The Powder Toy

The Powder Toy: Where Science Meets Imagination (and Explosions)

The Powder Toy is not your average sandbox game—it’s a dazzling playground for science lovers, tinkerers, and chaos enthusiasts alike. If you've ever wanted to blow things up, build a functioning nuclear reactor, or program a digital computer from scratch using particles, this free simulation game is calling your name.

What Is The Powder Toy?

At its core, The Powder Toy is a 2D physics sandbox that simulates the behavior of over 200 different materials and particles. You can combine, combust, or cool these elements to explore real-world physics concepts like thermodynamics, gravity, pressure, and electricity—all within an addictively simple pixelated world.

But it doesn’t stop at realism. The Powder Toy invites you to push boundaries with sci-fi materials and fantastical elements. From antimatter to force fields, you can create a world that mirrors reality—or rewrites it.

What Can You Do in The Powder Toy?

Master Explosives and Detonations

Craft TNT-packed contraptions, simulate nuclear blasts, and unleash your inner demolitionist. It's like having a virtual chemistry set with fewer safety rules and more dramatic results.

Design Functional Power Plants

Engineer your own nuclear, chemical, or hydroelectric reactors, simulating everything from heat transfer to electrical output. Perfect for aspiring engineers and energy nerds.

Build Custom CPUs and Logic Circuits

Yes, you can build a fully functional computer inside this sandbox—complete with memory, logic gates, and more. It's a dream come true for fans of digital logic and electronics.

Let Your Imagination Go Wild

Whether you're designing post-apocalyptic bunkers, beautiful animated art, or incredibly precise machines, The Powder Toy has the tools to make it real.
