About

Conway's Game of Life is not a game in the traditional sense — there is no winning, no losing, and no player input after the initial setup. It is a cellular automaton: a grid of cells, each alive or dead, evolving according to four simple rules based on how many living neighbors each cell has. From these rules alone, extraordinarily complex patterns emerge.

The Game of Life produces stable structures (still lifes), oscillating patterns (blinkers, pulsars), and moving structures (gliders) from random starting configurations. Entire computational systems have been built within the Game of Life — it is computationally universal, capable of simulating any computer program given enough cells and time.

For a break, the Game of Life is contemplative and fascinating. Draw a pattern, press play, and watch what emerges. The browser version lets you experiment freely without any prior knowledge.

How to Play

• Click cells on the grid to toggle them alive (filled) or dead (empty).
• Press Play to start the simulation.
• Watch cells evolve: lonely cells die, overcrowded cells die, cells with 2–3 neighbors survive, dead cells with exactly 3 living neighbors are born.
• Pause at any time to modify the grid or study the current state.
• Try known patterns (gliders, oscillators) or create your own starting configurations.

Tips

• A glider is the smallest pattern that moves: 5 cells in an L-shape that travels diagonally.
• R-pentomino (5 cells in an irregular shape) produces hundreds of generations of chaotic evolution before stabilizing.
• Symmetric starting patterns often produce beautiful symmetric evolutions.

History

Conway's Game of Life was invented by British mathematician John Horton Conway in 1970 and published by Martin Gardner in Scientific American. Conway reportedly spent 18 months finding the exact birth/survival rules that produced the most interesting behavior before settling on the familiar 3/2,3 rule set. The game sparked enormous interest in cellular automata and complexity theory. Conway died in April 2020, the same month the COVID-19 pandemic accelerated, prompting many tributes.
