Cellular Automata

Conway's Game of Life and Beyond

A zero-player game where cells live, die, and reproduce based on simple rules. Change the birth and survival conditions to discover entirely new universes. The default rules (B3/S23) are Conway's classic, but there are hundreds of others hiding in the toggles below.

Click to draw cells. Select a pattern from the library below and click anywhere on the grid to stamp it down. Right-click or Escape to cancel. In infinite mode, shift-drag to pan and scroll to zoom.
