Conway's Game of Life

A self-contained, interactive implementation of Conway's Game of Life in a single HTML file — no dependencies, no build step.

Live Demo

Features

• Draw & erase — click or drag to place cells, right-click or drag to remove them
• Shape library — drag pre-built patterns (Glider, LWSS, Pulsar, Gosper Gun, Acorn, and more) onto the grid
• Speed control — adjustable simulation speed
• Density / zoom — scale the grid to fit more or fewer cells
• Generation & population counters — track the simulation in real time
• Keyboard shortcut — press Space to toggle play/pause

Usage

Open conway.html in any modern browser. That's it.

Rules

Each cell on the grid is either alive or dead. Every generation:

1. A live cell with 2 or 3 neighbours survives
2. A dead cell with exactly 3 neighbours becomes alive
3. All other cells die or stay dead
