Atomcraft
Mine, smelt and automate your way across a simulated world, chasing every element to fix your ship.
Hooked on the chaotic and relaxing side of Pixel Rain? These games offer a similar pull for your backlog.
A falling-sand sandbox with over 500 elements and thousands of reactions between them. Pour water on hot metal, grow a tiny ecosystem, cook a pixel pizza, or just watch fire spread. No goals, no failure, no timer: a toy box of chemistry and physics you can poke at for five minutes or five hours.
Chaotic, Relaxing, Colorful
A relaxing falling-sand sandbox with pixel particles, digital circuits and playable stickmen. Build contraptions, automate things, or just flood a tunnel with sand and watch it pour. It runs at your pace, and there is always one more element to try.
Chaotic, Relaxing, Colorful
A pixel-physics sandbox. Fifty materials, and every one of them is physics: sand finds its angle, water freezes, lava crusts into stone, gunpowder blows. Build your own materials and worlds, and share them in the Workshop.
Chaotic, Relaxing, Colorful
Build a nuclear reactor, wire a working computer, or just drop a bomb on your own city and watch the fallout drift. Runs on nearly anything, and one more experiment is always five minutes away.
Chaotic, Relaxing, Replayable
Graviton is a falling sand simulator in which you define your own interactive sand art. Sit back, relax, and draw from existing sand materials. Or take time to learn and create your own sands with complex rules. The possibilities are endless!
Chaotic, Relaxing, Colorful
This water physics sandbox lets you experiment with realistic fluid behavior, sink ships by using bomb explosions, and enjoy a ragdoll people playground built to simulate destruction.
Chaotic, Relaxing, Colorful
Every pixel in Atomcraft is simulated, so the world is less a map and more one enormous chemistry set. Dig through a procedurally generated planet, smelt ore, wire up machines from conveyor belts to logic gates, and chase all 118 elements to repair your crashed ship. Bring a curious mind: the chemistry is real enough to send you down rabbit holes.
Chaotic, Relaxing, Colorful
Mix elements like a mad scientist on a particularly spicy date with destiny! Embark on a journey through the mystical caves of Dormacom with our hero Vurhne as he seeks out the ultimate power for no good reason at all!
