A sandbox for the endlessly curious

Small particles.
Big possibilities.

Wire up a wild idea. Mix a little chaos. Build a world, then find out what makes it tick.

More than falling particles

One sandbox.
A thousand rabbit holes.

From your first beaker to your most ambitious machine, follow an idea wherever it takes you.

A whole world of matter

Paint with solids, liquids and gases. Combine materials and see what your experiment becomes.

Browse the material library and pick directly from your world.

Make a reaction happen

Dissolve solids, work with acids and bases, and explore heat-releasing and heat-absorbing processes.

Inspect dissolved contents instead of guessing what is in the liquid.

Build something that works

Place batteries, wire components and build logic. Follow voltage, current and power through your design.

Resize components and reach settings directly from the world.

Go with the flow

Connect pipes, pumps and filters. Build a cooling loop or a pressure vessel and see where the fluid goes.

Shape the apparatus around your experiment.

Turn up the energy

Heat it, cool it, boil it. Explore changing phases, pressure and the aftermath of an explosion.

Switch overlays to look beyond the surface.

Put your ideas in motion

Grab bodies, experiment with gravity and build structures that can move, deform or break.

Go from a static sketch to a moving contraption.

See what is really happening

Pin measurements to regions, compare temperatures and inspect material composition as you build.

Move and resize your observation regions alongside the experiment.

Make the lab your own

Arrange panels, save experiments and reuse creations. Right-click tools for relevant controls.

Spend less time in menus and more time making things.

Phoenix is an experimental game, not a validated engineering or laboratory safety tool. Features and simulation behavior are still evolving.

Build. Observe. Try something else.

Good experiments start
with “what if?”

01

Keep your cool.

Connect a pump and pipes. Route fluid around a heat source. Watch the temperatures and refine your loop.

Explore cooling worlds ↗
02

Make the connection.

Place a battery, build a circuit and turn a simple switch into a more elaborate logic experiment.

Explore circuit worlds ↗
03

Look a little closer.

Mix a solution, add a measurement region and track the contents as you heat or cool your creation.

Explore chemistry worlds ↗

A work in progress. A world of ideas.

Help shape what comes next.

Read the development notes ↗

Your next idea might start here.

Discover experiments from other creators. Share your own, explain how it works and see what someone else makes of it.
