Conway’s Game of Life Simulator

Not the prettiest implementation of Conway’s Game of Life we have seen, but the most featured rich yet easy to use:

  • define your own patterns, or use a library of famous pattern
  • edit / draw / erase any pattern at any step
  • accelerate, back, zoom, …
  • large calculation grid (for an online implementation)

A very good start to learn many of the subtleties of  cellular automaton.

Disciplines: Mathematics, Computer science, Complex systems, Education.
Free alternative to Golly.

Delivery and installation: Runs in the browser through the embedded LifeViewer on conwaylife.com. Nothing to install, so it suits teaching and quick tests.Delivery and installation: A desktop application for Windows, macOS and Linux, with separate apps for iPad and Android. Version 5.0 was released in October 2025.
Rules and models: Focused on Conway Game of Life and related cellular automata. The site links to LifeWiki and Catagolue for known patterns.Rules and models: Supports Conway Life plus von Neumann 29-state, Wolfram 1D rules, WireWorld, Generations, Paterson Worms and Larger than Life. New rules can be added with RuleLoader.
Scale and algorithms: A large grid for an online tool, with drawing, erasing and step-back at any stage. Limits come from the browser.Scale and algorithms: Bounded and unbounded universes with up to 256 cell states, and several algorithms including Hashlife, which handles very large and long-running patterns.
Scripting and analysis: Interactive use only. Edits are made by hand on the grid.Scripting and analysis: Scripts in Lua or Python allow batch runs, pattern generation and measurements. This matters for research on complex systems.
Typical user: Students and newcomers learning how still lifes, oscillators and spaceships behave.Typical user: Researchers and advanced hobbyists searching for patterns or testing other automata rules.

Topics covered: cellular automaton, pattern definition, pattern library, editing tools, drawing tools, erasing tools, simulation acceleration, navigation controls, zoom functionality, calculation grid, user interface, feature-rich, online implementation, algorithm efficiency, iterative processes, mathematical modeling, computational theory, ISO/IEC 25010, ISO/IEC 9126, IEEE 829, ISO 9001, and ISO/IEC 27001..
