight into their copy.
