Pixel Reactor

About Pixel Reactor: Falling-Sand Chemistry Simulation

Pixel Reactor is a falling-sand chemistry simulation where every pixel is individually simulated and every reaction is drawn from real chemistry. Drop sodium into water, burn metals in chlorine, test flame colours on a wire loop, or split water with a battery — 217 reactions are waiting to be discovered across 24 chapters. Each experiment is filmed for your own science channel, where bigger and brighter reactions earn more views. Subscribers unlock crates containing new elements, and the chemicals produced in one experiment can be bottled and carried into the next. Part sandbox, part puzzle, every page added to your Collection Book shows the real equation behind what just happened.

How to Play Pixel Reactor: Discover Reactions Across 24 Chapters

Load your tray with elements and chemicals from the shelf, pick a tool, and watch what happens. The pill above the tray tells you what to try next or presents a riddle to solve. Every new reaction is recorded in your Collection Book and posted as a video — views bring subscribers, and subscribers unlock crates with new elements.

Collection Book and Progression

• Each discovered reaction is added to the Collection Book, which displays the real equation behind it.
• Reactions posted as videos earn views, views bring subscribers, and subscribers unlock crates with new elements.
• Chemicals produced during experiments can be bottled for use in future experiments.
