Eight rule worlds
Compare Bloom, Orbit, Cells, Swarm, Rings, Maze, Bridge, and Void.
The living rule
Simple rules, surprising motion
Every dot follows nearby attraction and repulsion rules. Change the starting preset or one control, then watch local reactions grow into clusters, trails, and new patterns.

Result explanation
What you are seeing
Particle Life is not pre-scripted animation. Each colored dot belongs to a family. Families apply simple attraction or repulsion to nearby particles. Over time, those local rules create global behavior: clusters, streams, rings, membranes, and sudden collapses.
Clusters
Stable clusters mean several families found a temporary balance of attraction and repulsion.
Trails
Moving trails usually appear when one family chases another faster than it can settle.
Bursts
Pointer disturbance injects energy, giving the colony a chance to reorganize.
How it works
How the Particle Life Simulator Works
-
Choose a preset
Start with Bloom for soft, pulsing colonies, Orbit for rotating chases, Cells for membrane-like pockets, or Swarm for faster motion. Each preset changes the attraction and repulsion rules between particle colors, so it gives the same controls a different starting behavior. Use Reset after switching presets when you want a clean comparison from the same starting density.
-
Let families interact
The simulator evaluates nearby neighbors instead of directing the whole world from one central point. Every particle life simulation develops from those local reactions, which is why clusters, trails, rings, and sudden collapses can appear without a scripted animation. Because starting positions are randomized, repeating a preset can reveal a different structure.
-
Adjust density and energy
Particle count changes density and performance, Motion controls how quickly particles respond and travel, and Forces controls the strength of attraction and repulsion. Small adjustments usually make cause and effect easier to see than moving every control to an extreme. For a deeper explanation of how the live controls reveal each preset's internal rules, read the Particle Life parameter guide. On slower devices, reduce the particle count before lowering motion or force strength.
-
Disturb the habitat
Click, drag, or touch the canvas to scatter nearby particles and inject energy into the system. Then stop interacting and watch whether the colony rebuilds its earlier pattern, forms a new structure, or continues moving in a more chaotic state. Repeat the disturbance in different areas to compare recovery patterns within the same preset.
Online, mobile, and download intent
Built for quick browser play
This version focuses on a fast 2D particle life online experience. It runs locally in desktop and mobile browsers, requires no account or app download, and keeps every interaction on the current page. Lower particle counts usually provide smoother motion on older phones and laptops.
FAQ
Particle Life questions
What is Particle Life?
Particle Life is an artificial-life style simulation where colored particles follow simple attraction and repulsion rules. Those local rules can produce lifelike movement.
Is this particle life simulator free?
Yes. The V1 simulator is free and runs in your browser without an account.
Does Particle Life run on mobile?
Yes. The layout adapts to phone screens, and you can use touch input to disturb the colony. Lower particle counts usually feel smoother on older devices.
Do I need to download anything?
No. This is a particle life online simulator. It is designed to open directly in a browser.
